|A Diabetes Diet is Different from and Easier than a Weight Loss Diet|
Weight Loss Diets Usually Fail but Diabetes Diets Can't Afford To Fail. The stakes are too high!
Did your heart sink when you learned that the best way to control diabetes was with "diet?" Of course it did. Almost everyone diagnosed with Type 2 diabetes has a long history of trying to diet off weight and failing miserably. If you believe that your health depends on even more dieting, it is easy to give up hope.
But it turns out that a diabetes diet is very different from a weight loss diet of the sort you can see illustrated in the photo above. The point of a diabetes diet is not to lose weight. The point of a diabetes diet is to bring your very high post-meal blood sugars down into the normal range. You can eat as much food as you want on a diabetes diet, as long as the food you eat is food that doesn't raise your blood sugar.
In fact, if you adopt a diabetes diet you may actually find yourself losing some weight, because high blood sugars make us more insulin resistant and that causes weight gain. But there's another reason why diabetes diets can help you lose weight without trying: when you flatten out your blood sugar after meals, you eliminate the overwhelming hunger that comes with blood sugars that go very high and then drift back down. When you aren't starving all the time, losing weight is a lot easier.
But that's just a nice plus. You can eat a totally successful diabetes diet that gives you back your health without losing a pound, and more importantly, you can eat that diet year in and year out without making yourself crazy or feeling continually deprived. Here's how.
The Diabetes Diet is All About CarbohydratesIt is the carbohydrates you eat that raise your blood sugar. If you cut back on carbohydrates, your blood sugar will come down. It's that simple. Solid research has proven that it is not eating fats that raise cholesterol, either, but eating carbohydrates which convert into dangerous triglycerides. So while it is true that eating fats along with carbohydrates is very unhealthy, the less carbohydrate you eat, the more fat you can eat safely.
How Many Grams of Carbs Should You Eat? As Many as Allow You to Reach Your Blood Sugar TargetsWhen people think about adopting a lower carb diet, their first question is almost always, "How many grams of carbs can I eat at each meal?" Most of the diet books will answer that question with a hard and fast number. Atkins, for example, tells you to start out with 20 grams a day. Protein Power, a healthier low carb diet than Atkins, starts you at 30 grams. And Dr. Bernstein suggests you eat no more than 6 grams for breakfast and snacks and 12 grams at lunch and dinner.
Adopting these very low carbohydrate limits will control your blood sugar very nicely. But over time, many people find that sticking to a diet this low in carbohydrate becomes impossible.
That's why I'm going to ask you to throw away all those diet books and try a new approach to restricting carbs.
What you will do is to try the strategy used by the people who used to hang out on the alt.support-diabetes newsgroup and call themselves The 5% Club because eating that way, their A1c test results fell in the 5% range which doctors consider normal.
You'll find this simple technique described here:
How to Get Your Blood Sugar Under Control
Use your blood sugar meter after each meal as described in the link above to determine how many grams of carbs you can eat and still meet a healthy blood sugar target.
You will start out by measuring your blood sugar one and two hours after each meal. Write down what you ate and observe what it did to your blood sugar. If a meal allows you to reach your blood sugar targets, try eating it again on a different day and test it test again, possibly at a later time, to make sure that your good numbers weren't just a result of slow digestion.
If you end up too high after a meal, the next time you eat it, cut back on the portion size of the carbohydrate-bearing foods in the meal and test again. Do this until you can hit your targets, or flag the carbohydrate-containing foods in that meal as ones your body can't handle and replace it with something else.
You'll find suggestions for foods that won't raise your blood sugar here:
What Can You Eat When You Are Cutting Carbs?
What you're doing here is creating what Australian Diabetes activist Alan S. calls, A low spike diet rather than a low carb diet. How many grams of carbohydrates will cause you to spike varies from person to person. Alan can achieve normal post meal blood sugars by eating as many as 30 or 40 grams of carbohydrates at a meal. Others will find that they need to eat a lot less than that amount to hit safe post-meal blood sugar targets.
Hhow much carbohydrate you can manage depends your body size and muscle mass as well as on how damaged your beta cells are. The more you weigh or the more muscle you have, the less each gram of carbohydrate you eat will raise your blood sugar. Because of this, men can usually eat more carbohydrates and still reach their targets than can women
How to Learn How Much Carbohydrate is in Your FoodTo make this system work, you must learn how many grams of carbohydrate are in normal portions of the foods you eat. That way once you've learned how a representative sample of foods with known amounts of carbohydrates in them affect you, you won't have to test hundreds of other foods.
The best way to learn how many grams of carbohydrates are in the different foods you eat is to read food labels carefully, invest in a nutritional guide like The Complete Book of Food Counts, , ,or use online calculators like that found at Fitday.com or My Fitness Pal which will also work on your smart phone. Software and online sites will compute the amount of carbohydrates and other nutrients in your meal for you as long as you know the portion size.
Learn about Portion Sizes!This brings up an important point: When you estimate how many grams of carbohydrate there are in a portion of food, it is very important to find out if the amount of food on your plate corresponds to the amount in the "one serving" listed on a label, in a book, or in your software.
The best way to do this is to invest in an electronic food scale and to weigh your foods for a few weeks until you get the hang of estimating portion size. You can get a good food scale at a gourmet kitchen shop for $25 to $40 dollars. You'll find a link to the scale I use on this resources page.
This food scale may be the best nutritional investment you'll ever make. Once you start using your scale, you will find that the muffin you bought at the coffee shop weighs 8 ounces, which is fully four times the 2 ounces that most food databases give as "one serving" of a muffin. When you read that a mythical 2 ounce portion of muffin contains 27 grams of carbohydrate you will realize why that 8 ounce coffee shop muffin with its 108 grams of carbohydrates sends your blood sugar into the psycho zone!
With ice cream, when you weigh your ice cream on a food scale, you'll quickly see that the "one portion" listed on the package turns out to be only a few teaspoons' worth. That bowl you've been considering as one portion of ice cream weighs in as four servings or 72 grams of carbohydrate and 600 calories, which may explain its damaging effect on both your blood sugar and your waistline.
This may sound like a lot of work, and when you first start, it is. But after you do it for a few weeks you'll find you have memorized the carbohydrate gram counts and the portion sizes for the foods you usually eat, and once you have tested your blood after eating these portion sizes, you won't have to test every time you eat a favorite meal, because you will know what it is going to do to your blood sugar.
Eating Away from HomeThe biggest challenge you'll encounter as you start learning what you can eat will be eating away from home. You aren't going to be able to weigh restaurant foods nor can you look up the nutritional values of many restaurant offerings--though many of the common fast food outlets do provide nutritional information online--though often without listing portion sizes.
That makes it a very good idea to avoid starchy or sugary restaurant foods or, if you do eat them, to eat only a small portion of what you are offered. Measure your blood sugar an hour or two hours after eating if you aren't sure about how a restaurant food will affect you.
Don't Trust Nutrition Data Provided by Restaurants. When television stations went out and had chain restaurant food tested at a lab in 2008, they learned that the calorie and fat counts were significantly understated. Some foods had as much as 40% more calories per portion than the menu claimed. The TV stations were defining "diet" as low fat/low calorie and didn't report on carbs, but you can be sure they were higher too.
Diabetes in Control: Donít Depend on Restaurant 'Diet' Menus
Fat and Carbs Eaten Together will Digest SlowlyFoods with a lot of fat in them take longer to digest than those without a lot of fat. This is why pizza and ice cream often give deceptively good readings on your meter. If you test a meal and see a reading that is too good to be true, be sure you test at 3 or four hours after eating.
The Truth About PastaPasta was long recommended to people with diabetes as a food that would not raise blood sugar and you will still see it starring in many cookbooks and magazines intended for people with diabetes.
However, if you test pasta 4 or 5 hours after eating, you may get an unpleasant surprise. This is true with the so-called "low carb" pastas, too. These foods give you excellent readings at one and two hours because they are resistant to digestion so they don't turn into glucose right away. But five hours later, they do break down into glucose and when they do, the 52 grams of carbohydrates found in each 2 ounce serving of pasta will hit your blood stream with a nasty wallop. (Not to mention that you almost need a microscope to see a 2 ounce portion of pasta. Most people's idea of a portion of pasta is closer to 6 ounces--and 156 grams of carbohydrate!)
If you have pasta for dinner and don't see a peak 3 hours later, be sure to check your fasting blood sugar the next morning. You may see the blood sugar rise there, too.
Sugar Alcohol and "Sugar Free" FoodsThe sugar alcohol used in so-called "sugar free" foods can also show up in your blood sugar an hour or two after you'd expect to see them, especially the maltitol used in "sugar-free" candy. At least half of the sugar in maltitol does turn into glucose in your blood stream and it can raise your blood sugar, but the rise is delayed so you may miss it on testing. So if a "sugar free" food seems to be kind to your blood sugar, try testing it an hour or two after your first tests. Erythritol is the one sugar alcohol that usually does not show up in your blood sugar.
Dealing with Limited Blood Testing SuppliesIn in ideal world, we'd all have all the testing supplies we needed to control our blood sugar, but in real life blood sugar test strips are very expensive and many insurers sharply limit the number of strips people with Type 2 diabetes can get each month.
Here are some strategies that can help you if your access to strips is limited.
- If you only have 50 strips to get you through a month, plan out what you are going to test ahead of time. Pick one of your favorite meals, and test at 1 hour after eating the first time you eat it and 2 hours after eating the second. Do this with a couple different meals and see if there's a pattern as to when you see the highest reading--whether it is at one hour or two. Then choose another meal and test it at the time when you saw the highest reading in the earlier meal. If you ever get a surprisingly low reading, try testing an hour later or earlier, to make sure you aren't missing the peak.
- Make the goal of your testing be learning how many grams of carbs you can tolerate in one meal. If you learn that 30 grams is your upper limit, use software and your scale to find portions of other foods that will also clock in at 30 grams or less. Test one or two of these, and if you see the result you expect, you don't have to test every time you eat these foods again.
- Wal-Mart sells a cheap and effective blood sugar meter with strips that cost one half as much as other vendors. Some drug stores also sell store brand meters with cheaper strips. If you need more strips, consider the $50 you pay for another 100 strips an investment in your health. It's far better to spend that $50 now, than to spend it on expensive doctor bills caused by complications you don't need to develop!
Keep the focus on Achieving your Blood Sugar GoalsBy testing after meals, you'll learn how many grams of carbohydrate your own, unique, body can handle. And more importantly, you'll also be able to decide if you are going to be able to control through diet alone, of whether it is time to talk to your doctor about supplementing dietary control with drugs.
Many people are so excited to learn that they can achieve normal blood sugars by cutting way back on carbohydrates that they become zealots for low carb dieting. I've been there and I've done that. But it's important not to get too carried away with a "Carbs are Evil" mentality which makes it a matter of religious zeal never to let evil carbs cross your lips again. Like all conversions this one tends to fade out in time. And as we said at the start of this chapter, your ultimate goal is to maintain your blood sugar targets for the rest of your life. So the safest approach is to get the most blood sugar benefit you can out of restricting carbohydrates, but restrict them to a level you can maintain year in and year out.
Most importantly, I have learned it is best to treat carb restriction as a strategy, one of many, which used in combination with other strategies including medications if needed, can give you normal blood sugars, rather than the One and Only True Way. If you can be flexible and find more than one tool to help you meet your blood sugar targets, you are more likely to be able to maintain those excellent blood sugars for years to come.
To remind you again, here are some suggested blood sugar targets. There's some discussion about whether to measure from the beginning or end of your meal. I measure from the end, which works well because recent studies show the actual peak for fast carbohydrates is about 75 minutes after ingestion.
|Normal ||5% Club||AACE|
|1 Hour After Meal||100 mg/dl (5.6 mmol/L)||Under 140 mg/dl (7.8 mmol/L)||Not Given|
|2 Hours After Meal||85 mg/dl (4.7 mmol/L)||Under 120 mg/dl (6.7 mmol/L)||Under 140 mg/dl (7.8 mmol/L)|
Eliminate "Habit Carbs" and Concentrate on "Value Carbs"When people think about restricting their carb intake they assume this means never eating any of their favorite foods again.
But for many of us, this doesn't have to be true. Why? Because a quick look at your daily carb intake will often reveal that the bulk of the carbohydrates you are eating are what I call "habit carbs." These are the carbs you eat without a second thought because they are there. Not because they taste good. Not because you couldn't live without them. Just because you're in the habit of eating them.
Here is a list of some prime "habit carbs."
- Steam table mashed potatoes
- Limp french fries
- Squashy hamburger buns
- Cardboard toast
- Cold home fries
- Stale boxed cookies
How many of these flavorless, starchy foods are you consuming everyday just because they're there? Probably more than you realize. So before you lift that fork-full to your mouth, ask yourself, "Is this food thrilling me?" If not, put it down. This should go a long way towards getting your carb intake down.
What I'd call "value carbs" are those carb-rich foods that really do mean something to you. I'm not going to lie to you. You are not going to be able to make them the mainstays of your diabetes diet. But by using the strategies describe below, you should be able to eat enough of these foods to keep yourself from feeling deprived--without destroying your health.
Don't Create "Forbidden Foods!" If you are one of those people who could live happily on Purina People Chow, you can skip what follows. But if food has been important to you, and if you have hitherto had a long and emotionally satisfying relationship with food, or if, like me, baking from scratch was one of your favorite ways to show love and express creativity, restricting your carbohydrate input will mean that a whole lot of what you've been eating (and baking) up until now is suddenly, completely, off limits. I can't eat cake and get a healthy blood sugar level. Even with two different diabetes drugs in my system. I can't eat cake even with an insulin shot before I eat it. I love cake but there is no way I can eat more than a bite or two without seeing very high blood sugars and there is no way I can eat two bites of cake and be happy. The same goes for french fries and Thai noodles.
During the first enthusiastic weeks of exploring carb restriction most people deal with this kind of discovery by coming up with new recipes and finding new, delicious and healthy things they can substitute for old, high carb standards. They appreciate the way cutting way back on carbohydrates curbs their hunger and makes food much more manageable. This is good and it is why long term low carbing is possible. But our old favorite foods do not go away that easily.
If you decide that some food you have been eating and enjoying all your life will never again cross your lips, it is almost 100% guaranteed that you'll end up pigging out on that very same food at some time in the future, hating yourself, and even beginning a binge that can throw you completely off your diet for months.
It might not happen the first month you are restricting your carb intake or even the first year. It took me three years of low carbing to get to where I crashed off my stringent low carb diet. But eventually it happens, and because after almost a decade of counting my carbs I've learned that I will never lose my love for certain foods that don't love me, I've put a lot of time into finding a way of restricting my carbohydrate intake in a way that avoids the buildup those feelings of deprivation that eventually lead to long periods of unwise eating.
The key, for me, is to build safety valves into my diet. I don't call them "cheats" or "bad foods" for reasons I'll get into later. I call them "off plan" foods because they are not food I can make an ongoing part of my daily food plan. Because my goal is life-long blood sugar control, I accept that I will occasional eat "off plan" and that this is okay as long as I am meeting my blood sugar targets most of the time. "Good enough" control that I can adhere to year in and year out beats a few months of perfection followed by crashing off the diet entirely and ruining my health. Here is one way to approach doing this:
Do the Diet Straight for a Month or Two Before You Try Off-Plan GoodiesAs you learn what foods raise your blood sugar and what foods don't, you will almost certainly find that there are a lot of foods you used to love that don't work for you anymore. Waffles for breakfast, coffee cake at coffee break, three slices of pizza with crust, a burger with a bun and a side of fries are just a few of the foods that it is almost certain will not allow you to meet your post-meal blood sugar targets.
As you keep using your meter to test what you eat, if you are like most people with diabetes you'll also learn that some of the so-called "low glycemic" foods and the supposedly "healthy" whole grains that nutritionists recommend for people with diabetes won't work either. Oatmeal and whole wheat bagels raise my blood sugar far too high, so does cracked whole wheat, whole wheat bread, and brown rice.
If the dietitian tells you a food is good for you, but your meter tells you it is raising your blood sugar to a level that is high enough to cause complications, you will have to listen to your meter. Your meter will tell you what is safe to eat and for the first couple of months while you are learning how to get your blood sugar under control and how bring those high blood sugars down to normal levels you will have to accept that you can only eat those foods that don't cause spikes.
If you attempt to add in off-plan foods before you are solidly on-plan you may never really get into the swing of eating a diet that controls your blood sugars and you may not get to where your body learns to enjoy the lower carb foods that don't give you blood sugar swings.
But after you've gotten your blood sugar under control, nothing horrible will happen if you make room for a small portion of some high carb treat every now and then.
How to Add Off-Plan Foods to the PlanIf you've avoided bread for a couple months, the humble roll in that restaurant bread basket may start to call out to you with an irresistible siren song. If you give in and eat it, with each bite you may find yourself feeling as if you are doing something incredibly sinful--the way you might have felt if you had eaten a whole box of chocolates in the past.
That feeling is the sign that you're heading for trouble. You've created a "forbidden fruit" and sooner or later that forbidden fruit is going to get you. You may find yourself thinking about that roll, craving another, sneaking off to eat one where nobody knows you, or, alternatively, you may declare that you will never again eat a roll ever--and then ruin your Thanksgiving holiday when you go to Aunt Glenda's and refuse to eat even a single one of those wonderful rolls of hers you've eaten every year of your life which say, "This is the family Thanksgiving" to you.
It is far better to make a bit of room in your diet for high carb treats so that they don't build up a charge. If you do this, you'll find that they almost never taste as good as you remembered, and you'll be able to leave them behind without turning them into an object of obsession.
Just knowing that you can eat some specific off-plan food at some future time, when it is scheduled, makes it that much easier to say, "No thanks" to it, and maintain your healthy blood sugar the rest of the time.
How Often Can You Eat Off-Plan?How often you have an off-plan food depends a lot on your dietary goals, how high your blood sugar is before you eat carbs, and whether you are willing to exercise after eating. It also depends greatly on what medications you are taking for your diabetes. Whatever I eat, I try to keep my blood sugar below 120 mg/dl (6.7 mmol/l) at 2 hours after any meal.
Forty minutes of cardiovascular exercise will burn off a lot of extra carbs, so if you exercise regularly, try to eat your high carb treat before you head for the gym.
If you're trying to lose weight, you may have to keep off plan treats few and far between. When I was actively losing weight on a low carb diet without medications I ate one off-plan meal about once every two weeks.
Once I reached my weight loss goal I loosened up a bit but I found it best to cycle between weeks of eating a strict very low carb diet, and then a week of eating slightly more carbs--but I tried very hard not to ever anything that would cause my blood sugar to be over 120 mg/dl (6.7 mmol/L) at 2 hours after a meal because doing so makes me feel rotten.
Throw Away the Vocabulary of Self-Destructive DietingWhen you eat something with carbs in it, don't think of it as a "cheat." Cheating is what you do when faced with an authority figure--your 9th grade math teacher or the IRS. But you are the one in control of what you eat. So when you eat something that is off-plan, you should stop thinking of it as "getting away with something" and treat it instead as something you've decided to do--for a reason that should be clear to you while you do it.
If you keep eating things that were not what you had intended, rather than beating yourself up, it's time to reconsider your food plan and figure out why it isn't working. Are you having trouble finding foods in restaurants that don't raise your blood sugar? Maybe it's time to bring your lunch along to work for a while, or to find new place to dine.
Are you bored with what you have been eating? Google for good low carb recipes you can try at home. There are thousands of them. If you use the Google Groups search and look for messages in alt.support.diet.low-carb that start with "REC" you'll find a treasure trove of ideas to try.
Keep the vocabulary of sin and guilt for the confessional. You're going to eat a lot of things in the years to come that will mess up your blood sugar. But if you are kind to yourself and dust yourself off after you mess up and keep on going, doing the best you can to hit your blood sugar targets, you may very well end up healthier than many people who do not have diabetes. The important thing is to keep at it, doing the best you can and forgiving yourself when the best you can do isn't as good as you wish it was.
Know Your LimitsI've learned the hard way I can't eat half a blueberry muffin, so I don't even try portion control for that particular food. I know blueberry muffins are trouble and I also know that I will eventually eat one. That's just how it is, so every blue moon or so I eat a blueberry muffin, experience the miserable high blood sugars that follow, and then remember why I don't eat muffins every day any more. What I don't do is fool myself that I can buy a muffin and only eat half. Everyone has a few foods that fall into this category. Treat them with caution!
Eat Off-Plan Foods Out of the HouseI've learned the hard way that if a big box of something full of carbs is in the fridge, bad things are going to happen. So I try to eat my off-plan foods away from home. I eat my muffins or cookies at a coffee house. I have a slice of pizza at a pizzeria. I don't buy a box of muffins or a whole pizza and bring them home.
Getting this strategy to work requires that your whole family understand what's at stake. It took me a couple years of harping on what "complications" means, but by now, my family understands that if my blood sugar is too high, I'm damaging my body. They want to keep me around for a while, so they understand that there are some foods that shouldn't be brought into the house--ever.
When other family members want to have treats at home, they are kind enough to buy things I don't like. For example, if someone wants Ben & Jerry's they buy the Chunky Monkey flavor that I find revolting, not the New York Fudge. By the same token, when my kids lived at home, I didn't buy them the brands of cookies I can't resist. There are plenty of others cookies they liked that don't tempt me at all, and those were the ones in the cupboard.
Over the years the nondiabetic members of my family learned that no one is doing themselves a favor scarfing down 300 grams of fast acting carbohydrate every day--particularly not people with a family history of diabetes and heart disease!
Medications Can HelpI'm not a big fan of medications because I've learned the hard way that drug companies lie about side effects and some of these side effects are permanent and can ruin your life. But I learned the hard way, too, that some of us (like, say me) can't get normal blood sugars no matter how low our carb intake. For us, adding a diabetic drug or two to our daily regimen may be the only way we can get normal blood sugars without a life of tormenting self-denial.
Drugs I have found useful over the years include metformin, Precose, and post-meal insulin shots. Byetta helps some people make dramatic improvements in their blood sugar and weight, though it is worth noting that the way that Byetta works makes it necessary to eat a slightly higher amount of carbohydrates with it because it only causes insulin secretion if your blood sugar goes up over a threshold--around 120 mg/dl (6.7 mmol/L) for me. Even with all these drugs I've never been able to eat more than 120 grams of carbohydrates a day and keep good control, but after many years of eating an extremely low carb diet--which was the only diet that would control my blood sugars before I was given insulin--120 grams of carbs a day feels like a completely normal diet!
Be Aware of Rising Insulin ResistanceSome people may find that eating a low carb diet is not enough to control their blood sugar because they are very insulin resistant. Perhaps they have been diagnosed with PCOS, or have to take a drug, like Prednisone that increases insulin resistance. The book, Dr. Bernstein's Diabetes Solution by Dr. Richard K. Bernstein, the distinguished diabetes doctor, recommends Metformin as an appropriate drug for patients on a low carb diet whose blood sugars are still not completely controlled. It isn't a cure by any means, just one more tool you can use to keep blood sugars under control, and if you limit your insulin resistance you may solve both weight and hunger problems that otherwise can derail your diet.
You can read more about the different drugs available to help control blood sugars HERE. Just remember that all these diabetes drugs work best when you combine them with some level of carbohydrate restriction. How much restriction? Test your meals one and two hours after eating, and your blood sugar meter will tell you exactly how much.
Top Medical Journal Publishes Landmark Study Showing Very Low Carb Diet Most Effective and Safest for Lipids etc.In case you are still being given out-of-date medical or nutritional advice by people who tell you that a low carb/high fat diet will give you a heart attack, take a look at this recently published study, which appeared in the Journal of the American Medical Association.
This study found that an Atkins style low carb diet not only caused double the weight loss of the low fat diet at the end of one year, but it did not adversely affect cholesterol levels.
This finding, added to the Women's Health Initiative finding (after $40 million dollars of research) that low fat dieting does NOT prevent heart disease, should lay to rest any last fears you might have about the impact of cutting carbs on your health.
The findings of this study, are not news to anyone who has tried a low carb diet and stuck with it for any period of time, but they appear to amaze the entire medical community who continue to cling to their to the "Fat is Bad" religious belief long no matter what evidenced-based medical studies might come up with.
Bottom line: You can cut your carbs way down, replace carbs with fat, and await the better health this kind of eating will provide.
