The Holy Grail: Prevention of Weight Regain

Losing excess weight is easier than keeping it off.

Neither is exactly a walk in the park.

Prevention of weight regain is the most problematic area in the field of weight management.  You may have heard that “diets don’t work,” but they do.  Many different weight loss programs work short-term, if “work” is defined as loss of five, 10, or more pounds while you adhere to the program for several weeks or months.  The problem is that the lost pounds usually return.

Why?  You get bored with the diet, or your willpower flags, or the diet simply stops working, or the transition from weight loss to maintenance is unclear, or you just feel too bad to go on, or you lose your commitment, or you take a job as a taste tester for Baskin-Robbins Ice Cream, or whatever. 

Most diets ultimately fail in the long run because people go back to their old habits. 

Read on for the secret to prevention of weight regain.  They apply to a majority of weight-loss methods, although many programs ignore this problem because the cure is a hard pill to swallow. 

Moving Ahead

For purposes of further discussion, I will assume that you have already lost excess weight down to your goal and now we must focus on staying thereabouts from here on out.  Finally down to your goal!  A grand accomplishment!  You’ve got a new wardrobe, or the old clothes fit again.  You have more energy and feel younger.  Maybe you cured or improved some health problems.  Perhaps you’re getting more attention from the opposite sex (ooh la la!). 

Our species’ scientific name is Homo sapiens.  It is from the Latin sapere, which means “to be wise.”  Wisdom is the ability to make correct judgments and decisions.  Undoubtedly, your success at weight loss required correct judgments and decisions.  You are not done yet.  You will need sustained wisdom to avoid weight regain.

Be wise about this especially: you can never again eat all you want, whenever you want, over sustained periods of time.  

Now that you have reached your goal weight, you must restrain yourself on a daily basis.  Think about it.  You became overweight because you didn’t watch what you ate and didn’t exercise enough.  You can’t go back to your old ways.  Reject this advice, and you have a 100 percent chance of regaining your lost weight. 

Have you heard of the Energy Balance Equation?

Calorie Intake minus Calories Burned

         =  Change in Body Fat

You have been able to lose fat weight because you ate less energy (calories) than your body required for metabolism and physical activity.  Your body remedied the energy deficit by converting fat into energy.  A pound of fat contains 3,500 calories of energy.  If you lost a pound per week, your body on average converted 500 calories of fat daily into energy (7 days x 500 calories = 3,500 calories = 1 pound of fat). 

Now that you are at your goal weight and want to stay there, you need to add 500 calories per day back into the equation.  Add the calories by eating more food, exercising less, or a combination of the two. But if you add back more than 500, you will regain weight.

The true measure of a successful weight management program is not simply how much weight is lost, but whether the lost weight stays lost over the long run.  What distinguishes weight losers who keep the weight off from those who gain it back?  Two factors, mostly:

          1.  Restrained eating
          2.  Regular physical activity
.

“Successful losers” apply self-restraint on an almost daily basis, avoiding food that they know will lead to weight regain.  They limit how much they eat.  They consciously choose not to return to their old eating habits, despite urges to the contrary.  The other glaring difference is that, compared to regainers, the successful losers remain physically active.  They exercised while losing weight, and continue to exercise in the maintenance phase of their program.  This is true in at least eight out of 10 cases.  It’s clear that regular exercise is not always needed, but it dramatically increases your chances of long-term success. 

In a nutshell, my maintenance phase prescription for you is: Keep exercising, and eat a little more.  Keep exercising, and eat a little more.

Go out of your way to be physically active for 30 to 45 minutes on at least four days per week, if not all days.  Walking is fine.  The more you exercise, the more you can eat without getting fat again. 

At the end of your weight-loss phase and the beginning of the maintenance phase, it is surprisingly easy to start overeating.  Forewarned is forearmed.  Avoid this landmine any way you can.  It helps to continue monitoring food consumption and exercise on your food diary while eating an additional 200–500 calories per day.  Continue weighing daily.  Keep exercising.  After a month or two of this regimen, you’ll have an intuitive sense of what and how much you should be eating without regaining weight.  Then stop the daily log routine. 

Another option for transition to the maintenance phase: if you have been exercising regularly but loathe it, you could stop exercising and stay on your current calorie level diet.  In other words, don’t start eating more.  See what happens with your weight.  Perhaps you could later eat an extra 100 to 200 daily calories without gaining weight.  Continue recording your daily intake and weight for a couple months.  

Weigh yourself daily during the first two months of your maintenance-of-weight-loss phase. After that, weigh weekly.  Daily weights will remind you how hard you worked to achieve your goal.  When you look now at a brownie, candy bar, or piece of pie, you ask yourself, “Do I really want to walk an extra hour or jog an extra three miles today to burn off those calories?” If so, enjoy. Otherwise, forego the unneeded calories. 

Be aware that you might regain five or 10 pounds of fat now and then.  You probably will.  It’s not the end of the world.  It’s human nature.  You’re not a failure; you’re human.  

But draw the line and get back on your old weight-loss program for one or two months.  Analyze and learn from the episode.  Why did it happen?  Slipping back into your old ways? Slacking off on exercise?  Too many special occasion feasts?  Allowing junk food back into the house?  Learn which food item is your nemesis—the food that consistently torpedoes your resolve to eat right.  For example, I have two—candy, and sweet baked goods such as cookies and muffins.  If I just look at them I add a pound.  Remember an old ad campaign for a potato chip: “Betcha can’t eat just one!”?  Well, I can’t eat just one cookie.  So I don’t get started.  I might eat one if it’s the last one available.  Or I satisfy my sweet craving with fresh fruit or a diet soda.  Just as a recovering alcoholic can’t drink any alcohol, perhaps you should totally abstain from…?  You know your own personal gastronomic Achilles heel.  Or heels.  Experiment with various strategies for vanquishing your nemesis. 

It’s OK to overindulge in food infrequently (10–12 times per year), on special occasions such as birthdays, wedding anniversaries, holidays.  But you must counteract the extra calories by cutting down intake or by exercising more, either before or after the feast.  No big deal.

FDA Warns About Lipodissolve

I wrote elsewhere about mesotherapy (also known as lipodissolve) in April, 2008.  It’s a technique designed to “dissolve” localized fat deposits under the skin.

The U.S. Food and Drug Administration this month is alerting consumers that

  • it has not evaluated or approved products for use in lipodissolve
  • it is not aware of evidence supporting the effectiveness of the substances used in lipodissolve for fat elimination
  • the safety of these substances, when used alone or in combination, is unknown
  • it is not aware of clinical studies to support medical uses of lipodissolve

In addition, FDA has reports of unexpected side effects in people who’ve undergone the lipodissolve procedure. These side effects include

  • permanent scarring
  • skin deformation
  • deep, painful knots under the skin in areas where the lipodissolve treatments were injected

This is good to know before you invest time and money in the procedure.

Cinnabon Schninnamon

I woke up today and found my wife had brought home six Cinnabon cinnamon rolls.  I had mentioned off-hand a few days ago how much I missed them.  She interpreted that as a request [it wasn’t].

I couldn’t say “no” now, could I?

No, I couldn’t.

According to Calorie Count, the classic Cinnabon roll provides:

  • 730 calories
  • 216 calories from fat (24 g)
  • 114 g of carbohydrate
  • 1.5 g fiber

Looking at the carb count, you can understand how the typical American gets 250-300 g of carb daily.  For the last nine months, I’ve been eating 50 g or less, and about 2000 calories/day.

I ate the Cinnabon as a meal, rather than as dessert after—and in addition to—a meal.  If you’re gonna cheat during a weight-control program—and who doesn’t?—that may be a good way to do it.

Compare the Cinnabon with a 700-cal large green salad with tomato, onion, olive oil vinaigrette, topped with tuna or chicken.  Which has “more nutrition”? 

Did I enjoy the Cinnabon?  You bet!  Will I be able to resist the temptation of the ones remaining?  I hope so.

London’s Low-Carb Diet Fad of 1865

Dr. Robert Atkins didn’t invent low-carb dieting.  William Banting (1797-1878) sparked a low-carb diet craze in London with his low-carb weight-loss diet, first published in 1863.  Even that probaby wasn’t the first low-carb diet.

According to Wikipedia, Banting was a distant relative of Frederick Banting, the co-discoverer of insulin in 1921.

Mr. Banting attributes his successful program design to a “medical gentleman,” Mr. Harvey, of Soho Square, London.

Individual Response to Weight-Loss Diet May Depend on Genes

Dieters with particular genetic make-up respond better or worse to specific types of weight-loss diets, suggest researchers who presented data at the 2010 Cardiovascular Disease Epidemiology and Prevention /Nutrition, Physical Activity, and Metabolism conference.  Findings are preliminary, but may explain the common phenomenon of two people going on the same diet, but only one achieving good results. 

I’ll bet you can imagine several other explanations.

Several years ago, the “A to Z” study compared the weight loss of 311 overweight women on one of four diets:  Atkins (low-carb), Ornish (very low fat, vegetarian), Learn (low-fat), and Zone (moderate carb restriction, high protein, moderate fat).  Atkins was a bit better than the other diets, in terms of long-term (one year) weight loss.  But within each diet group, some women lost 40–50 pounds (18–23 kg), whereas others gained over 10 pounds (4.5 kg).

Stanford University researchers obtained DNA from 138 of the 311 women and noted the occurence of three genes—ABP2, ADRB2, and PPAR-gamma—that had previously been shown to predict weight loss via diet-gene interactions.  For example, a particular mix of these genes predict better weight loss with a low-fat diet; a different mix predicts more loss with a low-carb diet.

Women who had been randomly assigned to one of the A to Z diets tended to lose much more weight if they happened to have the gene mix appropriate for that diet (compared to those on the same diet with the wrong gene mix).  The difference, for example, might be loss of 12 pounds versus two pounds.

The lead researcher, Dr. Mindy P. Nelson, told TheHeart.Org that the proportion in the general population genetically predisposed to the low-fat versus low-carb approach is about 50:50.

Take-Home Points

These results, again, are preliminary; additional testing is necessary for confirmation.  If they had been able to test the DNA of the other 178 women in the A to Z study, the results could have been either stronger or shown no diet-gene interaction.  The study hasn’t even been published in a peer-reviewed journal yet.

Men may or may not be subject to similar diet-gene interaction.

If a genetic test is ever clinically available to tell a dieter which type of weight-loss diet would be more successful, it will likely be cheaper to just try a particular diet first and see if it works over 4–6 weeks.  Successful long-term weight loss is like smoking cessation—most smokers try 5–7 different times or methods before hitting on one that works for them.

This potential diet-gene interaction could be a major finding that will stop the arguing about which is the single best way to lose excess fat.  Many paths may lead to the mountaintop.

Prediabetes Ignored Way Too Often

Only half of Americans with prediabetes take steps to avoid progression to diabetes, according to a recent report in the American Journal of Preventive Medicine.

Prediabetes is defined as:

  1. fasting blood sugar between 100 and 125 mg/dl (5.56–6.94 mmol/l) or
  2. blood sugar level 140–199 mg/dl (7.78–11.06 mmol/l) two hours after drinking 75 grams of glucose

Prediabetes is a strong risk factor for development of full-blown diabetes.  It’s also associated with increased risk for cardiovascular disease such as heart attack and stroke.  One of every four adults with prediabetes develops diabetes over the next 3 to 5 years.  The progression can often be prevented by lifestyle modifications such as dietary changes, moderate-intensity exercise, and modest weight loss.  

Investigators looked at 1,402 adult participants in the 2005-2006 National Health and Nutrition Examination Survey (NHANES) who had fasting blood sugar tests and oral glucose tolerance tests diagnostic of  prediabetes.  

The researchers estimate that 30% (almost one out of every three) of the adult U.S. population had prediabetes in 2005-2006, but only 7% of them (less than one in 10) were aware they had it.

Only half of the prediabetics in this survey reported attempts at preventative lifestyle changes in the prior year.  Only one of every three prediabetics reported hearing about risk reduction advice from their healthcare provider.

People, we’ve got to do better! 

My fellow physicians, we’ve got to do better!

The U.S. Centers for Disease Control and Prevention predicts that one of every three Americans born in 2000 will develop diabetes.  The great majority of this will be type 2 diabetes.  You understand now why James Hirsch, author of Cheating Destiny, calls diabetes America’s leading public health crisis.  I agree.

Do You Hari Hachi Bu?

I loved the sound of this phrase—hari hachi bu—even before I knew what it meant.

“Hari hachi bu” comes from the Japanese islands of Okinawa.  It refers to eating a meal until you’re only 80% full, then stop eating.  It’s a method to control weight. 

Okinawa, remember, is one of the longevity hot spots in Dan Buettner’s Blue Zones

But would it really work for many in Western culture?  Probably not.  We don’t have the discipline to stick with it long-term.  Maybe for a day.

One of the currently popular dieting gimmicks is to eat every 3-4 hours while awake.  The rationale is, “you need the energy.”  If you eat 5–6 meals a day, you’re not cutting back on total calories even if you eat only until 80% full.

As long as you’re eating a fair amount of carbohydrates, you can store plenty of energy as glucose in glycogen—in your liver and muscles—to easily live without eating for at least 8–12 hours.  So, there’s no “need” to eat every 3–4 hours.  If there were, we would have gone extinct years ago.  At rest, you’re getting about 60% of your energy supplied by metabolism of fats, not carbohydrates.  Most people can live without all food, but not water, for about two months.

Plenty of people have said, “I’m going to lose weight by just cutting back on food consumption.”  I don’t have scientific data to back it up, but I’d bet that a food diary works better.

A simple weight-loss or management plan that would work better than “just cutting back” would be:

Don’t eat anything man-made

So off limits are bread, rolls, soft drinks, table sugar, high fructose corn syrup, pancakes, pizza, potato chips, Pringles, pies, cookies, cake, casseroles, cannolis, Doritos, Ding-Dongs, Snickers, etc.  I’d complicate it just a bit by avoiding naturally starchy foods like potatoes and corn.

For those who don’t like the negativity of “don’t eat that,” here’s the positive spin:

Eat only natural, minimally processed food

In other words, eat fresh fruit, vegetables, eggs, meat, chicken, fish, olive oil, nuts, etc.  These are God-made foods, not man-made.

Book Review: The New Atkins for a New You

Here’s my review of The New Atkins for  a New You, a weight-loss book by Dr. Eric Westman, Dr. Stephen Phinney, and Dr. Jeff Volek released a week ago.  The copyright holder is Atkins Nutritionals, Inc.  Under Amazon.com’s five-star rating system, I give it four stars (“I like it”).  

♦   ♦   ♦ 

The most exciting nutritional medicine development in recent memory is the fact that saturated fat consumption is not a significant cause of heart disease and premature death. The same goes for for total fat and cholesterol.  When enough physicians, nutritionists, and dietitians learn this, low-carb eating will take off like a rocket.

For those unfamiliar with the Atkins diet, it is designed for weight loss via high fat consumption and major carbohydrate restriction.  Protein intake is a bit higher than average.  As long as carbohydrates (carbs) are kept low, other foods are mostly unlimited.  Atkins has four phases.  As you graduate from one phase tothe next, more carbs are allowed, adding some carb sources before others (the Carb Ladder). 

Atkins has been around for years.  It’s not just a weight-loss diet; it’s a lifetime way of eating.

Doctors Westman, Phinney, and Volek are leaders in low-carb nutritional science.  The last time Atkins peaked (2003), we didn’t have the scientific studies backing up safety of the diet.  Now we do, in large part thanks to these guys. 

Physicians see beaucoup patients with overweight-related medical conditions.  We’re not going to recommend a diet that causes heart attacks, strokes, and other major medical complications.  Published research over the last eight years has established the relative safety of very low-carb diets, particularly Atkins.  Low-carb diets may even be healthier than the low-fat, high-carb diet that has been recommended by U.S. public health authorities for the last forty years.  Come to think of it, our current obesity and diabetes epidemics started around that same time.

The book covers nutrition basics, day-to-day practical application of Atkins eating, recipes and detailed meal plans, and the science behind the program.    

What’s New Since Dr. Atkins’ 2002 Book?

  • adaptations for vegetarians and vegans
  • adaptations for Latinos
  • coffee is now OK
  • introduction of the term “foundation vegetables” and almost doubling the amount of vegetables allowed in Phase 1: “approximately six cups of salad and up to two cups of cooked vegetables, depending upon the ones you select”
  • more flexility, such as the option to skip Phase 1 (induction)
  • focus on adequate protein intake, based on your height
  • emphasis on getting enough omega-3 fatty acids
  • no emphasis on supplements and low-carb products sold by Atkins Nutritionals,Inc.
  • diet journals—a personal record of your weight-loss journey—are recommended
  • eliminate or minimize “induction flu” and constipation (in Phase 1) by eating at least 1/2 teaspoon of salt daily [I’m skeptical.]
  • discussion of the trendy omega-6/omega-3 fatty acid ratio
  • favor monounsaturated fatty acids (e.g., olive oil, canola oil) over certain polyunsaturated fats, as in oils from corn, soybeans, sunflower, cottonseed, and peanuts
  • no mention of testing urine for ketosis
  • more discussion of psychological aspects of weight

The lack of ads for Atkins Nutritionals products is welcome and refreshing.  Too many of the official Atkins books read like infomercials, which diminishes credibility.

A vegetarian or vegan “Atkins diet” is just not something I can visualize.

What Could Have Been Done Better?

  • no specific amounts given for these recommended supplements: calcium, vitamin D, omega-3 fats, multivitamin, magnesium and other minerals (except “no iron”).  [Is the idea to encourage a visit the official Atkins website?]
  • little guidance for physicians who are to advise diabetics doing Atkins.  Few physicians are familiar enough with the program to make the necessary changes in particular diabetic medications.
  • little discussion of the constipation and leg cramps that often accompany very low-carb diets
  • the hype on the cover: “How would you like to LOSE UP TO 15 POUNDS IN TWO WEEKS!”  [To their credit, the authors note that such results are not typical.]
  • nearly all the measurements are U.S. Customary.  Metric users are out of luck.
  • four phases seem a bit much.  The beauty of Atkins Phase 1 is its simplicity. 

My favorite sentence: “White flour is better suited to glue for kindergarten art projects than to nutrition.”

My least favorite sentence: “We can’t stress strongly enough that the best diet for you is one composed of foods you love.”  I love apple pie and Cinnabon cinnamon rolls, but they won’t help me manage my weight.

The only error I found worth mentioning is minor.  The authors state that the American Heart Association recommends consumption of fish three times a week. The official policy is still “at least twice weekly.”

The book is very practical and easily understood by average people.  Most will skip the science chapters at the end.  I know the basic Atkins program works at least short-term; many of my patients have done it.

In summary, the book has nearly everything you need to be successful with the Atkins diet. 

As far as I know, there are no comprehensive long-term studies (e.g., 10+ years) regarding health outcomes of Atkins-style eating.  In other words, does Atkins have any effect on longevity, cancer, heart attacks, strokes, etc.?  But very few of the popular diets have these data either.  The best researched ways of eating in this respect are the Mediterranean diet and vegetarian diets.

Steve Parker, M.D.

Disclosure:  I was given nothing of value for this review by the authors, publisher, or Atkins Nutritionals, Inc.  I wrote it for the benefit of my patients and readers.

Legumes and Cereal Grains: Any Role in Weight Management?

Researchers at the University of Wollongong (Australia) reviewed the scientific literature on the role for cereal grains and legumes in weight management.

In this context, “cereal” refers to “a grass such as wheat, oats, or corn, the starchy grains of which are used as food” (American Heritage Dictionary). 

Here’s their summary:

There is strong evidence that a diet high in whole grains is associated with lower body mass index, smaller waist circumference, and reduced risk of being overweight; that a diet high in whole grains and legumes can help reduce weight gain; and that significant weight loss is achievable with energy-controlled diets that are high in cereals and legumes. There is weak evidence that high intakes of refined grains may cause small increases in waist circumference in women. There is no evidence that low-carbohydrate diets that restrict cereal intakes offer long-term advantages for sustained weight loss. There is insufficient evidence to make clear conclusions about the protective effect of legumes on weight.  

I haven’t read the entire article, but invite you to do so.  I’m searching for clues as to which type of carbs to add after one finishes the Ketogenic Mediterranean Diet.

Low-Carb Killing Spree Continues

The choice is clear . . . NOT

Low-fat and low-carb diets produce equal weight loss and improvements in insulin resistance but the low-carb diet may be detrimental to vascular health, according to a new study in Diabetes.

Methodology

Researchers in the the UK studied 24 obese subjects—15 female and 9 male—randomized to eat either a low-fat (20% fat, 60% carbohydrate) or low-carb (20% carb, 60% fat) diet over 8 weeks.  Average age was 39; average body mass index was 33.6.  Most of them had prediabetes.  Food intake was calculated to result in a 500 calorie per day energy deficit (a reasonable reduced-calorie diet, in other words).  Study participants visited a nutritionist every other day, and all food was provided in exact weighed portions. 

Results

Both groups lost the same amount of weight, about 7.3% of initial body weight. 

Triglycerides dropped by a third in the low-carb group; unchanged in the low-fat cohort.  Changes in total cholesterol, LDL cholesterol, and HDL changes were about the same for both groups.

Systolic blood pressure dropped about 10 points in both groups; diastolic fell by 5 in both.

Aortic augmentation index” fell significantly in the low-fat group and tended to rise in the low-carb group.  According to the researchers, the index is used to estimate systemic arterial stiffness.  [In general, flexible arteries are better for you than stiff ones.  “Hardening-of-the-arteries,” etc.]  The low-fat group started with a AAI of 17, the low-carb group started at 12.  They both ended up in the 13-14 range. 

Peripheral insulin sensitivity improved significantly only in the low-carb group but “there was no significant difference between groups.”  No difference between the groups in hepatic (liver) insulin resistance. 

Fasting insulin levels fell about 20% in the low-fat group and about 40% in the low-carb group, a difference not reaching statistical significance (p=0.17).

The Authors’ Conclusions

This study demonstrates comparable effects on insulin resistance of low-fat and low-carbohydrate diets independent of macronutrient content.  The difference in augmentation index may imply a negative effect of low-carbohydrate diets on vascular risk.

My Comments

Yes, you can indeed lose weight over eight weeks on both low-fat and low-carb diets, if you follow them.  So diets DO work.  No surprise.

Loss of excess body fat by either method lowers your blood pressure.  No surprise.

Once again, concerns about low-carb/high-fat diets adversely affecting common blood lipids—increasing heart disease risk—are not supported.  No surprise

Hyperinsulinemia and insulin resistance are risk factors for development of diabetes and cardiovascular disease.  Results here tend to favor the low-carb diet.  I have to wonder if a study with just twice the number of test subjects would have shown a clear superiority for the low-carb diet.

The authors imply that aortic augmentation index is an important measure in terms of future cardiovascular health.  A major conclusion of this study is that a change in this index with the low-carb diet might adveresly affect heart health.  Yet they don’t bother to discuss this test much at all.  I’m no genius, but neither are the typical readers of Diabetes.  I doubt that they are any more familiar with that index than am I, and I’d never heard of it before. 

[Feel free to educate me regarding aortic augmentation index in the comment section.]

Unfortunately, many readers of this journal article and the associated news releases will come away with the impression, once again, that low-carb diets are bad for your heart. 

I’m not convinced.
