Doctor, How Do YOU Stay Thin? My Not-So-Secret Revealed...
"But Dr. Grimes, YOU don't have to worry about YOUR weight- you're tiny! You don't know what it is like to struggle with your weight."
Every time I hear this from a patient, I am not sure if I should laugh or cry. While yes, there are some people out there who seem to be able to eat whatever they want and never exercise, and yet stay thin, healthy, gorgeous, rich and let's throw in perfect in every way (ha!), MOST people who appear healthy make very conscious choices to keep themselves there. As my close friends can attest, I love to eat delicious foods of all categories- nutritious or not.
Unfortunately, after having an exceptionally active metabolism up until age 25, I am now (& have been for over two decades) fully capable of packing on the pounds with the best of them. In my first pregnancy, despite delivering a month early and enduring over seven months of morning sickness that lasted day and night, I was mortified to gain forty pounds. I'm sure eating nonstop pizza & burgers (because nothing else appealed to me) might have had something to do with that...but I digress. The point is that if I do not keep a close eye on my weight, I gain more than I would like. I can lay the blame wherever I would like- blame medications, injuries, stress, or whatever- but that doesn't change the end result. If I gain weight, I have to lose it the same way everyone else does, by burning more calories than I consume. So what exactly do I do?
1. RECOGNIZE THE PROBLEM- I try to weigh every morning, aware that everyone has a natural up and down flux of a couple pounds. When I hit 3 pounds higher than my average, that's my ceiling and it's time to get serious before it gets out of hand. (This may be the most important step. When I skip this step, it's 5-10 pounds up, which is much tougher!)
2. START WITH A SEVERAL DAY "CLEANSE"- I'm not talking about an enema here! I simply go back to basics and eat ONLY fruits, veggies, and a simple protein (nuts, beans, fish, chicken or lean meat.) I also drink as much water as I can stand (about 6 glasses in a day), and no other beverages. The picture above is my lunch- large portioned, delicious and 90% veggies.
3. RAMP UP MY EXERCISE- for the record, I walk our dogs around two miles per day every day. This is both for the dogs & for me to MAINTAIN my weight. If I need to lose, this is not enough, because this is my baseline- I need "MORE". I typically add in a second walk or get on the exercise bike for 30 minutes in addition to the daily walk.
4. TRY TO HAVE REALISTIC EXPECTATIONS- good weight loss is 1/2-1 pound per week. I am as guilty as the next person that after two days of being "perfect", I am disappointed when my weight has not miraculously jumped back two or three pounds to baseline. By the end of a week (Mon-Friday) I have typically seen the scale budge at least a half pound, and once I know I am headed back in the right direction, I start to loosen up the diet by allowing some processed foods back in, but at restricted portions. Truth be told, I let in dessert first- but make healthy choices such as some whip cream on strawberries or chocolate syrup on a banana. Next I might bring back corn chips (I'm gluten-free, so less likely to choose cereal, breads, or crackers). I very slowly add in other foods until I am back to my healthy baseline, which includes some high calorie treats ONCE I am back where I want to be.
BOTTOM LINE: Virtually EVERYONE needs to be conscious about their weight and health choices for nutrition and exercise- don't assume thin people are just "lucky".

Which Diet is Best for Weight Loss?
Now there is the million dollar question, right? Interestingly, despite billions of health care dollars being spent on "diets", there are not recent high level studies in the medical literature to support touting one weight loss diet highly above all the rest. In 2001, there was a scientific review of popular diets by Freedman, King, & Kennedy, that concluded "low fat, low calorie diets are the most successful in maintaining weight loss." Note- this is in MAINTAINING weight loss, not LOSING weight. Ultimately, as should come as little or no surprise, CALORIC BALANCE is the major determinant of weight loss, regardless of the composition.
So...which diet? HIGH protein, LOW carb diets have a very high satiety effect- you are simply not as HUNGRY when you restrict calories if there is a high protein content. Several studies have demonstrated that the less hungry (more satiated) people are, the higher their compliance rate with a calorie restricted diet. This sounds rather obvious- if you are not hungry, you won't "cheat"- BUT...remember most of us do not eat because we are hungry. We eat because we are happy, sad, mad, bored, distracted- you name it. (See related post "Break the Eat, Repent, Repeat Cycle").
Are high protein diets safe for the kidneys? A 2012 study at the Indiana School of Medicine confirmed that low carb, high protein diets do NOT cause any harm to the kidney function in obese patients who had healthy kidneys at the start.
What about the heart? A very large study this year in Sweeden (>40,000 women) did show that women do develop an increased risk of cardiovascular disease (heart attacks & stroke) if they stay on a low carb/ high protein diet long-term. However, in the short term (at one year), low carb/high protein diets are more effective in weight loss and reducing cardiovascular disease risk.
BOTTOM LINE: Low carb/ high protein diets may help you lose weight in the short term (~ a year), but for long-term weight maintenance or continued weight loss, go for what you know to be healthy- MORE fruits & vegetables & a lean protein source.
