Even though the diet does provide foods from serval food groups, registered dietitian Toby Amidor R.D. says it's not enough for complete daily nutrition—especially since high-calorie, low-nutrient foods like hot dogs and vanilla ice cream are part of the limited menu. "Due to the lack of adequate amounts of whole grains, vegetables, dairy, and protein, you won't be able to meet your complete nutrient needs over these three days," she explains.

Many studies have focused on diets that reduce calories via a low-carbohydrate (Atkins diet, Scarsdale diet, Zone diet) diet versus a low-fat diet (LEARN diet, Ornish diet). The Nurses' Health Study, an observational cohort study, found that low carbohydrate diets based on vegetable sources of fat and protein are associated with less coronary heart disease. The same study also found no correlation (with multivariate adjustment) between animal fat intake and coronary heart disease (table 4). A long term study that monitored 43,396 Swedish women however suggests that a low carbohydrate-high protein diet, used on a regular basis and without consideration of the nature of carbohydrates or the source of proteins, is associated with increased risk of cardiovascular disease.
When a person goes off the ketogenic diet and regains much of their original weight, it’s often not in the same proportions, says Kizer: Instead of regaining lean muscle, you’re likely to regain fat. “Now you’re back to your starting weight, but you no longer have the muscle mass to burn the calories that you did before,” she says. “That can have lasting effects on your resting metabolic rate, and on your weight long-term.”
If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
I know it's cliché, but let me get specific: When I arrive at a party, I don’t go immediately to the food. I first think about how many hours I plan on being there and try to pace myself accordingly. If I know it’s a three-hour buffet dinner, I may not start eating until an hour into being there. I’ll focus on drinking lots of water first and talk to people, so I don’t stuff my face too early and overdo it.
When I was at my highest weight, I had a full-blown peanut butter addiction. I would eat jars at a time, and my favorite food was Reese’s peanut butter cups. I had absolutely no control of myself when I ate any of it. When I decided that I no longer wanted to be heavy, I made a point to completely stop eating anything with peanuts or peanut butter in it.
