Women assigned to diet-plus-exercise, who exercised less than 22 minutes per day, 7 days per week (less than 154 minutes per week) lost an average of 9.6% after one year, losing an average of 17.6 lbs, dropping from roughly 183 lbs down to 165 lbs according to a recent study from the U.S.

Women assigned to diet-plus-exercise, who exercised 22 to 28 minutes per day, 7 days per week (154 to 196 minutes per week) lost an average of 12.7% after one year, losing an average of 23.1 lbs, dropping from roughly 182 lbs down to 159 lbs according to a recent study from the U.S.

Women assigned to diet-plus-exercise, who exercised 28 minutes per day or more, 7 days per week (196 minutes per week or more) lost an average of 12.9% after one year, losing an average of 23.1 lbs, dropping from roughly 180 lbs down to 157 lbs according to a recent study from the U.S.

People assigned to eat diets with a different composition of protein (15% vs 25%), fat (20% vs 40%) and carbohydrates (35% to 65%), but the same number of calories, lost the same amount of weight and same amount of fat according to a recent study from researchers at Harvard University. The average weight loss was 13.9 lbs after six months which was similar in all the diet groups, with 9.2 lbs coming from body fat, and 4.6 lbs coming from lean body mass (muscle) “with no differences between 25% and 15% protein, 40% and 20% fat, or 65% and 35% carbohydrate.”

“Advice to eat low-fat diets, especially low in saturated fat and cholesterol… has no basis whatever,” writes Joel M. Kauffman, PhD, the author of Malignant Medical Myths: Why Medical Treatment Causes 200,000 Deaths in the USA each Year, and How to Protect Yourself.

People assigned to eat a low-calorie diet of 1000-1200 calories per day lost nearly twice as much weight loss as those assigned to limit their fat intake to 22-26 grams per day according to a 1999 study by Jean Harvey-Berino from the University of Vermont.

Those assigned to the low-caloried diet lost an average of 24.6 lbs after six months versus 13.4 lbs for those assigned to the fat-restricted diet.

People assigned to eat a low-calorie diet of 1000-1200 calories per day lost nearly twice as much weight loss after six months as those assigned to limit their fat intake to 22-26 grams per day—24.6 lbs vs 13.4 lbs—and also maintained a much greater weight loss after 18 months—16.5 lbs vs 4 lbs—according to a 1999 study by Jean Harvey-Berino from the University of Vermont.

A high-protein, reduced-fat diet causes more weight loss and more belly fat loss than a moderate-protein reduced-fat diet according to the always interesting research group from Denmark which includes Arnie Astrup and S. Toubro.

People lost twice as much weight after three months and six months on a high-protein, low-carb diet than a low-fat, high-carbohydrate diet, but the difference in weight loss was not significantly different after one year according to the first randomized, controlled trial of a low-carb diet that was published in The New England Journal of Medicine.

“Participants on a low-carbohydrate diet had more favorable overall outcomes at one-year than did those on a conventional [low-fat] diet,” concludes a new study conducted at the Philadelphia Veterans Affairs Medical Center. People who were assigned to follow a low-carb diet maintained a weight loss of 11.2 pounds after one-year compared to a weight loss of 6.8 pounds for people who were assigned to follow a low-fat diet. The difference in weight loss between the groups was not statistically significant, however there still was an 80 percent chance that this difference in weight loss was due to the diet. Some articles have concluded that this study shows that low-carb diets are no better than low-fat diets, however this was not the conclusion of the study.

Women lose twice as much weight—18.7 lbs vs 8.6 lbs—and twice as much body fat—10.6 lbs vs 4.4 lbs—on a low-carbohydrate diet as a low-fat diet according to a recent study.

Patients eating a low-carbohydrate group lost nearly twice as much weight as those in the low-fat group. Those in the low-carb group lost an average of 26.4 pounds versus 14.3 pounds for those in the low-fat group.

Twenty native Hawaiians lost an average of 17.2 pounds in three weeks or 6.4 percent of their body weight by following a traditional Hawaiian diet according to a 1991 study (Shintani et al, 1991).

A 10 percent reduction in dietary fat causes obese people to lose an average of roughly 11 pounds according to a recent paper.

A high-soy-protein, low-fat diet causes more weight loss than lifestyle education according to a study from Germany.

Low fat diets cause an average weight loss of 5.5 pounds according to a recent review by Arnie Astrup of sixteen low-fat studies.

Patients who underwent laparoscopic gastric bypass weight loss surgery lost a similar amount of weight whether they were following a low-carbohydrate, high-protein diet or a low-fat, high-carbohydrate diet according to a new study from researchers at the University of Virginia Health System in Charlottesville, Virginia, USA.

Women following an “Atkins diet for a year not only lost more weight than the [women following The Zone diet, a low-fat diet or a balanced diet], but also experienced the most benefits in terms of cholesterol and blood pressure,” according to a year-long study from Stanford University published in the March 7th, 2007 issue of the Journal of the American Medical Association.

Women on a low-carbohydrate Atkin’s diet lost roughly 10 lbs after one year vs 4-6 lbs for those on three other diets.

Women on a low carbohydrate lost an additional 7 pounds of body weight and 12 pounds of body fat in four months compared to women on a low calorie, low fat diet according to a recent study.

Men lose roughly 1.5 times more weight (22 lbs vs 14.5 lbs) and nearly twice as much fat (18 lbs vs 10 lbs) with a low-carb diet versus a high-carb diet according to a study from Australia.
