In an analysis of data from nearly 50 trials (7,300 people) significant weight loss was observed with any low-carbohydrate or low-fat diet, with weight loss differences between diet programs small, so small as to be insignificant. That's "any" low-carb or "any" low-fat diet. Any. Just pick one you think you can stick to and live with. In other words, whatever works!
When people hear the word "diet," most think of calorie restriction, deprivation, making up for past indulgences, and as so forth. There is something unpleasant, almost punitive about the whole concept of dieting, which is unfortunate because it can make it harder to turn to healthier eating regimens.
