Structure is the key to losing weight, because if you just freely feed on protein and fat – the bet is you won’t decrease your calories enough to lose weight fast enough, to make it worth your while to keep on dieting. I like to see a 4-5 pound weight loss every week, because this kind of weight loss is very motivating and keeps you dieting. You can squeak by losing 2-3 pounds a week, but it’s harder to keep your motivation up with slower weight loss. To lose weight as fast as possible, you have to eat as little as possible – and most patients do better with 1-2 meals a day. Frequent small feedings (4-6 meals a day) helps some patients lose weight, but most people do much better eating just 1-2 meals a day. Keep your calories under 1500 a day, ideally under 1000 a day. Keep your carbohydrate intake to 5-10 grams per feeding.
