I've been eating No Sugar, No Grain for several years (no potatoes either). And I had hit a plateau. Still had about 30-40 lbs to lose to be where I wanted to be. (the weight is a guestimate cuz I dont really give a damn about weight, i care about how my cloths fit and that my love handles aren't obvious) I seemed to be stuck so I went and talked to a trainer I know (he's a little salty) and he sent me to the Doc that is working on a new eating plan for the American Diabetic Association. The new diet is basically No grain, no sugar but they also add a 'fat fast' which is 1000 to 1500 calories for 2 weeks at 80 to 90% fat. He told me the mistake I was making was too much protein and not enough fat in my diet. two weeks later im down 8 lbs. Its harder than it sounds to eat 80-90% fat on 1000 to 1500 calories. The key is keeping calorie intake low and eating primarily fat which puts you into ketogenisus (sp?). I'm in maintenance mode for another 2 weeks, back to no grain no sugar and 1500-2000 calories. . This certainly got me over the plateau and the good news is.... you dont feel hungry and the cooking is super easy. 4-6, 250 calorie feedings a day. SAMPLE MENU Breakfast: Coffee, heavy cream (or real coconut milk) and butter Snack: Cashews Lunch: any meat with bacon, celery with oil and vinegar or some other veggie Snack: chocolate fat bomb (will post recipe if anyone is interested) Dinner: sriracha tacos in cabbage leaves The 1st 2 days i didn't eat after 6pm and i had coffee with cream and butter for breakfast and snack. Apparently this 18 hour semi fast for 18 hours puts you in to ketosis faster. Food and diet are weird. I guess because 1) everyone is different 2) we have been lied to by the food and drug industry who did things to sell stuff not for human betterment. (remember cholesterol and eggs? biggest lie ever told as there is no proven direct relationship between dietary cholesterol and high cholesterol in the body and it ruined the egg industry for years) This type of 'fasting' isnt for everyone. I had to be super careful/strick with my carbs. Somedays I had less than 10 grams and other days as much as 50 grams. But it certainly worked for getting my past a plateau.
