High fat weight loss works- if you can control your protein calories. Patients who don’t lose weight on unlimited, free-feeding low carbohydrate diets, usually get in trouble by eating too much protein. Protein metabolizes to glucose, and eating too much protein creates too much glucose, which causes too much fat storage. If you keep your carbohydrate intake very low, 20 grams per day, 8-10 grams per feeding – the key to weight loss can be not going over-board on protein. Add olive oil to animal protein, and eat higher fat cuts of lamb and beef.. The more fat you eat, the less hungry you will be. The less protein you eat, the fewer sweet and starch cravings you will have, because there will be less circulating glucose. Keep you total calories at no more than 1500-1800 a day, and you’ll melt.
