Swapping protein calories for fat calories is really worth a try, especially if you absolutely, positively cannot stay on a low carb diet. You may surprise yourself. An easy way to test this is with Lean Cuisine or Healthy Choice or Healthy Steamers. Figure 300 calories per package, and about half of them from protein and vegies. One day, eat 6 packages, pitching the carbohydrate – pitch the noodles, rice, pasta, potatoes, stuffing, etc. The next day, eat 3 packages, pitching the carbohydrate, but add a tablespoon and a half of olive oil or butter to each package. You are eating the same 900-1000 calories each day. You can eat 1, 2 or 3 meals. It makes no difference. What will likely make the difference is the fat. See how you feel each day. See which diet makes you less hungry. See which diet is more satisfying. Eating less protein on your 3 package day, will also likely create fewer sweet and starch cravings, as protein raises blood glucose, in a way that fat does not.
