IF and Low Carb... Perfect!!

I have been on Fast 5 since March. My diet reflects a Pritikin style of eating with an emphasis on whole grains, vegetables and fruits consistent with your recommendation (Ronny Andersen's). I have also been working out on a Concept 2 rowing machine. Weight loss has been slow, but steady (I am half way to my goal of losing 80 pounds), and, so far, I see no evidence of weakness due to muscle loss. Maybe low carb works for some people, but I am skeptical about the long-term consequences. I can attest to the fact that you can succeed with a more balanced approach incorporating lots of unrefined foods full of starches (whole wheat, potatoes, squash, brown rice, beans......).

your body only runs on glucose if you eat carbs

This is all completely false. Did you read the ebook at all? Lots of good information about glucose, ketone production, what our bodies use for energy in the absence of glucose, etc.

I do not agree that the body runs on glucose. It runs on fat. Fat must also be the main energy for the body. The brain does use some glucose, but not much ( only 4 gms of glucose is circulating in the body) and indeed it can make it out of proteine but this not make the body acidic. The body does not need much protein; only when your body is wasted you need to eat about 100 gms a day. You will gain some weigh because mussles are havier than fat. After that you must cut your protein down to sufficient amount.
Nitrientfat does not lead to body fat. Body fat comes from sugars (carbs). Because sugar is a poison, the body wants to get rid of it by burning is first before other nutrients. It can not do this fast enough so the body stores is, savely) as body fat. But if your are not custom to burn fat for energy, it stays on your body. So you must teach your body to burn this stored fat. You do this by not eating any sugars. How do I know that my body is burning my body fat? I am not hungry for a long time. If you eat sugars, you are hungry all the time because of partially storing the 'food' into your body as fat instead of using it for energy. Sugar needs lots of protein, vitamins and minerals to metabolise. You don't want to waste your nutrients, so don't eat sugars. Whole grains are as bad as refined.
