Whey Protein and Fasting
Last week I fasted three days on water. It was challenging but I wanted to do it and am very pleased with myself for doing it. I lost about 8 kilos, going down from 87 kilos to 78 1/2. I am slender in body form but over the years have managed to build up a lot of stubborn body fat around my waist. Although I exercise regularly the fat in this area did not diminish until the fast. My goal is NOT to reduce the fat in this area but to get RID of it altogether.
So, I am water-fasting this weekend as well. As a matter of fact I have been looking forward to it. I have prepared myself by eating only fruits today (Friday, 18-06-10). After 18:00 this evening I will not eat again until Sunday 18:00.
My only concern is that last week when I water-fasted I lost a lot of muscle size. I considered taking whey protein this time but have decided against it for two reasons. One, the duration of the fast is only for 48 hours and taking whey protein might subtract from the benefits I am to receive from fasting; two, I’ve been informed that the body will use protein as fuel when its supply of fuel from food is not available.
If my information is correct the reason that I lost muscle size in my last fast was because my body started taking protein from my muscles in order to use it as an energy source. Obviously I don’t want my body using whey protein as an energy source, rather, I want it to use the accumulated fat around my waistline.

You did not lose muscle mass during a two day fast. You did lose water. When you go to the gym your muscles pump up. A few hours later or a day later the muscles reduce in mass. They are just as strong but they have less fluid. Fat has 3600 calories per pound that is easy to break down and is designed as a energy storage so why would your body use valuable muscle tissue that only has 1817 calories per pound and is hard to break down. Your body also has reduced salt levels and that reduces cellular water retention.
A high quality whey supplement is good during juice fasting if you want to train hard and get cut. During water fasting it defeats the purpose. You are living on pure protein and that does not seem like a good plan to me. I did a fast on egg white with 4 hour of hard training a day. Wow was I cut after 20 days. Whey will do the same. You will not have the mass but you do get cut. (muscle definition)
