I should mention I was 275lbs, I'm now down to 228lbs. I plan on being 170lbs and pretty muscular by next year. :) I'll be 40 in September. I hope to be under 200 by my 40th birthday and in great shape by 41. I want the last half of my life to be pain free and healthy for as long as possible.
If you have no weight to lose, don't worry. When fasting, your body will adjust naturally. But you do have to survive the 5 days, the mimicking diet will help with that. If you're getting 40g of protein mostly from plant sources per day, you have nothing to worry about. That's 2 vegansmart drinks a day, with fruits and vegetables on top of that. It makes getting through the day a JOOOOKE!
I plan on getting new blood tests done to see how much I have reduced the CRP and RF in comparison to when I was very bad just over 2 months ago to share the progress with you.
