U would be surprized at how fast your body can get depleted. I would highly reccomend for anyone doing a meat fast to make sure they take their vitamins. For a list of mine U can check under the post cause "what supplements is everyone taking" in general low carber. And be careful too, how long U do the meat fast tony...Im wondering if U go too long...how it will effect U once U add carbs back? Will your body then decide "oh ok we had 20 grams today guess we should put on some weight?" Im not sure, dont have the answer but it is something to think about.
