Strictly saying 880g of protein. I am not 100kg still.
That is over twice as much as the highest protein consumption I've ever heard of. How can you have any room left in your calorie allowance for carbs or fats?
I urge you to reconsider this diet kyomu. Even if you were heavily juiced, your body won't make use of nearly a kilogram of protein per day.
What's your reasoning behind this diet?
