Hi All,

Brand new to this diet, have a “mammoth” task ahead of me as I am a male, 40 year old and around 400 pounds! Don’t normally admit that to anyone.

I understand the basic principle of the plan and have the book to read but just want to make sure I am understanding correctly.

As I am so large I thought it may not be sensible to do the fast at 600 cals? so I used the calculator to give me a tdee which is 3350 now to me that sounds far too much for a normal day? basing the fast day on the quarter this would then give me a little over 800 cals on a fast day, but my understanding is that 600 is the upper limit on fast days is that correct or should I go closer to the 800 because of my size?

My last question is how often should I recalculate the allowance if I start at a higher ammount should I do it after half a stone or a stone of loss? or weekly?

Thanks for any advice
