In BFFM, you write “Reduce your calories by 15-20% below maintenance for optimal, safe fat loss,” and note that 30% is a high deficit tahat can be used when zig zagging with high calorie days. So, while the BFFM guidelines certainly range from 15-30%, I was wondering if there has been a change in thought about the optimal deficit for safe fat loss. I ask because the more recent Bodyfat Solution, I think, also uses a slightly higher deficit range then the BFFM quote above suggests. I’ve been sticking with 15-20 and am losing my pound a week with slight LBM loss over a four week period. I dont think I would do better by increasing the deficit under these circumstances (and know you don’t suggest that for my results).
