I have a friend who went from:
8% - 13% over a couple of months
13% - 8% in about 6 weeks.
However his natural bf% (no specific diet or training regime) was 8% from his teenage years until he pigged out.
At 13% he was a slob, ate fast food multiple times a day, didn't exercise, drank 400ml vodka and a litre of beer two nights a week.
He dropped the weight lifting+cardio+clean eating (not counting cals or anything)
Now he has dropped his diet except for eating enough protein, eats fast food and drinks the same alcohol but he has kept his gym routine and managed to maintain the lean 8% (still has very visible 6 pack).
What I am asking is, do our bodies adjust to a bf% once we get there or are they trying to bounce back to our natural bf% state ?
I able to get away with anything he does at my 14% vs his 8% although I carry much more muscle.
At 14% I can eat kfc, pizza, chinese food etc as long as I get enough protein I don't get fat gain weight, That was my diet plan for 9 months, just get enough protein through whey and have 1-2 large 1500 cal meals and I gained a bunch of muscle and no fat.
If I drop to 8% will I be able to live the same way, or is my body cursed to bounce back to 14%. But my friend can get away with slacking since he is naturally 8-10% since his early teens ?
