>>76376875 (OP)Why do you think bodybuilders start their cut 6 months BEFORE competition, making no gains but just plan on maintaining?
Even if you run a daily deficit of 770kcal a day, that would be 23100kcal a month or 3kg a month.
Losing 15kg of fat this way would take 5 months, 152 days to be exact.
Why do you think most people aren't lean, why do you think most gym goers aren't shredded? Because it's fucking hard and miserable as fuck and you MAKE NO GAINS DURING THAT TIME.
