Cut or bulk is the first real nutrition decision every lifter faces, and most people overthink it. The honest answer fits in one sentence: bulk if you're lean, cut if you're not, and recomp only if you're brand new. Here's how to apply that.

How to decide

Men under ~15% body fat / women under ~24%: bulk. You have room to build before fat gain becomes a problem.
Men over ~20% / women over ~30%: cut first. A leaner start makes the eventual bulk more productive and more comfortable.
In between: pick by preference, both work. If you can't decide, cut; it's faster to finish.
First 6 months of lifting: eat at maintenance with high protein and let beginner gains recomp you.

Not sure where you are? Estimate with the body fat calculator.

Setting up a cut

Find your maintenance with the TDEE calculator and eat about 20% under it. Target a loss of 0.5-1% of bodyweight per week. Faster loss burns muscle; slower loss tests your patience. Keep protein at 2.2-2.6 g/kg (the protein calculator does the math) and keep lifting heavy: the weights are what tell your body to keep the muscle.

Cut mistakes

Slashing 1,000+ calories on day one. You lose muscle and rebound.
Replacing lifting with cardio. Lifting keeps muscle; cardio is optional extra burn.
Cutting forever. After 8-16 weeks, take 2-4 weeks at maintenance.

Setting up a bulk

Eat about 10% over TDEE and aim to gain 0.25-0.5% of bodyweight per week, roughly 1-2 kg per month for most men, half that for women. Split the calories with the macro calculator and run a proper progression program like push/pull/legs. A surplus without progressive overload is just a fat-gain protocol.

Bulk mistakes

"Dirty bulking" +1,000 kcal. Muscle is built at ~grams per week; the rest is fat.
Trusting the scale daily. Weigh every morning, judge the weekly average.
Bulking past the point you're comfortable. When you hit ~18-20% (men), wrap it up.

Either way, measure

Both phases live or die on feedback: weekly weight trend, strength numbers, and how you look. Track all three and adjust calories 100-200 at a time. Guessing is how people spend a year "bulking" into a cut they dread.
