## Why TDEE matters for bulking



Muscle gain needs enough calories to support training and recovery. Too small of a surplus can make progress slow; too large of a surplus often adds unnecessary fat.

TDEE is the estimated maintenance line. A lean bulk usually starts modestly above that line, then adjusts based on strength, body weight trend, and visual changes.
## Choosing the right surplus



A lean surplus is best when you want slower weight gain and less fat gain. A moderate surplus fits many lifters who want performance and visible progress. An aggressive surplus is usually better for hardgainers or short phases where extra fat gain is acceptable.

If you are already gaining weight faster than planned, reduce calories. If weight and gym performance are flat for several weeks, increase slightly.
## Macros for muscle gain



Protein should be high enough to support muscle repair, but more is not always better once the target is met. Carbs often help training volume, while fats support food preference and calorie density.

Calorieo helps you log repeat meals, protein foods, shakes, restaurant meals, and snacks so the surplus is intentional instead of accidental.
## FAQ

### How many calories above TDEE should I eat to bulk?

Many lifters start around 150 to 350 calories above TDEE for a lean bulk. Hardgainers may need more, but adjust based on weekly weight trends.

### How fast should I gain weight while bulking?

A common lean-bulk target is roughly 0.25 to 0.5 percent of body weight per week. Faster can work, but often increases fat gain.

### Can I use this for bodybuilding?

Yes. It is a practical starting point for muscle gain, but advanced athletes may want coach-specific macros and tighter tracking.
