Cutting Macros for a 130 lb Male (Carnivore)

A practical starting target is 1872 calories/day — a 464-calorie deficit below your estimated TDEE of 2336. This provides a meaningful signal for fat loss without being aggressive enough to risk significant muscle loss or excessive fat gain. Adjust in 100-calorie steps after 2–3 weeks of data.

At 130 lb, a daily target of 130gm of protein (1.00g per lb bodyweight) supports body composition goals whether cutting, building, or maintaining. Protein has a higher thermic effect than carbs or fats, keeps hunger lower than either, and directly determines how much muscle your body can build or retain. Distribute across 3–5 meals for best use — a single large protein serving has diminishing returns compared to spread intake.

Muscle loss risk on a 464-calorie deficit is real but manageable. The most important protection is keeping protein at 130gm/day — elevated protein directly reduces muscle breakdown during a deficit. Continuing resistance training is the second most important factor; muscle is only retained if it is being used. A 464-calorie deficit is in a moderate range, which means weekly fat loss should be around 0.1 lbs — sustainable without requiring the body to cannibalize significant lean tissue.

At 1872 calories, a carnivore day for a 130 lb man is built entirely from animal protein and fat: fatty cuts of beef, eggs, butter, chicken thighs, salmon, or pork belly are typical staples. The target is 130gm protein and 148gm fat with 5gm carbs (trace amounts from eggs or some dairy). Ribeye steak is the closest single-food option to a complete carnivore macro profile. Most people find 2–3 meals per day easier to sustain than 4+ on carnivore.

At 130 lb, total calorie targets are lower, which means every macro gram matters more. Protein is the priority to protect — at 130gm, you are targeting 1.00g per lb, which leaves little room to reduce protein without consequences for muscle retention. If you need to reduce total calories, trim from carbs or fats, not protein. The lower absolute calorie target also means tracking accuracy is more important: a 200-calorie tracking error represents a larger percentage of total intake at 1872 calories than it would at 2,800+.
