Question

An individual consumes an extra 300 kcal/day from fat compared to their usual energy needs. Evaluate the approximate monthly weight gain attributable to that surplus, assuming 1 lb body fat ≈ 3500 kcal. Show your reasoning.

Accepted Answer

Approximately 2.57 pounds gained in a month (9,000 kcal surplus ÷ 3,500 kcal/lb ≈ 2.57 lb); this is the best estimate.

Answer

Exactly 1 pound per month because the body always converts 3,000 kcal into 1 lb of fat regardless of macronutrient source.

Answer

Approximately 0.86 pounds in a month because fat is stored inefficiently and most excess dietary fat is excreted.

Answer

No weight gain will occur because adipose tissue cannot expand after early adulthood and excess calories are directed to muscle hypertrophy only.
