Will I Gain Weight If I Eat My TDEE?

Will I gain weight if I eat my TDEE? This is a common concern for people trying to understand whether maintenance calories truly keep weight stable over time.

Eating around your calculated TDEE should maintain your weight over time, not cause consistent gain, assuming the estimate and logging are accurate. However, TDEE is still an estimate, and activity or tracking errors can mean you eat slightly above your true maintenance. If you notice a steady upward trend in weekly average weight, your real TDEE is likely lower than the calculator predicted, or you are underestimating intake. In that case, reduce calories by 5–10% or increase daily movement and reassess after two to three weeks. Short-term fluctuations from water, hormones, or sodium are normal; focus on multi‑week averages rather than day‑to‑day changes when judging whether you are gaining.
