Energy balance

Natural bodybuilders in the off-season should consume a hyper-energetic diet (~10–20% above maintenance) targeting a weight gain of 0.25–0.5% of bodyweight per week, with advanced lifters using a more conservative surplus to minimize fat gain.

Calculate your maintenance calories. Add 10-20% if you are new to lifting, or 5-10% if you are advanced. Weigh yourself daily and average it weekly. If you gain more than 0.5% of your body weight, reduce calories slightly. If you gain less, increase them slightly. This prevents excessive fat gain while supporting muscle growth.

ModerateQualifiesMEDIUM confidence
Based on the current evidence, it may be appropriate to recommend bodybuilders to consume a slightly hyper-energetic diet (~10–20% above maintenance calories) in the off-season and recommend advanced bodybuilders to aim for the lower end of this recommendation... Aiming for a target weight gain of ~0.25–0.5% of bodyweight per week might be useful

Why this rating

The recommendation is based on a narrative review of observational data and extrapolated studies on trained vs. untrained subjects, lacking direct RCTs on elite bodybuilders.
