Bodybuilding nutrition comes down to three controllable things: enough protein spread across the day, an energy intake deliberately matched to the phase you are in, and enough consistency for those to matter over months. Research supports roughly 1.4–2.0 g of protein per kilogram of body weight per day for exercising people, with pooled resistance-training data showing benefits levelling off near 1.6 g/kg/day. Prepared, macro-labelled meals help most with the part people fail at — repeating the same adequate meals for weeks without decision fatigue.

Hypertrophy-focused training is high-volume resistance work targeting muscle groups across a weekly split, usually four to six sessions. The training stimulus is only half the equation; the other half is providing enough protein and energy for tissue to be built and retained.
The phases differ sharply. A building phase runs a modest energy surplus; a cutting phase runs a deficit while trying to preserve muscle, which is where protein intake and training quality become protective rather than optional.
The ISSN position stand concludes that resistance exercise and protein intake both stimulate muscle protein synthesis and that roughly 1.4–2.0 g/kg/day is sufficient for most exercising people.
Morton and colleagues' meta-analysis found that supplemental protein improves gains in strength and lean mass with resistance training, with the pooled effect plateauing around 1.6 g/kg/day. Some physique athletes in a deficit choose to sit above that range; the evidence for extra benefit beyond it is limited.
Carbohydrate supports training quality, which matters most in a deficit — the consensus literature on carbohydrate availability is relevant here for high-volume sessions.
How strong is this evidence? This page will not provide extreme cutting protocols, dehydration or peak-week manipulation guidance. Those practices carry real health risks and belong with a qualified coach and clinician. If food, weight or body image is causing distress, please talk to a healthcare professional.

Our dedicated 100% gluten-free kitchen means the full menu is available to lifters with coeliac disease or gluten sensitivity. To be clear: gluten-free is not an anabolic or fat-loss strategy in itself, and any physique change comes from training and energy balance, not from removing gluten.
