For general strength training, three things carry almost all the weight: enough protein spread across the day, enough total energy to support your training and your goal, and enough carbohydrate to get through higher-volume sessions without falling apart. Research places sufficient protein for most exercising people at roughly 1.4–2.0 g per kilogram of body weight per day, and pooled analyses of resistance-training studies show the benefit of extra protein levelling off around 1.6 g/kg/day. More is not endlessly better.
A strength session is a series of hard, brief efforts with long rests. The session itself does not burn enormous energy, but the adaptation it triggers — repairing and building muscle tissue, restoring glycogen, tolerating accumulating fatigue across a training block — is what your eating has to support.
Training volume, not the fact of lifting, is what drives carbohydrate needs. A three-exercise strength day of heavy triples is not the same as a high-volume hypertrophy session with 25 hard sets.
Muscle protein synthesis is elevated for many hours after training, which is why daily protein matters more than any single post-workout window.
Chronically low energy intake blunts progress regardless of how good the protein number looks.
Higher-volume blocks lean more on muscle glycogen; heavy low-rep work leans on it less.
Sleep and consistency beat any supplement in this category.
What the evidence says
The ISSN position stand on protein and exercise concludes that both resistance exercise and protein ingestion stimulate muscle protein synthesis, and that around 1.4–2.0 g/kg/day is sufficient for most exercising individuals.
Morton and colleagues' meta-analysis of protein supplementation with resistance training found that added protein improves gains in strength and lean mass, with the pooled effect plateauing at roughly 1.6 g/kg/day. That is the strongest single argument against the idea that doubling your protein doubles your results.
Where training volume rises, carbohydrate availability principles from the endurance consensus literature start to be relevant to how a long session feels.
How strong is this evidence? These are population averages from pooled research. Individual responses vary, particularly for older lifters, people in an energy deficit, and anyone with a medical condition affecting protein or carbohydrate handling.
A mixed meal with protein and carbohydrate two to three hours out covers most people.
Training early? A smaller carbohydrate-containing snack is usually enough; training fasted is fine if it suits you.
After training
A protein-containing meal within a few hours. The old 'anabolic window' panic was overstated — daily totals and distribution matter more.
Include carbohydrate, especially after high-volume work or if you train again tomorrow.
Rest days
Keep protein the same. This is the single most common mistake — protein needs do not take the day off.
Carbohydrate can come down a little if fat loss is the goal.

An example lifting day
Training day
Breakfast: protein plus carbohydrate.
Lunch (pre-training): a mixed meal two to three hours before lifting.
Post-training: a protein-forward bowl with rice.
Evening: protein, vegetables and a starch sized to the day.
Rest day
Same protein at each meal; slightly less carbohydrate; more vegetables.
An example framework, not a prescription. Body weight and training volume change the numbers.
Where gluten-free actually fits
Our kitchen is dedicated 100% gluten-free, so lifters with coeliac disease or gluten sensitivity can order the whole menu without cross-contamination worries. For everyone else: gluten-free is not an anabolic strategy. It does not add strength, reduce soreness or improve recovery on its own.
Frequently asked questions
How much protein should I eat for strength training?
Research in exercising populations supports roughly 1.4–2.0 g per kilogram of body weight per day, with resistance-training benefits levelling off near 1.6 g/kg/day in pooled analyses. Spreading it across three to five meals is a reasonable practical approach.
Do I need a post-workout shake?
No. A protein-containing meal within a few hours does the same job. Shakes are convenience, not magic.
Should I eat carbs if I am trying to lose fat while lifting?
Usually yes, at least some. Carbohydrate supports training quality, and training quality is what preserves muscle in a deficit. How much depends on your size, deficit and volume, which is a good question for a dietitian.
Do prepared meals work for a lifting diet?
They work well for the repetitive part — hitting protein at lunch and dinner without cooking daily. Macros are published for each meal, so you can plan around them rather than guessing.
