Macro partitioning
Consuming casein protein (~30-40 g) before sleep increases muscle protein synthesis and metabolic rate overnight without affecting lipolysis.
If you want to support muscle growth overnight, have 30-40 grams of casein protein (like cottage cheese or a casein shake) right before bed.
GoodSupportsMEDIUM confidence
Consuming casein protein (~ 30–40 g) prior to sleep can acutely increase MPS and metabolic rate throughout the night without influencing lipolysis.
Why this rating
Position stand recommendation, but specific to casein and sleep timing.

- Post-exercise ingestion of high-quality protein (20–40 g) within 2 hours maximally stimulates muscle protein synthesis and supports strength and body composition improvements.Strong
- For rapid glycogen restoration (<4h recovery), aggressive carbohydrate refeeding (1.2 g/kg/h) with high glycemic index sources, optionally combined with protein (0.2-0.4 g/kg/h) or caffeine, is recommended.Strong
- Consuming 30-60 g of carbohydrate per hour during endurance exercise lasting >70 minutes improves performance and maintains blood glucose.Strong

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
