Is consuming more protein at night better if protein during the day is beneficial? A recent study debunks this theory, stating that an additional protein intake before sleep doesn’t enhance recovery, performance, or muscle gain.
The Pre-Bed Protein Boost Theory
Due to the fasting period during sleep, some experts theorize that a pre-bed protein boost could enhance your condition the next day. To test this theory, scientists conducted an experiment with over 100 British army recruits during basic training. The recruits were divided into four groups: high protein before bed (60 grams), low protein before bed (20 grams), carbs before bed, or no meal at all.
The Impact of Additional Protein Intake
Despite the additional protein intake, all four groups experienced similar changes in fat mass, bone mineral density, exercise performance, recovery, muscle soreness, and the perception of fatigue.
Understanding Protein Thresholds
Why didn’t additional protein make a difference? The answer lies in the protein threshold. The participants were likely already consuming enough protein. From a muscle and performance perspective, there’s a certain threshold you need to reach for protein to be effective.
Optimal Protein Intake for Muscle Building and Recovery
Consuming about 1.6g/kg per day of your body weight is sufficient to help build muscle, train hard, and improve recovery. Consuming more than this amount doesn’t result in significant additional changes.
| Bodyweight (lb) | Bodyweight (kg) | Daily Protein When Training |
| 200 lb | 91 kg | 145 g per day |
| 190 lb | 86 kg | 138 g per day |
| 180 lb | 81 kg | 131 g per day |
| 170 lb | 77 kg | 124 g per day |
| 160 lb | 72 kg | 116 g per day |
| 150 lb | 68 kg | 109 g per day |
The Importance of Meeting Minimum Protein Requirements
While consuming more protein may offer some benefits, it’s more crucial to meet the minimum protein requirements than to consume the maximum amount.
Key Takeaway: Focus on Total Daily Protein Intake
To maximize the benefits of your diet, focus on consuming enough total protein throughout the day rather than worrying about when you consume it. There’s no need to take protein before you sleep, but there’s likely little downside if you do.
