Protein Myths Debunked

Protein is the most discussed, most debated, and most misunderstood macronutrient. Let's clear up the biggest myths that are probably holding you back.

Myth: Your body can only absorb 30g of protein per meal. This is nonsense. Your body will absorb whatever you give it — it just takes longer with larger amounts. Studies show muscle protein synthesis is optimised at 0.4-0.55g/kg per meal, which for most people is 30-50g, but your body doesn't waste the rest.

Myth: High protein diets damage your kidneys. In healthy individuals, there is zero evidence that protein intakes up to 2.2g/kg bodyweight cause kidney damage. This myth originated from dietary recommendations for people with pre-existing kidney disease.

Myth: You need protein immediately after training. The post-workout 'anabolic window' is real but it's more like a 'barn door' than a window. As long as you consume adequate protein within a few hours either side of training, you'll maximise muscle protein synthesis.

Myth: Plant protein is inferior to animal protein. Individual plant sources have incomplete amino acid profiles, but combining different plant proteins throughout the day provides all essential amino acids. The key is total daily intake, not source-by-source perfection.

The practical takeaway: aim for 1.6-2.2g protein per kilogram of bodyweight per day, spread across 3-5 meals. The source matters less than the total. Track it for a week if you've never done so — most people dramatically overestimate their intake.
