The Claim
Does the type of protein (whey vs. soy vs. meat) affect how many calories you burn?
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Whether you get your protein from chicken, tofu, milk, or fish, it doesn’t make your body burn more calories — the type doesn’t matter, only the amount.
See the scientific wording
Different sources of dietary protein (e.g., whey, soy, casein, fish, pork) have no measurable effect on diet-induced thermogenesis, total daily energy expenditure, or resting energy expenditure in humans, based on current evidence from 2–3 studies per comparison.
What the research says
1 studyThis big study looked at many experiments and found that whether you eat protein from whey, soy, fish, or pork, your body burns about the same amount of calories digesting it — so the source doesn’t matter, just the amount.
