The Claim
In untrained young men, consuming a daily protein intake of 1.6 grams per kilogram of body weight—whether from plant-based whole foods supplemented with soy protein isolate or from mixed omnivorous foods supplemented with whey protein—results in significant increases in leg-press one-repetition maximum strength after 12 weeks of resistance training.
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.
If young guys who don't usually lift weights eat about 1.6 grams of protein per kilo of body weight every day—whether from plant-based foods and soy protein or from regular mixed diets with whey—they can get noticeably stronger in their legs after 12 weeks of weight training.
See the scientific wording
A daily protein intake of 1.6 grams per kilogram of body weight, whether from plant-based whole foods plus soy protein isolate or from mixed omnivorous foods plus whey protein, supports significant increases in leg-press one-repetition maximum strength in untrained young men following 12 weeks of resistance training.
What the research says
1 studyThe study found that untrained young men gained similar leg strength on a plant-based diet with soy protein as they did on a meat-inclusive diet with whey protein, as long as both got 1.6 grams of protein per kilogram of body weight each day.
