How do the amino acids in a soy patty and a beef patty compare once they reach your blood?
In a trial he helped design, Dr. David Church matched a 4-ounce beef patty against a soy-based burger. He had to double the soy to roughly match the single beef patty in essential amino acids. The blood amino acid levels shocked him.
David joins me at Protein Summit 3.0 to explain what happened.
He also tells me why muscle protein breakdown is so much harder to measure than synthesis, and shares insights from his 21-day testosterone study, where the men on testosterone lost all of their weight as fat while the placebo group lost about half of theirs as fat-free mass.
