Study: Lean Protein Boosts Muscle Growth Over High-Fat Protein
Imagine your muscles are like building blocks, and after a workout, they need to be repaired and grow.
This study looked at what happens when you eat different types of protein after exercising.
Scientists gave people either lean meat or high-fat meat, both with the same amount of protein.
They found that the lean meat helped the muscles build faster because the body could use the building blocks quicker.
High-fat meat may slow down this process, which means the muscles might not repair and grow as fast.
So, if you want to help your muscles grow quickly after exercise, lean protein is a better choice!
A 2025 study from the University of Illinois investigated lean versus high-fat protein.
Participants performed resistance workouts and consumed either lean or high-fat pork burgers.
Both burgers had equal protein content.
Lean protein consumption resulted in higher muscle protein synthesis (MPS).
High-fat content may delay amino acid delivery to muscles, impacting growth.
