This study compared a typical bodybuilder’s diet (~1g/lb protein) with a diet even higher in protein (~1.5g/lb). Both groups underwent an 8-week training program and had similar gains in muscle mass. However, the high protein group lost significantly more fat mass even while taking in about 400-500 more calories per day. Similar studies have been performed with less intense training protocols and didn’t get as significant of results. The takeaway is that you have to eat a high protein diet AND train incredibly hard to reduce body fat and build muscle at the same time.
