Creatine may be the most scientifically proven supplements on the market. It has been proven to lead to significant muscle growth over time. Although creatine doesn’t directly increase fat utilization within the body it will lead to a higher metabolism indirectly. Creatine intake boosts muscle growth and retention. That extra muscle tissue will, in turn, create a higher metabolic rate. This is why creatine supplementation is a good choice for any fat loss plan.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
