Resistance training increases the integrated rate of myofibrillar protein synthesis (MyoPS) and the synthesis rates of individual skeletal muscle proteins in older men during energy restriction, regardless of whether dietary protein is distributed evenly or skewed.

If you are an older adult trying to lose weight, focus on resistance training. The timing of your protein intake (whether you spread it out or eat it all at once) does not significantly impact your muscle protein synthesis rates as long as you are training. Prioritize the training stimulus over complex nutritional timing.
