What should the daily caloric intake be increased by to promote lean tissue growth?

To promote lean tissue growth, it is crucial to provide the body with a sufficient caloric surplus. The recommended increase of 250-500 calories is generally considered effective for stimulating muscle gain without excessive fat accumulation. This caloric range strikes a balance that allows for the necessary energy and nutrients to aid in muscle recovery and growth while minimizing the risk of gaining excess body fat.

When the calorie intake is raised within this range, it provides the body with the fuel required for increased training intensity and recovery, both of which are essential factors in building lean muscle mass. The lower end of this range (250 calories) can stimulate lean tissue growth in individuals who are less active or who might have a lower starting point of caloric intake, while the higher end (500 calories) may apply to those who are more active or need a larger surplus due to their training regimen.

Exceeding this caloric increase significantly could lead to unwanted fat gain rather than promoting lean tissue growth. Therefore, the 250-500 calorie increase is widely supported in fitness and nutrition literature as an optimal range for those looking to gain lean muscle effectively.
