New meta-analysis on energy intake and muscle growth

Very interesting in light of previous forum discussions.

Summary by Menno Henselmans:

One important point emphasized by Menno: They find that BMI correlates negatively with muscle growth. One possibility is that having a high BF% impairs muscle growth. Another is that high BMI lifters in the study sample could be more experienced and closer to their genetic potential (haven’t read the text in detail and it may be that this is discussed). Menno also mentions this as a possible interpretation.

I found the following figure neat and interesting:



It seems to me that while a large deficit negatively influences muscle growth, the effect size is highly dependent on the size of the deficit. With a small deficit, muscle loss is rare and muscle growth often happens. With a very small deficit muscle growth seems to be the norm. It would be interesting to see the above graph restricted to lifters who are already experienced with resistance training.
