Do You Need a Calorie Surplus to Gain Muscle?  @lylemcdonaldisright

In 2 recent posts in my Facebook group, people have asked if a calorie surplus is needed for muscle growth. Apparently this is due to some daft idea coming out of the fitness space that it's not.

Which apparently is being based on a single (unread by most) cherry picked paper. Where, as usual, what they say it says is not what it says.

Well here, in my own inimitable way, I'm going to do a deep dive on the topic. Not only will I look at the main paper being invoked but, you know, actual other data on the topic to draw a conclusion.
