You find a way to eat fewer calories and you stick with it until you reach your fat loss goal. Restricting calories is painful, sometimes annoying, but not the hardest thing to do.
The hardest thing is watching your strength fade away.
Minimizing muscle loss is part of the goal, and we fight it by lifting heavy; sets of five to seven reps. And because of that, we often get injured. Not the kind of injuries to keep us out of the gym, but painful enough to be noticed.
Those are messages. Messages from your body telling you to take it easier, to lower the weight.
You should listen.
