Jim Katsoulis argues that sleep is the single most important habit for weight loss. Without enough rest, your mindset and energy collapse, making it harder to eat well or exercise. Go to bed earlier first, everything else follows.

the number one discipline to lose weight. And I believe this discipline is more important than even eating because it's so fundamental and foundational to everything else that impacts your weight. And what that discipline is, is sleep discipline— the ability to go to bed earlier so that you get the rest and recovery that you need, so when you wake up, you have the mindset, the clarity, the energy to make the choices that allow you to live in the body you want to live in.
