Get Enough Sleep
And while diet and exercise are important for fat loss, many people tend to overlook another important lifestyle habit: sleep. A lack of sleep could increase the production of the stress hormone cortisol.
"When you are sleep-deprived and cortisol levels increase to keep the body running, you will likely experience fatigue, increased food cravings, mental fog, and lower 'real' energy," Eric explained. "All of these will impact your effectiveness in the gym and impair your adherence to an eating plan."
Aim to get seven to nine hours of sleep a night.
