Are you eating enough?
Most people have the exercise part down but are you fueling your body adequately? With your busy life do you often forget to eat breakfast and maybe even lunch then suddenly find yourself sitting at your desk with a grumbling stomach?
Consider food prepping.
Prepare yourself on the weekends and give your body the nutrients it craves eating not just 3 meals a day but add in a mid-morning snack and afternoon & evening snack. Keep that metabolism up for optimum calorie burning!
