Set up your environment so you don’t snack mindlessly. If you are snacking mindlessly a lot, go somewhere else or move the food elsewhere. You are probably bored – go outside and do something else. 

Sleep early to skip the late night snacking. Our brains have less self-control at the end of the night. When we are tired, the body needs sleep, but our rebellious brains convince our bodies to find munchies in the kitchen fridge and pantry instead. Sleep early to recharge for the morning.
