Avoid the afternoon sugar slump. Many people tend to get hungry mid-afternoon and they often reach for a sugary snack or candy. While this gives an immediate bump in energy levels, it doesn't last for very long, causing you to be even hungrier. When that mid-afternoon craving comes along, have a supply of fresh fruit nearby to satiate your hunger. If you are going to be dining at a restaurant that serves large portions,ask the server to put half of your meal into a take home box before the food is brought to you. If you are not tempted to eat more than what you have available, you won't. This can help you practice your portion control.
