Keep to an eating and exercise schedule. Avoid grazing all day long.
Stock up on healthy food items, not junk food. Load up on frozen and canned fruits/vegetables, dried beans/grains, and lean meats.
Prepare and portion out healthy snacks.
Keep portions under control - make 1/2 your plate vegetables, 1/4 carbohydrates, and 1/4 protein.
Stay busy to avoid eating out of boredom.
Have healthier snack/comfort food options available. Ideas like low fat chocolate pudding, single servings of dark chocolate, or single serving 100 calorie packs.
