1. Stress less. Prevent low blood sugar by eating regular and small healthy meals and keep fruit and veggies handy. Combine at least 30 minutes of physical activity each day will result in a happier healthier you.

2. It's a vicious cycle: You sweat your butt off at the gym, then stuff your face when you get home. If you've worked up a sweat for an hour or more, have a little something within 30 minutes of finishing, even if you don't feel like it. The ideal snack should have carbs to refuel your energy and protein to help repair muscle tissue.

3. Feeling guilty about that giant piece of cake you enjoyed at your niece's birthday party? Don't beat yourself up! It takes a lot of calories—3,500—to gain a pound of body fat. It's about what you do the next day and the day after that's really important... whittle away at those extra calories over the next day or two, preferably by boosting exercise rather than eating too little. When you combine healthy eating with your exercise, you'll notice you feel even better!
