1. Being unprepared Without healthy foods in the fridge, you are more likely to nosh on high-calorie foods. Stock up on low-cal foods like fruits and veggies, string cheese and yogurt and have an eating plan in mind. If you just grab the first thing that comes to mind, you are more likely to end up eating something unhealthy.

2. Skipping meals “You’re less likely to overeat if you eat more often,” explains Joan Salge-Blake, MS, RD, spokesperson for the American Dietetic Association. Spread your daily calorie intake between 4 to 6 small meals a day.

3. Declaring foods “off-limits” Swearing off ice cream and chocolate just makes them more tempting. Instead, allow yourself a small taste. Or go for a healthier version with lower calories.

4. Reaching for the weight-loss “stars” Research shows that when it comes to weight loss, the bigger your goals, the more likely you are to fail. Salge-Blake suggests aiming for one to two pounds per week.

5. Office meetings The cookies and birthday cakes in the afternoon meeting are tempting, but those calories add up. Bring something to munch on like an apple or nuts.

6. Low-fat foods They are often high in sugar and artificial additives. Lean proteins and healthy fats are a much better option.

7. Drinking calories Drinking high-calorie beverages makes you less likely to feel full and more likely to overeat. Water is your best bet.

8. Not exercising Eating clean is only half the battle. Aim for at least 30 minutes of exercise, at least three days a week.

9. Feeling stuck Your diet will hit a plateau. Look for ways to reinvigorate your weight loss efforts; buy a new cookbook filled with creative recipes or invite a friend to go for a brisk walk.

10. Feeling hungry Think it is a good idea to hold off on eating until your stomach starts growling? Think again. “You’re more likely to make poor choices when you are starving,” says Salge-Blake. [source: Oxygen]
