If you are exercising and dieting and you still can’t lose weight, this could be why. Here’s a list of 21 foods that you think are healthy, but are actually making you pack on the pounds:

1. Yogurt

Added sugars and lots of fat make yogurt one of the worst breakfast foods. And all that hype about the good probiotics? This study shows that there’s really no benefit.

2. Whole wheat products

Whole wheat is naturally bitter, so whole wheat products usually have a lot of added sugar. You should also be careful of products that are “multigrain,” which may not include the whole wheat portions.

3. Tortillas

There are many kinds of tortillas-corn, wheat, whole grain and even spinach-but beware of high fat and sodium levels.

4. Salads

Obviously, it’s not the greens themselves that are the problem. The problem is all the add-ons: the dressing, the croutons, the salty sunflower seeds, etc.

5. Energy bars

They are disguised as healthy snacks because they’re associated with working out, but don’t be fooled. One little bar can have over 350 calories, which come from high-fructose corn syrup and other unhealthy additions.

6. Mashed potatoes

Potatoes naturally have a lot of vitamins and fiber, but most of those healthy elements are in the peel, which is lost in mashed potatoes. Then you add the B.utter, the sour cream and the salt, and suddenly this staple side dish has lots of fat and none of the fiber.

7. Dried fruit

Fruit naturally has a lot of fiber and vitamins, but dried fruit usually has a lot of added sugar. Also, the drying process reducesthe Vitamin C levels in the fruit.

8. Trail mix

High sodium in the nuts, added sugar in the raisins and high fat content mean that this isn’t the healthy snack you thought it was.

9. Sports drinks

The levels of sodium and sugar in sports drinks are so high that they can damage your insulin sensitivity.

10. Protein powder

Too much protein can damage your liver and kidneys. Besides, protein is more easily digested when it comes in natural forms like tofu, legumes and flaxseed.

12. Diet Soda

It saves you the calories, but it’s not proven to make you lose weight. In fact, it’s associated with a higher risk of diabetes.

13. Skim/lowfat Milk

Taking out the fat also means taking out a lot of the minerals. Some kinds of skim milk come fortified with extra Vitamin D and other minerals to try and make up for it, but you’re better off just drinking 2%.

14. Margarine

In addition to having harmful chemicals, margarine can raise your cholesterol.

15. Fruit juice

Added sugars and high-fructose corn syrup are lurking behind labels of health-looking fruit juice.

16. Canned Soup

Depending on the kind of soup, you can find extremely high levels of sodium.

18. Veggie Chips

The deep-frying process adds a lot of fat and strips away the natural nutrients.

19. Fruit cocktails

That high-fructose corn syrup preserves fruit and makes it sweeter, but it also adds way too many calories.

20. Peanut B.utter

Peanut B.utter has a lot of protein, but it has a lot of fat too. Eat it in moderation. Almond B.utter is sometimes a better alternative.
