If You're Trying to Lose Weight, You Should Probably Stay Away From These Fruits

"Canned fruits can make a perfectly healthy and affordable addition to your diet as long as they aren't packed in sweetened syrup," Jillian Kubala, MS, RD, told POPSUGAR. "Choose fruit canned in water or in its own juice over fruits canned in heavy syrup."

"Although small amounts of dried fruit make an excellent snack when combined with a healthy source of fat and protein like nuts or seeds, eating too much can cause weight gain," Jillian said. "Dried fruit is more caloric than whole, fresh fruit and contains more sugar per serving because it is in a condensed, dried form."

Since whole fruit contains water, which will keep you feeling full and hydrated, it's always better to eat whole fruit over its dried counterpart.

Yes, it's possible to drink smoothies and still lose weight, but you have to be mindful of the type of smoothie you're making. If it's all fruit or a premade bottled version from the store, it could be a sugar bomb.

"Premade fruit smoothies sold at grocery and convenience stores are usually loaded with sugar. Drinking one or two of these smoothies per day could sabotage your weight-loss efforts," Jillian said. "To avoid the sugar shock, make your own smoothie at home. Stick to one cup of fruit then add in greens and a protein source like protein powder, and mix with unsweetened almond milk for a nutritious and delicious alternative to store-bought smoothies."

Amanda also cautions against pineapples, which have up to 17 grams of sugar per one-cup serving.

Mangoes, while delicious, are also higher in sugar: up to 22 grams for a one-cup serving. Juliana Shalek, MS, RD, CDN, and owner of The Nutrition Suite, said these are not the best choice if you are trying to lose weight. If you do decide to eat mango, she advises to pay attention to serving size.

Brooke Alpert, RD, author of The Diet Detox, said grapes may not be the best choice for weight loss since they are higher in sugar: about 16 grams per one-cup serving.

Brooke also advises to be cautious with watermelon, since it can have up to 17 grams of sugar per wedge (about one-sixth of the melon). But it's such a delicious Summer treat that you may not want to avoid it altogether; just be mindful of portion size. One cup of watermelon chunks is just nine grams of sugar.
