When you’re trying to lose weight, patience and motivation are key, along with a healthy diet of whole grains, lean meats, nuts, and seeds, as well as vegetables and fruits.

Fruits often make up a major part of a weight-loss diet, but not all fruits are useful if you’re trying to lose weight. Most of us think we can eat as much fruit as we like when on a diet, but there are some you should avoid if you are trying to shed the pounds.

Some of them are high in calories and sugar, so are best avoided. Read on to find out which fruits are not diet-friendly.

1. Avocado

Avocados are extremely popular, but 100 grams of avocado contains around 160 calories. Although it is full of healthy fats, it’s easy to eat too much of this fruit. Don’t eliminate avocados completely, but do keep an eye on how much you are eating.

2. Grapes

Grapes are full of sugar, and it’s easy to end up eating a whole bunch in a day! 100 grams of grapes contain 67 calories and 16 grams of sugar, so eating them regularly can soon add up to a whole lot of unwanted calories.

3. Dried Fruits

Dried fruits such as raisins, prunes, apricots etc. make great snacks, but the downside is that they have more calories per gram than fresh ones, as the water has been removed from them. One cup of raisins contains around 500 calories, and one cup of prunes around 450 calories – that’s a lot, if you’re trying to lose weight, so it’s best to limit the amount of dried fruits you eat.

4. Bananas

Bananas are very healthy, and make a great snack, but eating more than one of them a day can soon derail your weight loss goals.

One banana has around 150 calories, and 37.5 grams of carbs. If you had two or three a day, that would be 300-450 calories just for the bananas alone!

As bananas are low on the glycemic index, they release their carbs slowly, so they can make a satisfying snack when eaten in moderation.

5. Mango

Sweet tropical fruits like mango and pineapple taste gorgeous, but they are full of sugar. If you’re trying to lose weight, it’s best to eat these fruits in moderation, or you could find that your weight loss slows right down.
