"Both soluble and insoluble fiber in sweet potatoes slow down digestion. Sweet potatoes are also a low glycemic food, so eating them in moderation will not cause a spike in blood sugar levels," said Destini Moody, a nutritionist in the US.

Sweet potatoes are packed with nutrients, including essential vitamins and minerals like vitamin A, vitamin C, potassium, and magnesium. Here are some reasons why sweet potatoes can help you lose weight, according to Eat This, Not That!.

Provides a long lasting feeling of fullness

Sweet potatoes provide fiber and complex carbohydrates to the body, giving the eater a feeling of fullness, thereby reducing calorie intake.

Sweet potato skins contain some insoluble fiber, which cannot be broken down during digestion and contains no calories, so they can reduce the amount of food we consume, Moody said.

Contains many nutrients

Sweet potatoes are rich in vitamins, minerals and antioxidants but low in calories compared to some other starchy foods. Therefore, sweet potatoes are very suitable for low-calorie diets for weight loss.

Provides prebiotics

Sweet potatoes also contain prebiotics, compounds that promote the growth of beneficial bacteria in the gut. Prebiotics aid digestion and help keep the gut microbiome healthy.

A healthy gut microbiome can help with better weight control, says Moody.

Contains complex carbohydrates

Thanks to their complex carbohydrate content, sweet potatoes provide a steady source of energy, limiting cravings for sweets.

Compared to other carbohydrates with the same number of calories, sweet potatoes contain more water and complex starch. Over time, this helps the weight loss process effectively.

No spike in blood sugar

Sweet potatoes have a relatively low glycemic index, so they have a slow impact on blood sugar levels. This means you won't experience energy drops and fewer sweet cravings.

According to Ms. Moody, sweet potatoes do not cause the body to spike blood sugar levels, lack energy or feel hungry quickly.
