How Sweet Potatoes Aid Weight Loss

Sweet Potato Diet - How Sweet Potatoes Aid Weight Loss Pinit


It is really a puzzle why potatoes are considered fattening and sweet potatoes as slimming! But if you look the following reasons, you will hold the key to this puzzle. Here’s what you need to know.

1. Low In Calories

Sweet potatoes are low in calories – 100 grams contain about 86 calories and about 100 calories per serving. But 100 grams of peeled potato contain 110 calories or 400 calories per serving! Clearly, consuming sweet potato will keep your calorie consumption in check and your taste buds alive. So, when you follow the sweet potato diet, you will not feel restricted.

2. High Fiber Content

Sweet potatoes are rich in dietary fiber. Dietary fiber aids weight loss by forming a gel-like mesh in the stomach, which makes you feel full and prevents you from overeating. It also encapsulates the fat molecules and prevents fat absorption, promotes stool movement in the colon, and aids the production of good gut bacteria. Hence, consuming the dietary fiber-rich sweet potatoes improves metabolism, digestion, and excretion, leading to weight loss.

3. Low Glycemic Index

Now, this is a little dicey. First, let me tell you what glycemic index (GI) is. It is a number that indicates how the food affects the blood glucose levels after consuming it. When the GI is high, it means that the food causes a spike in the blood sugar levels, which can lead to obesity, diabetes, etc.

But the dicey part about GI is that it changes depending on the way you cook a food. For example, boiled sweet potatoes have a low GI of 44, but when you bake or microwave them, the GI changes to 94. So, you must keep this point in mind when you cook sweet potatoes.

4. High Water Content

The high water content in sweet potato is another reason for it being an effective weight loss aiding food. Dehydration slows down your metabolism. And consuming sweet potato helps rehydrate your cells and kick-starts metabolism. This, in turn, prevents your body from accumulating fat, balances the internal pH, and flushes out toxins. Plus, the water and fiber from the sweet potato will keep you satiated for a long duration.

5. Antioxidant Property

The orange or purple hue in sweet potatoes indicates the presence of carotenoids or anthocyanins. These phytochemicals are antioxidants. Sweet potatoes contain many other antioxidants like copper/zinc superoxide dismutase, catalase, and sporamins. These antioxidants help protect the body by preventing DNA mutation by the harmful oxygen radicals. The less the number of oxygen radicals in the body, the lower your stress or inflammation levels will be, which, in turn, aids weight loss.

These are the reasons sweet potatoes are recommended for weight loss. But what about their carb content? Let’s find out in the section below.

What About The Carbohydrate Content In Sweet Potatoes?

Here’s the fact – 1 ounce of sweet potato contains 5 g carbs.

The carb content of any food can be intimidating when it comes to losing weight. And since sweet potatoes are a close relative of white potatoes (plus they are sweet), you can assume that their carb content is high.

But these are good carbs or complex carbs that cannot be easily digested by humans. And this indicates that sweet potatoes will not spike your blood glucose levels. Plus, they are low GL (glycemic load) foods – the GL of sweet potatoes is 11. The GL is calculated by multiplying the glycemic index (GI) of a food with the number of carbs in 1 gram of that food.

So, it is safe to say that you can consume sweet potatoes without having to worry about their carb content (because that is low). Also, their GI and GL make them diabetes-friendly as well, depending on how you cook them (1). So, is there any scientific evidence that sweet potatoes are good for weight loss? Find out next.

Scientific Studies

Sweet Potato Diet - Scientific Studies Pinit


  • Chinese scientists fed laboratory mice a high-fat diet and supplemented with 15% and 30% sweet potato for 12 weeks. After 12 weeks, the weight and lipid profile of the mice were checked. The mice that were supplemented with 30% sweet potato showed significant improvement in lipid profile, reduced body weight and fat accumulation, and improved kidney function (2).
  • Researchers conducted an experiment on laboratory rats and found out that sweet potatoes can help improve short-term satiety (3). Short-term satiety is important for weight loss as it keeps your hunger pangs at bay after you have a meal. But it also makes you hungry enough after 2-3 hours, thereby keeping your metabolism active.
  • Another group of Japanese scientists fed laboratory mice a high-fat diet and supplemented it with 0.5% or 5% sweet potato peptide for 28 days. By the end of this experiment, they found that VLDL and LDL levels were low, lipid or fat synthesis (lipogenesis) was suppressed, and hunger was low (4).
