Originally Answered: Sweet potatoes for weight loss?
Yes, sweet potatoes are the healthier alternative. They give you extra vitamins, minerals, protein, and energy while you are using weight without the fat.
Regular potatoes actually aren't bad as they say. The only way starch gets turned to fat is if you go beyond your calorie limits for the day. Potatoes don't have any fat, it's what you put on them that makes them fattening (butter, sour cream, beef chili, cheese) or how they are prepared (fried in fat like French fries or chips). Potatoes have everything you need for good health compared to donuts or white bread that are not good for you. I wouldn't stress about the potatoes.
If you are on one of those high-protein diets, you'll need to be very cautious. They are not recommended for longer than 4 months because of the heart and kidney damage, fatigue, constipation, and colon cancer issues.
It's actually possible to lose more weight on a healthy, high-fiber, wholesome carb diet as well as have better health. In that case, you would want to include potatoes liberally into your diet as well as brown rice, beans, and lots of vegetables.
