More Hunger with Potatoes vs. Sweet Potatoes?

Answered on August 19, 2014
Created January 17, 2011 at 6:20 PM

I've been experimenting with the two, and the amount of satiety that I get from an identical meal with potatoes is noticeably less than if I ate sweet potatoes instead. Seems like the potato starch is converted completely into glucose and thus causes a greater insulin response, but the fructose in the sweet potatoes should interfere with satiety as well. I keep testing it with the same result; anyone else experience this?

For what it's worth, I'm eating about 2 golfball-sized purple potatoes per day with a negligible amount of carbohydrates from other sources.

Edit: Interesting answers here. You know, it's funny because when I eat sweet potatoes I eat less food in general but I don't lose fat, but with potatoes I eat more food, more carbs but I lose fat. This must be the result of the higher fructose content in the sweet potatoes.

could this be a fiber to starch ratio?

Are you sure that the amount of sweet potatoes you are eating has the same number of calories as your regular potatoes? Sweet potatoes have a lot more fiber, so on a weight by weight basis they will simply have less calories than potatoes.

It could be calories. Data is from nutritiondata.com and one website that had info on the purples is caloriegallery.com. But I remember from looking this up previously that purples definitely have fewer calories than russets.

Sweet potato (what you say you are eating) 100 grams = 90 calories

Yam (what you might actually be eating) 100 grams = 116 cals

Purple potato 100 grams = 82 cals

Russet potato (just to compare) 100 grams = 97 cals

2 'golf-ball' sized potatoes is barely anything and may even be less than these amounts listed.

Great question! My go-to expert in all things spud is Dr Kathleen DesMaisons @ radiantrecovery.com She has written about potatoes, satiety, and sweet potatoes causing a more gradual insulin rise which makes them more appropriate for those with diabetes, IF I'm remembering correctly.

I have been recently adding in white potatoes (which my wife favors) after eating sweet potatoes as my main source of carbs for six months or so. I confess I have noticed zero difference.

I am more satiated after a meal with sweet potatoes. For some reason nightshade potatoes cause me to be sleepy and more hungry after I eat them. Haven't tried organic white potatoes yet though.

I'm much fuller after eating a sweet potato and for longer than a potato. Not even close.
