Gelatin is practically fat- and carb-free, depending on how it's made, so it's quite low in calories.
Studies show it may even help you lose weight.
In one study, 22 people were each given 20 grams of gelatin. As a result, they experienced a rise in the hormones known to reduce appetite, and reported that the gelatin helped them feel full (20Trusted Source).
One study gave 23 healthy people either gelatin or casein, a protein found in milk, as the only protein in their diet for 36 hours. The researchers found that gelatin reduced hunger 44% more than casein (23Trusted Source).
SUMMARY:Gelatin may help with weight loss. It is low in calories and has been shown to help reduce appetite and increase feelings of fullness.
