Cinnamon’s Effect on Appetite

Cinnamon has a number of potential health benefits 1. According to the Pennington Biomedical Research Center, cinnamon may help in the treatment of type-2 diabetes because the spice can mimic insulin 1. Since insulin is the hormone that changes excess sugar into fat, it is reasonable to conclude that cinnamon can help prevent weight gain 1. Additionally, cinnamon slows down the absorption of carbohydrates in the small intestine, which can helps you feel full longer and decrease appetite 1.

A 2010 study published in the “Archives of Biochemistry and Biophysics” investigated the effects of cinnamon on insulin resistance 13. Rats were fed a high fat and high fructose diet. Some rats also received 20 g of cinnamon 1. The study found the rats that had cinnamon along with the high fat diet were less likely to accumulate a specific type of fat that was found in rats who were fed the high fat and high fructose diet without cinnamon 1. Researchers stated the results suggest cinnamon alters body composition and helps improve insulin sensitivity 13.

Blood Glucose in Humans

A 2007 study published in the “American Journal of Clinical Nutrition” looked at feelings of satiety and blood glucose levels in healthy humans. Although previous studies had examined the role of cinnamon on people with diabetes, this study used 14 healthy adults 1. When participants included cinnamon on their rice pudding, researchers found gastric emptying was significantly delayed 1. Participants noted no difference in their feelings of fullness. The research also found that cinnamon in the diet significantly reduced the postprandial glucose response 1.

Cinnamon can be added to beverages like tea and cocoa 1. Also add the spice to fruit, rice pudding, toast and other foods to regulate blood sugar.
