"Since many of these foods are the primary source of fiber in our diets, many people that start the keto diet will notice constipation as a side effect of eliminating those carbohydrate-rich foods," Fillenworth says. "Fiber is crucial to maintaining consistent bowel movements, helps to keep our GI system healthy, and creates a feeling of fullness when eating." Women should aim for 25 grams of fiber per day to keep things ~regular~.
The main proposed benefit of the keto diet is losing weight, though there is some research showing it may help with certain health conditions. The weight loss comes because the body burns fat and because the fat you’re taking in is filling, which can lead you to eat fewer calories overall, says Abby Langer, RD, founder of Abby Langer Nutrition, who is based in Toronto, Canada.
