It is a common myth that all that matters for weight loss is calories in, calories out.
Of course, calories matter. But the types of foods we eat are also important.
Here are 3 examples of how “a calorie is NOT a calorie.”
-Fructose vs. Glucose: Fructose is more likely to stimulate hunger, increase abdominal obesity and insulin resistance, compared to the same amount of calories from glucose (1, 2, 3).
-Protein: Eating protein can raise the metabolic rate and reduce hunger compared to fat and carbs (4).
-Medium vs. long-chain fatty acids: Fatty acids that are of medium length (such as from coconut oil) raise metabolism and reduce hunger compared to longer chain fatty acids (5, 6, 7).
Bottom Line: A calorie is not a calorie. Different foods affect our bodies, hunger and hormones in different ways.
