On the YouTube channel BrainCraft, host Vanessa Hill explains how carbs are broken down by the body and their positive and negative effects.
When you eat too many carbs, your blood sugar rises. Your pancreas then releases insulin to bring your blood sugar down and store some of it as energy for later.
When you eat complex carbs, such as whole grains and vegetables, your body converts the natural sugars into energy.
But it's different with refined carbs such as white bread, pasta, muffins, chips and soda.
Insulin is a fat storage hormone and when more insulin circulates in your blood stream, your body converts the carbohydrates to fat and stores them on your buttocks, thighs, abdomen and hips, making you gain weight.
Too much sugar in the brain can lead to cell aging and death, and insulin regulates blood sugar levels to prevent this.
But if you eat more sugar than your body needs, you can develop insulin resistance, which can lead to type 2 diabetes.
Vanessa says that the important thing to remember is that food is fuel, and that carbs, protein, and fat should all be eaten in moderation.
