Junk Food
It may seem like a no-brainer that eating junk food and having a fast metabolism doesn't go together, but it actually goes deeper than that. Any excess of calories can lead to weight gain, but as registered dietitian Kristin Kirkpatrick explains, "junk food, in particular, requires a lot less energy from the body (known as the thermic effect) to process and break down, compared to complex carbohydrates or protein." While the latter requires more of a calorie expenditure to break down, the former gets broken down quickly, so quickly in fact that you may find yourself hungry soon after eating, sluggish from a sugar crash, or bloated from a sodium overload. Eating junk food can also affect gut microbiota and have an impact on one’s resting metabolic rate.
