Metabolic confusion diet is one of the latest fad diets that promises you can lose weight while still eating what you want.
It is similar to intermittent fasting, but without the extremes of energy (calorie) restriction.
A person on the diet might eat only 1,200 calories one day, then eat 2,000 calories the next.
These diets may be successful in getting people to eat less but may actually reinforce bad eating habits and poor diet quality.
Research has shown people following these diets have a less nutritious diet.
If the metabolic confusion diet functions similarly to intermittent fasting, it may have other benefits beyond just weight loss.
Intermittent periods of energy restriction improve glucose (blood sugar) and lipid (fat) metabolism.
Manage fuels (carbohydrates, fats) in the body, known as metabolic flexibility.
Improves insulin sensitivity which reduces overall risk from disease, such as cardiovascular disease and diabetes.
