Myth: Metabolism is genetic, can't be changed.

Your genes do influence your metabolism, but, unusual genetic conditions aside, lifestyle habits affect it more. The amount of exercise you get and the choices you make when you feed yourself are more important factors.

Myth: Those with a fast metabolism can eat freely.

People with faster metabolisms don’t necessarily put weight on as quickly as those with slower metabolisms. But a balanced diet comes with seriously consequential health benefits unrelated to weight maintenance, including good heart health and the prevention of certain cancers.

Myth: multiple smaller meals a day are better than 3 regular meals.

Some research is coming out saying maybe it’s better to eat two or three modest meals a day. People often miscalculate the calories in the smaller meals resulting in a higher caloric intake than they would consume with three regular meals.
