Metabolism and Genetics
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: Supplements can speed up your metabolism.
Over-the-counter products that claim to boost metabolism often don’t have calories, don’t directly impact your metabolism and have well documented potentially dangerous side effects and interactions with prescription drugs. Natural alternatives such as spicy foods do boost your metabolism, leading to more calories being burned, although not for long.
Myth: Skinnier people have faster metabolisms.
It’s more about body composition than body size when it comes to metabolism. Metabolism depends on the composition of protein mass you have—muscle is more metabolically active, meaning the more muscle you have, the more calories you burn when you’re resting. This is why lifting weights is one of the best ways to speed up your metabolism, it adds muscles.
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.

When people use the word "metabolism" they are often referring to catabolism and anabolism. People's body weight is a result of catabolism minus anabolism.
Researchers say breakfast doesn't kickstart the metabolism and may not be the most important meal of the day. Different studies have found that skipping breakfast doesn’t lead to weight increase and have no impact on resting metabolism.
Start your day with lean protein, which burns twice as many calories during digestion as fat or carbs. But don't stress about squeezing it in before 9 am.
Some studies found green tea and oolong tea can increase metabolism by 4-5%. The teas help convert some of the fat stored in your body into free fatty acids, which may increase fat burning by 10-17%.
