Catabolism is a series of chemical reactions that break down complex molecules into smaller units and usually release energy. Catabolism provides the energy our bodies need for all its activities.

It's a result of the amount of energy we release into our bodies (catabolism) minus the amount of energy our bodies use up (anabolism). The excess energy is stored either as fat or glycogen in the muscles and liver, with fat being the most caloric dense of the two.
Although becoming overweight is a result of the body storing excess energy as fat, sometimes, hormonal problems or an underlying medical condition may affect metabolism.

It refers to the biochemical processes that occur within living organisms to maintain life. These processes allow us to grow, reproduce, repair damage, and respond to our environment.
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.

It is a common belief that slim people have a higher metabolism and overweight people have a slower metabolism. But, this is rarely the case.
Overweight is in most cases a result of a lifestyle in which one group generally consumes more calories than they need. There isn’t much we can do to significantly change our resting metabolic rate, but long-term strategies, such as increasing muscle mass, may eventually have an effect.

Eating food increases your metabolism for a while because extra calories are required to process your meal. This is called the thermic effect of food (TEF).

Drinking water may speed up your metabolism for about an hour. This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it.
Drinking water can also help you fill up and help you eat less, especially if you drink it half an hour before you eat.
High-intensity interval training (HIIT) involves short, intense bursts of activity and help you burn more fat by increasing your metabolic rate.

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 metabolis...
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: 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.

Not everyone overeats and becomes overweight, and not everyone who becomes overweight or obese develops illnesses like diabetes or heart disease.
There was never a special diet, exercise regimen, or supplement that worked universally to control weight. Through trial and error, we have to discover habits and routines we can stick with that help us eat less and move more.
