How The Body Uses Calories
- Basal metabolism is the energy our body needs to keep our cells working and accounts for 65-80% of most adults' caloric consumption.
- The thermic effect of food is the energy our body uses to process food and accounts for 10% of most adults' caloric consumption.
- Physical activity accounts for 10 - 30 % of most people’s caloric consumption .
Controlling Your Own Weight
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.

How we burn energy
There are 3 main ways:
- the basal metabolism, the energy used for your body's basic functioning while at rest
- the energy used to break down food (also known as the thermic effect of food)
- the energy used in physical activity.
Most of the energy you burn is from your resting metabolism.
Metabolism variations
Metabolism can vary a lot between people, and researchers don't understand why.
2 people with the same size and body composition can have different metabolic rates. One can consume a huge meal and gain no weight, while the other has to carefully count calories to not gain weight.

The Ketogenesis process
It supplies energy under circumstances such as fasting or caloric restriction to certain organs (e.g. the brain, heart, and skeletal muscle).
In ketogenesis, our livers start to break down fat into a usable energy source called ketones. Ketones can stand in for glucose as fuel for the body when there’s a glucose shortage.
Once ketogenesis kicks in and ketone levels are elevated, the body is in a state called “ketosis,” during which it’s burning stored fat.
The Keto diet
That means eating mainly meats, eggs, cheese, fish, nuts, butter, oils, and vegetables while avoiding sugar, bread and other grains, beans, and even fruit.
