Why you shouldn't exercise to lose weight, explained with 60+ studies
When anthropologist Herman Pontzer set off from Hunter College in New York to Tanzania to study one of the few remaining hunter-gatherer tribes on the planet, he expected to find a group of calorie-burning machines. Unlike Westerners, whoincreasingly spend their waking hours glued to chairs, the Hadza are on the move most of the time.

Exercise can undermine weight loss

  • How much we move is connected to how much we eat. And exercise, of course, has a way of making us hungry — so hungry that we might consume more calories than we burned off.

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

It is a very low-carb, high-fat diet. People on a ketogenic diet get 5 percent of their calories from carbohydrates, about 15 percent from protein, and 80 percent from fat. It’s this ratio that will force the body to derive much of its energy from ketones. 

That means eating mainly meats, eggs, cheese, fish, nuts, butter, oils, and vegetables while avoiding sugar, bread and other grains, beans, and even fruit.
