Do some foods contain zero calories?
The theory of zero calorie foods is that the body will burn more calories metabolizing and cooking the food than the calories the food contains.
This is a process called thermogenesis, and it’s how your body heats itself up – thus zero calorie foods!
These foods were selected based on two factors.
The first was that they must be full of nutrients like vitamins and antioxidants for your health.
The second is that they must be under 100 calories per 1 cup serving.
1. Apples
Apples are one of the healthiest fruits on the planet containing antioxidants, vitamins, minerals, and even pectin (which has been shown to reduce hunger).
Eating an apple can be a great snack between lunch and dinner as it will keep the body full while providing a small energy boost.
It also helps people to stay away from eating junk food and will diminish cravings for sugary sweets that everyone knows is damaging to health.
