Why does my body feel cold when fasting?

Within your eating window, you will still consume the amount of calories your body needs to function optimally. If you constantly feel cold during intermittent fasting, this is a sign you need to consume more calories within your eating window.

What happens to your body the longer you fast?

With no carbohydrates coming in, the body creates its own glucose using mainly fat. Eventually, the body runs out of these energy sources as well. Fasting mode then becomes the more serious starvation mode. At this point, a person’s metabolism slows down, and their body begins burning muscle tissue for energy.

How does your body react when you fast?

Essentially, fasting cleanses our body of toxins and forces cells into processes that are not usually stimulated when a steady stream of fuel from food is always present. When we fast, the body does not have its usual access to glucose, forcing the cells to resort to other means and materials to produce energy.

How does the body obtain energy during fasting?

Most of our body’s tissues can obtain energy by breaking down fatty acids, but not the brain, which needs glucose. To supply glucose molecules to the brain during the early stages of fasting, a process of breaking down proteins in muscles takes place, releasing glucose building blocks into the blood stream.

Why do I feel cold after fasting for a week?
