What happens if you fast for a long time?
If you continue fasting indefinitely there comes a point where the fast turns into starvation. You obviously don’t want to overstep this mark! For when your fat stores are finally depleted, the body has no choice other than to devour muscle tissue, as well as feed from your inner organs. You’ll do yourself serious damage. Fortunately, though, the body sends a clear sign: extreme hunger. Although it’s unlikely you’ll miss this red flag, two other less obvious scenarios also demand the end of a fast – and it’s here, again, that fasting under supervision can help. The first possibility is that you run out of muscle tissue before you deplete your fat stores. In order to power your body as a whole, it’s true that ketosis is extremely efficient. The problem is that the brain demands another fuel entirely: glucose. And this cannot easily be metabolised from fat tissue. Instead, the body must extract it out of muscle. The second possibility is that you deplete your electrolytes (blood salts). Although unlikely, it’s extremely dangerous! For this reason it’s advisable to have your blood tested at relatively regular intervals after the first 7-10 days of fasting.
