Q: Is it OK to have only one meal a day?
Ans: Anatomically it does not cause any harm. Some people take only one meal a day and lead totally healthy life. But if you want to practice it for weight loss, then you need to understand certain things. Firstly, whether it will be possible for you to have only one meal a day for long period of time? Because due to hunger you may eat whatever available at any time after your one time meal. This eating of second time will not be as per any schedule and as result a signal of possibility of starvation will be sent to the body and in response to it body will store the energy and you will gain weight instead of losing it.
