Fasting is a difficult question. In the short term it can offer many benefits and for years I fasted regularly for 24-72hrs. As a teenager I had to fast to be able to go to school so from Sunday night until Friday afternoon I basically lived off of fluids. Any time I had to go out I would fast up to 24hrs ahead of time.
Once I had my k pouch done I could and did eat normally...my body did not appreciate that. It was not used to the intake and calories.
I started eating according to Fit for Life in 1991...only fluids and fruits in the mornings, separating protein and carbs into different meals and Fasting one day/week + 3 days every beginning of season...
It has worked very well for me for 30 years.
But in the long run fasting regularly or too often can deregulate your metabolism.
Your body is built to deal with both feast and famine.
When you fast it slows down all systems of your metabolism and goes into famine mode...which is why regular dieters find as years go by that they need to keep reducing their calorie loads in order to lose weight.
Your system slows to the point where you can subsist on under 800 calories per day. More than that and you gain weight...your body stocks calories immediately because it is preparing itself for the next famine.
It makes it very difficult, down the road, to re-regulate your metabolism. (That requires regular small meals and consistent exercise)
Which is ashame if you didn't have a problem to start with.
Intermittent or occasional fasting may have its place in some people's lives but it is not a one-size-fits-all solution nor is it a miracle.
It can even be dangerous for those who have blood sugar problems whether they know it or not.
Whatever you decide to do, please check with your doctor first and have blood work done along the way.
