Regular Fasting as a way of life


Regular Fasting as a way of life
Fasting is the act of voluntarily abstaining from food or drink (or both) for a fixed period of time. Most religions advocate fasting firstly to increase piety and secondly as part of  healthy living. Fasting takes various forms, varying from partial day fasts to partial meal fasts. But the overall caloric intake should be reduced. Daily caloric intake requirement varies according to sex and age. But we can assume men need 2000 calories and women need 1500 calories daily. The above diet recommends fasting 2 days a week. Fasting day meals should consist of 2 meals of 300 calories. The rest of the week you can take your usual diet. It is good to separate the 2 fasting days. So Mondays and Thursdays will be good. Incidentally, Mondays and Thursday fasts are followed by many religions including Hinduism, Judaism, traditional Christianity and Islam.
Why do I fast and not lose weight?
Contrary to logic, prolonged fasting actually reduces appetite. But for there to be weight loss, the overall caloric intake needs to be reduced. The fasting day caloric intake needs to be reduced to a total of 600 calories. That's about 1½ murtabak or 4 chappatis. (refer to table below)

Most of us make the mistake of overcompensating when we breakfast with high caloric food. If we are selective with the types of food, weight loss is inevitable. The recommended weight loss is ½ to 1 kg a week.

Fasting regularly may be a feasible option for sustained weight management. Moreover, it does not involve paying thousands of dollars to a beauty saloon and may in fact save you some money.
