Fasting is very likely the oldest health practice there is — every tradition I am aware of has some form of it, from a single skipped meal to extended water fasts under supervision.
Traditional fasting takes many forms: a fixed weekly partial fast (common across Indian tradition, often tied to a specific day), fruit-only or juice-only days, and longer supervised fasts undertaken at a nature cure centre. The common thread is giving the digestive system a genuine rest, not simply restricting food as a general rule.
Shorter fasting patterns (such as time-restricted eating) have real modern research behind them for metabolic health in appropriate candidates. Longer water fasts are a much more serious undertaking, with a real risk profile, and the traditional insistence on supervision for these is sound advice, not excess caution.

If you are unwell — and particularly if you have a serious illness such as cancer, diabetes or heart disease — please stay under the care of a qualified doctor. Nothing here should replace that care or delay it. Talk to your physician before changing anything about how you eat, fast or treat yourself.
