In the recent years, fasting is also being recommended for flushing out toxins as a part of detoxification, for losing weight, medical and sometimes even for experimental reasons.

However, fasting these days is just not confined to food alone. Water fasting is a latest, emerging trend to lose weight and to stimulate autophagy, a natural, regulated mechanism of cell that disassembles unnecessary components.

Improves Insulin and Leptin Sensitivity:

Insulin and leptin, the most important hormones play a major role in metabolism and water fasting could make your body more sensitive to insulin and leptin. This in turn, insulin is better produced by reducing blood sugar levels while leptin helps in body at better processing of hunger signals and help in losing weight.

Lowers Cholesterol:

Water fasting for 24 to 72 hours may reduce the levels of triglycerides and cholesterol and help in protecting the heart from free radicals. Free radicals damage the parts of cells and may trigger chronic diseases and water fasting prevents the growth of free radicals.

Who Shouldn’t Water Fast:

Do not go for water fasting if you are suffering from gout, chronic kidney disease, eating disorders, heart burn.
