What are the different ways of Intermittent Fasting?
1. Alternate-day fasting,
2. 5:2 or 6:1 intermittent fasting (fasting 2 days or 1 day each week),
3. Daily time-restricted feeding (Eating within 8-12 hour window and fasting during the rest of the day)

Cellular, molecular & physiological responses to intermittent fasting
During fasting, cells undergo adaptive stress resulting in range of effects, including increased production of antioxidants, DNA repair, autophagy (removal of damaged or dead cells)& decreased inflammation

Mechanisms involved in IF
1. Metabolic switch: Body’s preferential shift from utilization of glucose from glycogenolysis to fatty acids and fatty acid-derived ketones.
Ketones are the preferred fuel for both the brain and body during periods of fasting and extended exercise.

Of relevance to weight management, this switch represents a shift from lipid synthesis and fat storage to mobilization of fat in the form of free fatty acids (FFAs) and fatty-acid derived ketones.

Conclusions
1. Intermittent fasting (IF) is safe for most,
2. IF has beneficial effects against obesity, diabetes, high BP & cholesterol,
3. IF reduces the risk of dementia and stroke,
4. IF increases longevity
5. IF regimen needs to be modified as per individual goals and needs.
