A 72-hour fasting cumulatively puts one at 7,000 calorie deficit equivalent to about two pounds of fat loss. “If done for longer periods the 72-hour fasting may adversely affect weight and cause weight gain because of adaptive thermogenesis.Denying your body food for 72 hours can lead to dizziness, headaches, low blood sugar, muscle aches, weakness, and fatigue. Anyone who fasts for longer than this may experience anemia, a weakened immune system, liver and kidney problems, and an irregular heartbeat.Phase 1: 0 to 4 hours– “Anabolic” phase, which is business as usual as your body breaks down nutrients from food and converts them into energy and body tissue. Phase 2: 4 to 16 hours– “Catabolic” phase where you begin to metabolize body fat as energy and autophagy is activated.

Will I lose muscle if I fast for 3 days : Fasting can cause muscle loss, but it's normally well after 24 hours. And that's not something commonly done by those practising intermittent fasting.
