Why is 16 hours the magic number for fasting?

The 16-hour fasting period in the 16:8 protocol of intermittent fasting is not based on any magical quality. It allows time for the body to deplete glycogen stores and transition into a state of ketosis. This promotes fat burning and can help with calorie restriction for weight loss. Other fasting methods exist, and it’s important to find a sustainable routine that works for you.

How much weight can you lose in a month on intermittent fasting?

The amount of weight you can lose in a month with intermittent fasting varies depending on factors like starting weight, calorie intake, fasting protocol, and activity level. Generally, a safe and sustainable weight loss rate is 1-2 pounds (0.5-1 kg) per week. Combining intermittent fasting with a balanced diet and exercise is key. Individual results may vary, so focus on overall health improvements rather than just the number on the scale. Consult a healthcare professional for personalized guidance.
