What type of fasting involves consuming less than 25% of baseline energy needs on fasting days?

The type of fasting that involves consuming less than 25% of baseline energy needs on fasting days is known as alternate day modified fasting. This approach typically alternates between days of minimal caloric intake (which is below 25% of one's daily energy requirements) and days of regular eating. The idea behind this method is to create a significant caloric deficit over the week, which can support weight loss and potentially provide health benefits associated with reduced calorie consumption.

This modified approach differentiates itself from regular alternate day fasting, where one might completely fast on designated days, leading to zero caloric intake rather than a reduced-calorie intake. Thus, alternate day modified fasting allows for some caloric intake while still promoting similar benefits related to weight management and metabolic health. Understanding this distinction is crucial for anyone exploring different fasting protocols for health or weight loss purposes.
