The term "5/2" often refers to a type of intermittent fasting schedule where individuals eat normally for five days of the week and restrict their calorie intake on two non-consecutive days. This approach allows for flexibility in meal planning while promoting potential health benefits, such as weight loss and improved metabolic health. In the context of nutrition, the 5:2 diet encourages participants to consume around 500-600 calories on fasting days. This method has gained popularity due to its simplicity and the ability to fit into various lifestyles, making it easier for people to adhere to compared to more restrictive diets.
