The term "5-2" often refers to a specific type of intermittent fasting schedule. In this approach, individuals eat normally for five days of the week and restrict their calorie intake to about 500-600 calories on the remaining two days. This method is popular among those looking to manage their weight or improve their overall health. The 5:2 diet is based on the idea that intermittent fasting can help reduce body fat while still allowing for regular eating patterns. Many people find this approach easier to maintain compared to daily calorie restriction, as it provides flexibility in meal planning throughout the week.
