5:2 – that’s 5 days of normal eating, where you pay little attention to calorie control, as well as 2 days where you reduce your calorie intake to 800 calories per day.
A key driver for success of 5:2 is psychological: when you choose a 5:2 routine you avoid the “diet treadmill” that can feel like a rotation of denial.
In our experience it is easier to resist the temptation of unhealthy choices by saying to yourself, “I will have it tomorrow”. Then tomorrow comes and maybe you eat it. But sometimes you don’t.
Intermittent fasting also teaches you better ways of eating. If you satisfy your hunger on fasting days by eating vegetables and good protein, then over time you’ll discover that when you get hungry you are more likely to crave the healthy stuff.
An important result of calorie restriction is to switch on a process called autophagy. Autophagy, meaning ‘self eat’, is a process by which the body breaks down and recycles old and tired cells; just as with a car, it is important to get rid of damaged or ageing parts if you are going to keep things in good working order.
