The 5-Factor Diet

What is it?

This simple diet, created by personal trainer Harley Pasternak, is designed to last five weeks. It consists of five small meals a day, combined with 25 mins of exercise broken down into five five-minute bursts.
Pasternak created the 5-Factor diet with Hollywood actors in mind - the simple meals are designed to be rustled up on set and the short exercises can be done between takes and Eva Mendes, Katherine Heigl and Halle Berry are all said to be fans.
You also get one cheat day every week so you can eat whatever you want!

How does it work?

Eating regularly will keep you feeling full and stave off dangerous hunger pangs. Each meal contains up to 300 calories and on top of that, you're also allowed two snacks of around 200 calories each.
The meals are made up mostly of low-fat protein, such as chicken or fish, and healthy carbohydrates, such as brown rice, beans or pulses. Olive or rapeseed oil are also allowed as these are full of essential fatty acid.
The combination of a low-calorie and low-fat diet will help you lose weight and because the exercise is broken up into little chunks, there's no excuse not to fit it into your day.
