FAST 5:2 / Management

The LighterLife 5:2 Fast Plan is a great way to lose weight or manage a healthy weight. If you are close to the weight you'd like to reach it could be the perfect time to start the 5:2 Fast Plan. Replace your conventional food with 4 of our tasty Foodpacks on days you choose to Fast and get all the nutrition you need in around 600 Calories (you can’t do that with ordinary food). There is no weighing, no shopping, no counting - it is so easy, especially if you use Foodpacks and meal replacements like LighterLife FastPots on non-Fast days too as convenient, nutritious meal options!

Keeping your weight stable is an active, rather than a passive skill; just wanting or hoping to stay thin will not achieve it. Independent research shows that people who attend management groups regularly, and replace some meals with Foodpacks or meal replacements do better at keeping their weight off long term. In group you'll develop your skills further, so you can maintain your new, healthier weight for the long term and be the person you want to be.

Popular Fast days are Monday and Thursday as it pays back for a heavy weekend and then saves up for the next one. You can Fast more days a week if you want.  Fast groups have up to eleven others in the group all using the same 5:2 Fast plan (we don’t mix men and women).  There, using CBT, you can develop the tools to understand your relationship with food and drink.


  • Up to 1/3 of your RDA’s of vitamins and minerals in each pack – around 600kcal a Fast day
  • You’ll need 32 Foodpacks or Meal Replacements for 4 weeks (with more for other days or if you do more than 2 Fast days a week)
  • Unique LighterLife CBT counselling content (with group subscription)
  • Access to online support tools and community, mentoring emails and tips by text
  • Eat normally for the other days of the week

Denise’s Story

Denise lost 2st* with LighterLife before her wedding in 2013. Here she shares how her attitude to food changed...

Denise says: "I lost weight for my wedding in 2013, and chose LighterLife because of the group work. I'd swapped drinking too much for eating too much. What I quickly realised through the LighterLife group work was that I often listened to the Child's voice inside my head: the rebel that says 'Go on, you deserve it.' I was ignoring my rational, Adult voice."
