LighterLife research highlights

As well as being an effective weight loss and maintenance programme for individuals in good health, LighterLife’s Total very-low-calorie (VLCD) has been shown to be equally effective for those who face additional barriers in achieving weight loss or for whom ‘traditional’ weight-loss methods are largely ineffective, including those with type 2 diabetes and polycystic ovary syndrome (PCOS). It may also be a viable alternative to bariatric surgery.
