A 46-year-old managing editor from London, Adam Juniper, has lost seven stone in seven months by cutting out unhealthy snacks and eating rice cakes to curb his cravings, rather than using weight-loss injections. He says the transformation has also revived his sex life, which had suffered as his weight increased, and boosted his confidence after years of struggling with basic tasks like climbing stairs.

Juniper went from 19st 6lbs at his heaviest to 11st 8lbs by replacing snacks such as cookies, chocolate bars and burgers with rice cakes, which average around 35 calories each, often combined with fruit such as apples to increase food volume without adding calories. He now eats about ten rice cakes a day. Previous attempts to lose weight, including calorie counting and eating only fruit, had failed to produce lasting results, and he traces his weight gain to giving up a seven-mile daily cycle commute after moving to London in 2015 and continuing to snack heavily.
