The health watchdog for England and Wales is insisting its plan to pay for overweight and obese people to go to slimming clubs will save the NHS money.
NICE says the classes, which could cost up to one hundred pounds per person; won't amount to as much as treatment of people for weight-related issues.
But some campaigners don't think the NHS can afford the plan in the short term.
Gaynor Burton is from Christian fitness organisation Fit Fish and told Premier's News Hour why she thinks the plan may be a little too simplistic.
