Weight Watchers works best, according to a study published in the Lancet. The RCT recruited overweight and obese adults from primary care practices in the UK, Australia and Germany, randomised to receive a commercial weight loss programme or standard care. Results indicated that "participants in the commercial programme group lost twice as much weight as did those in the standard care group." A recent audit of the UK's weight watchers on prescription programme was similarly positive.
