No it does not.
Raspberry ketones may be helpful in losing weight as per some scientific studies.
But the weight loss is usually gradual usually one stone in 6 mnoths or so.
Diet and exercise should be the mainstay to achieve this weight loss.
Hence, any website claiming 2 stones weight loss in 5 wks is not substantiated by any clinical studies.
