Yes of course you can. You can opt for any diet you like, but the question is will it work? I have not tried a detox diet so I don't know. But I know a few people who have tried this and they say that they have seen positive results. But I remain quite skeptical and I don't think that it is possible to lose any weight in two weeks. You can of course go on a detox diet and get rid of unwanted and unhealthy toxins from the body. But this depends on whether or not you stick to your detox diet. It involves eating a lot of healthy food items that don't taste very good. Are you up for it?
