For this week's episode of Food Unwrapped, Jimmy Doherty, Kate Quilton and Matt Tebbutt look into the science behind slimming. It's a topic particularly in focus at this time of year as we're encouraged to get in shape for summer holidays. They speak to 'super-slimmers' about their diet tips, and look for scientific evidence to back up these weigh loss methods. They also look into popular foods supposed to aid in slimming, including apple cider vinegar and miso soup.
