In a television first, Fat Family Tree sets out to prove that unlocking the secrets of a fat family’s genes can help provide the answer to their lifelong weight problems. Presented by Dr Dawn Harper (Embarrassing Bodies), Fat Family Tree uses cutting edge genetics to decode the genes of an overweight family for whom all other attempts to shed the pounds have not worked. Discovering how the family’s genes have put them at risk of excessive weight gain is the first step to devising a diet to help them beat their genes. Based on the latest science, the programme’s “gene-busting” diet also promises fail safe diet tips that could help all of us lose weight.
