Episode 8

Care worker Deana road tests the reboot of the Slimfast diet. Can this restrictive diet cure her sweet tooth for good? We also catch up with Jax, who tested the Weightwatchers range in 2017 and lost an impressive 13 pounds. Two years on, has she continued her weight loss journey? Sian Williams joins dietician Linia Patel to find out whether crisps can ever be part of a diet, and Dr Ranj looks at DNA kits which claim to create personalised diet plans based on our genetic codes.
