In the heart of Birmingham, doctors Chris and Xand van Tulleken have set up a unique centre for science. But theirs is no ordinary lab because inside it is crammed with 30 pairs of identical twins! Thanks to their matching DNA, identical twins are the perfect candidates for scientific comparison.

Chris and Xand use this principle in The Twinstitute to put contrasting health theories to the test. Pairs of twins are split into two groups and each challenged to carry out a task. The results, from diet tips to health tricks, reveal ways we could all make lifestyle improvements. This is New Year New You tested scientifically!
