Why are some people microdosing weight loss drugs?

Some people are injecting a fraction of the standard dose of weight loss drugs and hoping to still receive the benefits, but many are doing so without any medical oversight and there could be risks. Makers of the drugs say they don't condone people modifying how they use their products. Health journalist Katie Silver speaks to Claudia Hammond about why some people are choosing to microdose these weight loss drugs. With wildfires spreading across Western Europe, North Africa and Canada, Claudia is joined by BBC Health Reporter Laura Foster to discuss recent studies into the impacts wildfires can have on our health. Claudia and Laura also talk about new research into fertility and pregnancy loss as well as asking, are we consuming too much protein? And it is increasingly clear that multiple sclerosis (MS) is linked to Epstein-Barr virus infections, but can we use that knowledge to stop the progression of MS? Claudia speaks with Michael Levy, associate professor at Harvard Medical School and neuroimmunologist at the Massachusetts General Hospital, to understand if viral treatments could halt this disease and why this common virus can cause such severe immune responses in a few individuals.
