Documenting facts about obesity!

Chris Bavin is so full of character he was born to be on TV – this was underlined by the announcement that he was to join Mary Berry as co-judge on her new BBC series.

After a TV production company first stumbled across him in 2011, he has gone from strength to strength and is co-presenter of BBC1's hugely successful series Eat Well For Less? with Gregg Wallace. The show has had incredible ratings and the accompanying book is a best seller.

Chris is back with the new season of 'The Truth About Obesity', which airs on Sony BBC Earth. The series looks at groundbreaking new treatments: from faecal transplants to the hunger-hormone injection that might eliminate obesity forever. And a time-travelling experiment reveals how we're fatter than we were in the '70s – despite eating fewer calories and doing the same amount of exercise. It showcases the real reasons we get fat, how it affects our bodies, and how you can stop it happening to you.

"The programme is a one-hour documentary which is looking about why as a nation we are gaining weight, what can we do about it and what is science doing to help combat it," he shares.

"The audience will be surprised with some of the science involved as they would be reasons as to why we are gaining weight and also they would be amazed by some of the scientific development that can hopefully help fight the obesity in the future."

Regarding the science that is involved in the show, he says, "We look at genetics, how genes are playing a role in weight gain. We will also learn about some of the treatments available to help fight it, surgeries, gastric valves and the other things that are related to science and the surgical procedures that are used. People think hormones play a new part in it so we are looking at this issue and we will also a few things that can happen without surgery."

In the show gets tests done on himself. Using his body to perform certain test he says, "I did not take any medicine, but I did a test where I had to eat the same meal in the evening and morning and then test my blood sugar levels to see how my body reacts to it. I swallowed a small internal camera that looks at my gut."

Why should one watch the show? He says: "It is a very interesting show I people will surely learn something from this. It has been s shot in the UK and in certain universities and hospitals and has a lot of doctors and professors involved."
