It's hardly rocket science - we get fat watching Russell Grant!

Apparently we all gain between two and four pounds in weight - just because it's winter. It's because we FEEL we should eat more to stay warm, we always feel hungry because our natural levels of melatonin decline. We develop a taste for fatty food in autumn, plus we do tend to sit in front of the telly more.

All I know is that I do indeed put on weight in winter, and heartily dislike going out for a walk or a bike ride when it's hailing and snowing.

But mostly I blame Downton Abbey, Spooks (RIP), X Factor and Strictly Come Dancing.
