As an obese person, I am very worried about Boris Johnson& #39;s plan to tackle obesity which I fear will be more about demonising fat people and blaming them if they get Covid than actually helping us. Two things have been essential for me whenever I have managed to lose weight.

The first is being in the best of physical health. A few years ago, it was only after a physical health problem had been identified and dealt with that I managed to lose significant amounts of weight. The second is being in the best of mental health.

So it doesn& #39;t work for GPs to simply tell patients that they are fat. Believe me, they probably already know. If you want to help them lose weight, you& #39;ll need to work out what individual support they need and give it to them.

We need to be very careful that we don& #39;t stigmatise obese people - not just because it is utterly wrong, but also because it will destroy mental health and be completely counter-productive.

And people need to realise that losing a lot of weight takes a long time. A healthy weight loss is 1-2lb per week so the most people might lose in a very good year would be around 5 stone. Any demonising of obese people risks any progress they might be making.
