Teaching need not always be stressful, but stress can be a factor in weight gain or loss. There are plenty of other explanations.
The type of English teaching done, the environment, the relationships with colleagues and the nature of the employer, may also cause problems.

A lack of a supportive environment could mean that FTs feel isolated. Isolation can produce many setbacks for FTs in a strange environment. For those FTs who don’t speak the language or are experiencing severe culture shock, there may be an element of ‘comfort’ eating. Sometimes these emotional responses to the immediate environment can produce a greater reliance on alcohol and also a conscious choice in eating food that is familiar. Research indicates that in China it is bacteria that affects weight. No surprise there.

Well-written enough post as usual, CL. Laudable enough sentiments and excuses for inadequates. However, understanding and excusing old 'fat guts' isn't going to help him.

Now to be overweight looks disgusting-No? To be overweight is disgusting-Yes? All this pussy footing around telling Fatso, it's okay ,we understand you are stressed, and that is why you need your comfort food. Actually many overweights used to be smokers and they had to replace their comfort fags with comfort food- the problem with that is that that extra weight is going to get you to the Exeter Crematorium a lot quicker than the time you would have arrived if you'd continued smoking hahaha.

Right, my good advice to fatso- many of us are stressed out, and that's bad enough without being obese to boot. You must stop feeding your face- you must stop feeling sorry for yourself- you must become a stressed-out slim person of good character and strong purpose. Then..then, those tasty Chinese girls may be a knocking on your door- and then- then, you will feel less stressed out.

It doesn't matter about exercise to start with; especially exercising your jaw bones, just stick to 1000 calories a day- any fewer than 800 not good- and more that 1500 will send you up Fat Creek without a paddle.

Put that tape measure around your waste tonight(above the navel) and if you measure more that 37 inches you are in serious trouble- you are medically Centrally Obese- stop farting about and do something about it, please.
