The question is: will this measure have any effect on the national obesity problem, not how each of us individually respond to it - and, as far as I can see, it is another of those pointless measures that governments award themselves brownie points ( 250 calories a point) for and are easy to blow their trumpets about but are purely window dressing.
Go around any town, any village, sometimes, and there will be burger joints, chicken takeaways, kebab shops, Indian and Chinese takeaways, non-chain pizza outlets, where every day millions of people go to get their daily take away, eaten in front of the tv and drunk with a can of beer or they will go to the supermarket and buy a pizza, dough balls and some doughnuts to be eaten as above.
This is how people put on weight, not by going out on occasion to a Hungry Horse. Harvester, Beefeater, Nandos, or the like and having a good meal.
We live in a rural area and eat out mainly at local pubs serving basic pub food, to really good gastropubs. None of them will have calorie counts on the menu.
This is the eating equivalent of green washing. Should we call it fat washing?
