I don’t personally think eating out is a problem per se. I really believe the obesity crisis is down to sugar and lack of exercise. In the past it was common for working class families to have fried egg, sausage and chips for tea and they weren’t fat. These days we eat so much processed foods and a lot of it has added sugar.
I make milkshakes at home sometimes. I blend together a cup of ice cream, cup of milk and some fruit and it tastes lovely, but most recipes will say add sugar and most bought milkshakes will be full of sugar. You don’t need it though as there is already a lot of sugar in the ice cream. Why are you adding sugar to sugar?
If people are worried about obesity then cooking at home is the best thing you can do because you know exactly what you are eating then. You can make good, filling foods with no added sugar. If your main meals are pretty much sugar free (there’s a little in bread but not much), then even if you eat one sugary snack every day, you’ll be well under your sugar allowance for the day.
The problem is that kids are having sugary cereal and sugary drinks for breakfast, sugary yoghurts, sugary drinks, sugary puddings for lunch and then something processed and full of sugar for dinner and that’s before all the sugary snacks they have.
A lot of people are quite confused about what is and isn’t healthy. They think a shop bought cereal bar is healthier than a homemade ham sandwich or that pasta in shop bought tomato sauce is healthier than than sausage, peas and chips for dinner.
