All the high Street shops near me have shut down, yet more and more cafés and restaurants and fast food places keep opening. In an area of less than 1sq mile, I can visit Tim Hortons, two mcdonalds, a kfc, a burger King, 3 Costa coffees, a Starbucks, plus maybe 10 other chain restaurants like Ask. All the drive-thrus have a constant steady queue of customers. You can easily use a day's calorie allowance in one meal, or even in a snack. My SIL gained a stone when Starbucks opened in her town - took her a while to figure out her new weekday Starbucks habit was working out at about 500 calories on just coffee.
Our culture has changed. I think back to my childhood, the idea of my mum going out to meet friends for coffee or brunch was unheard of. You had your cup of instant nescafe and talked to your mates in your own kitchen, saving yourself money and calories. You were more likely to walk places as it was uncommon to have more than one car per household (in my area), everyone walked to school, not drove.
I look back at my childhood diet and it was largely processed shite with minimal fruit or veg. The reason why we weren't all fat then is because we were habitually more active, and didn't eat out at restaurants/cafés as much.
