In many cases of obesity it is a sign of the times. There are exceptions were a medical condition is responsible and no amount of dieting helps. I was talking to my daughter recently while we were looking through old photo,s from the 60s & 70s and we were commenting how thin everyone seemed to be by comparison to now. No 24 hour television to distract us, no computers and mobile phones, just as well as we would,nt have had the time. Back then we did not have multi-packs of crisps, microwave meals, BOGOFs pizza deliveries, and lots of us did not even own a fridge then let alone a freezer to fill up with tempting foods on hand. A takeaway for us in those days was fish & chips and not on a regular basis either. We did a lot more manual work in the form of housework, no tumble dryer then...back and forth to the washing line praying for it to dry, pushing a big pram with with one baby inside, one on a seat on top and another one holding on to the pram. Nappies then we're terry which had to be washed ...disposables just coming in but classed as luxuries for travelling. Cleaning out the one coal fire which was total heating for the compete house and then on hands and knees washing the floors. Just a few of the reasons we were slimmer then was the sign of the times as it was for us. We could choose to be working mothers or not then. A lot of people now have no option but to work and at the end of the day probably do rely more on convenience foods or takeaways as simply too tired to cook from scratch when getting home. Plus I think we had more small independent shops rather than massive supermarkets like now, I remember a very small Budgens and a small Tesco,s where I used to live, and nothing like the quantities of products they have these days. I think complete change of lifestyle and not just altering your diet has to be the way forward if a person is determined enough to want to change and not everyone does.
