So many of you seem to think you have the answer, and in theory you are right eat less move more, and cut down on sugar and fat etc... But it really isn't that easy, I can honestly say I have tried everything short of surgery, Been a size 10 and a size 26, had hypnotherapy, hypnogastric band sessions, slimming clubs, low fat, atkins, keto, been a gym regular, swimming 3-5 times a week, walked miles, fasted, low cal meal replacements, diet pills that were similar to amphetamines, and prostate that have me horrendous but problems and at time lost 4-5 stone before something clicks and I stop like an alcoholic and go back to the foods that poison me. Every time getting fatter yet I look back to when I was young and see by today's standards I was a healthy weight for my height, very toned and active, but guess what in the 1970s size 16 was considered gross so the cycle of failure began.
Fashion clothes were hard to find even in a size 14, at least normal has adjusted upwards slightly and although bmi isn't the best measure being able to measure body fat percentage is quite a good guide.
I do believe that the car is one of the biggest problems, people just don't walk they are it as "exercise" not the normal way to get about, over protective adults drive children from a to b,
My second culprit is decades of marketing, the adverts show idealised humans indulging in the food and drink that will change them into something a million miles from the marketing.
Thirdly the want it now culture... That's the reason for fast food, microwave meals, takeaways and deliveries, no one waits, they say they have busy lives, but are they as busy as years ago, no, but they have to be seen as busy, because that has come to be a measure of success. A full diary, constant contact means no time to cook. I know if couples who have ditched having a kitchen to fit in a home gym, but also I know if many who despite watching tv chefs don't cook. Guess what fear of it not turning out perfectly stops them. Somewhere in the last 50 years or so we became frightened to fail, we have to be perfect so better not to try.
Last and this is going to be contentious the way children seem to become little tyrants whose every whim must be obeyed. The screaming tantrums when parents try to get them to go past McDonalds, the excuses when meals are what the child chooses because otherwise he or she won't eat, guess what, a child will only choose the stuff they like or see their favourite character advertising. Sometimes the easy options are not the right way, and I understand that after a long day at work arguing about a few peas and carrots is really difficult, and food equals love, it's deeply connected to ideas of home and nurture.
