Interesting topic.
Eat less, move more, repeat. That is the KISS principle/solution.
However it's not always that simple.
My DH is one of those skinny guys who could have the worst diet in the world, but as long as he's working doesn't gain an ounce. Me on the other hand, can't do that.
My mother has spent most of her adult life being morbidly obese. She has lost weight, with WW and a few years ago when she was diagnosed as non insulin dependent diabetic she lost weight. She was actually starting to look good. But, she has this mental thing, she just can't live without that pshycological fat. For some reason her fat is her insulation from the world. She got all the way down to a size 18 and my sisters and I were so proud of her, but it freaked her out! She could see her collar bone, and her hands were just so bony and on and on. Needless to say, she gained back about 75 pounds. I did see at Christmas, she's lost some again, but she doesn't look good. I think the lifetime of obesity is finally taking it's toll.
And since I'm in the mood to make a long post.....I work for a veterinarian and we deal with "fat" pets all the time. Older dogs, overweight, arthritis, etc. When we tell owners dog/cat needs to lose weight. Owners freak out.
OMG, feed the dog/cat less?!?! Actually take the pet for a daily walk? We CAN'T do that! Well ok, then spend the money for the pain meds. OMG! That stuff is expensive! Yeah, it is.
Because of my mothers struggles, my sisters and I try very hard to keep our weight and diet reasonable. We don't want to be diabetic, have gall bladder surgery, heart surgery, like Mom. It's not an easy task. We all struggle, we talk to each other, and thankfully, even thought we don't do it all the way it should be done, we are doing better than Mom.
For those of us who struggle with our weight and food issues, I really feel it is no different than those who battle alcohol, drugs, depression, and many other issues.
It can be made to seem simple, but it really isn't.
Anyway, thanks for listening!
