There are many things and that's why there is no one surefire solution. I will say diets are basically simple for those with no pre existing condition. Burn more calories than one takes in. It can be done with diet, exercise and/or BOTH.
Processed food ingredients-oh boy. It's not that they are processed it is THE ingredients. One 'ingredient' are the preservatives. If preservatives preserve the food what will preservatives do with fat cells/content in the body? Also a lot athletes complain about cross contamination on foods and supplements causing them to come up positive on a drug test. What do those contaminants do to the non athlete?
My guess fat content or fat type could theoretically cause blood sugar to rise in Turkey dogs.
I once arrested a man and when booking him in, he weighed in at 477 pounds. Obviously, he was not a cat burglar. On the other side of the coin, I also arrested a female drug addict that probably should have been dead. She was 5'3" and weighed in at 77 pounds. She told me that she had not eaten a meal for almost two weeks. I told her that I would make sure that she was fed as soon as we were done with the booking process. I kept my promise.
It's called spare time in front of a tv or computer screen. Even worse the current "fitness" culture has produced a generation of worker outers that now have become addicted to having a tv and/or music with them the entire workout via ipods and treadmill tvs.
Unmotivated prima donnas if you ask me.
Well Philly, twice in my life I gained a great deal of weight, partially because of incredible stress/PTSD, and partially because I require only half as much food as the average person. Was I an undisciplined, unmotivated, weak person? Hell no, I was
dealing with crap that would have killed most peeps, hiding behind a wall of fat kept me alive, until I was able to face my pain, and shed the weight. Who are we to judge what pain lies behind the eyes of another person, just because we don't have a real problem with weight?
