In our society, if you don't eat organic meat, dairy and produce you WILL get fat. Non-organic meat contains steroids and hormones that cause you to gain weight. That's how they plump up the livestock afterall! Those hormones don't go away magically just because afterward it is sold as meat. I have questions about non-organic dairy also. I was reading about how you shouldn't feed milk to cats otherwise they'll get worms...this was in a pet care book! So, if the cat gets parasites from milk, why wouldn't humans? I'm not a vet or a physician but we're all still mammals here.
Anyway, although it sounds disgusting and there is a stigma attached to the idea, most humans have intestinal parasites they don't even know about! I have read that colon cleansing followed with pro-biotic intake is important to losing weight. It makes sense, because if you have little critters living in your stomach, they get to the food before you do, leaving you constanting hungry and undernourished. I have been eating alot of garlic and other spices lately and I have lost 4 inches around my waist in the last 2 months. You can buy serious colon cleansing products at the health food store for this if you don't want to walk around smelling like garlic. They do sell garlic pills also.
Also, I think you really have to keep up with the exercise and cut back on sugar. Eating too much sugar several times a day causes insulin release each time. If you are sensitive to insulin then you will gain weight. And even if you're not, sugar still isn't congruent to a good diet and exercise program. With exercise, even brisk, or comparatively so, walking helps. You'll find yourself speeding up and exerting more energy in a week or so of daily walking. However, it has to be for at least 30 minutes EVERDAY when you first start out. You must kick start your body into knowing that you mean business, otherwise it will quickly recover thinking it was a one time thing.
I hope some or all of this helps, and God bless!
