Don't waste your time! Everyone is different. Body types are different. Thyroids operate differently in different people. Metabolisms are different and function differently in different people.
To make a sweeping statement such as you did; a fat person is ALWAYS hungry -- is simply, factually incorrect.
The bottom line:
Another person's weight is NONE OF YOUR BUSINESS, nor is it the BUSINESS OF THE FEDERAL GOVERNMENT.
I provided 6 different medical studies that support my statment. Can you provide any sources? If I am wrong, then why do every drug, and every medical proceedure target the appetite mechanism? If I am wrong, why does every recognized diet stress the fact that you "won't feel hungry"? Sources please, personal opinions don't count.
BTW, I do agree with your last statement, in that a person's body weight is no one else's business, nor is it the busines of the Federal Gov't.
