Pounds aren't everything. Although it is important to lose weight if obese, an over-reliance on fatty meats will take a long-term toll on these individual, as their risk of colon and (in men) prostate cancer increases significantly, according to studies. It is foolhardy to make meats such an intensive part of one's diet.
I agree carbs are bad, mainly because they are processed, and the human body is not designed to process them. But I know many Atkins afficianados who suck down the meats while avoiding vegetables, as well as barbs...recipe for long-term health disaster.
