A lot of those "fat chicks" have a real medical condition called PCOS which causes infertility and guess which diet they use to get pregnant. Yep, that's right they start on Atkins and most women who had no periods or were not ovulating get regulated usually within the first month. I know of quite a few women who got pregnant after a few months of Atkins. These are women who spent thousands and thousands of dollars on infertility drugs.
This study is full of crap. The truth is once a person gets out of the carb induced coma and starts eating more meat and fat their ability to think clearly goes up exponentially. The fact that women lose weight is only one reason some are low carbing. I also know of many diabetics who have been able to get off of their diabetes meds just by low carbing.
Actually now that you mention it.. my sister-in-law on Atkins is having her 4th baby at 38.
I'm a man who weighs about 200 pounds, has a blood pressure of 120/80, and slightly elevated cholesterol. Growing up, I could eat a box of cupcakes a day (no exaggeration -- 12 cupcakes a day) witout gaining weight and I can still eat quite a bit of junk food and processed carbs. I never really had any sort of attention-deficit disorder, either. My wife has PCOS and can eat substantially less than I do and still gain weight on a traditional diet. Another friend was tested and found out that he'll gain weight if he eats more than 900 calories a day so he opted for a gastric bypass (which I'm not advocating). I know by comparing what I eat and what they eat and by what I weigh and what they weigh that "metabolism" is a very real issue when it comes to how people react to food or gain weight.
The people who complain about "fat chicks" and think that "eat less" is a winning diet strategy are usually people like me who can eat just about anything they want without gaining weight. It's easy for me to diet because I can also just skip meals or eat less because I usually don't suffer the blood sugar ups and downs that create hunger (though I can feel how strong they are when I do have them). Not everyone is the same. They key is to identify your particular problem and find an eating strategy that works for you, much as people might try different anti-histamines or pain medication to find the one that works best for their metabolism. One size does not fit all.
I agree with you. Polycystic Ovary disease......is a bad deal but the weight loss is key to fertility.
