A company in the United States is offering many overweight people some hope. They have started performing genetic testing to determine why some people become obese. The theory rests on the idea that despite living identical lives, one person may be overweight while another remains a healthy weight. Thus, lifestyle is not the only determinant in weight loss or gain. According to their research, they have discovered some genetic markers that may make some people more sensitive to fats and others more resistant to diet and exercise while some burn carbohydrates at different rates.
