There are a lot of excuses that are thrown out for not losing weight. Someone has a thyroid issue, another has a bad metabolism, yet another has bad genes. New research is showing the ethnicity may be a new reason that you are not dropping those pounds like you wanted to.
Researchers at the University of Pittsburgh School of Medicine have found that African-American women need to eat less calories and work out a lot more in order to lose the same amount of weight as white women. This is where the metabolism ties in. The researchers believe that African-American women have a slower natural metabolism than Caucasian women do. When on the same diet it was found that African-American women lost an average of 7 pounds less than white women did.
During the study, the researchers looked at a number of different physical factors including calorie intake, how energy was expended, weight changes in the body, and the amount of physical activity that the women got per day. They studied 39 extremely obese African-American women and 66 Caucasian women. All of the participants were in a weight loss program that lasted six months.
They found that even though the African-American women ate the same amount of calories and worked out just as much, they were still expending less energy during the day and had a lower resting metabolic rate. Both of these can contribute to fat build-up. One of the doctors on the research team stated that in order for the African-American women to keep up with the weight loss of the Caucasian women they needed to eat a lot less and workout a lot harder because their metabolism was slower.
