Drinking a soda with your fried chicken or burger can really spark your body to add on more pounds, a new study in the journal BMC Nutrition suggests.
Adults who had a sweetened drink with a high-protein meal stored more unused fat, compared to others who had a sugar-free drink, laboratory tests discovered.
For the study, 27 healthy weight adults were put in a sealed laboratory that tracked how much oxygen was inhaled and carbon dioxide was exhaled. Samples of urine was collected as well.
Participants spent two days in the lab. One day they consumed two meals containing 15 percent protein, and on the other day they ate two meals with 30 percent protein.
“If we are adding extra carbohydrates on top of what’s already in a meal, that will definitely have an effect on the body being able to use fat as an energy source, and it will more than likely go into energy storage,” said lead researcher Shanon Casperson. She’s a research biologist with the U.S. Department of Agriculture.
This makes perfect sense because if you consume too much carbs, your body automatically use it as storage instead of burning it off right away.
Food contains three major types of nutrients — carbohydrates, fats and protein. Casperson and her team wanted to see how extra carbs in the form of a sugary drink would affect metabolism of fats and proteins.
The study found that sugar-sweetened drinks decreased fat oxidation by 8 percent. Fat oxidation is the process that jumpstarts the breakdown of fat molecules.
Also, the sweetened drink consumed with a 15 percent protein meal reduced fat oxidation by an average 7.2 grams, while the same sugary drink with a 30 percent protein meal reduced fat oxidation by 12.6 grams.
I believe that the extra carbs from soda may reduce the body’s need to process dietary fat for energy. The fat that is not burned is then distributed to other areas of the body such as the belly and hips.
Although this is a small study, it just sheds light on how dangerous it is to combine sugary drinks with high protein meals. This will definitely encourage weight gain and slow down the fat burning process. More research still needs to be done to find out why adding extra protein to a meal affects the fat burning process. Until then, I would definitely stay away from sweetened drinks combined with high protein meals to aid weight loss.
