Researchers found that eating a protein-packed meal with a sugary drink on the side decreased fat oxidation by eight per cent, re-potted Daily Mail. For instance, having a glass of juice with your chicken salad might make you feel more tired and likely to gain weight, a new study claims. Fat oxidation starts the breakdown of fat molecules providing people with long lasting energy. Researchers chose to study this so they could analyse how sugar sweetened drink im-pact the way the body bums fat after a meal. Currently sugary drinks, such as sodas and juices are the biggest single source of sugar in our average diet. Dr Shanon Casperson, lead author of the study, stated, “We found that about a third of the additional calories provided by the sugar sweetened drink were not expended, fat metabolism was reduced, and it took less en-ergy to metabolise the meals. This decreased metabolic efficiency may ‘prime’ the body to store more fat.”
The research team recruited adults, all of considered to have a healthy weight and were on avenge 23 years old. The participants made two 24-hour study visits, receiving two meals with 15% protein (breakfast and lunch) after not eating anything overnight on the first visit. On the second visit they got two meals with 3o% protein following the overnight fast. In the second visit, the protein increase was counteracted by a decrease in carbohydrates. All meals were made with the same foods, and had 17g of fat and 50o calories. Participants consumed a sugar-sweetened drink with one of the two meals on each visit, and a non-sugar sweetened drink with the other.
During this process all movement, oxygen, carbon dioxide, temperature and pressure, were measured of all participants in a room calorimeter chamber to monitor how much energy each participant was using. This showed the way dietary changes affected energy expenditure and how nutrients were processed in the body. By confining the participants in the room calorimeter, researchers determine how many grams of carbohydrates, proteins and fats they burned in a minute. Participants stayed in the room for the entirety of the visits. They found that adding a sugary drink decreased people’s ability to burn fat.
If the sugary drink was had while the participant had a meal with 15% protein, fax oxidation decreased, on average, by an avenge 7.2g. If the drink was consumed with a 3o% protein meal, it decreased by 12.6g on average. The sugar sweetened drink did increase the amount of energy used to metabolise the meal. “We were surprised by the impact that the sugar sweetened drinks had on metabolism when they were paired with higher-protein meals,” Dr Casperson confessed. The study also found that the participants craved savory and salty foods for about four hours after eating the meals that were paired with sugar-packed drinks. “Findings suggest that having a sugar-sweetened drink with a meal impacts both sides of the energy-balance equation. The results plays potential role of sugar sweetened drinks the largest single source of sugar in the American diet – in weight gain and obesity.”
