A recent study says that a sugary drink along with a protein-rich meal can change food preferences, negatively impact energy balance and result in storing more fat in the body.
Dr Shanon Casperson from USDA-Agricultural Research Service Grand Forks Human Nutrition Research Center, USA, the lead author of the study explained: “We discovered that a third of the extra calories obtained via the sugary drinks weren’t expended, fats metabolism was diminished, and it burn much less energy to metabolize the meals. This reduced metabolic efficiency may cause the body to store more fat.”
The researchers discovered that the intake of a sugar-sweetened drink reduced fat oxidation, which initiates the breakdown of fat molecules, after a meal by means of 8 percent. If a sugary drink was once consumed with a 15% protein meal, fat oxidation reduced by means of 7.2g on average.
Fat oxidation was reduced by 7.2g on average when a 15% protein meal consumed with a sugary drink. Fat oxidation reduced to 12.6 while a 30% protein meal with a sugar-sweetened drink.
Dr. Casperson mentioned: “We were amazed by way of the have an effect on that the sugar-sweetened drinks had on metabolism when they had been combined with better-protein meals. This combination also increased thestudy subjects’ desire to consume savory and salty foods for four hours after eating.”
About 27 healthy-weight adults (13 male, 14 female) aged 23 years old were recruited by the researchers. Participants received two 15% protein containing food for breakfast and lunch, after an overnight fast on one visit and two 30% protein meals after an overnight quick on the other visit. The increase in protein was counterbalanced by means of a reduction in carbohydrates. All meals have been composed of the similar foods they usually offered 17g of fat and 500 kcals. Participants had a sugar-sweetened drink with one of the meals and a non-sugar sweetened drink with the other meal.
The researchers utilized a room calorimeter, a 25m3 furnished chamber that can measure movement, carbon dioxide, oxygen, stress and temperature to evaluate how dietary alterations had impact on energy expenditure and the way in which vitamins and minerals had been processed by the body. Researchers can check the number of grams of carbohydrate, protein and fat the participants were using and how many calories were burnt every minute. Participants stayed within the room in the course of every study visit.
Dr. Casperson remarked that “our results advise that having a sugar-sweetened drink with a meal affects either side of the energy balance equation. On the consumption side, the extra energy from the drink didn’t make men and women feel sated. On the expenditure side, the extra energy weren’t expended and fats oxidation was decreased. The findings offer further insight into the possible role of sugar-sweetened drinks — the biggest single source of sugar in the American diet in obesity and weight gain.”
Dietary changes were assessed only for a short time and caution must be used when inferring the study data to dietary modifications over longer duration. Since this study was in healthy-weight adults only, the authors also caution that overweight individuals may react in a different way to dietary changes.
