It is ironical indeed for someone to kick-start his day with a pair of orange juice and burger, having the notion of being fully energised for the day’s work, whereas he has just crippled his chances of having a productive day, a new study has suggested.
The researchers from the USDA’s nutrition research centre warned the populace to desist from such pair of meal, noting that adding a sugary drink to a protein-packed meal makes you more tired and prone to weight gain.
The team studied a group of 27 adults- 13 males and 14 females, with a healthy weight and average age of 23. The participants made two 24-hour study visits, receiving two meals with 15 percent protein (breakfast and lunch) after not eating anything overnight on the first visit. On the second visit they got two meals with 30 percent protein following the overnight fast.
The findings reported on Daily Mail Online revealed that there In the second visit, the protein increase was counteracted by a decrease in carbohydrates meals were made with the same foods, and had 17g of fat and 500 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.
The result showed that the addition of sugary drink to a heavy protein food decreased people’s ability to burn fat.
Fat oxidation kick-starts the breakdown of fat molecules and provides people with long-term energy.
According to the lead author of the study, Dr Shanon Casperson : ‘We found that about a third of the additional calories provided by the sugar-sweetened drinks were not expended, fat metabolism was reduced, and it took less energy to metabolize the meals. This decreased metabolic efficiency may “prime” the body to store more fat.’
All meals were made with the same foods, and had 17g of fat and 500 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.
‘We were surprised by the impact that the sugar-sweetened drinks had on metabolism when they were paired with higher-protein meals,’ Dr Casperson said.
