High-protein foods such as steak, grilled chicken, boiled eggs, processed nuts, and other high-protein intakes are often to be the choice when men want to build muscle mass or dieting. Unfortunately, the benefits of a high-protein diet can actually be “smashed” by high-sugar drinks, such as sodas, sweet tea, packaged sweet drinks, and even fruit juice.
This is why you should not eat sweet drinks along with protein-rich foods. Drinks that contain high sugar can disrupt the body’s metabolism (thus making the body fat fast) when paired with high-protein foods, a study showed.
A new study published in the journal BMC Nutrition was originally set out from the question “What happens when you combine healthy foods and unhealthy beverages? Are the negative effects greater than positive effects?”
In the study, researchers discovered what happens when you mix something sweet with a protein-rich diet. The result is body fattening.
The researchers collected 27 young adults with healthy weight and involved them in two 24-hour studies. After a night of fasting, participants were given two portions of food each containing 15 percent protein and 30 percent protein.
Each food contains 500 calories and 17 grams of fat, and one serving is paired with a sweet drink.
During the study, the study participants were placed in a calorimeter chamber, a room that could measure activity, oxygen, carbon dioxide, temperature, and pressure to determine energy expenditure and nutrient processing by the body.
The results show, when participants are given a serving of food with a sweet drink, a decrease in fat oxidation in the body, which is an important process in fat burning.
“We were surprised by the effect of the sweet drink on metabolism when paired with high-protein foods,” said study leader Shanon Casperson, Ph.D., research biologist at the Center for Human Nutrition Research at Grand Forks USA. “This combination also increases the desire to eat savory and salty foods for four hours after eating.”
The study shows that pairing sugary drinks with high-protein foods can affect energy intake and balance.
“On the side of the intake, the extra energy from the sweet drinks does not make people feel fuller,” says Casperson. “On the expenditure side, extra calories from sugary beverages are not easily released by the body and actually cause a decrease in fat burning.”
