Study Highlights Impact of Eliminating Ultra-Processed Foods on Weight Loss

A recent study indicates that avoiding a specific type of food can nearly double the results of weight loss efforts. Published on August 4 in the journal Nature Medicine, it reveals that overweight adults who stopped consuming ultra-processed foods (UPFs) lost almost twice the weight over two months compared to those who didn’t.

Ultra-processed foods entail items like frozen meals, sodas, potato chips, and packaged cookies. However, there’s a growing concern that some foods marketed as “healthy” might also fall into this category.

Dr. Jeffrey Craft, an obesity surgeon at Hackensack Meridian Palisades Medical Center in New Jersey, mentioned his own experiences, explaining that processed foods undergo various modifications to ensure they last longer on shelves. He remarked, “They don’t help to fulfill our natural feeling of fullness and are often mixed with unhealthy ingredients like high fructose corn syrup and hydrogenated oils,” emphasizing their negative effects.

Ashley Carnahan, a registered dietitian at Henry Ford Health in Detroit, noted that switching to whole foods typically keeps people feeling satisfied longer due to higher fiber and protein levels. Even some protein bars can be heavily processed, but she believes it’s acceptable to indulge occasionally, suggesting that boiled eggs are a great source of complete protein.

“For those pressed for time in meal preparation, focus on whole foods like apples, bananas, carrot sticks, nuts, and natural peanut butter,” Carnahan advised. These foods are convenient and require minimal planning. She encourages gradually increasing the intake of fruits and vegetables, aiming for about three cups of vegetables and two cups of fruit daily to support a nutritious diet.

Carnahan emphasized that consumers should pay close attention to food labels, particularly the amounts of sugar and sodium. “Generally, lower is better,” she said.

Dr. Kraft also suggested that shoppers should prioritize the perimeter of grocery stores, where fresh produce is typically found. “This area usually contains the healthiest options, which tend to spoil sooner,” he explained.

Lastly, Kraft advised his weight loss surgery patients to start their day with low-calorie protein shakes. But he warned, “Remember, if you’re not getting enough sleep, you might be facing undiagnosed sleep apnea, which will hinder your weight loss journey.”
