A recent study explores how switching to unprocessed foods changes the way we eat and how many calories we consume. Researchers found that when people ate only whole foods, they consumed over 50 percent more food by weight compared to those eating ultra-processed meals. Despite eating more volume, their daily intake was actually about 330 calories lower on average.

The study suggests that on a whole-food diet, people naturally choose nutrient-rich fruits and vegetables. This helps them get essential micronutrients, like vitamins and minerals, while avoiding foods that are packed with calories.

In contrast, ultra-processed foods are often high in both energy and micronutrients at the same time. The research indicates this combination can disrupt the body's natural balance and lead people to eat too many calories. The lead author noted that the findings prove people make better eating choices when food is served in its natural state.
