According to a 2019 Cambridge study, healthy thin people tend to have fewer genetic variants associated with weight gain, stacking the odds in their favor. This offers a major clue as to why do people eat a lot but not gain weight, but genetics are only one piece of a complex puzzle involving metabolism, activity levels, and gut health.

In 2022, 1 in 8 people worldwide were living with obesity, a prevalence that has more than doubled since 1990. This startling rise begs the question: what factor contributes to the increasing prevalence of obesity, and why is the issue becoming more pronounced globally?

According to the Centers for Disease Control and Prevention (CDC), the average American male and female consume hundreds of calories more per day than they did in the 1970s, making a consistent calorie surplus one of the primary drivers of excess body fat. Understanding this fundamental energy balance is crucial for identifying what truly contributes the most to body fat.

Studies show that many people who believe they eat very little may actually consume more calories than they realize. If you've asked yourself, 'Why do I have a big belly even though I don't eat much?', the answer might involve more than just your food intake and could be related to factors like stress, poor sleep, or hormonal changes.

According to the World Health Organization, worldwide adult obesity has more than doubled since 1990, highlighting a complex issue with no single culprit. While many factors contribute to weight gain, pinpointing what is the biggest cause of body fat requires understanding the interplay between diet, exercise, genetics, and environment.
