According to a 2019 study published in *PLOS Genetics*, thin individuals tend to possess fewer genetic variants associated with obesity. If you often wonder, "Why am I thin even if I eat a lot?" the answer can be complex, involving a mix of genetics, lifestyle, and potential health factors.

According to a 2024 study, the most common causes of unexplained weight loss include digestive disorders, psychiatric conditions, or cancer. While genetics and a high metabolism can play a role, significant, unintentional weight loss is often a sign that an underlying issue, whether physical or psychological, needs addressing.

According to a study published in *Science* in 2021, metabolic rate generally remains steady between ages 20 and 60, challenging the common assumption that metabolism significantly slows down in midlife. Despite this, many women struggle to gain weight, leading to concern and confusion.

Did you know that your basal metabolic rate (BMR), the energy your body uses at rest, can account for up to 80% of your daily energy expenditure? For some, a naturally high BMR is a key reason why they are skinny even if they eat a lot, but other factors like genetics and nutrient absorption also play a critical role.

Approximately 1-2% of adults are clinically underweight, often wondering: 'Why am I skinny but eat so much?' The answer involves biology, genetics, and habits, not just diet.

According to the World Health Organization, 390 million adults were underweight in 2022. This highlights that being unable to gain weight is a significant global health issue, often linked to various medical, psychological, and lifestyle factors.

According to research published in the journal *Nature*, one in 2000 people has a specific genetic duplication that makes them much more likely to be extremely skinny. This highlights that for some individuals, the answer to **what is the cause of getting skinny?** is deeply rooted in their DNA, rather than being a simple matter of diet or lifestyle. However, many other factors, ranging from diet and metabolism to emotional and medical conditions, can also play a significant role.
