Have you ever noticed that some people stay skinny no matter what they eat ? From a fast metabolism to hormonal balance, there are numerous reasons behind it. Tap to know why it happens!

Fast Metabolism

Some people have a fast metabolism and some may have a naturally high BMR (Basal Metabolic Rate), i.e., they burn more calories at rest, which keeps them skinny.

Healthy Gut Microbiome

Many people stay skinny despite eating anything because they have a healthy gut microbiome, which helps prevent inflammation and absorb nutrients properly.

Insulin Sensitivity

Individuals with better insulin sensitivity are more likely to stay skinny even after eating anything, as their bodies are able to process glucose more effectively.

Physical Activity

Even if skinny people don't hit the gym, their active lifestyle like going for a walk, doing household chores, and more, makes them stay skinny.

Hormonal Balance

When hunger, satiety, and thyroid hormones are balanced in an individual, they are least likely to gain weight or overeat, helping them maintain a healthy weight.
