Why Some Populations Develop Diabetes at Lower Body Weight

Not every population develops metabolic disease in the same way.

Some groups may develop:

• insulin resistance
• fatty liver
• Type 2 diabetes

at lower BMI than others.

Why this happens

Body weight alone does not tell the full story.

Important factors include:

• visceral adiposity
• liver fat
• insulin sensitivity
• beta-cell reserve
• genetic background
• ancestral diet history

This is why two people with the same body weight may have very different metabolic risk.

The role of food mismatch

Modern industrial foods can overwhelm populations whose ancestral diets were very different from the modern sugar-heavy, ultra-processed food environment.

This is especially important in:

• South Asia
• East Asia
• Pacific populations
• Indigenous communities

Bottom line

Low or moderate body weight does not guarantee metabolic safety.

In many populations, diabetes risk depends more on visceral fat, liver fat, insulin resistance, and food mismatch than on weight alone.
