Researchers at Purdue University found that when obese people have negative interactions socially or feel discriminated against, it contributes to their declining physical health.

He explained that being overweight is a significant risk factor for being obese, which then puts people at risk of serious health conditions such as cancers, heart disease and diabetes.
