Obesity increases the risk of dozens of other diseases. Which ones? And by how much? In 2020, Dr Greger published a video series called 'The ABCs of Obesity' in which he covered these diseases in alphabetic order: Arthritis, Back Pain & Blood Pressure, Cancer, Diabetes & Dementia, Encephalopathy (brain disease), Fertility, Gallstones & Acid Reflux, Heart Disease, Immune System, Jaundice (NAFLD — Non-Alcoholic Fatty Liver Disease), Kidney Disease, Lung Function, Metabolic Syndrome, … Basically, obesity increases the risk for all of these diseases.

Watching this video series may help us remind ourselves why we should avoid obesity.

What if we are simply Overweight, not Obese?

In the 'ABCs of Obesity' video series, Dr Greger doesn't talk about the Overweight category. Remember that CDC (USA) has defined four BMI categories: Underweight, Normal, Overweight and Obese. Made me wonder: Does the risk of all these diseases go up if we are merely Overweight and not Obese? If so, by how much?

Also, if we are of Indian sub-continent origin, it would help to look at India-specific BMI cut-offs. Indian scientists have proposed that BMI > 25 should be the cut-off for Obesity instead of BMI > 30. Using the new threshold, many Indians who are classified as Overweight today would be classified as Obese!
