These changes took off in the second half of the 20th Century, giving rise to what scientists call the “obesogenic environment” - that is, one that encourages people to eat unhealthily and not do enough exercise.

But Dr Margaret McCartney, a GP in Glasgow, cautions: “If we keep putting people into an obesogenic environment, we’re just going to increase need for these drugs forever.”

We know the obesogenic environment starts early.

Do you think we should also tackle the obesogenic environment or just treat people when it’s starting to damage their health?

The researchers tested three obesogenic scores, two of which were developmentally sensitive scores that excluded milk, yogurt, and cheese.
