Old weight gain stories can teach us about the social and environmental factors related to weight gain. In the past, there might have been less emphasis on body image, and weight gain could be more related to things like family traditions of big meals or living in areas with limited recreational facilities. Understanding this can help us see that weight gain is not just an individual problem but can be influenced by our surroundings. We can then work on changing our environment or family habits if needed to promote a healthier weight.
