Thinner people are healthier in that they won’t suffer from the same medical issues that plague the obese. A thin person might have high cholesterol, but they’re not going to also have the same increase chance of heart disease an obese person will see. No individual who’s 300lbs is healthy, obesity in and of itself is the disease. The fact thin people suffer from other, non-weight related diseases doesn’t mean there is not point in not maintaining a healthy weight.

Food insecurity is not a solution to the obesity epidemic, but eating a couple hundred calories per day less than maintenance is also not starvation. And ensuring healthy foods and produce are more affordable than unhealthy and high-processed alternatives is a great way to kill two birds with one stone.
