Now that I think about it, I haven’t been sick since I started getting the weight off. I usually catch two or three bugs a year, but so far so good. That could change though.
I’ve read a little about this and apparently one of the reasons that obesity affects immunity is that it’s easier for wounds to remain open and for pathogens to enter that site in obese people. There’s generally more surface area that’s affected due to having larger bodies. Plus, the layers of fat impede the body’s ability to heal itself as it’s harder to keep the wound clean and dry due to the skin folds.
