How many hamburgers would it take to clog an artery?

I ate 2 double cheeseburgers, a small order of fries, and a large sweet tea everyday for about 3-4 months and gained 50 pounds. I didn't feel like I had any energy ever. It is extremely unhealthy to eat at a fast food restaurant more than I'd say, once every two weeks. Another key is exercise. I don't think it would have taken more than a few more months, and I would have had serious health issues. I absolutely think that the living people would be healthier, but some would die of starvation because there are some people out there who simply refuse to cook for themselves.
