No, all the problems wouldn't go away. But a healthy-weight population would cost roughly 64% less to treat, which implies a 64% reduced hospital congestion and workload. This could get offset somewhat as people die later in life of "old age" rather than chronic conditions or CVD events, but those costs would be much lower. So let's say a 50% reduction over the long run.
