People in the 70s didn't all have bariatric surgery, or access to miracle drugs to control hunger hormones. Nor did we all develop some mutation that caused the current obesity epidemic. Clearly something in our environment has changed. Seems to me that it would be simpler to figure out what's changed between now and then, rather than try and invent new drugs. I.e. we need to do root cause analysis rather than flounder for workarounds. Some have suggested that the carb-heavy government food guide pyramids are to blame. That seems to be a good place to start.
