Entirely anecdotal, perhaps useless information (and off-topic for anyone who doesn't current consume caffeine) but I've never had an easier time losing weight than I have since I entirely quit using caffeine after decades of normal usage.

After eliminating caffeine its like a switch entirely flipped in my brain turning off all the usual cravings I'd have for carbs/sugars/etc.

The quitting caffeine part was pretty horrible though. Not just because of the headaches (which weren't actually super bad for me) but I went through a couple of weeks of what I assume was for-reals depression/anhedonia as my brain figured out how to operate with non-blocked adenosine suddenly suppressing my dopamine levels.
