I turned that Stylish style setup I rigged up for the Ad Lib April challenge into a Greasemonkey/Tampermonkey script, since most of the people here already use it for the net carb and/or the macro settings scripts. Now, you can remove the calorie column from your dairy, and it won't interfere with your view of your friends' diaries!

(Disclaimer - no, this doesn't change the display on the mobile app, and you need to install it on any computer you use to get the effect. Sorry, that's just how these things work.)
