Tell fatties to eat healthy and exercise and they will still eat TONS of food. Just different food. They will eat shit that they perceive as healthy, such as gluten-free muffins and fruit juice. Even if they did eat actual healthy food, they would still eat way too much. So OP is spot on.   THISTHISTHISTHISTHISTHISTHISTHIS Remember how 300and30 bragged about "weight loss" when she went to the gym, and found out she wasn't losing weight because she was eating 5,000-6,000 calories a day?  Years after "starting her weight-loss journey," she's currently several stones above her starting weight.  Muh Fierce Womyn Deadlifts indeed (PS: this is what a real athlete looks like).  And FatPeopleStories upvoted her for "not being full of fatlogic"--more upvotes than they gave for posts by nurses and EMTs who have to risk their vertebrae to lift fat people.  They will eat shit that they perceive as healthy, such as gluten-free muffins and fruit juice.   See also: Amberlynn Reid's list of "healthy snack ideas."  Hams don't go for CICO, keto or fullness-to-calories ratio (if they did, it would make their lives a lot easier in terms of losing weight).  They go for stuff with a halo effect of being "healthy."  My thin coworkers would eat stuff like Bird's Eye frozen vegetables for lunch, and add MSG to make it more savory.  I never, ever saw a fat person do that my entire time working there. You don't need to exercise to lose weight!  Walking a mile is only about 100 calories.  If you get the munchies from exercising, you're better off not doing it.  On a related note, stimulants are good for reducing the aforementioned munchies.  Even a low dose of Adderrall like 5 mg.  CICO should be priority number 1. If they can follow CICO, THEN worry about eating healthy and exercise...  I can verify this from personal experience.  Learning about food pyramids and "don't eat X, don't eat Y" and all that other stuff was too damn complicated and made me not want to do it.  I planned on giving up, on hoping height keeps me from getting too fat.  Discovering /r/fatlogic, CICO, and being motivated by contempt of fat people changed my mentality completely.
