McScience is the fat logic equivalent to Bro Science. Jesus fucking christ, its like everyone who has anything to do with the human body comes up with their own stupid fucking rules of how the body works and none of it is true. The wannabe barn houses have their bro science and supplements trying to build muscle as if its any different than eating and working out and the lardholes have their freaking fat theories as to why their body puts on fat as if its any different than eating and working out.  Next time someone tells you a nice story about why they're fat tell them "Thats some nice McScience but can you back that up with some studies?" Lets start to discredit any "Thyroid" or PCOS or Hormonal bullshit the fatties tell us.  I'll start: PCOS accounts for a BMR reduction of about 400 calories according to these guys . So if you're a fat butter huffer with PCOS, you do have to work harder to keep the weight off but that doesn't mean you can't you just need to burn about 400 more calories through activity, which just so happens to be about an hour of biking. There, you're single best excuse for being a fat piece of shit is gone. PCOS as an excuse for weight gain is McScience.
