Misinformation

Okay so I know that influencers are just full of it but the amount of his information out there really confuses me, because there are some amazing nutritionists on tiktok and Instagram who are talking about how good pre-fueling is and refined carbs before working out. But then there's other influencers who say that you need to do fasted cardio for 30 minutes on an incline walk and then have 30 g of protein afterwards and avoid refined carbs - and that the Stairmaster makes them inflamed but the treadmill doesn't??? what

It's no wonder people get so confused so quickly because it's even making me question my workout and eating routine. Anyone else feel this way?
