Don't be stressed when you eat
The blood supply to your gut (and reproductive organs) literally shuts down when you're stressed. So when you're eating whilst thinking / feeling stressful things at the same time, an awful lot of damage can be done to the gut. Even reading emails, looking at bank statements (if they're not the way you want them to be!), being on social media, seeing images on Instagram that make you feel bad, ALL impact that blood supply to your gut. Get yourself to a calm place, breathe before you start eating and don't multitask or get involved with anything that can make you feel bad.
