• possible food intolerance - have you any knowledge of potential food intolerances/do you have any other symptoms?
• poor food combining - look it up on google and see if you can incorporate some of this into your diet! I personally don’t bother with food combining, but it’s possible that you’re more sensitive to bad food combinations than others.
• are you overeating? I know lots of raw food/801010/hclf people encourage eating lots at meal times, but if you’re not used to eating large volumes of food it would make you feel unwell! Perhaps build up to eating larger amounts by slowly increasing your portion sizes. Or eat more frequent, but smaller meals throughout the day!
Remember to listen to YOUR body, do what’s right for you! Experiment, find out what makes you feel good. Everyone’s bodies are different and require different intakes etc.
I hope this has helped a little!
