Sure. Can't give you an exact list, but start with https://www.reddit.com/r/keto/wiki/faq https://www.reddit.com/r/keto/wiki/faq and then take a look at dietdoctor.com who have a 2 week (I think) intro to keto which gives you some decent variation with keto food (and worked really well for a friend of mine). I use MyFitnessPal to track what I eat and keep below 20g of net carbs every day (usually coming in around 10-15). Good luck with it - IBS is absolutely miserable.
