If you don't feel you can tolerate more carbs, don't do it. I decided at the start to go as low in carbs as I could because I knew that I was seriously metabolically compromised. I wasn't obese but I was capable of gaining weight even when exercising 14 hours a day on a calorie deficit. Every now and then I will eat some sweet potato (like once a week) but other than that, I do not eat any fruit and only eat leafy greens and mushrooms if I ever eat vegetables at all. I feel this is better for me. I think sometimes suggestions like eating 50+ grams of carbs a day or the 80/20 rule and things like that are to make the diet more inviting to newcomers. It'll work for a lot of people just fine, but I truly believe that the diet has to be way more stringent for it to be effective (i.e. weight loss, metabolic healing, end of carb cravings, loss of ravenous hunger) for some people.
