the diet you're trying now is overall a good diet fermented foods are a good source of Vitamin K and fiber is helpful with weight loss furthermore Koreans love Kimchi and meat and they are some of the longest lived people however if your IBS doesn't get resolved you can't say carnivore failed because unless you eliminate plants it's not carnivore also i don't know what Kimchi tastes like but sour and spicy foods stimulate appetite and are counter productive to weight loss efforts. yes i know Vitamin C is sour and most natural sources of it are also sour but it's something i have to mention. the solution is if you must eat something sour like strawberries as a source of Vitamin C then eat it before your scheduled meat meal - this way you will boost appetite only for a very short time and will extinguish it with the meat - and actually the acidity will help with digestion do NOT eat anything sour or spicy at the end of meals or in between meals or you will become unnecessarily hungry
