<s>[INST] My father is recovering from a severe gallbladder attack resulting in sepsis , etc. Pending his next evaluation, while on antibiotics , he was instructed to be on a NO FAT diet. He has eliminated all meats, oils , & dairy (except non-fat milk). What about plant-based fats such as lentils, rice, beans, etc.? His doctor is on holiday & unavailable for advising. [/INST] Hi and welcome to Healthcare magic.Thank you for the query.You can have such fats,but try to have more frequent but smaller meals.Also,avoid alcohol and smoking completely. animal fats,especailly pork, will trigger gallbladder attack so you should avoid fried food,spicy food and food that cause bloating. And drink plenty of fluids with meal.Wish you good health. Regards </s>
