I have created a python program for exactly that purpose. Its nothing fancy. A yaml file of ingredients, another yamk fole of recipes and a yaml file for nutrient target and then some optimizers and some constaimt enforcers. I can now decide what I want to eat that day and the program tells me what quantity I should eat, what ingredients I need, what ingredient I need to buy, how much time it will take for cooking and how much meal prep boxes etc Extremely helpful for weight loss
