Thanks! The only problem is that i don't know how to get the "calories you need to eat" variable, because if the bot ask the user during the talk, the user would have to type a lot of things. I thought on creating a kb whith all the nutritionist diets to, but it's not going to be that precise, and the nutritionist is going to update that kb a LOT. So, now I'm thinking in create one login sistem, i guess it woul work better, but also don't know how to do that lol
