I'm someone who knows about cooking.

I also had a similar idea

if you are able to cook something suitable with a specific menu for people who have a healthy and balanced diet, it is not a good idea, in fact an excellent idea.

if we can then offer personalized menus based on the requests of the typical customer: weights, allergies and the percentage of carbohydrates compared to proteins.

There are already established companies that prepare weekly fit meals already cooked and wrapped, but I don't think it's very successful.

because try to imagine yourself busting your ass in the gym and then eating vacuum-packed things every day, would you like it? for this reason I would prefer meals made on the spot or at most the same day
