They should invent a machine that scans my body and then a little hatch opens and inside is the exact right food with all my needed nutrients and calories for the day.
You work extra hard that day and burn too many calories? No problem. The Machine gives you more when it scans you tomorrow.
The Machine gives you food in bricks, like high fibre protein bars, and you can tell it your favoured flavour profiles, temperatures and textures for your bricks. If you ask it to do something that it can't do inside your nutrient requirement parameters (like ask it to make your food really salty when you don't need that much salt), it beeps a warning at you and tells you what parameter you're exceeding, but if you confirm that that's what you want then it will still make it for you. It also has drink options (but will warn you that a healthy diet contains a plenty of solid food). The Machine will also dispense your daily medications so that you remember to take them.
