Need Smart People to answer this XD

Why would you want to eat those same foods over and over.

Metabolism is affected by muscle mass not by foods you eat.

You could survive on nearly anything if the calories are adequate. The thing is that it's typically much healthier to eat a variety of foods so that you get the vitamins and micronutrients your body needs, and a mix of macros to be more pleasant.

If you just want a simple menu plan to repeat, that's easy enough, but you won't stick to it if you don't like it.

Calories are what is important for weight management so that is what you should look at.
Eat whatever foods add up to meet your calorie goal not "eat this many pounds of food a day". You might eat a lot of very low calorie foods or a smaller amount of very calorie dense foods.
The concern would probably be getting all the nutrients you need in a very limited menu and how sustainable and satisfying it is for you.
Protein, fats and fiber help people feel satisfied.

Log some of the foods you like in your food diary and see how they help you meet your goals.

It sounds like you want to simplify so you are not faced with choices so frequently. One way to do this and still eat healthfully would be to eat only meat (beef, pork, chicken, fish) and non-starchy veggies. Most people will lose weight eating these foods only, unless you have an insatiable appetite for meat.

So what are the minimal amounts of foods you could live on. And what are they. "Example you could live on potatoes rice and pizza eating 1 pound of each each day"
Also does eating the same food affect your metabolism?

You chose potatoes, rice, and pizza for a reason. Is that what you intend to eat every day? A pound of each?

I'd probably go with a high quality beef. Everything is there. It shouldn't affect metabolism unless you just eat lean meat with high protein.

I wouldn't want to do it though. Id' crave variety.

No, not everything, no vitamin C or D, no fiber, low in Omega 3 and so on.

Not if you get beriberi or scurvy.

If you really want the minimum, that Soylent (real, not a joke) meal replacement supposedly has all the necessary nutrition. I can't imagine it tastes like anything I'd want to drink once let alone for every meal.

I rotate each week between different veggies, fruits and grains but my go to meats from week to week are mainly -ground turkey and chicken. This weekend I might throw in a Margarita for good balance lol

This is a good point. At the extreme, people can't survive on a diet that's nutritionally inadequate, no matter how many calories they're eating. Sailors on ships used to die of scurvy even though they were eating enough calories. And even if someone doesn't die, nutritional deficiencies can have all kinds of bad effects. Eating the same food or only a very limited range of foods is nutritionally a bad idea.
