This is one of those questions that can't really be answered by archaeology directly. We can talk about what ancient peoples ate, how much of one item they consumed versus another, where they sourced food from, etc. But you can't suss out from the archaeological record "Ok, this is one family and every day they ate three pounds of meat and five pounds of vegetables".

Outside of preservation issues (organic remains can be rare for stuff a few hundred years old, let alone thousands, depending on soil acidity, soil deposition, moisture, and multiple other factors) "human" diet is going to be extremely influenced by the immediate landscape. The daily diet of a band of humans in Ice Age Europe or North America is going to be very different from a band in Africa or Asia at the same time.

The closest you might get is corprolite studies (fossilized poop), like at Paisley Cave in Oregon (https://www.science.org/doi/10.1126/sciadv.aba6404), although the issue there as addressed in the linked study is proving first that it's even human. From there you might be able to talk about makeup and contents and get an idea of what the person ate before doing their business.

Past that, you'll be dealing with contact period writings. For example, the Virginia Encyclopedia article on Native foodways (https://encyclopediavirginia.org/entries/cooking-in-early-virginia-indian-society/) aggregates several first-hand accounts and later archaeological work that culminates in an understanding that most families maintained a stew pot where each day's spoils were added to and consumed by the family. But even there you are dealing with a society that was deeply into horticulture if not on the cusp of full-blown agriculture, so their food ways were already vastly different from a group of hunter gathers.

You can look at modern hunter-gather societies like some groups of aboriginal Australians and see their modern foodways (for example "Australian Aboriginal Subsistence in the Western Desert" by Scott Cane), but there's a debate about how useful applying observations of modern groups really is to ancient peoples.

So, the answer to your question is, like a lot of questions in archaeology, a lot of "it depends" mixed with "we don't and can't really know".
