Elite body builders in the 1970's world would eat 5,000 a day. These guys trained nearly daily. The output of their 'work' to me would equal or way exceed what Bigfoot would put out in a given day in Bigfoots world. That's just my guess as a max for reasonable estimate. Yes, these guys weighed under 250lbs back in the 1970's Gold's Gym era of weightlifting. I would think Bigfoot would only be as active as Bigfoot needs to be. Bigfoot would rest often and essentially be a couch potato until food, reproductive needs, or whatever motivated Bigfoot.
Skeptics are skeptics because these reasonable points about Life Support make them skeptics. We should expect if bigfoot is as common as some say, we should have more of these sightings in trash cans, and so on. Trash cans tend to exist in towns and cities vs out in the middle of nowhere. Many have security cameras and Ring doorbells. The most likely reason to explain this must be Bigfoot are few in number, live in massively remote areas, and are shy to human activity.
I don't know how credible Bigfoot sightings are when all over the country. Many are just in unlikely places and unlikely regions. I am sure they see something just not bigfoot.
If Bigfoot was in all these areas the trash cans would be raided, the farms would be raided, and so on.
Bigfoot being near extinct is a better explanation vs attributing ninja skills to bigfoot to explain it.
If you bet on finding Bigfoot, you would bet on the PNW more so than downtown NY City.
