The main reasons I've seen from vegans for not eating meat seem to be all about the morality of eating a sentient animal, the practices of the modern meat industry, and the environmental impact of it. And don't have anything to do with the taste of meat.
Since lab-grown meat doesn't cause animal suffering, and assuming mass production is environmentally friendly, would you consider going back to eating meat if it were the lab-grown kind?
I would not trust anyone who tells me it's lab grown. I've had so many restaurants and people lie to me that someone ws vegan, out of malice and out of incompetence, that I just would not believe that a burger was "lab grown" instead of made with cheap meat leftovers.
If somehow I I could assure that it was made without animals being hurt, maybe. Meat is unhealthy so I would still mostly avoid it.
The human body is an amagin versatile machine. But the best diet for health seems to be plant based whole foods. Meat should be a very small part of your diet. It has been linked to all main causes of death like heart disease, diabetes, Alzheimers...
