What does it mean to not to turn away from your own flesh and blood? Is it not to share your food with the hungry and to provide the poor wanderer with shelter— when you see the naked, to clothe them, and not to turn away from your own flesh and blood? (Isa 58:7 NIV).


Does this mean more like members of the family, or my own physical body? Thanks.
A number of translators interpret "your own flesh" as your family/relatives. Comparison

This passage is a(nother) condemnation of Israel for being phony in their religious observances. God asks them what they think he really wants, then lists things that are actually what he wants. A person always has a higher obligation to his family than to others, and so in this context, I think it makes the most sense to understand it as talking about helping your relatives (esp. your parents).
