That body, in the state it’s in right now as you faithfully spend time with God and seek him, seek balance and health. Your worldview may implode here for a min, let me help you. If you say that Jesus is Lord, but we treat our bodies poorly, or even just shove them aside with disregard, we are living in conflicting belief systems.
In this age, with no temple or tabernacle, the spirit of God resides in us, WE are the temple, the holy of holies being within this very body, tired or hungry as it may be.
This is profound, because we do not have to travel to the place where Yahweh resides, he resides INSIDE. So when I say, “Your body is the Temple of the Holy Spirit” it’s not a metaphor to clean up your eating. Its literal.
Look in the old testament how detailed the temple is described…
Do you think God cares about the detail and beauty of where he resides? Yes. His description of the wood doors, the carvings, the gold overlay, we know he loves beauty, loves detail and that these things matter. He cares if we treat our bodies poorly, if we over eat and become couch potatoes. He cares if we push our bodies aside day in and day out, putting responsibilities and people before our own self care: not making time to get that zumba class in, not sleeping, eating on the run etc. .
He cares if the pendulum swings the other way as well: if we become obsessed with our bodies. If, in vain we become addicted to exercise or restrictive with food to the point of disordered eating, or focus on our physical appearance over our relationship with him.
We either neglect the gift he’s given us or we glorify it above God him self and the balance hes looking for is worship. Your body matters to God, because it’s his temple, where his spirit and glory reside and where others see his reflection and when we take care of it, it’s an act of worship.
There is never any distinction in the bible between “spiritual life” and other area’s of life—it is all spiritual. What we eat, drink, say, watch and do are spiritual and can be worship in the highest form when they fall into line with how God designed us to be.
