Body stewardship — what Christians owe their metabolism.

April 14, 20268 min read

“Your body is a temple.” Most Christian wellness content treats this as a slogan — an inspirational phrase to hang under a photo of a sunset. Scripture is more specific, and more demanding, than that.

Here is what body stewardship actually means in a 2026 food environment — and what the metabolic research has to say about it.

For the broader pillar — the six disciplines, the failure modes, the science of each — read the full body stewardship guide. This essay goes deeper on the metabolic specifics.

What the scripture actually says about the body

Three passages carry most of the weight:

“Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore glorify God with your body.” — 1 Corinthians 6:19–20
“Therefore I urge you, brothers, on account of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God, which is your spiritual service of worship.” — Romans 12:1
“And whatever you eat or drink or whatever you do, do it all to the glory of God.” — 1 Corinthians 10:31

Three verses, three claims: your body is not yours, your body is worship, and eating is theological. There is no way to read these passages as decorative. They are operational.

What “stewardship” actually means

Stewardship is a specific word. A steward does not own — a steward is responsible. Faithful stewards are accountable for what the owner entrusted to them. Unfaithful stewards let the estate deteriorate, rationalize the deterioration, and eventually answer for it.

Applied to the body, this means: the body that God gave you is his. You are responsible for it. Deterioration that is avoidable is not neutral. It is a stewardship problem.

What the research says about the cost of not doing this

The metabolic landscape in 2026 is unprecedented:

  • Type 2 diabetes has tripled since 1980 (CDC National Diabetes Statistics, 2024).
  • Roughly 30% of adults globally have non-alcoholic fatty liver disease (NAFLD) — US prevalence is comparable (Younossi et al., 2023, Hepatology).
  • Only ~12% of adults meet criteria for metabolic health — optimal blood pressure, blood sugar, waist circumference, lipids, and no medication (Araújo et al., 2019, Metabolic Syndrome and Related Disorders).

In a food environment this hostile, doing nothing is not neutrality. It is neglect of a stewardship. Scripture is not asking Christians to be health-obsessed — it is asking them not to be asleep at the wheel.

What stewardship looks like in practice

Not perfectionism. Not orthorexia. Not vanity. Stewardship looks like:

  • Knowing your basic metabolic numbers — fasting glucose, A1C, blood pressure, lipids.
  • Eating in alignment with how your body actually works — protein first, meals earlier, eating windows.
  • Moving daily — not gym-obsessed, but not sedentary.
  • Sleeping enough that your hormones can regulate.
  • Fasting occasionally — as scripture assumes.
  • Being honest about drift before it becomes disease.

None of this is extreme. It is ordinary faithfulness with a body. And in 2026, ordinary faithfulness is increasingly countercultural.

The honest caveats

Stewardship is not weight. Weight is one signal among many, and not the most important one. The stewardship question is metabolic health, not body composition.

Stewardship is not legalism. You can eat a slice of cake without sinning. You can miss a workout without sinning. Stewardship is about pattern over years, not purity at every meal.

And — critically — Isaiah 58 still applies. If stewardship is making you more irritable, more judgmental, or more preoccupied with yourself, the fruit is wrong and the practice is off.

The honest bottom line

1 Corinthians 6:19 is not a slogan. It is an assignment. In a 2026 food environment, the assignment asks more of Christians than it did two generations ago — because the environment is more hostile. Stewardship, in practice, is showing up for your own metabolism with enough attention that your body can still do the work God gave it.
