Detox
If you’re over 50, love Jesus, and feel like your body just isn’t cooperating anymore, you are not alone. So many Christian women and men tell me the same things:
“I look at food and gain weight.”
“I’m more tired and achy than I used to be.”
“My doctor says it’s just age, but something feels off.”
In a world of quick fixes and fear-based health messaging, it’s easy to forget that as Christians, our health is not just a physical issue. It’s also spiritual, emotional, and relational. True Christian health care is about caring for the whole person—body, soul, and spirit—in a way that honours God and works with the season of life you’re in.
In this podcast episode and blog post, we’re going to unpack a simple, Christ-centred approach to health after 50.
Let’s talk about:
• A biblical mindset for health and aging
• How to support your metabolism naturally after 50
• Gentle, realistic detox and lifestyle rhythms
• Plus, a unique tool you won’t find in the podcast: a “Rule of Life for Christian Health After 50” you can start using today.
Throughout, I’ll also share how we walk this out more deeply inside my 6-month Christian group coaching programme, Health for Life, where we put all of this into practice with teaching, coaching, and supportive community.
Before we get practical, let’s start where we always should: with God’s Word.
“Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God…? Therefore glorify God in your body and in your spirit, which are God’s.” (1 Corinthians 6:19–20, NKJV)
That verse isn’t about perfection. It’s about stewardship. Christian health care is not about chasing somebody else’s body or youth; it’s about stewarding the body you have now, in the season you’re in, for the glory of God.
A lot of the battle after 50 isn’t just in your body. It’s in your mind. Many of us have absorbed two unhelpful extremes:
• “It’s all downhill from here; there’s nothing I can do.”
• Or, “If I just try harder, restrict more, and hustle, I can look and feel 30 again.”
Neither of those is biblical, and neither leads to peace.
Scripture gives us a different picture of aging:
“Even to your old age, I am He, and even to grey hairs I will carry you!” (Isaiah 46:4, NKJV)
“The righteous shall flourish like a palm tree… They shall still bear fruit in old age.” (Psalm 92:12–14, NKJV)
So, what does a renewed, Christ-centred mindset look like in practice?
First, you acknowledge that your body does change with age—and that’s not a moral failure. Research shows that resting metabolic rate declines gradually with age, largely due to muscle loss and hormonal shifts, not because your body is “broken” or you’ve “failed” [1]. When we frame every change as failure, we slip into shame and passivity. When we frame it as a stewardship opportunity—“Okay, my body needs different things now”—we move into wisdom and partnership with God.
Second, you shift your goal from “skinny and young” to “strong, clear, and faithful.” Our culture worships youth and thinness; the kingdom prioritizes fruitfulness, longevity for service, and being available to God’s call. That might mean saying no to extreme diets that damage your metabolism or overly punishing workout plans that spike cortisol and leave you exhausted. Studies confirm that chronic crash dieting and severe caloric restriction can reduce metabolic rate and increase the likelihood of weight regain [2]. That isn’t good stewardship.
Third, you begin to see health as a form of discipleship, not just self-improvement. When you eat real, nourishing food, move your body, and prioritize sleep, you’re not just “being healthy”—you are honoring the God who created you and equipping yourself to love others better. Romans 12:1 calls us to present our bodies as a “living sacrifice, holy, acceptable to God, which is your reasonable service.” Your body is part of your worship.
In Health for Life, this mindset piece is one of the first things we work on, because until the mind is renewed, every new “plan” just becomes another diet you start and stop. Once you see your body and your health as God sees them, you’re far more likely to follow through with compassion, consistency, and hope.
Let’s talk metabolism, because this is where a lot of frustration lives. Yes, metabolism tends to slow with age—but that does not mean you’re doomed. It just means your strategy needs to shift. Think of it less like a “fast or slow” switch and more like a complex orchestra you can still conduct wisely.
One of the biggest levers you can pull after 50 is muscle. Muscle is metabolically active tissue—meaning it burns more calories at rest than fat mass. Research consistently shows that resistance training in older adults improves muscle mass, strength, and metabolic health, and can even reduce risk for type 2 diabetes and cardiovascular disease [3]. You don’t need to become a bodybuilder. Two to three days per week of simple, progressive strength training—using bodyweight, bands, or light weights—can make a huge difference.
Protein is another key. Many people in midlife and beyond are unknowingly under-eating protein. Studies suggest that older adults may need a higher protein intake (around 1.0–1.2 g/kg body weight per day) to maintain muscle and support metabolic health [4]. That might look like:
• A palm-sized portion of protein at each meal (eggs, fish, chicken, Greek yogurt, legumes)
• A focus on protein especially at breakfast, to stabilise blood sugar early in the day
Speaking of blood sugar, stabilising it is one of the most loving things you can do for your energy, mood, and weight after 50. When we live on refined carbohydrates, sugary snacks, and constant grazing, we create repeated blood sugar spikes and crashes, which can contribute to increased hunger, fat storage, and higher risk of insulin resistance [5]. A “Christian health care” plate might look like:
• Half your plate non-starchy vegetables (broccoli, greens, peppers)
• A quarter of your plate protein
• A quarter of your plate healthy carbs (sweet potato, quinoa, fruit)
• A thumb-size of healthy fat (olive oil, avocado, nuts)
Add to that well-hydrated cells—most older adults simply don’t drink enough water. Mild dehydration alone can affect energy, cognition, and even appetite regulation [6]. Aim for sipping water throughout the day, not chugging at night.
In Health for Life, I help you customise these principles to your body, your life, and your preferences—no rigid meal plans, but clear, simple structures that support your metabolism in this season.
When we hear “detox,” many of us think of extreme juice cleanses or expensive powders. But from a biblical and physiological perspective, detox is something God built into your body. Your liver, kidneys, lungs, skin, lymphatic system, and gut are detox systems that run 24/7. The question is not, “Can I force my body to detox?” but, “How can I support the organs God already gave me?”
First, focus on what you can remove, not just what you can add. Reducing ultra-processed foods, added sugars, and alcohol can significantly lighten your liver’s load. Research links high consumption of ultra-processed foods with higher risks of obesity, cardiovascular disease, and overall mortality [7]. Swapping packaged, chemically-laden foods for whole, minimally processed foods is one of the most powerful daily detox strategies you can use.
Second, support elimination. Your body needs to move waste out efficiently—through your bowels, urine, sweat, and breath. Constipation, for example, can increase the time that potential toxins and waste products sit in the colon. Adequate fiber (from vegetables, fruits, legumes, seeds), hydration, and regular movement all support healthy elimination. Studies show that dietary fiber intake is associated with reduced risks of cardiovascular disease, type 2 diabetes, and certain cancers [8], in part because of its role in gut and metabolic health.
Third, prioritize restorative rhythms that calm your nervous system. This might not sound like “detox,” but chronic stress actually alters your physiology, hormones, and even gut health. Elevated cortisol over time can contribute to abdominal weight gain, poor sleep, and inflammation [9]. Christian health care must include what I call “holy rest”:
• A real, protected sleep window (aiming for 7–9 hours when possible)
• A simple evening unwind routine (dim lights, no heavy news, gentle stretching, prayer)
• Rhythms of Sabbath and quiet with God
Jesus Himself modeled rhythms of withdrawal and rest: “So He Himself often withdrew into the wilderness and prayed.” (Luke 5:16, NKJV) Your body’s detox and repair processes are most active when you’re resting and sleeping. You are not being lazy by resting; you’re participating in God’s design.
In Health for Life, we turn these concepts into simple weekly actions—one or two changes at a time—so you’re not overwhelmed, but steadily giving your body what it needs to detox and heal.
Here’s something I didn’t share in the podcast, but I want you as a reader to have: a simple “Rule of Life for Health After 50.”
In church history, a “rule of life” is a set of intentional rhythms that help believers live in alignment with their values and with God. You can create a gentle, health-focused rule of life that reflects Christian health care in this season. Here’s a template you can personalise:
Daily Body Care:
I will move my body for at least 20–30 minutes most days (walking, stretching, or strength).
I will include a source of protein at every meal.
I will drink water regularly throughout the day.
Daily Soul and Spirit Care
I will begin or end my day with 10–15 minutes of unhurried time with God (Scripture, prayer, journaling).
When I feel tempted to shame my body, I will pause and speak truth over it: “I am fearfully and wonderfully made” (Psalm 139:14).
Weekly Rest and Reflection
I will honour a weekly Sabbath rhythm—a window of time where I cease striving and allow God to restore me.
Once a week, I will reflect: “What helped my body feel supported this week? What drained me?” and adjust one small thing.
Relational Support
I will not walk this health journey alone. I will intentionally seek community—whether that’s a church group, a walking friend, or a Christ-centred coaching space.
Write this down, personalise it, and post it somewhere visible. This isn’t about legalism; it’s about creating a simple structure that makes it easier to live out what you say you value.
If you want help actually living your rule of life—with accountability, coaching, and Christ-centered community—this is exactly what we do inside Health for Life, my 6‑month group coaching program for Christians. We combine biblical truth, evidence-based nutrition and lifestyle strategies, and practical weekly action so you don’t just “know” what to do—you actually do it, with support.
One Big Takeaway
If you remember only one thing, let it be this: transforming your health after 50 as a Christian is not about chasing youth; it’s about stewarding the body you have, in partnership with God, using simple daily choices that work with your season of life—not against it.
Your body is not your enemy. Your age is not a curse. With a renewed mind, metabolic support, gentle detox rhythms, and God’s grace, you can feel lighter, clearer, and more available for the good works He still has for you.
