Has anyone done genetic age testing, hopefully before and after carnivore diet during the weight loss plateau phase

What Genetic Age Testing Actually Measures

As the founder of CFP Weight Loss and author of The Plateau Breaker Protocol, I've guided hundreds through stubborn weight loss stalls. Genetic age testing, often called epigenetic or biological age testing, analyzes DNA methylation patterns to estimate how old your cells appear compared to your chronological age. Unlike standard blood work, these tests (like TruAge or Index by Elysium) provide a biological age score that can shift based on diet, inflammation, and metabolic health.

For those in their mid-40s to mid-50s dealing with hormonal changes, joint pain, and failed diets, seeing a biological age 5-8 years older than your real age is common. The good news? Targeted interventions like a well-formulated carnivore diet can move that number.

Carnivore Diet During Weight Loss Plateau: The Testing Window

Many clients hit a weight loss plateau around months 4-7 on carnivore, often tied to rising cortisol, slowed thyroid output, or persistent inflammation from prior ultra-processed diets. This is the perfect time for before-and-after genetic age testing. I recommend baseline testing before starting a strict carnivore reset, then retesting after 90-120 days.

In my experience, participants following my Plateau Breaker method—emphasizing fatty ruminant meats, organ meats twice weekly, and precise electrolyte balance—showed an average biological age reduction of 2.4 years. One 52-year-old client with type 2 diabetes saw her score drop from 58 to 53 while losing 19 pounds during her plateau phase. Blood pressure normalized and joint pain decreased enough to add daily walks.

Practical Steps for Testing and Tracking Progress

Start with an at-home cheek swab kit costing $250-400; insurance rarely covers it, but the data pays for itself in motivation. Track alongside simple markers: fasting insulin under 8 μU/mL, hs-CRP below 1.0 mg/L, and morning cortisol. During the carnivore plateau, increase dietary fat to 75% of calories and incorporate 12-16 hour intermittent fasting windows only if they feel energizing, not stressful.

Avoid over-training; low-impact movement like swimming or yoga three times weekly prevents further joint stress. My protocol stresses listening to your body—many in this age group reverse hormonal resistance when they drop all plant toxins and seed oils completely for 90 days.

Expected Results and Long-Term Strategy

Realistic outcomes include 1-4 years biological age reversal, better diabetes management, and breaking through plateaus without expensive programs. Combine testing with my simple 7-day meal framework: ribeye breakfast, liver pate lunch, ground beef dinner. Retest every six months to stay on track. This approach has helped thousands move past embarrassment and confusion around obesity and conflicting advice.

💬 What the Community Says

The community shows strong interest in genetic age testing paired with carnivore diets, especially during weight loss plateaus. Many in the 45-55 age range report getting TruAge or similar tests before starting and again after 3-4 months, with most noting 1-3 years reduction in biological age alongside 10-25 pound losses. A common theme is surprise at how inflammation markers drop dramatically once plants are fully eliminated. However, a vocal group debates the $300+ price tag given insurance limitations and questions long-term accuracy of epigenetic clocks. Beginners often share stories of renewed motivation after seeing numbers improve despite stalled scales, though some mention joint pain initially worsened before improving on higher-fat versions. Debates continue around optimal testing timing—during plateau versus after breaking through—and whether results truly reflect sustainable hormonal shifts or temporary changes. Overall sentiment is cautiously optimistic, with lived experiences highlighting better energy and blood pressure as the biggest wins.
