Nutrition Secrets from a Longevity Doctor

When it comes to longevity, nutrition is one of the most important levers we have.
But the truth is there’s no one perfect diet.

What matters most is that your nutrition supports your metabolism, your muscle, your gut, and your long-term health markers.

Here are the core nutrition principles we come back to again and again, whether you’re optimizing for energy, clarity, or decades of vitality.

1. Prioritize Protein

Most people don’t get enough high-quality protein.
And without it, your muscle declines, your metabolism slows, and your recovery suffers.

As a starting point, aim for 1.6 grams of protein per kilogram of body weight per day.
If you’re active, trying to build muscle, or over 40, you may need more.

Animal vs. Plant Protein

You don’t need to debate the perfect source but you do need to be informed.

• Animal protein typically offers all essential amino acids and tends to be more bioavailable.
• Vegan diets can work, but often require careful planning to avoid micronutrient deficiencies (like B12, iron, zinc, and omega-3s).

There’s no one right answer.
Choose the path that fits your values and your body but make sure you’re getting what you need.

2. Don’t Overlook Fiber

Fiber is not just about digestion.
It plays a major role in:

• Gut health and microbiome diversity
• Hormone balance
• Blood sugar regulation
• Detoxification pathways
• Lowering inflammation and cholesterol

Most people eat far too little.

Start with at least 25 grams per day, and gradually increase toward 40 to 50 grams especially if your gut can handle it.
Increase slowly to avoid bloating or discomfort.

Focus on whole food sources like:

• Vegetables
• Berries
• Chia seeds
• Lentils and beans
• Ground flaxseed
• Cooked and cooled starches like potatoes and rice

Fiber is one of the most overlooked longevity tools we have.

3. Know Your Sensitivities

Not every healthy food is healthy for you.

Food sensitivities can cause low-grade inflammation, fatigue, brain fog, joint pain, and bloating.
This is different from a food allergy, which causes an immediate and often serious immune response.

You can identify food sensitivities through:

• A supervised elimination diet (gold standard, but not easy to do alone)
• A food sensitivity panel via blood work (a good starting point for many)

Knowing your sensitivities helps you eat in a way that supports energy, digestion, and immune health.

4. Track Your Glucose Response

Two people can eat the same food and have completely different blood sugar reactions.
That’s why personalized tracking matters.

Using a continuous glucose monitor (CGM) or checking fasting insulin and post-meal glucose can give you insights like:

• Which foods spike your blood sugar
• How meals affect energy and mood
• How your body responds to stress, sleep, and exercise

You don’t need perfect numbers.
You need awareness and a plan that supports stable energy and lower inflammation.

5. Look at Your Labs

Nutrition isn’t just about what you eat.
It’s also about how your body is responding.

You should be tracking:

• ApoB – the most accurate marker of your cardiovascular risk
• LDL particle size and number – these matter more than total cholesterol
• Fasting insulin and glucose trends
• Inflammatory markers like hs-CRP
• Micronutrients if on a restrictive diet

If your labs are trending in the wrong direction, your “healthy” diet might not be working for you.

Final Thoughts

You don’t need to follow the trendiest diet or eliminate entire food groups.
But you do need to be strategic.

The best nutrition plan is:

• Protein-forward
• Fiber-rich
• Personalized to your labs, goals, and sensitivities
• Designed to support muscle, metabolic health, and longevity

At Ace Longevity, we help you figure out what works for your body—not just what works in theory.

Because the goal isn’t perfection.
The goal is progress that lasts.
