Age Better. Stay Strong. Keep Your Mind Sharp.
You don't have to accept the energy loss, weight gain, and mental fog that many people assume come with aging. I help adults in their 40s, 50s, 60s, and 70s and beyond restore their energy, maintain their strength, and support long-term brain health through evidence-based nutrition, lifestyle changes, and practical recovery approaches that fit real life.
Age Better. Stay Strong. Keep Your Mind Sharp.
You don't have to accept the energy loss, weight gain, and mental fog that people assume come with aging. I help adults in their 40s, 50s, 60s, and 70s feel more energetic, stay strong, and protect their brain health using evidence-based nutrition, lifestyle changes, and recovery strategies that work in the real world.
The Outcome That Matters Most: Getting Your Life Back.
Not a different life. Not someone else's life. Their life.
The energy they remember having. The ability to move without pain. Clear thinking. The confidence that they're not on a downward slide.
That's what keeps people committed to the process. They stick with it because it works.
And here's what happens:
Most people notice more energy within 3–4 weeks. Around 6–8 weeks, clothes begin fitting differently. Sleep improves. Brain fog lifts. They start feeling like themselves again.
Just as important, they understand why these changes happen. They can see the connection between what they're doing and how they feel. They trust the process because it's grounded in rigorous research and human biology—not opinions, trends, or influencer hype.
That understanding changes everything.
It’s what turns short-term progress into lasting results.
The Foundation:
I've spent 25+ years researching how to slow biological aging and keep people strong and sharp as they get older. My work has been published in the New England Journal of Medicine, JAMA, and the American Journal of Clinical Nutrition. But what really matters is translating these scientific discoveries into practical strategies that work for real people, strategies you can use right now, at home, at work, in your daily life.
This is science translated into daily decisions that compound over time.
What's Really Motivating You To Change?
You're probably tired of:
Waking up without energy or hitting an afternoon slump
Struggling with weight gain despite eating “healthy”
Brain fog and difficulty focusing
Joint pain and stiffness that makes you avoid exercise
Fear that you're losing your strength and independence
Conflicting health advice everywhere you look
Poor sleep and slow recovery
The real problem:
You don't need another fad diet or wellness gimmick. You need a clear, science-backed approach that respects your intelligence and actually fits your life.
That's where I come in.

Signs of Autophagy: 5 Ways to Tell If Your Autophagy Process Is Active
Autophagy, which technically means self-eating, is an “evolutionary conserved process” through which our cells remove waste products and damaged particles.
When we accumulate damaged particles and waste products, they must be removed so that our cells can function more efficiently.
Almost all cells use this process for survival and ultimately for growth. For this reason, some call the process of autophagy the “fountain of youth.”
While this is an amazing process, in order to make sure it is working in our bodies, it is important to understand the signs of autophagy.
First, let’s learn a little more about autophagy, and then we will cover a few areas that can help you identify if autophagy is active in your body.
Table of Contents
Does Flipping the Metabolic Switch Activate Autophagy?
What Exactly Is Autophagy?
In simple terms, you can think of autophagy as your body’s way of taking out the trash. First, you put trash or waste in a trash bag, and when it is filled up you take it outside where it is eventually taken away.
In a very similar manner, your body traps waste products in little bags within your cells and then takes these waste bags into the bloodstream to be removed. Research over the past few decades has revealed how critical the process of autophagy is to our health.
Autophagy Creates Healthier Cells
Once your body has properly removed waste products, your cells can function more efficiently. Healthier cells produce less free radicals and inflammation (aka the bad guys) and more energy.
With less of the “bad guys” around, the body can use more of its resources to repair and recover instead of fighting the “bad guys.” Ultimately, your body will function more efficiently and effectively in every way.
When Does Autophagy Occur?
Autophagy occurs when we are in an energy deficit and our metabolic switch is flipped.
Flipping the metabolic switch occurs when our bodies expend glucose reserves and start using ketones, or our body fat, for energy.
Autophagy Main Triggers
Energy deficits, particularly sustained energy deficits, which are achieved while we are sleeping and/or practicing intermittent fasting or exercising for prolonged periods, are the primary triggers for autophagy.
Unfortunately, most people do not engage in lifestyles that produce temporary energy deficits sufficient to flip their metabolic switch, so that they are using ketones as a primary fuel source.
Without these temporary energy deficits, our body remains in the fed state and never quite achieves the fasted state required for autophagy to properly do its job.
Does Flipping the Metabolic Switch Activate Autophagy?
The short answer is yes.
When we fast for 12 or more hours or exercise for a prolonged period, we are able to flip our metabolic switch and shift our body’s energy source from glucose to ketones.
This has a very positive effect on the function of our mitochondria (energy producing molecules in the cell) and also activates the process of autophagy.
The switch is flipped in response to the temporary stress of low nutrient availability/intake (aka fasting) over a period of time.
The time frame is generally at least 12 hours and is considered a “hormetic response,” meaning it produces beneficial effects (e.g., improved health, increased stress tolerance, enhanced health-span) following the temporary stress.
The exact amount of time it takes to activate the metabolic switch depends on several factors, including an individual’s metabolic flexibility and the amount of energy expended during the fasting period.
Signs Your Metabolic Switch Has Been Activated:
You are very comfortable fasting for at least 12 hours
None or only minor feelings of hunger while fasting
Great focus and mental clarity
Energized yet calm feeling
Absence of headache, dizziness, and light-headed feelings
Once activated, it is important to not allow the body to go into “starvation mode,” as this may have negative effects on your metabolism and muscle mass.
5 Potential Signs of Autophagy
At this point in time, there is unfortunately no easy way to measure autophagy in humans. We do not have a universally recognized marker of autophagy or a test that can tell you your levels of autophagy.
Additionally, while autophagy is generally health promoting for the vast majority of people, it can in some instances be harmful if left unchecked. It’s all about balance.
If you have been diagnosed with Diabetes or are prone to hypoglycemia, it’s best to consult your physician before increasing the number of hours of fasting.
Taking these considerations into account, below are five potential indicators of amplified or enhanced autophagy:
1. Extra Bowel Movements
We all recognize that bowel movements are one of the main ways our body removes waste products.
For this reason, one sign of enhanced autophagy that almost no one talks about is increased bowel movements, specifically having an “extra” bowel movement during the fasting period.
Generally, one should feel better after the bowel movement, meaning more alert, focused and energized.
This insight came to me from both personal experience and speaking with friends and patients over the years about their experience during the fasting period.
2. Eye Debris
Another sign of autophagy taking place can be found in the eyes. We all have likely experienced debris around the eyes upon awaking from a deep sleep.
This “debris” is a combination of mucus, oil, skin cells and other waste products that accumulate in the corner of your eye while you sleep.
The same process occurs while we are fasting and may be amplified if we do certain activities, such as meditating, in the fasted state.
3. Musculoskeletal Releases
Yet another subtle sign that I believe is related to autophagy taking place within the body are spontaneous muscle releases or energetic impulses that occur during a fasting time-period.
Typically, the longer the fasting period, the more likely the releases are to happen.
4. Metallic Taste
Another possible sign of an activation of autophagy is a change in breath smell to a more “metallic” scent due to the ketosis process that happens when autophagy increases.
The ketone type that mainly causes this odor is called acetone and can be avoided by brushing your teeth or chewing gum.
5. Mild Hunger
For most people, the process of flipping the metabolic switch involves tolerating mild to moderate levels of hunger initially.
Over time, a reduced appetite may represent a sign of enhanced autophagy due to the effects lower glucose levels have on the hormones of glucagon and insulin.
Signs of Autophagy Summary
Until recently, the importance of autophagy for our health has not been well understood, which is somewhat surprising given its primary importance to cellular health and survival.
When autophagy is working properly, it not only improves cellular health but can have a positive effect on all areas of our body.
The five signs of autophagy outlined above can serve as a guide to help determine if this life sustaining process is working for you.
In addition to these signs, amplifying autophagy should ultimately provide an energy boost and may also lead to improved mental clarity.
If you do notice a few of the above signs, sit back and enjoy, as the process of autophagy is more than likely active and the full body benefits should follow shortly after.
Helping You Age Better
I've organized everything I offer around five core areas. You probably need help in more than one of these areas - most people do. The good news is if you improve in one area, you are likely to see improvements in other areas.
More Energy & Better Metabolism
You want to wake up ready to go, not drag through the day. This is about optimizing how your body processes food and fuel. Better metabolism means better energy, easier weight control, and stronger physical performance.
Purpose & Peace of Mind
Physical health is part of the equation. So is feeling like you're in control of your future, living with purpose, and knowing you're doing the right things at the right times.
Stay Strong & Move Without Pain
Maintaining muscle, balance, and mobility is what allows you to live a full life and stay independent as you age. Whether it’s hiking, skiing, playing with your kids (or grandkids) or just moving through your day without stiffness - this matters.
Recovery & Physical Resilience
Your body needs proper recovery to stay healthy. This includes good quality sleep, stress management, and movement strategies that help you bounce back faster.
Brain Health & Sharp Thinking
Protecting your brain and maintaining your mental clarity as you age isn't something that happens by accident. It requires specific nutrition, sleep habits, movement, and lifestyle strategies specific to brain health. I'll show you exactly what works.

What the Research Actually Shows
I don't make health claims based on guessing. Everything I recommend is backed by clinical research, (studies conducted on real humans). Here's what decades of studies show:
On Intermittent Fasting and Eating Patterns:
Properly designed fasting protocols can improve metabolic health, support weight loss, and protect brain function. But there's a right way and a wrong way to do it.
On Metabolism as You Age:
Yes, metabolism typically slows with age, but it doesn’t have to change that much. Muscle mass, nutrition, meal timing, and movement patterns can all help you maintain a healthy metabolism as you age. You have more control than you think.
On Brain Health and Aging:
Your lifestyle choices, including sleep, nutrition, movement, brain training, and stress management, directly impact your risk of cognitive decline. Protecting your brain health is one of the most important things you can do, and it’s never too soon to start.
On Staying Strong and Independent:
Resistance training, proper nutrition, and recovery aren't optional as you get older. They are the key factors that determine if you stay strong and resilient as you age or not. It's not too late to start.
Individual results vary, but these principles are consistently supported across large clinical trials and long-term studies.
