Mitochondrial dysfunction feeds chronic pain when mitophagy, the system your cells use to recycle damaged mitochondria, falls behind. The “zombie” mitochondria that pile up leak reactive oxygen species (harmful oxygen by-products). These feed inflammation and block new energy production. Constant eating keeps the mTOR signal stuck on, and that jams the cleanup. So meal timing is a key lever.
If it feels like your body has lost the power to renew and repair itself, this article is for you. Dr. Padda explains how your cells recycle damaged mitochondria. The quality-control system is called mitophagy. He also explains what happens to your pain when that cleanup crew falls behind. The hopeful part: the renewal machinery isn’t gone. It’s swamped. And much of what swamps it comes down to how and when you eat.
How do your cells recycle damaged mitochondria?
Healthy cells run a smart recycling process called mitophagy. Its job is to patrol your mitochondria and find the ones that are damaged or worn out. It walls them off and breaks them down for parts. That clears the way for healthy new mitochondria to take their place. It is quality control inside the cell, and it is essential. As long as mitophagy runs well, your mitochondria stay clean and efficient, and the system renews itself.
Why do 'zombie' mitochondria cause pain?
In many chronic pain patients, this cleanup is swamped or hijacked. When mitophagy can’t keep up, damaged units stick around. They become what Dr. Padda calls zombie mitochondria. These are not harmless. They pile up more damage. They leak too many reactive oxygen species, which feed the inflammation loop. They can even trigger cell-death signals. There is also a catch-22. If you cannot clear the damaged units, you cannot make room to rebuild healthy energy production. The broken power plants clog the factory floor, so no new ones can go in. The cell sinks deeper into energy crisis and inflammation.
What eating pattern blocks your cells' cleanup?
One key factor is a signaling pathway called mTOR. It is a grow-and-build signal. It matters. But when it stays switched on all the time, it shuts down the cell’s cleanup. That includes the autophagy (the cell’s self-cleaning) that mitochondrial renewal depends on. What keeps mTOR jammed on? Among other things, a constant stream of extra fuel. High glucose, constant eating, and never fasting mark much of the modern diet. The same eating pattern that drives inflammation and insulin resistance can also keep the grow signal stuck on. So your cells never get the signal to stop building and start recycling.
How do we fix mitochondrial dysfunction at the Padda Institute?
Dr. Padda’s approach is to restore healthy quality control inside the cell. A key lever is eating patterns planned for each person. These include the right periods of metabolic rest. Rest eases the stuck-on mTOR signal and lets autophagy and mitophagy run again. Then cells can clear out damaged mitochondria and grow healthy ones. We also work to cut the metabolic overload and inflammation that swamp the system. This is a practice-based approach tailored to each person, not a fixed prescription. How and when you eat drives much of this state. So you have real power to change it. Individual results vary.
Frequently asked questions
What is mitophagy and why does it matter for pain?
Mitophagy is your cells' recycling system. It clears out damaged or worn-out mitochondria so healthy ones can take their place. When it is swamped, damaged 'zombie' mitochondria pile up. They leak reactive oxygen species and block new energy production. That feeds the energy crisis and inflammation seen in chronic pain. Restoring that cleanup is a core aim of the approach.
For how cells build the new mitochondria that replace the ones cleared away, read PGC-1 Alpha: The Master Switch for Building the Energy to Heal.
What are 'zombie' mitochondria?
Zombie mitochondria are damaged power plants that stick around because the cell's cleanup crew (mitophagy) has fallen behind. They do not sit quietly. They pile up more damage and leak too many reactive oxygen species, which fuel inflammation. They can trigger cell-death signals. And they crowd out healthy new mitochondria.
Should I try fasting to fix this myself?
Here, periods of metabolic rest are planned for each person and used with care. They are not a one-size-fits-all fast you should start alone. Fasting can be unsafe for some people and can interact with medications. Do not start, stop, or change any medication or fasting or eating plan without consulting your physician. Individual results vary.
What is mitochondrial dysfunction?
Mitochondrial dysfunction means your cells can no longer make clean, steady energy. In chronic pain, a common reason is that mitophagy falls behind. That is the cleanup system that recycles worn-out mitochondria. Damaged units pile up and leak reactive oxygen species that feed inflammation. They take up the space healthy new mitochondria need. The cell slides into an energy crisis. That crisis feeds the inflammation loop behind your pain.
Can mitochondrial dysfunction be reversed?
Yes, for many people. The renewal machinery is not gone. It is swamped, and much of what swamps it comes down to how and when you eat. Eating patterns built for you, with planned periods of metabolic rest, calm a stuck-on mTOR signal. That lets autophagy and mitophagy restart. This is a practice-based approach tailored to each person, and individual results vary.
How can I help my body make new mitochondria?
Start by clearing out the broken ones. A cell cannot install new power plants while damaged ones clog the factory floor. When constant eating keeps mTOR stuck on, the cell stays in grow mode. It never switches to recycling. Periods of metabolic rest let the cleanup run. That clears room for healthy mitochondria to grow back. Do not start a fasting plan without talking to your physician.

Key takeaways
- Mechanism: when mitophagy is swamped, damaged 'zombie' mitochondria pile up and block clean energy production.
- Evidence status: mitophagy, autophagy, and mTOR's role are described as well established, including Nobel-recognized work.
- Why timing matters: constant eating keeps mTOR stuck on, and that shuts down the cleanup your cells need.
- Next step: eating patterns built for you, plus metabolic rest, may restart renewal. Book at painmd.tv/appointment/.
