Cells make new mitochondria and clear out old or damaged ones. This keeps mitochondria healthy and plentiful, which helps the body burn fats and carbohydrates for energy more effectively.
See the scientific wording
Mitochondrial biogenesis and mitophagy increase the number and quality of mitochondria, thereby enhancing the metabolic capacity for oxidation of fatty acids and carbohydrates.

What the research says
2 studies reviewedSupporting (2)
Randomized Controlled TrialAnimal
The study shows that a special treatment makes cells recycle damaged mitochondria and make new ones, which helps them produce more energy. This supports the idea that having healthier mitochondria helps the body burn fuel better.
Cross-Sectional StudyAnimal2005
The study shows that making more mitochondria (by increasing a protein called PGC1alpha) helps cells burn fat better, which supports the idea that having more mitochondria helps burn fat and carbs.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
The body makes more mitochondria and cleans out the old broken ones. This gives cells more energy factories that work better, so they can burn fats and sugars more efficiently.

Mechanism
2 studiesThe body makes more mitochondria and cleans out the old broken ones. This gives cells more energy factories that work better, so they can burn fats and sugars more efficiently. The treatment also calms down immune cells, which helps the energy factories work even better.
The body makes more mitochondria and cleans out the old broken ones. This gives cells more energy factories that work better, so they can burn fats and sugars more efficiently.
Signals from mitochondrial components activate the PI3K/AKT pathway, which upregulates the master regulator PGC-1α and key metabolic enzymes (PFKM for glycolysis, IDH2 for the TCA cycle).
PGC-1α drives mitochondrial biogenesis, increasing mitochondrial mass and mtDNA copy number, expanding the mitochondrial network.
PINK1/Parkin-mediated mitophagy selectively eliminates damaged mitochondria, reducing reactive oxygen species and preserving mitochondrial integrity.
The increased number and quality of mitochondria enhance oxidative phosphorylation and glycolysis, boosting ATP production and the capacity to oxidize fatty acids and carbohydrates.
Less supported by current evidence, but not ruled out
The treatment also calms down the immune cells, making them release anti-inflammatory signals that help the body's energy factories work better.
Mitochondrial components from the treatment induce macrophage polarization from pro-inflammatory M1 to anti-inflammatory M2 phenotype.
M2 macrophages secrete anti-inflammatory cytokines, reducing oxidative stress and creating a favorable environment for mitochondrial function and metabolic activity.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of Interventions Enhancing Mitochondrial Biogenesis and Mitophagy on Metabolic Capacity
Comprehensive search of RCTs and controlled trials that measure mitochondrial markers (e.g., mtDNA content, protein levels) and metabolic flexibility (e.g., respiratory exchange ratio, substrate oxidation rates) in response to interventions like exercise, caloric restriction, or pharmacological agents.
Randomized Controlled Trial of Endurance Exercise Training on Mitochondrial Biogenesis and Metabolic Capacity
Sedentary adults randomized to 12 weeks of supervised endurance exercise vs. control (no exercise). Pre- and post-intervention muscle biopsies to measure mitochondrial content (citrate synthase activity, mtDNA copy number) and respirometry to assess fatty acid and carbohydrate oxidation rates.
Prospective Cohort Study of Physical Activity Levels and Mitochondrial Function in Adults
Follow a cohort of adults with varying self-reported physical activity levels for 5 years. At baseline and follow-up, measure mitochondrial markers (e.g., muscle biopsy, blood biomarkers) and metabolic outcomes (e.g., VO2max, insulin sensitivity, substrate oxidation).
In Vitro Study of Mitophagy Induction on Mitochondrial Quality and Fatty Acid Oxidation in Cultured Myotubes
Cultured human or rodent myotubes treated with mitophagy inducers (e.g., rapamycin, urolithin A) or genetic manipulation (e.g., overexpression of PINK1/Parkin). Measure mitochondrial mass, membrane potential, reactive oxygen species, and oxygen consumption rates (OCR) for fatty acid and carbohydrate substrates.
