Metabolic Damage and How to Work on Repair
Episode Summary
Cole Siefer hosts naturopathic physician Dr. Sasha Rose for a conversation about metabolic health, what it actually means, and how to work on repairing it. Dr. Rose defines metabolism as how each cell creates and uses energy, and explains that the body is constantly adapting to stress, sleep, nutrition, activity, and hormones rather than simply being broken. She walks through why fatigue, brain fog, and difficulty losing weight show up in roughly eight or nine out of ten patients, and why short conventional visits rarely have time to find the root cause. The discussion covers the major drivers of metabolic imbalance, including nervous system dysregulation, hormonal status, thyroid conversion, and blood sugar swings, and the role of cortisol in keeping the body in survival mode. Dr. Rose explains GLP-1 peptides, how they work, where people go wrong with dosing and lack of support, and why peptide sourcing matters. She describes advanced testing that conventional labs skip, including salivary cortisol mapping, comprehensive hormone and thyroid panels, inflammatory markers, and genetic tests like MTHFR. The episode closes with a case study of a pre-diabetic patient who lowered her A1C and lost weight through lifestyle changes.

Quotable Moments
“A lot of people come in and they kind of feel like my metabolism isn't working, like my metabolism is broken. And I think a reframe is sometimes important, that the human body is very intelligent and it's always trying to adapt and survive.”
“It's literally impossible to dive deeper into where is the metabolic imbalance, what is contributing to the metabolic imbalance, why are you fatigued, why do you have brain fog. There's just literally not the time, because that model is not designed around assessing root causes.”
“The body doesn't know the difference between the tiger that's chasing you and the chronic work stress that you deal with on top of taking care of aging parents and teenagers. Physiologically there's no difference.”
“If the thyroid is not working optimally at any stage in that whole pathway, then things are going to be sluggish. It's basically like walking around with weights around your ankles and you don't really know why.”
“Where you get them matters. So where they're sourced matters. When we recommend and prescribe peptides, we only get them through specific compounding pharmacies that have really tight quality control and standards built in.”

FAQ
Metabolic Health FAQ
Dr. Rose describes metabolic health as how your body, and really each cell, creates and uses energy. Metabolism is how the body generates and utilizes ATP, and it is heavily influenced by hormones, the nervous system, and the mitochondria inside each cell. When these factors are out of balance, people often notice fatigue, brain fog, and difficulty losing weight.
Conventional providers usually run basic labs like a complete blood count or comprehensive metabolic panel, and if results fall in the normal range they may say you are fine. Dr. Rose explains that visits averaging five to twelve minutes simply do not leave time to investigate where the metabolic imbalance is coming from. The conventional model is not designed around assessing root causes, even when the provider genuinely wants the best for you.
Chronic stress, anxiety, poor sleep, and past trauma can all dysregulate the nervous system and put the body into a survival state. Dr. Rose notes the body cannot tell the difference between a real threat and ongoing life stress, so cortisol becomes dysregulated and signals the body to conserve energy, lower metabolic rate, and hold on to fat. She adds that blood cortisol is only a snapshot, so a salivary test that maps cortisol across the day gives a clearer picture.
GLP-1 medications are a class of peptides, including tirzepatide and semaglutide, that mimic hormones in the gut, pancreas, and brain. Dr. Rose says they can help with weight, blood sugar regulation, fatty liver, blood pressure, and inflammation when dosed appropriately for the right person. Problems usually come from doses that are too high, a lack of nutritional support, and not addressing the lifestyle pieces, which can lead to side effects or regaining weight after stopping.
Dr. Rose points to comprehensive hormone and thyroid panels that go beyond standard screening, plus inflammatory markers like HS-CRP, ESR, and homocysteine. She also uses salivary cortisol testing to map the daily rhythm, panels that assess nutrient levels and absorption, and genetic tests such as MTHFR and COMT. The goal is to look at whether levels are optimal, not just within the normal range.
Yes. Dr. Rose shares a case of a patient who learned on her initial blood work that she was in the pre-diabetic range. By cutting out sugar and processed carbs and recommitting to regular workouts, her hemoglobin A1C dropped on repeat testing and she lost about twenty pounds in three months. The example shows the value of testing, support, and personalized changes that meet a patient where they are.
