Another new week starts.

How are we all doing on that most wonderful of days - Monday.....?

Ok, that was mostly sarcasm.

But Monday doesn't have to be MoanDay. Hey. I'm an actual genius, right? That just popped into my head.

I know I'm very lucky to be early retired, at least for now (I may have to go back to work eventually for morbid reasons, but that's another conversation, lol).

But when I was working up to last year, I had a pretty intense daily work life, and I still did my best to appreciate every day, no matter what particular day that was.

But anyway, my Monday morning so far has been positive.

Sleep? Don't be silly. Mucus? Yeah, I don't wanna talk about it. Insulin pump efficiency? Ha, nope. Getting there, though.

Oops, this is turning into one of my essays.....Reel it in, woman!

So even with all that nonsense going on, I'm on with life.

Right. On with my day......

Up before six. Out for my 30 minute walk. An early one, but I'm happy with that. Great way to wake everything up.

Upper body/ab workout soon after gettinghome.

I like this one. Not done it for a long while according to the app data.

I then got my Monday house chore put of the way. Cleaning the bathroom (no pic of that, haha), then time to sit on the floor by the big window for breakfast.

Favourite time of day. I love my frothy collagen/inulin decaff filter. And I have found I love breakfast, no matter what changes I keep having to make. Tomorrow will be keto porridge made with coconut "flour", cashew butter, frozen blueberries and more collagen.

I had to get moving again, as my blood sugar was running way too high this morning. It had actually been settling down, so that was a curveball. I thought it was possibly a faulty insulin pod.

I haven't done anything for my YouTube channel for ages, so I got on with a HIIT workout. Takes longer to upload than it does to actually do the workout 😅.

Monday's fitness ended with lower body pilates.

Before starting that, my blood sugar went in the exact opposite direction, so obviously not a pod issue. Just a, y'know.....ME issue, lol.

Anyway, meh to all of that. I feel good.

Basic 15hr fast as usual. Same high quality food as usual, and a good, positive day all round.

Hooray for a happy Monday 😊.

Mitochondrial Dysfunction in Type 2 Diabetes

Introduction

Mitochondria, essential for cellular energy metabolism, play a crucial role in bioenergetics and metabolic homeostasis. Mitochondrial dysfunction has been implicated as a key pathophysiological factor in Type 2 Diabetes Mellitus (T2DM), contributing to insulin resistance, metabolic inflexibility, and beta-cell dysfunction. This review explores the intricate mechanisms underlying mitochondrial impairments in T2DM, including defective oxidative phosphorylation, disrupted mitochondrial dynamics, impaired mitophagy, and excessive reactive oxygen species (ROS) generation, with a focus on potential therapeutic interventions targeting mitochondrial pathways.

Mechanistic Insights into Mitochondrial Dysfunction in T2DM

1. Defective Oxidative Phosphorylation and ATP Synthesis

Mitochondrial oxidative phosphorylation (OXPHOS) occurs through the electron transport chain (ETC), comprising Complexes I-IV and ATP synthase (Complex V). In T2DM, evidence suggests a downregulation of mitochondrial ETC activity, particularly in Complex I (NADH:ubiquinone oxidoreductase) and Complex III (cytochrome bc1 complex), leading to reduced ATP synthesis. This dysfunction is often linked to compromised NADH oxidation and inefficient proton gradient formation, resulting in cellular energy deficits and impaired insulin-stimulated glucose uptake.

2. Elevated Reactive Oxygen Species (ROS) and Oxidative Stress

Mitochondria are a primary source of ROS, predominantly generated at Complex I and Complex III during electron leakage. In T2DM, excess substrate influx due to hyperglycemia leads to mitochondrial overactivation, driving excessive ROS production. Elevated ROS induces oxidative damage to mitochondrial DNA (mtDNA), lipids, and proteins, disrupting mitochondrial integrity and function. Oxidative stress further impairs insulin signaling by activating stress-responsive kinases such as c-Jun N-terminal kinase (JNK) and IκB kinase (IKK), contributing to systemic insulin resistance.

3. Mitochondrial Biogenesis and Transcriptional Dysregulation

Mitochondrial biogenesis is regulated by the transcriptional coactivator Peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1α), which modulates downstream transcription factors such as Nuclear Respiratory Factors (NRF-1/NRF-2) and Mitochondrial Transcription Factor A (TFAM). In T2DM, PGC-1α expression is downregulated, impairing mitochondrial biogenesis and reducing mitochondrial density, leading to decreased oxidative capacity in metabolically active tissues like skeletal muscle and liver.

4. Disrupted Mitochondrial Dynamics and Mitophagy

Mitochondrial quality control is maintained through dynamic fission and fusion processes. Fission, mediated by Dynamin-related protein 1 (Drp1), is necessary for mitochondrial fragmentation and mitophagy, while fusion, regulated by Mitofusin 1/2 (Mfn1/2) and Optic Atrophy 1 (OPA1), maintains mitochondrial integrity. In T2DM, an imbalance favoring excessive fission leads to mitochondrial fragmentation, impairing energy metabolism and exacerbating insulin resistance. Moreover, defective mitophagy, regulated by PTEN-induced kinase 1 (PINK1) and Parkin, results in the accumulation of dysfunctional mitochondria, further aggravating metabolic dysfunction.

Implications of Mitochondrial Dysfunction in T2DM Pathophysiology

1. Skeletal Muscle Insulin Resistance

Skeletal muscle accounts for ~80% of postprandial glucose uptake, relying on mitochondrial ATP production for insulin-mediated glucose transport. Impaired mitochondrial function in muscle cells reduces oxidative phosphorylation efficiency, promoting a shift towards glycolysis and lipid accumulation, ultimately leading to insulin resistance.

2. Pancreatic Beta-Cell Dysfunction

Mitochondrial ATP production is essential for insulin secretion in pancreatic beta cells. ATP-sensitive potassium channels (K_ATP) regulate glucose-stimulated insulin secretion (GSIS), with ATP/ADP ratios dictating channel closure and depolarization-induced insulin exocytosis. In T2DM, mitochondrial dysfunction leads to inadequate ATP generation, impairing GSIS and reducing insulin secretion capacity. Additionally, oxidative stress-induced beta-cell apoptosis contributes to progressive loss of beta-cell mass.

3. Hepatic Mitochondrial Dysfunction and Lipid Dysregulation

Mitochondrial dysfunction in hepatocytes contributes to hepatic insulin resistance and non-alcoholic fatty liver disease (NAFLD). Impaired fatty acid oxidation due to dysfunctional mitochondria leads to lipid accumulation, exacerbating hepatic insulin resistance and systemic metabolic dysregulation.

Therapeutic Strategies Targeting Mitochondrial Dysfunction

1. Exercise-Induced Mitochondrial Adaptation

Physical activity upregulates PGC-1α expression, enhancing mitochondrial biogenesis and oxidative metabolism. High-intensity interval training (HIIT) and endurance exercise improve mitochondrial efficiency and reduce oxidative stress, mitigating insulin resistance in T2DM patients.

2. Pharmacological Modulation of Mitochondrial Function

Metformin: Enhances mitochondrial complex I activity, reducing hepatic gluconeogenesis and oxidative stress.

Thiazolidinediones (TZDs): Activate PPAR-γ, promoting mitochondrial biogenesis and improving insulin sensitivity.

Mitochondria-targeted Antioxidants: Agents like MitoQ, SkQ1, and SS-31 reduce mitochondrial ROS, preventing oxidative damage and preserving mitochondrial function.

3. Nutritional and Metabolic Interventions

Ketogenic and Low-Carb Diets: Enhance mitochondrial fatty acid oxidation, reducing lipid accumulation and improving metabolic flexibility.

Intermittent Fasting: Induces mitochondrial biogenesis and autophagy, improving metabolic homeostasis.

Nutraceuticals: Coenzyme Q10, resveratrol, and nicotinamide riboside (NR) enhance mitochondrial function and energy metabolism.

4. Emerging Gene and Cellular Therapies

Gene Therapy: Targeted upregulation of PGC-1α and TFAM to restore mitochondrial function.

Mitochondrial Transplantation: Direct transfer of healthy mitochondria to replace dysfunctional ones, an emerging frontier in metabolic disease management.

Conclusion

Mitochondrial dysfunction is a central determinant in the pathogenesis of T2DM, affecting insulin signaling, glucose metabolism, and lipid homeostasis. Targeting mitochondrial pathways through exercise, pharmacological agents, dietary modifications, and emerging gene therapies offers promising avenues for improving metabolic health in T2DM.

Hiit Classes Downtown Toronto - Church of Sweat

What are the disadvantages of HIIT workouts?

For most people, 2 to 3 HIIT classes per week is ideal. HIIT (high-intensity interval training) is highly effective, but it's also very intense and can be demanding on the body. HIIT workouts are highly effective but do come with some potential disadvantages:

Increased Risk of Injury: HIIT involves quick, intense movements, which can lead to injuries, especially if your form isn't perfect or if you're not accustomed to high-impact exercises. Beginners are especially susceptible if they jump into HIIT too quickly.

High Physical Demand: HIIT can be taxing on the cardiovascular system, muscles, and joints. This intensity can lead to fatigue, burnout, or soreness that might hinder consistent training, especially without adequate rest and recovery.

Not Ideal for All Fitness Levels: People with joint issues, cardiovascular concerns, or certain health conditions may find HIIT too strenuous. Lower-intensity exercises may be better suited to avoid undue stress on the body.

Mental Fatigue: The intense effort required can sometimes lead to mental burnout or dread, especially if you find HIIT sessions exhausting. This can make it harder to maintain consistency.

Limited Focus on Muscle Strength: While HIIT often involves bodyweight movements, it typically doesn't target muscle growth as effectively as dedicated strength training, potentially limiting gains in strength and muscle mass.

Recovery Time Required: Due to its intensity, HIIT requires ample recovery, making it difficult to do daily. Overdoing it without sufficient rest can lead to overtraining, injuries, and immune suppression.

Caloric Demands May Increase: HIIT can make you very hungry, as it burns a lot of calories quickly. For those managing weight, this could lead to a tendency to overeat if not careful.

Incorporating HIIT in moderation and balancing it with other forms of exercise (like strength training or steady-state cardio) can help maximize benefits while minimizing these drawbacks.

Today started with my usual 30 minute early walk. Dull and rainy fiest thing. The sun is shining now, though 🌞

Upper body strength workout when I got back home.

Another great Fiton routine.

Similar idea to the one I did yesterday.

Combination moves, giving a fabulous training session.

Then back outside for breakfast in that lovely sunshine.

I am back into my fasting routine. Just feels better.

Taking advantage of my current determination to get my mojo back at the moment.

So in the spirit of that, I then swept the house before getting back outside once again for one of my YouTube uploads. Cardio core today! Go on, why not, right? 😋👍.

https://youtu.be/PQM2cTwazaM?si=aKA2sw4x3qeBCsbg

Eaten really well, keeping on top of my personal dietary focus.

So lovely to eat lunch outside. I'm getting that fresh air and natural light as often as I can, now that spring is finally (mostly) here!

Then a little later, I chose pilates to finish today's fitness.

Another good day. Even after a particularly long, relatively sleepless night. And I'm going through a really bad mucus flare up phase. Ugh.

But still......

Nothing can hold me down for long. Nope. I'm stronger (and more stubborn) than that!
