What is L-Carnitine?


L carnitine is a compound naturally produced in our body and is involved in energy metabolism, by transporting long-chain fatty acids into mitochondrial cells in our muscles for energy production.


Because of its role in energy metabolism, it has been on retail shelves for many decades promoted as a ‘fat burner’’. This supplement is most popular in gyms as bodybuilders and fitness enthusiasts worldwide try to get a leaner and more ‘toned’ look coming towards the summer.


What is the theory?


Owing to the metabolic duties of L-carnitine stated above, the general advice from your average gym-joe is to consume 12g of L-carnitine a day, over 2-3 doses, combined with a vigorous resistance training protocol and low carbohydrate diet.


I tried it out, and it worked Jay!


Yes, if you did exactly as our famed gym joe told you then well done! He gave you good advice, but did you lose weight BECAUSE of L-carnitine? or was it because of the low-carbohydrate diet and intense training sessions?

Theoretically, if I combine a vigorous training program with a low-carbohydrate diet and have malt-vinegar with my coffee every morning, can I go out and preach how malt vinegar with coffee is God’s secret to fat loss?


My question is...

What does the research say?


Despite widespread interest among the fitness community to use L-carnitine for improvement of exercise performance and/or bodyfat percentages, there is a narrow array of research studies assessing the long-term effects of L-carnitine whilst controlling for diet and exercise. The research that does consider these factors, prohibits any substantial conclusion from being met regarding the positive effects of L-carnitine in exercise.

So what now?


Stop believing what person X tells you, do the research yourself through scientific studies found on Google Scholar or PubMed and find out, and if there’s a clear lack of research then you ask yourself, “If there’s no research, how does X know that this works?”

Is Breakfast Truly the Most Important Meal of the Day? Should you eat breakfast to achieve your fitness goals, or could skipping it be more beneficial? I aim to challenge conventional fitness advice when necessary to deliver the best results for my clients. My commitment to tailoring fitness solutions to individual needs is what sets me apart in the personal training industry. In a world dominated by one-size-fits-all approaches, it’s critical to remember that the most important person in any fitness journey is the client. Forcing a rigid mindset on someone often leads to frustration and failure, pushing them away from their goals. For many, breakfast has long been considered a non-negotiable meal. Decades of marketing by the breakfast cereal industry have ingrained the belief that starting the day with a bowl of sugary cereal is essential. For these individuals, switching to a healthier option—like grilled salmon and vegetables—can feel revolutionary. But what if you don’t enjoy breakfast? What if skipping it altogether makes you feel better? The Breakfast Myth: Science vs. Belief For years, health experts have drilled into us that skipping breakfast is a fast track to obesity and chronic disease. The phrase “breakfast is the most important meal of the day” is so entrenched in society that questioning it seems almost heretical. Interestingly, a recent meta-analysis of breakfast-related studies found that the belief in breakfast’s benefits often outweighs the strength of scientific evidence. Researchers uncovered significant biases in how results were interpreted, leading to conflicting conclusions. Does this mean breakfast is bad? Absolutely not. Instead, it highlights the need for an open-minded approach to nutrition, prioritizing what works best for you. While nutrition debates can be divisive, achieving body composition goals ultimately boils down to three basics: creating a calorie deficit, eating nutritious foods, and sticking to the plan.

Through my experience as a Personal Trainer, I have observed the patterns, themes, and trends in a manner by people ive spoken to and worked with. A singular, unifying catalyst for successful weight-loss narratives exists: the moment of realization, an epiphany, the "Aha, I can’t continue this way." This is precisely why the 'healthy at every size' ideology is flawed. You are not healthy at every size. "But one can be ill and underweight too," they retort. Indeed, that is possible, yet it’s merely deflection. The focus here is not on anyone else. If one is overweight, the probability of death escalates. The greater the excess weight, the higher the propensity for illness and the decline in life quality. This is an irrefutable truth, regardless of how anyone attempts to spin it. The term ‘morbid obesity’ (morbid, implying death) exists for a reason.
