The misuse of fasted training

The line separating fasted workouts from disordered eating can become blurry for athletes. Proponents claim that fasted workouts have several significant health and performance benefits. The main reasons why athletes perform fasted training include: Increasing the rate in which your muscles use fat for fuel  Sparing glycogen stores   Increasing mitochondrial density Fat oxidation refers to the process of breaking down fatty acids. To oxidize fat, you need:  Healthy mitochondria (the powerhouse of cells where chemical energy is generated to power the cell's biochemical reactions).  Fat molecules (specifically triglycerides) to be broken down into glycerol and fatty acids. Fatty acids are then transported to cells and undergo a series of reactions (beta-oxidation) to produce acetyl-CoA to enter the citric acid cycle to generate energy. Oxygen (transported to the muscles by blood). Fat cannot be burned (or oxidized) without the presence of oxygen.  While there...

Is fat burning undermining your performance?

Source The media loves to make nutrition simple. Workout fasted and you burn more fat. If only it was this simple.  When it comes to the physiology of the body during exercise, nutrition is a complex topic. Researchers are still studying the different effects of nutrients, nutrient timing and supplements on exercise and exercise performance. This isn't to say that fat burning doesn't work (it does!) but it's not as simple as not eating carbohydrates before and during a workout.  There's a lot of debate about fasted training, training low, LCHF diets, keto and low carb. Unfortunately, with no middle ground, athletes tend to direct their energy and attention to what's most trendy and popular and for the past few years, carbohydrates have received a bad reputation from the media.  I am a proponent of carbohydrates in the diet. I feel strongly for nutrient timing (eating before/after workouts) and I believe that the use of sport nutrition is critical in optimizing healt...

Athletes - be careful of trending diets

It seems like fasting is all the rage these days. Although not a new concept for athletes (fasted workouts have been studied by researchers for several decades), not eating has grown in popularity over the years as a way to enhance and optimize fat burning and to promote weight loss. There's also the claim that fasted training can improve athletic performance in endurance athletes - although according to consistent research, that doesn't appear to be the case. One of the major reasons for a massive shift in how athletes eat is an overwhelming obsession with energy, performance and body image. Athletes are also hungry for direction, guidance and quick fixes. In addition to fasted training and intermittent fasting, there is a wide spectrum of diet ideologies these days - ketogenic, vegan, clean eating, Gluten free and Paleo to name a few. What's interesting is the culture around these diets and their "communities." The dieting behaviors embraced by follow...
