• What food to eat
• How much to train
• What type of training
We go through so much trouble to measure our progress but why do we estimate our starting point? Simply put if we do not know how our metabolism is functioning the how can we decide which path is best for us? If we are not very efficient users of fat, then will eating a low carb high fat diet really work for us, or will it cause more harm than good? If our bodies become more efficient at the work, we are demanding of it, will that lower our calorific output, and stall our weight loss? If our metabolic rate is lower than expected, then will we still lose weight on a simple 500kcal drop of our estimate? Test don’t guess is the answer, discover exactly what you need to eat and how you need to train for an optimal you, without the pain of trial and error.
Metabolic efficiency indicates the portion of the chemical energy burnt (i.e. caloric expenditure measured by PNOĒ) that is converted to mechanical power (i.e. movement measured through a power meter). Metabolic efficiency is the most fundamental metric for every athlete as it pertains to the most core performance element; that is “how long will energy reserves last based on the current exercise intensity”. For example, the triathlete with the highest metabolic efficiency will most likely win the race. Moreover, it is highly essential for weight loss, since it is a measure of how much energy (i.e. calories) the body will consume during movement. The notorious “weight loss plateau” is caused by an increase in efficiency; that is burning less energy for the same level of activity. The human body operates in many ways just like a car which converts ~35% of its chemical energy (i.e. gas) to mechanical work (i.e movement) while the rest dissipates as heat.
Fat burning efficiency refers to our body’s ability to utilize fat rather than carbohydrates as a primary fuel during rest and exercise. The more “metabolically fit” we become, the more our body learns to utilize fat as a source of fuel throughout the day. Increased fat burning efficiency is associated with low probability of weight gain or weight regain in the case of a prior weight loss attempt. Moreover, it is associated with increased performance in endurance sports and physical exercise in general.
Cardiorespiratory Fitness is the ability of the heart, blood cells, and lungs to supply oxygen-rich blood to the muscles and the ability of the muscles to use oxygen to produce energy for movement. According to the American Heart Association, Cardiorespiratory Fitness constitutes the strongest predictor for overall and cardiovascular mortality, stronger than any other risk factor including hypertension, smoking or cholesterol. According to the American Heart Association, cardiovascular fitness is associated with reduced blood pressure, reduced risk of developing coronary heart disease, lower incidence of diabetes, and decreased risk of stroke and heart attack. It is highly essential for your wellbeing to maintain it at high levels.
