Calories in versus calories out, counting calories and what calories should be designated to specific macronutrient groups are all important terminology to be familiar with if you do have a developed interest into your own health and well-being. However I do feel the following information is extremely valuable if you have already familiarised yourself with the above.
1️⃣ Nutrient density.
In simple terms the nutritional density of a food refers to how nutrient rich a food actually is. I’m sure you’ve all heard of foods like Kale, Salmon, Coconut Oil and so on have been given the name “superfood” as they contain excessive amounts vitamins, minerals, antioxidants, amino acids and essential fatty acids. All of which are essential for the growth and maintenance of bones, muscles tissue and vital organs which is why you should have more of these foods in your everyday diet.
2️⃣ How much of each macronutrient do I need in order to achieve my goal. Depending on your long term fitness goal, be it losing weight or building muscle. The significance of each macro nutrient (carbs, fat and protein) can vary. For example if you are training to lose weight I would be of the opinion that lowering carbohydrates and increasing healthy fats and protein would be more optimal for this specific goal. But rather for building lean muscle tissue an increase in calories with high protein and moderate fat for a sustained period of time would be more applicable. .
3️⃣ Nutrient density vs calories in and calories out. As mentioned above about nutrient density, these foods are either whole foods, plants or gains. The idea that something like a protein bar, although it may advertise itself as a low carb, high protein and vitamin bar, is highly processed and is not a true replacement for another protein source like a peice of meat or poultry. However as I am an advocate of flexible dieting I would recommend opting for something like a protein bar as a substitute for confectionary or a chocolate bar, as you are at least reaping some reward for opting for the protein bar. .
