Protein: Myths and Reality

Whenever I get a new client and they are a few days “in”, eating a healthy diet and experiencing what it feels like having a significant dose of protein with every meal, sooner or later I will get this question: “But isn’t eating so much protein bad?” I’m not sure where this fear stems from, but I blame the crappy fitness and health industry. No, it isn’t bad for you, quite the opposite is the case, it is healthy! Let me explain why. Continue reading “Protein: Myths and Reality”

Protein: Surf’n’Turf Anyone?

Everyone needs protein. Period. It is not just the big muscular gym guy, also you sitting in the chair diligently doing your job or you running a half-marathon or you playing football. Why? Because proteins are the brickstones of our body, they are the catalysators (= enzymes) of our metabolism and are also fuel. To say it in numbers: after water (70%), proteins (18%) are the second main component of human cells. That’s why it may be worth considering adding more protein to your daily food, especially if you are getting serious about living a more active and healthy lifestyle.

Why you get fat

Metabolism in a nutshell

As I already told you in my last post about macros, no matter if you are eating low carb, low fat or low-whatever, if you are in a calory surplus the body start to store fat. Why? Let’s have a closer look at the picture below and follow the way of the macros:

Notes_180517_173057_37b_0.jpg

  • Carbs:Β in a very simplified way, carbs are broken down into pyruvate in a process called glycolysis. Pyruvate‘s fate depends on the body’s needs, it is either:
    • turned into energy and CO2 or
    • converted into fats through acetyl-CoA or
    • converted into aminoacids through oxalacetate or
    • turned into glucose again through oxalacetate in case of low body sugar.
  • Fats: to keep it simple, dietary fats are broken down into acetyl-CoA, which can be either oxidized into energy and CO2 or used for synthetis of (other) fats.
  • Aminoacids:Β simplified aminoacids can go two ways:
    • either through pyruvate into acetyl-CoA (energy and fat synthesis) or
    • some of the aminoacids can be used for glucose synthesis through oxalacetate.

Acetyl-CoA is the reason why everything you eat can be converted into fat and stored in the adipocytes (=fat cells). Therefore, the key for fat loss is not omitting one of the macros from your diet, but to be in an energy deficit (=eat less calories than you need). Nevertheless, it can be crucial to eat enough protein and useful to have more or less carbs and more or less fats in your diet depending on your needs (it is NOT the same for everyone!).

I will cover every macro in my future posts. Hope you enjoyed my small biochemistry lesson. See you soon!

Success! You're on the list.
