We’ve
all been there. This popular fad diet has made its way into our fitness goals
at some point or another. And if you haven’t tried it yet, don’t!
Let’s
talk about the basics of the keto diet.
The
rules:
You
cut down your carbohydrate intake to 50-100 grams/day by excluding refined
sugar, pastas, rice and surgery fruits and vegetables from your diet. Instead,
you fill up your plate with fat and proteins.
The mechanism:
Your
liver stores some 50 grams of carbohydrates in the form of glycogen and your
muscles holds onto some more. When you exclude carbohydrates from your diet,
your body is forced to first utilize the glycogen stored in your liver and then
muscles to obtain glucose aka energy.
Once
you’ve depleted your glycogen stores, your body will start using the stored
fats to get energy by way of gluconeogenesis. This way, you will slowly begin
sloughing off that fat!
But
there’s a catch. Our brain, the most vital organ of our body, relies solely on
glucose for energy. And it needs it fast!
Getting
glucose from carbohydrates is a relatively fast process, whereas getting it
from fats takes time. Thereby, you end up depriving your brain of its energy
source!
Moreover,
when you replace carbohydrates for fats, you take in increasingly greater
quantities of triglycerides. This can raise your body cholesterol levels, and
increase your risk for developing cardiovascular diseases.
