The ketogenic, or "keto", diet has gained significant popularity over the years. But what exactly is it?
The ketogenic diet is about managing your dietary macros. As such, it is a high-fat, moderate-protein, and very low-carbohydrate eating plan. When carbohydrate intake is minimized, the body enters a state called ketosis where it burns fat for energy.
The goal is to become "Keto-adapted". "Keto-adapted" refers to the physiological state in which the body becomes efficient at utilizing
ketones as its primary energy source. This adaptation happens after someone follows a ketogenic diet
for a sustained period.
A ketogenic diet shifts the body's primary fuel source from glucose (sugar) to ketones. Ketones are
molecules produced in the liver from fats when there's a limited intake of carbohydrates.
When someone first starts a ketogenic diet, there's often a transition period where the body adjusts
to burning ketones for energy instead of glucose.
This period can be marked by symptoms commonly
called the "keto flu," including headaches, fatigue, irritability, nausea, and muscle cramps.
After a few days to several weeks, as the body becomes more efficient at using ketones, many of
these symptoms subside, and the person might experience increased energy, improved mental clarity,
and other benefits.
At this point, the body is said to be "keto-adapted."
It's important to note that being in ketosis (having ketones present in the blood) and being
keto-adapted are related but distinct states. A person can enter ketosis within a few days of
starting a ketogenic diet, but becoming fully keto-adapted typically takes longer.
While the ketogenic diet offers potential health benefits, it's crucial to do your own research and consult with your physician or medical professionals before diving in. It's a significant change and might not be suitable for everyone.
