Moreover, why do we need carbohydrates?
Carbohydrates are the body's main source of energy. In their absence, your body will use protein and fat for energy. When you're low on glucose, the body breaks down stored fat to convert it into energy. This process causes a build-up of ketones in the blood, resulting in ketosis.
Furthermore, when should I eat carbs? Consuming carbs at least 3–4 hours before a workout can help athletes exercise for prolonged periods, while consuming them within 30 minutes to 4 hours after a workout can help restore your glycogen stores ( 1 , 20 ).
Then, what happens if you eat no carbs?
When you don't eat carbs, your body — mostly your liver — can produce glucose out of protein and byproducts of fat metabolism. Therefore, because of ketosis and gluconeogenesis, you don't need dietary carbs — at least not for fueling your brain.
Why do people think carbs are bad?
“The main reason [carbs get a bad rap] is that when people think 'carbs' they think 'starch', like white rice, pasta, potatoes or white bread,” says Bowerman. That's why carbohydrate-containing foods like starchy vegetables, legumes and whole grains are included in many healthy diet plans.
