Carbs are our main source of energy. That's why 100% of the carbs we eat is quickly converted to glucose. The Keto diet is not a new fad; it's a very old one. You may remember the "Stillman" diet many years ago. Same basic idea - eat mostly meat, eggs, cheese & severely limit plant-based foods, which is where the carbs are. Your body will then be forced to use stored fat for energy....sort of "Temporary Diabetes." That's why one of the first signs of diabetes is unexplained weight loss. Instead of using sugar for energy--which your body is designed to do, it uses fat--which is not designed to be used for energy.
Metabolizing fat for energy produces Ketones in the blood & urine - that's where the term "Keto" comes from, & that's why they sell those strips you can test your urine for, to see if you're in "Keto Mode." As others have said, that can cause other problems - which is why the Keto diet may not be safe for the long haul. One possible risk is osteoporosis. Unlike a carnivore's system, which is acid, our system is alkaline. Excess protein creates an acidic balance & our system uses calcium from bones to neutralize the acid. That can lead to brittle bones. It's not how much calcium we eat; it's how much we keep.
I don't blame anyone for wanting to lose weight - any way that works, regardless of the risks....I've been there. But it's not necessary to risk your health to lose weight.
I had a weight problem since birth - a chubby child, an obese adult & by age 28, 405 lbs & all the misery that goes with it. In my photo from 2015, I'm 185 lbs. I've now been at 170 lbs for the past 6 years. I didn't restrict fruit or vegetables, in fact I increased their consumption. I did severely restrict processed carbs - the carbs found in soda, pasta, bread, cookies, chips....everything we like to eat.
