“So Keto is really just another diet that restricts calories, but places incredible strain on your kidneys due to the higher percentage of fat.”
Still waiting for that link...
I need to provide a link to show you that if you eat a high-fat, low-calorie diet, your body will produce ketone bodies as it burns fat and that this can trigger metabolic acidosis? If you'd ever studied biochemistry, specifically the Krebs Cycle, you would know this to be a fact.
The ketogenic diet first became popular 100 years ago and was used mostly to treat patients with childhood epilepsy. They found that it reduced the number of seizures experienced in some patients. This diet was high in fat and low in carbohydrates and protein, and one of the potential side effects was metabolic acidosis. This has been a possible adverse effect of the ketogenic diet for a century. People who promote the diet to others should be aware of this.
