The ketogenic diet has been referred to as the biggest diet sensation – ever – in the nutrition industry. So it’s worth looking into for that reason alone.

A ketogenic diet is very One Shot Keto – Modern Diet Secret of Thousands of people saturated in fat (about 75%), moderate in protein (about 20%), and incredibly low in carbohydrates (about 5%). It’s intended to put the body into a state of ketosis. In ketosis, your body breaks down fat to generate ketones for energy, rather than burning glucose.

Benefits of Keto?

Ketosis benefits we typically hear about are weight loss, increased HDL (“good”) cholesterol, and improvement in type 2 diabetes, along with decreased epileptic seizure activity and inhibition of cancerous tumor growth.

Small studies show promise for women with PCOS (polycystic ovary syndrome), an insulin-related condition. This may be because of its possible (not conclusive) ability to reset insulin sensitivity.

Everything Old Is New Again?

The current Keto diet isn’t the first time we’ve targeted carbs as a dietary villain. Medical trials with low-carb eating and/or fasting go back to the 1850s and even earlier.

In 1967, Stillman introduced The Doctor’s Quick Weight Loss Diet, featuring essentially nothing but low-fat protein and water.

Next came the Atkins diet in 1972, saturated in fat and protein, lower in carbs. It helped with weight reduction and also with diabetes, hypertension and other metabolic conditions. It’s still popular today.

In 1996, Eades and Eades introduced Protein Power, a very low-carb diet that appeared to help patients with obesity, hypertension, high cholesterol, and/or diabetes.

So reducing carbs, as the Keto diet does, has a history of helping people lose weight and/or improve metabolic factors. Anecdotal evidence supports that.

Does Keto Have Any Other Benefits?

Probable benefits could be seen with neurodegenerative conditions, such as for example multiple sclerosis, Alzheimer’s or Parkinson’s, likely because these brain disorders are related to metabolic disorders. In fact, Alzheimer’s is currently called Type 3 diabetes.

Care for these conditions is most beneficial done under medical supervision.

Ketones also may actually improve traumatic brain injury, based on research done on rats.

In the Interest of Full Disclosure…

Initial weight loss with the Keto diet is rapid. Your body has used its stored glycogen (carb stored in muscle) and dumped the water that’s stored with it. After that, weight reduction may continue, but at a slower rate.

Metabolism shows a short increase that appears to disappear within 4 weeks.

Keto doesn’t may actually offer long-term advantages in either weight loss or lean mass gains.

In some people, Keto seems to increase LDL (“bad”) cholesterol.

What About Negative Effects?

The usually mentioned “cons” of a ketogenic diet are nutrient deficiencies because of missing food groups and a distressing transitional state called “Keto flu,” which might last for days. It comprises hunger, dehydration, headaches, nausea, fatigue, irritability, constipation, brain fog, sluggishness, poor focus, and insufficient motivation. Because these symptoms are so similar to those of individuals quitting caffeine, Keto has been posited as a “detox” plan.

Other negatives include issues with gut health on this type of low-fiber diet and problems with adherence.

Regarding workouts, the Keto diet probably offers no advantage for many people. In fact, the glycogen depletion it induces may lead to hitting the wall (bonking). Athletic performance involving speed and power could be lower without glucose and carbohydrates as fuel.

The International Olympic Committee has urged athletes in order to avoid low-carb diets. They may lead to poor training adaptations and decreases in both power output and endurance. A colleague of mine induced cardiac arrhythmias in rats exercising on a low-carb diet.
