Super hot this year, the ketogenic diet consists of 75 percent fats, 20 percent protein, and only 5 percent carbohydrates.

The metabolic goal is to utilise the fats as energy (and ketones, one of their biochemical byproducts) instead of glycogen (stored glucose, or blood sugar).

After about four days of inadequate carbohydrate for fuel, the body shifts to a state of "ketosis" (burning fat instead of stored glucose) which can be verified through a simple blood or urine test.

Weight loss will occur on a ketogenic diet, but it's not sustainable. According to Petra Colindres, MA, RDN, multiple nutrient deficiencies (notably fiber, vitamins, and minerals) exist on the keto diet, and the scientific research just isn't there yet.

Ketogenic diets have shown promise for paediatric epilepsy and is being studied in conjunction with other diagnoses as well.

But, for long-term weight management, Colindres states keto can't even be tweaked to be healthier.
