Extra Burn Keto – On the other hand, another calorically matched study found a reduction. The ketogenic diet group didn't see much of a difference but the low-fat control group saw a notable reduction. Flow-mediated dilation is sometimes worsened on a ketogenic diet and improved on a low-fat diet, although this isn't always the case in studies.
Other studies find that keto diets reduce daytime sleepiness or increase time spent in REM sleep; some, however, focused specifically on children with epilepsy and may not be generalizable to other populations. The diet gets its name from ketone bodies, which are metabolites of fat produced in the liver as it breaks down stored body fat for fuel use by the rest of the body. A distinguishing feature of ketone utilization is that insulin is not required to escort ketones into cells, as it is with glucose. Forcing the body to burn fat as fuel gives insulin time off. That restores the body’s sensitivity to insulin, resulting in lowered levels of both insulin and glucose in the blood.
