If you’re on this diet avoid cheat days

Research presented by Jonathan Little, from the University Of British Columbia Okanagan Campus and colleagues portends about allowing moderate indulgences while adhering to a low carb, high fat diet. An examination of a group of healthy young males intimates that those that subscribe to the Keto diet can potentially damage blood cells by permitting cheat days.

“Since impaired glucose tolerance and spikes in blood sugar levels are known to be associated with an increased risk in cardiovascular disease, it made sense to look at what was happening in the blood vessels after a sugar hit,” explains the study’s first author, Cody Durrer.

The Keto diet has become particularly popular amongst Type 2 Diabetes patients wishing to mitigate blood control in the short term. The diet causes the body to enter a state called ketosis, through the consumption of foods rich in fat but moderate in protein and very low in carbs.

“We were interested in finding out what happens to the body’s physiology once a dose of glucose is reintroduced,” says Durrer.

No cheat days

Participants involved in the study were put on a diet similar to the modern ketogenic for seven days. At the start of the week these individuals were tasked with consuming a 75 -gram glucose dose (the amount comparable to a serving of fries or one large soda.)

At the conclusion of the experiment, the researchers examined the blood vessels of the participants and found the otherwise healthy young men expressed readings of a person of poor cardiovascular health. Little, the study’s senior author, described the find as “alarming.”

Many votaries of the Keto diet adopt it with the intention to either prevent or help repudiate adverse heart effects informed by being overweight. Little worries though that individuals that already have a predisposition to cardiovascular disease might be undoing the positive impact on their blood vessels by allowing a cheat day or two on the famous diet. He adds, “Our data suggests a ketogenic diet is not something you do for six days a week and take Saturday off.”
