Imagine sipping a milkshake made with full cream milk and ice cream with a dollop of whipped cream on top…..heaven right?
Apart from creating a satisfying feeling, the milkshake with almost 70 to 90 grams of fat and 1000 calories also causes some changes in the body. A study (https://www.nature.com/articles/s41374-018-0038-3) was done on 10 healthy men drinking this milkshake. They were tested after 4 hours only to find that their blood vessels were not relaxing or dilating easily and the red blood cells had changed shape from being smooth to being spiky which could in turn affect the blood flow. The men also showed temporary elevation in the myeloperoxidase levels, an enzyme linked to stiff blood vessels and heart attacks.
High fat meals can cause acute lipemia and trigger myocardial infarction. The mechanism is poorly understood. This finding may be giving a direction towards unraveling the mystery. Regular high fat meals cause changes in the red blood cells which are closely associated with the inflammatory response in the blood vessels.
The takeaway is that as far as possible avoid high fatty intake. If it is once in a while it may not cause damage beyond repair but if you are regularly consuming such items , then remember that some permanent blood vessel and blood cell changes are happening without your knowledge.

Hi good question. The answer lies in what is inherent to keto diet, Zilch sugars and regular heavy workout to use the ketones generated for energy. The loaded milkshake featured here is also high in sugars. High sugars lead to a massive insulin spike. Lipolysis does not happen during a insulin high. The body cannot break down the fats and so it remains high in the blood for prolonged time. In keto diet, your body is taught to use the ketones for energy and regular workouts are recommended to use up the ketones. This is the difference, However keto diet has to be temporary for a short period inorder to teach your body to burn fats. It should never be a long term diet option!
