A low-carb, high-fat "keto-like" diet may be linked to higher levels of "bad" cholesterol and double the risk of cardiovascular events such as blocked arteries, heart attacks and strokes, according to new research.

 

Most health experts say the trendy keto diet, which bans carbohydrates to make your body burn fat for fuel, cuts out healthy food such as fruit, beans and legumes, and whole grains. In the keto diet, you limit your intake of carbohydrates to only 20 to 50 a day – the lower, the better. To put that into perspective, a medium banana or apple is around 27 carbohydrates – the full day’s allowance.

 

Keto is short for ketosis, a metabolic state that occurs when your liver begins to use stored fat to produce ketones for energy. The liver is programmed to do that when your body loses access to its preferred fuel – carbohydrates – and thinks it’s starving.
