Due to its effectiveness for weight loss, ketogenic, or simply keto diet, has become popular; however, health specialists warned that this diet may cause pre-existing ailments to get worse. 

According to the Philippine Association for the Study of Overweight and Obesity (PASOO), actual human researches do not suggest keto diet to those with diabetes, pre-existing heart conditions and at high risk of having a weakened heart.

On the other hand, overweight and obese individuals without any pre-existing conditions may go on a keto diet just to kickstart their desire to lose weight, although they should not practice this for more than 12 weeks, PASOO vice president Dr. Nemencio Nicodemus advised. 

“The scientific evidence only has until 12 weeks of evidence. Beyond that, studies do not show any benefit in terms of sustained weight loss,” he said.

Besides PASOO, Nicodemus mentioned that the Philippine Heart Association (PHA) as well as the Philippine Society of Endocrinology Diabetes and Metabolism (PSEDM) do not strongly recommended keto diet

Keto is a low-carb, high-fat diet which became widely known for a lot of weight loss testimonies across social media, claiming it helped them reduce weight faster.This diet allows your body to go on ketosis, wherein the body burns fat as a substitute for carbohydrates, which is the source of energy. 

In addition, Harvard Medical School cautioned that it does not only increase bad cholesterol or LDL, but also raises the risk of suffering nutrient deficiency, liver and kidney issues. 

Thus, it is necessary to consult doctors first prior going into any fad diets or workouts  one has read on the Internet, Nicodemus said.

“If you see a physician, you will be tested and asked your physical and medical history. That’s the only time they’d find out if you have a preexisting condition,” he added.
