The concerns with Ketogenic Diet are many. The first and foremost one is sustainability. Almost all diets fail because it\u2019s difficult to sustain the diet and benefits. Keto diet is difficult to follow in long run especially the high fat content which is not palatable. Because of the very low carbohydrate intake there\u2019s major restriction in eating vegetables and fruits and other plant based products. This causes micronutrient deficiencies especially vitamins. It also means low fiber content and constipation.\u00a0 The high fat content is associated with increase in LDL cholesterol level in blood which has been shown earlier to be bad for the heart. Physiologically when we get calories from ketones there can be acidosis. It can lead to kidney stones<\/a>.\u00a0 During the initial phase of Ketogenic Diet when the body is not used to ketosis there can be flu like illness with dizziness, vomiting, headache and fatigue.<\/p>\n There is no long term data on the effectiveness and safety of keto diet. Evidence for effectiveness of weight loss induced by keto diets in reducing cardiovascular disease<\/a> and mortality is also not available, whereas there are other diets like Mediterranean which have clinical evidence for reducing heart disease.<\/p>\n To summarise Ketogenic Diet is effective in reducing weight numerically more than low fat diet.\u00a0 But whether this can be sustained is not known. It is not physiological and hence the long term consequences have to be studied in large population before clinical recommendation can be made. But it is becoming clearer that too much of carbohydrates especially the refined type is not good for health<\/a>. Hence what can be recommended is definitely lower calorie intake to lose weight with reduction in refined carbohydrates. Moderation in consumption of fat is essential but we still have not heard the last word. All fats are not the same and may not necessarily be as evil as portrayed.<\/p>\n![\"Dr.](\"https:\/\/www.kauveryhospital.com\/blog\/wp-content\/uploads\/2020\/11\/Dr.-K.ABIRAMI-Nephro2019-03-06-03_46_33pm-e1604397440600.jpg\")
