Thus, a keto diet should be tried only when there are few other alternatives. Though keto diet is beneficial, it is an extreme diet and difficult to sustain it for long. It is advisable to follow a more balanced, practical diet planning, depending on the individuals, based on lifestyle, metabolic state, cultural background and individual preferences. A more sustainable, subtle energy deficit with some fresh fruit while avoiding high glycaemic index foods is a good way to achieve long term results. People with diabetes are keen to follow ketogenic diet, as it is an effective approach to reduce weight and control the blood sugar level.
