TABLE 1.

Types of diet to reach nutritional ketosis.

Diet	Specifics	Advantages	Disadvantages
Classic KD, VLCKD	4:1 ratio fat to protein plus carbohydrate	Faster in ketosis, more effective?	Less palatable, difficult to adhere
MAD	Carbohydrate intake restricted to 10–20 g/day (ratio 1:1 to 1.5:1)	More palatable, better adherence	Less effective compared to classic KD?
MCT	Medium chain triglycerides as fat source	MCT are more ketogenic	Not all fat sources can be used.
LGI	Carbohydrates with low glycemic index (<50).	More carbohydrates are allowed	Less production of ketone bodies, less effective?
KB supplementation	Oral ingestion of KB	Better adherence	Only direct effects of KB, no metabolic shift.
