There is no established definition of what constitutes a low carbohydrate diet beyond the idea that they all have some type of restriction on carbohydrate intake. Therefore I will classify low carbohydrate diets as "Carbohydrate Optimization Diets", "Non-Ketogenic Low Carbohydrate Diets", "Ketogenic Diets", and "Extreme Calorie Restriction Diets", as well as the baseline "Standard American Diet". The specific diets can then be mapped into these categories. {{Skeleton}}

* '''[[Non-Ketogenic Low Carbohydrate Diets ]] (NKLCD)'''. A NKLC diet restricts overall carbohydrate level, typically to around 50-150g of net carbohydrate, but does not elevate ketone levels sufficiently to be considered a [[Ketogenic Diet]]. A diet that restricts net carbohydrate intake to below 50g may still be Non Ketogenic if protein intake is not also sufficiently restricted.* '''Ketogenic Low Carbohydrate Diets (KLCD)'''. A ketogenic diet [[Ketogenic Diet]] restricts both carbohydrate and protein intake so that the body metabolizes fat to produce ketones. There is no established definition of what level of ketones are required for a diet to be considered ketogenic. (Fasting ketone levels are typically ~0.3 on the SAD [Effects of a high<ref name="Johnstone-protein ketogenic diet on hunger, appetite, and weight loss in obese men feeding ad libitum]2008"/>.) Also, because it takes time to adjust to a ketogenic diet, I do not consider a diet to be a 'ketogenic diet' even if it elevates ketone levels for less than two weeks. A ketogenic diet should only be started under medical supervision. A Ketogenic diet is sometimes referred to as a Low Carbohydrate Ketogenic Diet or LCKD.

| [[Ketogenic Ratio Diet]]

* '''[[MCT Diet]].''' This is a variant of the traditional diet that uses Medium Chain Triglycerides ([[MCT]]s) that produces which produce more ketones than other oils. The MCD Diet is typically only used for the treatment of epilepsy.

* '''Low Glycemic Index Treatment (LGIT).''' The LGIT restricts the carbohydrate intake to only those foods with a [[Glycemic Index]] of less than 50<ref name="Kossoff-2011-3230"/>. However, the LGIT is more than just restricting the glycemic index, and requires a fat intake of 60% with a [[Ketogenic Ratio]] of 1:1. The LGIT is similar to the MAD and restricts carbohydrates to , but allows 40-60 grams/dayof carbohydrates. * '''[[Ketogenic Ratio Diet]]'''. The [[Ketogenic Ratio]] is commonly used to construct a diet to treat drug resistant epilepsy. The ketogenic diet measures the ratio of grams of fat to the grams of protein plus net carbohydrates[[Net Carbohydrates]]. For example a 4:1 diet has 4 grams of fat to each gram of carbohydrate or protein. However, this ratio is slightly misleading, as there are other constraints on the diet. By tightly controlling the overall calorie calories and protein intake and <span style='color:#FF0000'>XXXXX</span>in addition to the ratio, carbohydrate intake is indirectly tightly controlled.
