Any diet in which there is a calorie deficit is catabolic in nature. Ketogenic diets are not good for mass gains because inulin, an anabolic hormone, is very low.
Generally, a good rule of dieting is to never mix carbs and fats together (which is pretty much the standard american diet ). Eat protien (1-1.5g per pound of body weight) with some carbs (piece of fruit or oatmeal or vegtables etc...) or with fats (olive oil or flax or a little peanut butter etc...) and you should never have a problem with weight.
