Monitors and snakes come from a common ancestor so as of right now until further DNA tests can be done on other lizards, monitors are the closest relative to snakes.
Seasonal fasting is in many reptiles, again something my boa demonstrates every year, for what ever reason. So when times are good (spring until fall) she will gorge her self just like monitors. Then she will fast, it is perfectly natural and until I can get proof about obesity and a BMI I will have to go on the evidence I have.
Obesity in savs is directly related to exercise and prey offered. Feeding savs rodents is like feeding yourself mcdonalds every day. This is another reason I am looking into more birds for my snakes. A strict mammal diet is not always natural and a variety is best. Again obesity is determined by exercise, amount of food and type of food and in my opinion limiting food should be the last way to fix this problem. A problem we can not fully understand with out a BMI.
