You're talking about managing weight, weight has nothing to do with anything. If a human eats too much to fast, they get fat, but will still grow at a normal speed, if a human eats less and healthier, they will be thinner and healthier, but still grow at a normal speed.

If you were to feed a human less than they should get as a growing child, then you will stunt their growth. If a person should be eating 3 meals a day, and you only fed them once a day, or every other day, I'm sure you could stunt their growth until they didn't reach their full potential.

The only way you can get your snake to not grow like it should normally, is to not feed it enough to maintain healthy growth, which is stunting it's growth, not managing. Managing would be making sure your snake doesn't get too fat, like feeding an adult ball python a large rat every single day. That could potentially make a fat snake. But a large rat every week to 10 days, would allow for a healthy weight and normal growth rate.

Like hatchling BP's/retics can be fed every 3 days without becoming fat and still grow at a normal pace. They can also be fed every 5 and 7 days while still growing at a normal pace and not becoming fat.
