There is not need to feed a medium rat to a male especially one so small, even large males do not need anything larger than a small rat 55/75 once a week.
By feeding large prey you will end up with an animal that will not feed with consistency and that is overfed.
As far as weight do not focus on weight focus on overall proportion, I can't comment on the weight loss since aside from no it's not normal however I have seen people more often than not, not weight their snake properly or having faulty scales.
If the snake is eating but not growing have a fecal done.
