Take ST as an investment for your future. It will help you to keep the fat lost off. Most people struggle with keeping the fat off, not nearly as many people struggle to lose the fat.
Weight gain is normal when one starts a new exercise program. This is your body responding to a challenge, by holding onto the water, which it would have let go of if there were no new stimulus. This weight increase has nothing to do with fat gain.
Part of the problem is using weight as a measure of progress. It is a very poor indicator of success in fat loss. Even BMI is not entirely correct. What is very correct in assessing the fat loss success is body fat %.
I would get my body fat % measured every month (not more frequently, because it does not change faster even under ideal conditions), by skinfold calipers at least, at some gym that carries that kind of service. If you can't, get your body part measurements: chest, belly, hips and thighs every month. Monitor those measurements. You will save yourself a lot of frustration and your progress will be measured much more accurately.
