i lost 4lbs and i don't know how?

Hello, im a 20 y/o female 120lbs 5"5. i have always been naturally thin, sometimes too thin looking but never underweight ( I had no muscle). So i started off at 118lbs 3 weeks ago, and after a week and a half of working out i gained 5 lbs., it was all muscle not fat (im guessing because muscle weights more and how could i have gotten fatter after workingout?). So now 3 weeks into my workouts I lost 4lbs? I have gained a lot of muscle the past 3 weeks, my legs are pretty much all muscle, my tummy has very little fat, my arms im sure have some, but im pretty much toned all over now. So why did I loose the weight after i just gained it? i thought muscle weighted more? So that would mean i should be gaining weight, not losing it? i don't really care about my weight, i only care about being fit and healthy, i was just curious as to why i lost 4 lbs.? I am eating enough calories, protein etc. so why? to be more specific, i do strength training and cardio 5-6 days a week for an hour. i am a lot more toned now then i was before but i lost weight, am i missing something?. Please no rude answers, i am new to this

    I think it's more likely that you gained 4 pounds of excess water when you started working out and lost them as your body got used to the routine. Our bodies naturally flood sore muscles with water to help cushion and repair them when we start a new workout routine. This gives your muscles a "pumped" look and you'll see an increase in scale weight, but it's temporary.

    Adding muscle increases your metabolic rate, which means you burn more calories just sitting down than you did 3 weeks ago. To lose weight you must have a calorie deficit (after taking into account food intake and energy burned while exercising and just doing stuff during the day), so you're obviously eating less than your body requires to maintain current weight. So, the weight you've lost could be body fat, a bit of muscle, or even some visceral fat (fat build up around internal organs - ie. fat you can't see).

    I wouldn't worry about the scales as long as you are happy with the results you are getting, how you look, and how your clothes fit. Body composition is far more important than the numbers on the scales.

    Keep up the great work!

    More than likely the 5 lbs you gained was water and glycogen for muscle repair and 4 lbs of the water was released. Gaining muscle doesn't happen in such a short period of time.

    It's water. Muscle gain doesn't happen that fast...even for a guy with good genetics, 5 Lbs of actual muscle would take months of hitting the weight room hard and a spot on diet.
