text: i've been eating alot, but i'm loosing alot of weight? what can this mean? i've dropped almost 30 lbs in a month, even though i'm eating alot and eating healthy the whole time, 3 meals a day, snacks, midnight snak the whole shebang if you have been doing any sort of regular exercise, this can be expected.  depending on your age, it's most likely just your metabolism.  it tends to speed up when we're younger.  at the risk of sounding rude, enjoy it while it lasts as it does tend to slow down over time.
