is this insane or what?

edinat

This is not my first time starting to loose weight, last year i had lost about 30lbs...but i think my body is insane, as soon as i start eating healthier foods, and exercising even 30 minutes, my body starts dropping those pounds like crazy. I have started my journey slowly fort he past 20 days, few exercises here and there(haven't watched food, just wanted to kick start) ..so on Friday i started changing my food habits, between Friday and today according to my scale on Friday morning i weighed 254 -this morning 247.....i mean is that insane or what 7lb difference? i know all the water weight and everything goes, but gosh 7lbs?
Not that i am complaining, but is that healthy???? or is m body just needing this right eating to be normal...idk confusedddddd!!! HELP!
