If you're not really overweight by much then losing 10 lbs of weight is likely not very noticeable to most people.
I didn't really notice my weight loss until I lost at least 20 lbs and then after I lost 40 lbs I really noticed the difference.
My mom said she noticed a little bit of difference in my waist size after I dropped 10 lbs but I really didn't notice and at the time my pants did become a little bit loser but not much.
I really noticed my pants size drop after I lost 20 lbs to 40 lbs.
But you might notice a bit of a difference yourself at 10 lbs especially if you were or are really overweight to begin with.
Still losing 10 lbs of weight is good and means you're doing what you're supposed to so that you lose the weight.
Just continue to exercise, eat healthy etc and you'll continue to lose weight.
