When I started losing weight again at 193 last year, I got down to about 175 before people noticed - and omg it was like a flood gate of compliments and comments.

No one seemed to notice until I lost 40-50 pounds and some people still take a moment to say anything although that could just be them being polite. Seriously though the first 20-30 pounds people would look at me like I was lying when I said I had lost a lot of weight. :/

For me it didn't take that long at all. I think it's because the first place to "lose weight" is my face.

I started getting A BUNCH of comments after 60 pounds.

After about 10-12 pounds people noticed something was different, but after about 15-20 people definitely mentioned weight loss.

Mine was at around 45 lbs. They stated that they knew/noticed earlier but just werent sure if they should say anything.

25 lbs

But with a caveat.... people would say that they noticed I lost weight when I had gained it or my weight stayed the same... so I think sometimes people notice something is different, haircut or outfit or something and think it's weight loss, at least in my case!!!!

But when people could really tell it was about 25 lbs.

I'm down 32 lbs since this summer and haven't gotten much of any comments yet. I think part of the problem is that the vast majority of my weight was baby weight and DD is 2 so maybe they figure I finally pulled it together to lose the weight even if it's a bit delayed so it doesn't warrant commenting? Either that or some, if they haven't seen me for awhile, might have my prebaby weight me in mind when they see me (in that case I look 18 lbs heavier if anything).

I have a feeling I'll have to get well below my prepregnancy weight before i get any comments.

I've lost 30+ lbs in 2 months, and no one has noticed. I'm not really surprised by that though, as a) I don't think I look any different when dressed, b) I'm still wearing all the same clothes (my pants are too big now, but I'm hoping to get another month out of them and then go shopping for warm weather stuff) and c) most of my loss so far seems to have come from my waist and hips, and those are well-covered by my clothing. My husband says he can tell, but I think he's just trying to make me feel good (which is very sweet).

I'm hoping that when I get down to 20% of my body weight lost, which will be ~55 lbs lost, the difference will be more noticeable to people. Certainly by then I'll have had to purchase some new pants at least.

About 20 pounds or so for me (I had to lose 30 pounds in order to go down a size). There are so many factors, though. As was stated earlier, your starting weight and height are big factors. A 20 pound loss is less noticeable on a bigger person.

It was about 20lbs before anyone commented on my weight loss. So 215 down to 195-ish.

However, I put on 7lbs while traveling, and people are commenting that I look thinner. :/

I had started receiving comments about 15 pounds down and then they trickled away for a little bit. It was only when I reached almost 30 pounds down and bought clothes that actually fit me did people REALLY notice. But that's me. I agree with the others when they say it depends on how much you have to lose.

I started having people ask me if I was losing weight around 30 lbs. That prompted me to buy some new clothes, and right after that,everyone seemed to be noticing.

It was about at 50 lbs lost that people really started noticing(or making comments, at least) because that was also when I started getting new clothes.

I just had someone notice my weight loss last seek. I have lost 35+ pounds so far.
I've been throwing out my really baggy clothes, and I am wearing the next size down.
