I read somewhere that it takes 4 weeks for you to notice a loss, 8 weeks for the people who are always around you and 12 weeks for the rest of the world...or something like that. They didn't say how much weight you needed to lose for this table but I usually don't hear anyone say anything until it has been at least a 20 pound loss. Most of the time it takes my clothes getting loose for me to realize I am really losing regardless of the numbers on the scale because when I look in the mirror it doesn't look much different to me.
I lost 40 lbs very slowly (1.5 years) so I don't really feel a difference but when I look back at old pictures I can definitely tell.
The people that see me all the time haven't really noticed, probably because it was so gradual.
I am almost down one pants size. Most of my weight is in my butt and thighs so it takes a long time to go down sizes for me.
Really depends on your body fat distribution. some people lose fat on their face first, while others lose fat on their legs, chest or belly. But dont worry if you are doing the right stuff you are losing weight!
