The empowering hashtag has been used over 25,000 times, with women posting before and after images contradicting the commonly held belief that less kilograms equals health and happiness.
Yep, these women appear more fit after gaining weight, and many share their experiences of not only transforming how they looked, but how they felt.
"To the left I was weighing 166 pounds (75kgs) and the other day I realised from going down to 140 (63kgs) i'm back up to 166, that this time it looks a little different," @letler writes. "While I lost those 30 pounds (on accident by the way) I always focused on performance goals. Whether I wanted to increase my cardiovascular or just increase my strength. Focusing on performance goals with proper nutrition of course, the weight melted off and got put back on in lean muscle without even focusing on the numbers!"
@deeper_than_muscles captioned her before and after image: "A lower weight does not equate to being healthier: I weighed 15lbs (9kgs) less in the first picture than I do now. This is for multiple reasons. I leaned out, losing fat but gaining muscle, and since muscle weighs more than fat-- the number on the scale increases. #bonusfact, the more muscle mass you have, the faster your metabolism works 24/7. So.... #screwthescale."
"Growing up I was ruled by the scales thinking weight was directly correlated to health," @healthybyfifty said. "I was so wrong."
@victoria.malmbbg writes: Screw the scale, seriously. I understand it's the only good way to measure in sports and when people are sick with life threatening diseases. But for a normal person living a normal life like myself, you don't need that kind of negativity. Because it will never make you feel good.
"If you'd told that girl on the left that she would gain 6 kgs she would have been devastated, @imrececen writes. "'6kgs?!? Won't that turn me into a fat monster?'" Yet here I am 6kgs heavier but also more confident than ever!"
