My weight 45 kg. My height 157 cm.
I gain 5 kg I was 40 and my sister wedding is after 20 days I want to lose this 5 kg in 20 pleaseeee help!! I will do everything even if I will gain it after one month because I have to wear this dress!

Sorry.. you should have thought about losing the weight sooner than now (or more like watching your weight if you already had the dress)... you can't lose it fast... you might be able to lose some of it, that's less than 3 weeks... if you do it too quick you will put 20kg back on...

I would use phentarmine. Go to a doctor and have it prescribed to u.
