Weight Reduce is not easy cakewalk. It needs a lot of dedication and consistency.
I reduced 4 kgs in 6 months but when I became irregular with my program, I gained it within a month :(.
Weight can be easily reduced by doing cardio. Just burn daily 1000 calories and do some weights, the extra weight will start going and daily the effect can be figure out.
But once you feel that you have reduced enough and start being rlax the extra weight reduced will come back very fast.
It easy to reduce weight, but its very tough to sustain that reduction that I learned.
