Loose Weight in One month time

How bad am I to loose my weight?
Very desperate!
Anything that I have not done to loose weight?

I did :
- Yoga
- Pilattes
- Dancing
- Aerobic
- Gym exercise
- Starve myself
- Don't eat rice for 3 months
- Diet pills
- Detox

Many more to list down.

Result '0'! Why??
I believe I am not persistence enough.

I wish to loose weight at least 3kg during this fasting month.
Last year I loose 4 kg during fasting month but gain another 5kg right after normal month. ahahaha... yeah!

Tell me about it! I bet many of you face the same problem as well right???
