What is the best weightloss programs that actually work?

Fatness is causes varous sickness, so many people want to loose their weight.
There are many weight loose programs. The easiest and free of cost of weight loose program is drink lots of water not to eat sugar and fatty foods.

I know that jenny craig helps a lot of people. However I lost 21 pounds without any program. I just cut my calories down to 1300 a day. I made sure I kept a food diary as well to record everything that went into my mouth.

I don't think any programs will lose your weight.
