yes it does work and I hope there will be no bad side effects on you. As this will keep you perspire lots and makes your heartbeat go fast..
fad diets doesn't work along with other slimming products because as soon as you stop taking these, your weight will double what you've lost.
take it easy.. eat healthy natural foods (avoid anything processed) lessen the sugars or anything that contains sugars.. walk more and do more physical.. like walking, running, yoga, swimming and weight resistance as it is good for women to retain bone mass. Or get into a hobby like cycling, dancing, diving.

Hope your will meet your goal and keep it all the time.

Good luck.
