Primarily, the "ephedra" based diet pills are amphetamines, causing your heart rate to increase and more blood to flow. Thus it fools your heart into thinking your exercising 24/7. I guess that may cause your appetite to decrease, while increasing your metabolic rate. Most of them have caffenine in them also, which studies have shown caffenine is an appetite suppresant and keeps you alert. I am just basing that on the ones I have taken before, (Stackers, yellow jackets, midnight stallion). My heart rate increased dramatically, very jittery, and my body temperature increased.
That's just my take on them. I do not think they would make a person lose weight significantly, they could possible just jumpstart your system. Def. decrease your calorie intake and increase your exercise is the best way to go for weight loss. A pill will never solve a problem in this case.
Every person is different, every person reacts differently to the pills, I've tried every diet pill imaginable in the history of mankind, they start off okay for the first two weeks then the pills start slacking off after that or I do LOL, anyway if you have some will power they might work for you but if you dont' than forget it, don't waste your money, I could be rich with what I've spent over the years and I've been overweight most of my life, the only pills that ever worked were the phen-phen and they took those off the market. So I hoped I help in some way. dee
I lost 50 pounds in 3 months with phentermine, it was great, controled my appitite and gave me energy, had to adjust the dose after the first month and go up. Oh and BTW there is NO Ephedra in phentermine. Ephedra or epherdrien is for asthmatics. It is Bronchial dilator that speeds the heart and raises metabolism. Fastin is a great drug but it will not do it alone, it only assist in weight loss, you still have to do the work by diet and exercise.
Ephendrine... definitely works. I get the pure stuff from the health food store down the road that is not mixed with anything. Its original purpose is a decongestant (which is also great for my allergies), but it also takes away your appetite and increases your metabolism. When you exercise on it you will run further and lift more weight also. Of course, like any medication there is side effects and precautions to take. Please read up on it first.
I get mine from the health food store at $9.98 for 50 pills. I usually take the reccomended 4 pills maximum daily. I feel 10 times more inclined to exercise and will actually push myself and feel motivated. My fitness guro friend takes it before he works out. He has to eat before he takes the pill because the appetite suppressant is too much and he will not be hungry for the rest of the day. You do not feel nauseated on the pill, just not hungry. No interest in the food.
