SUMMARY: Without a doubt the combination of Phentermine and Topamax is one of the most popular stacks for fat loss. But are the risks really worth the reward or is there a better way?

Fastin is a sympathomimetic amine with actions similar to amphetamines.

Fastin may also enhance serotonin levels in the brain, which would also help suppress the appetite due to an elevation in mood.

How to Lose Weight with Phentermine and Topamax
The effectiveness of even the best belly fat burner depends on your willingness to control yourself and the amount of discipline that you install in yourself to lose weight.
The combination of Phentermine and Topamax, or even any of the best fat burner pills alone cannot lead to successful weight loss results without any effort on your part.
This is why it has to be used with each of the following:
1. A Good Diet
A good diet is the first step in effectively losing weight with your prescription. If you are not following any specific diet program, just follow some simple guidelines that have proven effective.
Start out by lowering your calories by approximately 250 to 500 per day and choose meals that are comprised of foods which are good sources of protein, low in starches and high in fibrous carbohydrates.
High consumption of vegetables will give you the benefit if getting all of the nutrients that your body needs to sustain good health.
You must avoid junk food that is high in sugars and hydrogenated fats which will only provide empty calories and lead to weight gain.
So if your goal is to lose weight with a prescription diet pill then you need to start by cleaning up your diet a little bit and start paying close attention to what you eat.
2. Self Discipline
Discipline is the second key to getting the most out of your fat burning pills. Having a realistic weight loss goal that you set for yourself will make you more likely stick to it.
If set a weight loss goal that is way too fat out of your reach, then you will be more likely to give up and never make any progress at all. So make sure that you use your discretion and set the bar high enough, but not too high.
After setting your goal, you must then stick to this goal by disciplining yourself to follow through. Take responsibility for achieving your goals since your success or failure is totally up to you.
3. Physical Fitness
The third key is to exercise, as it is not enough to just be able to control your dietary habits. You must make your body work in order to increase your metabolic rate and get the most out of your prescription.
By consistently engaging in an exercise program every week, you will literally jump start the effects of the diet pills in your system, which will give you many additional metabolic benefits as well.
You may also find that you are now stronger than usual because of the pills that you are taking. You may also find a noticeable improvement in your mood as you secrete serotonin as you sweat from working out.
Conclusion: Is This Stack Right for You?
Although taking a combination of Phentermine and Topamax such as Qsymia comes along with the risk of side effects, it is an effective means in which you can start burning fat faster than you are now.
Just make sure that you discuss your interest with your doctor or healthcare provider before making the decision to move forward.
If you are wary about the side effects and dangers then you can opt for one of the stronger legal alternatives such as Phentramin-D.
Although not as powerful as a prescription weight loss drug, Phentramin-D is one of the best diet pills available that you can buy without a script.
