Phentermine 375 Weight Loss Results – Scientific Study

Here are some results of clinical studies involving phentermine 375.

BMJ Phentermine Study

The British Medical Journal published the results of a 1968 trial that pitted three groups against each other. One group was given 15 mg per day, another had their dosage cut drastically every other month and finally there was an un impacted control for comparison purposes. All of the 36 women took part in this experiment with two separate variations within it.

The continuous dosing saw more weight loss at 27 lbs over time (a total expenditure limit) than those intermittent users who lost 28+lbs less despite having 1K fewer calories allowed on average daily diet plans.

Phentermine Clinical Study in Korea

A recent trial of phentermine’s weight loss effects was conducted in 2005 in Korea. This time, the standard dosage was 37.5 mg per day and tested on 34 people – both men and woman alike!

These subjects were asked to follow a 1500 calorie diet at 1mg/kg bodyweight each week for 14 weeks with no other change from their typical lifestyles aside from taking one pill per morning before breakfast (a total dose around 25 milligrams).

The results showed 16lbs lost by participants who took phentermine which works out about 5 lbs monthly – not bad considering most people only lose half an ounce (.04 kg) themselves after 3 months without treatment!?

Very Low Calorie Diet Study on Phentermine

In a 2003 study from UCLA, data on 188 male and female phentermine users was collected.

These dieters consumed only 500 to 800 calories per day with the help of medication that ranged in doses 8 mg – 30mgs for women or 300 milligrams up to 600 mg’s depending upon their weight loss needs.

The participants of the trail also received encouragement by meeting often at group meetings throughout each month as well as support via email where possible 

The average woman lost 17lbs over 12 weeks while males weighed 21+/-3 pounds monthly (6-7 lbs).

Phentermine 375 Weight Loss Summary

In the 3 sample studies shown above it seems that the greatest weight loss happens at the beginning, in the first few weeks, months.

After which the weight loss return become significantly lower. This is a general and common trend from virtually all weight loss diets and diet plans.

This research proves why the British Medical Journal study had such low rates of weight regain.

It wasn’t that people actually lost more slowly, but rather their rate slowed down significantly over three or four months after starting to use phentermine and then maintained it for up until nine more months afterwards. Unlike those on placebos who began at ten weeks out from surgery with no medication yet still gained back some amount if not all what was shed by time period ended.

Taking the data from the studies above you can expect to lose roughly 3 – 6 lbs. each month if you are female and 5-8 lbs if you are male using the combination of Phentermine plus an appropriately low calorie diet.
