Fat burners are used to raise your body temperature and increase your metabolic rate which helps your body burn calories as heat efficiently during exercise. Due to this increase in your metabolism you end up with more energy and a release of adrenaline for a short period of time aiding you to exercise harder and stronger (and easier) and kick start your body to burning fat for a longer period of time, even for hours after you stop exercising.
Also known as thermogenics, a fat burners like Phen375 is a blend of stimulants and herbs. They used to contain Ephedrine, which is a synthetic version of the Chinese herb ephedra, but due to its’ harmful side effects and addictiveness you can only obtain these via prescription in the UK and should be avoided unless authorised by your doctor.
Most contain caffeine and stimulate the release of adrenaline and raise cortisol, a stress hormone, so if you suffer from anxiety or panic attacks it is not a good idea to take them and you should consult a doctor. Which you should do anyway if you are considering taking any sort of stimulant as some can raise blood pressure or cause heart disturbances.
When is the best time to take a fat burner?
As they are stimulants the best time to take them is in the morning letting your body burn calories throughout the day, plus if you take them after 2pm they will upset your sleeping pattern. They are similar to drinking countless cups of coffee, which will make you feel quite strange if you are not using them in conjunction with eating healthy foods and some form of exercise like lifting weights or jogging to release the increased levels of adrenaline and energy. It worth taking note of super foods as tese are easy to get into your diet.
Always follow the instructions on the bottle and be careful with long-term use. It is said to only take them on a 14 days on 14 days off for two cycles in every eight weeks. Once you are exercising regularly and in the correct manner you should not need to take a fat burner. Using HIIT (High Intensity Interval Training) at the beginning of the day can produce a similar effect without using drugs at all.
A simple example of HIIT is running as fast as you can for thirty seconds then dropping down to a slow jog for 30 seconds and then repeat for nine minutes, this confuses your body in to keeping your metabolism burning for hours after.
A healthy balanced diet is also highly recommended to aid your body to burn fat in an efficient healthy manner.
