When you’re aiming to lose weight, alcohol is often best avoided due to the number of calories it contains and the effects it has on the body, but for those taking phentermine there are further risks to consider. Here we explain how alcohol hinders your best weight loss efforts and why it is inadvisable to mix phentermine and alcohol, with respect to both the success of your weight loss journey and to your health. How Alcohol Effects Weight LossThe bottom line is, alcohol and weight loss really don’t mix. There are several ways in which alcohol negatively effects the chance of success on your weight loss journey. Firstly, alcohol contains many empty calories, meaning it is high in sugars which get converted to fat without providing the body with any nutrition. Secondly, alcohol decreases testosterone levels and causes fluid loss and tiredness, meaning exercise is more difficult and less effective. As a depressant it also suppresses the functions of the liver for as long as three days following the consumption of alcohol, meaning it limits your body’s ability to burn fat and build muscle by stopping the liver from processing food into energy. Lastly, alcohol leads to poor food choices as it activates hunger messages in the brain, leading to cravings for unhealthy foods high in saturated fat and salt.

The problem with combining alcohol and phentermine arises from the fact that phentermine is a stimulant while alcohol is a depressant. Phentermine works as a weight loss medication because it directly affects the central nervous system by suppressing the parts of the brain responsible for appetite control, while other functions are stimulated to enhance energy and tolerance to intensive exercise. By contrast, alcohol suppresses the main functions of the central nervous system. The mechanisms of phentermine and alcohol are different, so simultaneous consumption of these can result in a negative drug interaction.Warnings about drinking alcohol while taking phentermine explain that the combination can increase the risk of cardiovascular side effects, such as increased heart rate, chest pain or changes to blood pressure. You may also be more likely to experience symptoms such as dizziness, drowsiness, depression and difficulty concentrating. Some of the side effects that those taking phentermine have mentioned in the Phentermine.com support group on Facebook include: jittery feelings, an inability to concentrate or interact in conversations, feeling on edge, and enhanced anger.In addition to these negative side effects, alcohol also makes phentermine less effective, as one of the Facebook users mentioned in the link above. Alcohol activates hunger and greatly limits the effectiveness of the phentermine by reducing the appetite suppressing effects that phentermine has on the brain, while also decreasing the energy boost that phentermine supplies. Alcohol also effects the pH balance of the body, making it more acidic; phentermine has been shown to last longer in the body by as much as twice as long when the pH balance is more alkaline, which can be achieved by eating lots of fresh fruit and vegetables, while refraining from unhealthy acidifying foods and drinks like ice cream, butter, coffee and alcohol.Can I Drink Alcohol While Taking Phentermine?It’s best to refrain from drinking alcohol while taking phentermine, or at least to limit the amount of alcohol you consume. Your doctor will explain to you what you should and shouldn’t do while taking phentermine, including your recommended maximum intake of alcohol. To ensure that you are more aware of how alcohol affects your body when you begin taking phentermine, you should aim to drink slower and to alternate alcoholic drinks with glasses of water to keep yourself hydrated and to give the alcohol time to enter your body so you can monitor how you feel. If you begin to feel unwell or experience symptoms such as those mentioned above, you should stop drinking alcohol immediately.While it is true that some people experience no adverse side effects from mixing alcohol and phentermine, it is something that everyone should approach with caution, as when taking individual differences into account, this kind of drug interaction can be very dangerous for some people. Much of the success you will gain from your weight loss journey is related to knowing your body and acting in a way that you know is right for your health and well being. This means avoiding or at least limiting your alcohol intake so as not to experience these negative side effects when mixing alcohol with phentermine, as well as in order to enjoy a healthier lifestyle in the long term.
