Likewise, phentermine has also been proven as an effective drug for short-term weight loss goals. It works wonders if used alongside a calorie-restricted diet and physical activity.

In this article, we will discuss how phentermine works with intermittent fasting, what are the benefits and potential side effects of their use together.

What is Phentermine and How Does it Work?

Phentermine is a prescription medication used for weight loss. It is an appetite suppressant that works by stimulating the central nervous system and making you less hungry. It is usually prescribed by a doctor for short-term use only as it is a habit-forming drug. It is generally prescribed to those people who continue to gain weight even after dieting and exercise. However, phentermine also works only if combined with a healthy diet and exercise.

Phentermine is called a controlled substance because it comes with dependence. Thus, before using this medication, medical advice is required. It is usually given to people having BMI greater than 30.

Since phentermine is an appetite suppressant, it suppresses your appetite and limits your calorie consumption. Staying in a calorie deficit for a long time can result in weight loss.  It acts as a central nervous system stimulant and also enhances energy levels and augments alertness. This medication acts by increasing the neurotransmitters such as norepinephrine, serotonin, and dopamine levels in your brain which eventually leads to reduced hunger.

What is Intermittent Fasting and How Does it Work?

Intermittent fasting is an arrangement of eating that cycles between periods of eating and fasting. It is an eating pattern that restricts you from consuming any calories up to an extended period which can stretch from 16 to 24 hours. However, to keep yourself hydrated throughout the fasting window you can consume as much water, and calorie-free beverages such as black coffee or tea.

This fasting arrangement does not focus on what to eat rather it emphasizes when to eat. It allows you to eat your meal within a specified time in a day. For example in a 16/8 plan, you have to fast for 16 hours continuously and then eat in the next 8-hour window. However, during the eating window, you must eat the required amount of calories to benefit yourself.

Intermittent fasting works by reducing the insulin levels in your body, which starts to deplete the glycogen reserve to use as energy. When it runs out of glycogen reserve, it starts to use the body’s fats for energy, which eventually leads to weight loss.
