Is Phentermine a Good Way to Lose Weight?

Experts and medical professionals are welcoming the weight loss medication revolution that has come from the new game changing options available to tackle obesity and weight health related issues. 

That’s because the public has finally come to terms with the concept that diet and exercise alone is not the sole answer to breaking free from the cycle of chronic obesity. There are many reasons a person can struggle with sustainable weight loss, including but not limited to hormonal imbalances, medical conditions, ethnic background, and stress. 

Many of the new medical weight loss options are booming in popularity as accessibility has been in question, however for many people those injectable treatments may not be an option. Whether it’s ineligibility due to medical history, medication contraindications, or simply struggling with the idea of injections, some patients are missing out on the help of medical weight loss. 

However, Phentermine (also known as “the pink pill”) has been on the market for many years, helping hundreds of thousands of people all over the UK and US lose weight safely, sustainably, and efficiently. When Phentermine is combined with a fully supported nurse-led medical treatment programme – we see lives transformed, weight finally managed, and healthy, happier patients. That’s why, at Bodyline, we’ve been providing treatment programmes aided by Phentermine for almost 20 years, helping patients lose up to a stone in their first month on the programme.

What is Phentermine?

Phentermine is a prescription medication that belongs to a class of drugs known as appetite suppressants. It works by affecting certain neurotransmitters in the brain, primarily norepinephrine, serotonin, and dopamine, which help reduce hunger signals and control cravings. The medication has been used for decades as part of comprehensive weight management programmes for individuals struggling with obesity.

Phentermine comes in the form of an oral daily pink pill, taken in the mornings before breakfast and designed to last the whole day. The medication is recommended for short-term use in the management of obesity, prescribed for 3-months at a time, and regular breaks are required. 

How can Phentermine help with long-term weight loss?

Phentermine can be an effective tool for long-term weight loss when used as part of a structured weight management programme. By reducing appetite and food cravings, it creates an opportunity for patients to develop those sustainable healthier eating habits and establish a consistent calorie deficit. However, the key to sustainable results lies in using this medication as a stepping stone rather than a permanent solution.

The medication helps patients break through those initial barriers to weight loss by making it easier to adhere to a reduced-calorie diet. This period of controlled eating within a nurse-led treatment programme allows individuals to form new habits, understand proper portion sizes, and develop a healthier relationship with food and exercise.

Who is eligible for Phentermine?

Phentermine is typically prescribed to adults with a Body Mass Index (BMI) of 30 or higher, or those with a BMI of 27 or higher who have weight-related health conditions such as high blood pressure, type 2 diabetes, or high cholesterol. However, not everyone is suitable for this medication.

Candidates must undergo a thorough medical assessment to ensure they don’t have any contraindications such as heart disease, uncontrolled high blood pressure, glaucoma, or a history of drug abuse. Pregnant or nursing women are not eligible for Phentermine treatment.

How much weight can I lose with Phentermine?

Weight loss results with Phentermine can vary significantly between individuals, depending on factors such as starting weight, diet adherence, exercise routine, and overall commitment to the programme. When combined with proper diet and exercise, patients typically lose between 5-10% of their initial body weight over a 12-week period, and at Bodyline we’ve seen our patients lose up to a stone in their very first month!

It’s important to note that the rate of weight loss often slows down after the initial few weeks as the body adjusts to the medication. This is normal and emphasises why developing sustainable habits during treatment is crucial for long-term success.

Phentermine or weight loss injections?

The choice between Phentermine and weight loss injections like GLP-1 agonists depends on various factors, including individual health status, weight loss goals, lifestyle, and personal preferences. While Phentermine works primarily as an appetite suppressant, GLP-1 injections affect multiple body systems, including blood sugar regulation and digestive processes.

Phentermine might be more suitable for individuals who prefer oral medication and need short-term support to establish healthy habits. Weight loss injections, on the other hand, might be better for those requiring more comprehensive metabolic support and longer-term treatment options.

Why Bodyline’s support is vital for long-term success

“At Bodyline, we believe in a holistic and sustainable approach to weight loss,” says Sally-Ann Turner, MD. “Phentermine can be a helpful tool for some clients, but it’s essential to take it responsibly and in conjunction with a healthy diet, regular exercise, and ongoing weight health support. We empower our patients to make lasting lifestyle changes that will benefit their health and wellbeing long after they’ve stopped taking medication.”

Our clinical team works closely with each patient to develop individualised strategies for managing hunger, controlling portions, and maintaining motivation throughout their weight loss journey. We also focus on teaching practical skills that will help maintain results after completing the medication course.

Through our structured support programme, patients learn to make permanent lifestyle changes while using Phentermine as a tool rather than relying on it as a solution, and you can too.

Patients who have used a gastric band have undergone a significant change in their lives in the battle against chronic obesity.
