As a weight loss expert, I have seen many patients struggle with their weight and turn to prescription medications for help. These medications, when used for more than 12 weeks, have been proven to cause significant weight loss compared to an inactive treatment. However, it's important to understand that these medications are not a magic solution and should always be used in conjunction with lifestyle changes for the best results. There are various types of prescription weight-loss medications available, each working differently to help individuals lose weight. Some are meant for short-term use, while others can be used for longer periods of time.
It's important to note that these medications do come with potential side effects, so it's crucial to work closely with a doctor when taking them. One of the most commonly used weight-loss medications is phentermine. Originally used as a short-term medication, it has now been added to long-term therapy guidelines. Studies have shown that patients can lose around 5% of their body weight by taking phentermine. In the US, it is available in the HCl formulation in concentrations of 15 mg and 30 mg. While phentermine can be effective on its own, it has been found to be even more effective when combined with another medication called topiramate.
This combination helps decrease appetite and cravings, leading to greater weight loss. Other recommended medications include diethylpropion and the newly approved Zepbound. It's important to note that these medications should only be part of a comprehensive weight-loss plan that includes healthy eating, physical activity, and behavioral changes. They are meant for individuals who are obese or overweight and have not been able to lose enough weight through diet and exercise alone. However, not everyone is suitable for taking weight-loss medications. A person must have a body mass index (BMI) of 30 or more, or a BMI of 27 with a weight-related health problem such as diabetes or high blood pressure.
Additionally, the cost of these medications may be a barrier for some individuals, as insurance companies may have their own eligibility criteria or require phased therapy with oral medications. When working with patients, I always perform a thorough evaluation to understand all the factors that may contribute to their weight problems. I believe in treating obesity as a disease and use lifestyle modifications, such as teaching patients about proper nutrition, exercise, and behavior modification. We also discuss sleep habits and managing mental health, as these can also play a role in weight management. It's important to understand that our bodies are not programmed to lose weight easily. This is due to our caveman ancestors' metabolism, where weight loss was seen as a danger.
This phenomenon is known as metabolic adaptation, where hunger increases and metabolism slows down over time when someone starts to lose weight. To combat this, I always advise my patients to maintain their muscle mass and metabolism by consuming enough protein, exercising regularly, and incorporating strength training into their routine. While the information provided on government websites such as niddk.nih.gov may not be updated due to current restructuring, it's important to note that health professionals use body mass index (BMI) to define overweight and obesity. A BMI between 25 and 30 is considered overweight, while a BMI of 30 or more is classified as obese. Calculating your BMI can help determine if you are at risk for health problems related to your weight. If you are struggling with your weight, it's important to work with a healthcare professional who can evaluate your individual risk factors and create a personalized plan for you.
In most cases, a healthy eating plan and regular physical activity can help with weight loss. However, if these lifestyle changes are not enough, your doctor may prescribe medications as part of your weight management program. Obesity is a chronic condition that affects a large portion of the population. Prescription medications for weight loss work in different ways, such as suppressing appetite or inhibiting fat absorption. They are meant for individuals who have health problems related to being overweight or obese and should always be used in conjunction with lifestyle changes for the best results. Studies have shown that weight-loss medications are most effective when combined with a comprehensive lifestyle program.
If you are considering taking these medications, be sure to discuss all your options with your healthcare professional and find a program that works best for you. Remember, these medications are not a substitute for healthy eating and regular physical activity, but they can be a helpful tool in achieving and maintaining weight loss.
