Physician-Guided GLP-1 Medical Weight Loss

Transform Your Health with Physician-Guided Tirzepatide at American Fit

Weight loss is not simply a matter of willpower. Appetite, hormones, metabolic health, genetics, sleep, stress, and other biological factors can all influence your ability to lose weight and maintain your results.

At American Fit, we combine advanced GLP-1 medical weight-loss treatment with physician-guided care, personalized dosing, and ongoing support to help eligible patients work toward meaningful, sustainable progress.

Tirzepatide is a dual GIP and GLP-1 receptor agonist used in medical weight-management programs when clinically appropriate. It works with receptors involved in appetite regulation, fullness, digestion, and blood-sugar control.

By helping reduce hunger, increase feelings of fullness, and support improved appetite control, tirzepatide may make it easier to follow healthier nutrition habits without constantly feeling consumed by cravings or hunger.

American Fit offers more than medication alone. Every patient begins with a medical intake and physician review to determine whether treatment is appropriate. Approved patients receive an individualized treatment plan, clinical guidance, dose adjustments based on their response, and continued support from our experienced medical team throughout treatment.

Clinical research has shown that tirzepatide, when used alongside appropriate nutrition and lifestyle changes, can produce significant reductions in body weight over time. Results vary based on factors including starting weight, prescribed dose, treatment duration, medical history, nutrition, physical activity, and individual response.

Some patients notice improved appetite control during the first several weeks of treatment, while weight loss generally develops gradually as treatment progresses. Medication is typically started at a lower dose and adjusted over time based on tolerance, response, and physician guidance.

At American Fit, our goal goes beyond helping you reach a number on the scale. We are committed to providing responsible, evidence-informed medical care while helping you improve your habits, confidence, and long-term health.

Your journey begins with a medical evaluation, physician approval, and a treatment plan designed around your individual health history and goals.

FAQ

What is Tirzepatide?

Tirzepatide is a once-weekly injection that helps people lose weight by lowering appetite and improving how the body handles blood sugar and fat. It works by copying the effects of two natural hormones that help control hunger and blood sugar levels.

How does Tirzepatide help with weight loss?

Tirzepatide works in a few key ways:

Reduces appetite, so you feel full faster and stay full longer
Slows down digestion, which helps with portion control, which helps with portion control
Improves insulin sensitivity, which helps the body burn fat more efficiently
Reduces food cravings, especially for carbs and sugar

Who is a good candidate for Tirzepatide?

You may be a good fit if:

-You have a BMI of 30 or higher, or
-You have a BMI of 27 or higher with a weight-related condition (like high blood pressure or insulin resistance)
-You’ve struggled to lose weight with diet and exercise alone
-You've hit a plateau and can't seem to get stubborn fat off
-You’re looking for medical support to lose weight in a healthy, structured way

Our medical provider will help decide if Tirzepatide is safe and right for you.

How long does it take to see results?

Although results vary from person to person, most people start to notice changes in appetite and cravings within the first few weeks. Visible weight loss typically starts around weeks 4–8, and the most significant results happen over several months. Some fast responders notice appetite decrease within 24 hours and already see results within one week.

Do I need to diet and exercise while on Tirzepatide?

Yes. Tirzepatide works best when combined with a healthy diet, regular movement, good sleep, and hydration. It helps control your appetite, but long-term results come from sustainable habits. Think of it as a powerful tool, not a magic fix. It is best to implement healthy habits before taking Tirzepatide so that you can maintain these habits during and after taking Tirzepatide. It is crucial to stay hydrated and highly reccomended to drink protein shakes throughout the day to avoid losing muscle.

How is Tirzepatide taken?

It’s a once-a-week shot you give yourself using a small pen-like device. You can inject it into your stomach, thigh, or upper arm. Our medical provider or nurse will show you how to use it and can be easily done at home.

What dose do I start with?

Everyone starts Tirzepatide at a low dose of 2.5 mg once a week. This starter dose isn’t meant for weight loss just yet — it helps your body adjust and reduces the chances of side effects like nausea or stomach discomfort.

After the first 4 weeks, we’ll check in with you to see how you're feeling and how your body is responding. At that point, we may:

-Increase your dose to boost results
-Keep you at the same dose if you're doing well or still adjusting
-Hold off on increasing if you're experiencing side effects

We’ll reassess every 4 weeks to decide whether to move up to the next level: 5 mg, then possibly 7.5 mg, 10 mg, and so on — up to a maximum of 15 mg, depending on your goals and how you’re tolerating the medication.

Our goal is to find the lowest effective dose that helps you lose weight safely and consistently.

Do I need to follow a specific diet while taking Tirzepatide?

You don’t have to follow a strict diet, but eating a balanced, high-protein, lower-carb diet will help you feel better and lose more weight while avoiding losing muscle mass. Most people find they naturally want to eat less while on Tirzepatide, especially junk food or large portions.

What are the side effects?

While many people do not experience side effects on Tirzepatide due to starting at an introductory dose, the most common side effects are related to digestion, especially when starting or increasing the dose such as nausea, bloating, constipation or diarrhea, heartburn, and low energy (at first). These usually improve as your body adjusts. Eating smaller meals and staying hydrated helps a lot.

Can I stop Tirzepatide after I lose weight?

Yes, but it is best to talk to our medical provider first. Some people choose to stay on a low maintenance dose to help keep the weight off. If you stop, it’s important to have solid habits in place (like meal planning and regular movement) to help prevent weight regain.

What happens if I miss a dose?

-If you miss a dose but remember within 4 days, take it as soon as possible.

-If it’s been more than 4 days, skip the dose and take your next one on your regular day.

Don’t double up!

Is Tirzepatide safe?

Tirzepatide is generally safe for most people, but it’s not recommended if you have:

-A personal or family history of thyroid cancer (medullary thyroid carcinoma)
-Multiple Endocrine Neoplasia type 2 (MEN2)
-Certain digestive or pancreatic issues

Our medical provider will screen for any risks before starting.

Will I gain the weight back if I stop taking Tirzepatide?

Possibly — especially if old habits return. Tirzepatide helps with hunger and portion control, but long-term success depends on building lasting habits. That’s why combining the medication with a healthy lifestyle is so important.

Will Tirzepatide make me lose muscle?

Like with any weight loss, there’s a risk of losing some muscle mass — especially if you’re not eating enough protein or skipping workouts. To protect your muscle:

-Eat plenty of protein and/or supplement with protein shakes throughout the day
-Stay active, especially with resistance or strength training
-Stay hydrated and support recovery

How long do I have to take Tirzepatide?

There’s no one-size-fits-all answer. Some people use it for a few months, others for a year or longer. It depends on your goals, your progress, and whether you want to use a maintenance dose to help keep weight off. American Fit will help create a plan that works for you.
