Meet Your Practitioner

Hi I'm Abby de Gouveia! I was raised here in East Tennessee and after getting married and moving away for six years in the Pacific Northwest, I'm delighted to be back home. I'm excited to share my passion for health and weight loss with my family and friends in East Tennessee. I was born in El Paso, Texas, but grew up in Tennessee. I attended ETSU for my undergraduate degree and Lincoln Memorial University-DeBusk College of Osteopathic Medicine for my master's degree. I enjoy urgent and emergent care, but my other passion is assisting individuals in reaching their weight loss goals. The bonds you can develop in a short period of time and the joy you bring to people’s lives make it all worthwhile for me. I want to assist people in losing weight in a safe, healthy, and medically controlled manner.

When I'm not working with patients, I'm lucky enough to be married to a fantastic man and have one gorgeous daughter. We enjoy hiking, traveling, playing board games, and anything else that involves spending time with family. I also enjoy music; singing and playing the violin are two of my favorite ways to unwind.

Frequently Asked Questions

1. How much weight could I loose?
On average, people can lose up to 15% of their body weight. Obviously ever individual is different so we customize your plan to optimize your results.


2. What are the medications that Foundation Slim provides? 
The medications our doctors prescribe are called GLP-1s (glucagon-like peptide-1s).

The GLP-1s are clinically-tested, stimulant-free, and non-habit forming. GLP-1s address the underlying biology that is most important for weight loss, and help lower your set point, or the weight your body fights to stay at. GLP-1s are powerful, naturally-occurring hormones made by your gut that send signals to your brain to decrease your appetite, improve your metabolic system, and regulate your digestion so you can feel full longer and maximize nutrient absorption.


3. Can I get my insurance to cover the cost? 
We encourage people to discuss GLP-1 weightloss programs with their family doctor and insurance company.

For most people, insurance companies don't cover the cost of the medication without an approved diagnosis.

Our program is designed to be a cost effective alternative for people who are not covered by insurance and includes all the medications and supplements in the cost.

4. Who is eligible to join the program?
Are between 18 - 75 years of age

Have a BMI that is >30, or >27 with one or more of the following metabolic conditions: diabetes, pre-diabetes, high cholesterol, high blood pressure, cardiovascular disease, non-alcoholic fatty liver disease, obstructive sleep apnea or PCOS.

Who are not pregnant or breastfeeding

Who do not have an active substance abuse problem, an active eating disorder (e.g., anorexia or bulimia), type 1 diabetes, cancer, recent bariatric surgery (within the past 18 months), active gallbladder disease, a history of pancreatitis in the past six months, or a history of medullary thyroid cancer (MEN syndrome)

5. What can I eat on the program?
We’ll never restrict your diet. Instead, we’ll help you rebalance it. Our approach to food is flexible and works with nearly all dietary restrictions, including gluten-free, kosher, vegan, and lactose-free (to name just a few). We will help you establish a sustainable and flexible approach to nutrition that focuses on minimizing fast-digesting carbs and making healthier choices that include protein, fiber, and healthy fats—without restricting or counting calories.

Our food program is not a diet: we do not use meal replacements or offer meal plans. We don’t try to restrict your eating: instead, we help coach you to rebalance it.

6. What will my virtual doctor visit look like?
Your initial doctor appointment will take place via video and last 30 minutes. During this appointment, your doctor will review your health history and lab results with you, and make recommendations for your treatment plan. If you have any questions about the medications that we prescribe, your individual health history, or what your program might look like, you can ask your doctor these questions during your appointment.

7. How is your program different than every other diet I have already tried that doesn't work?
Our program is doctor-guided designed and supported by the leading experts in obesity treatment.

Research shows that GLP-1 medication combined with lifestyle intervention is the most effective weight approach to sustained weight loss. Our program includes personalized 1:1 coaching and and ongoing medical support to drive better results for clients.

Our program is based on GLP-1 medications only.

Unlike other programs, our doctors will never prescribe dangerous stimulants. That's because GLP-1s are the safest and most effective for sustained weight loss.

There are no sweeping restrictions or calorie counting. Together with your coach, you'll make small, gradual lifestyle changes that ladder up to big results that you can sustain long term.
