Is avista right for me?

All AVISTA weight loss plans are physician-supervised within a safe and effective program. Our clinicians, medical staff, and registered dietitians will guide you all the way. Here's the difference:


AVISTA's CLIA approved lab, private lab rooms, and highly trained staff help make testing convenient, comfortable, and reliable.

We perform an annual 5-panel blood test, 12-Lead EKG test, blood pressure test, total body composition test, blood fat analysis, urine analysis, mini-physical exam, and take digital measurements.

During the free consultation, we will decide if appetite suppression-medication or other supplements are right and select a medical weight loss plan.

Our in-house pharmacy makes prescription dispensing easy and convenient.

Weekly visits are encouraged. Come in and talk about struggles or successes, and if we need to, we can adjust the program.

AVISTA stocks high-quality injections, food, and supplements.

Plans for women

If you are looking for a weight loss program for women that works, you've found it.

Most of our patients are women, and we know women want to lose weight for very different reasons that are all very important. Some of the reasons we have seen from our women patients are medical concerns, not wanting to buy a new, larger wardrobe, wanting to get into "skinny" jeans, planning for weddings (planning for divorces), family reunions, summertime vacations or anytime vacations, pains in the knees, pains in the feet and pains in the neck, their other doctors told them it was time to get serious and just plain sick and tired of being sick and tired. But whatever the reason our women patients come in our doors, they have made a decision and are ready to lose that weight once and for all in a safe and reputable environment.

AVISTA Weight Loss Center provides the education and support you need to reach and maintain your goals. We have the resources to help you achieve your ideal weight and body fat percentage. We have specific weight loss diets for you as a woman. After evaluating your needs, we will start the move towards a healthier you! In addition, we know you have a busy schedule and are more than happy to accommodate you.

Our balanced program for women begins with initial testing (blood work, EKG, urine analysis) and a visit with one of our providers. The provider will give you a personalized reduced-calorie diet and appetite suppressants (if appropriate) from our in-house pharmacy. You will then receive an email each day with a suggested menu, shopping list, and recommended exercise regimen. When you get close to your goal weight, we will modify your custom meal plan into a meal plan for life to keep you at your goal weight.

Post Partum Plans

At AVISTA Weight Loss Center, we understand that time is limited for new mothers. Our goal is to help you drop that baby weight through our weight loss programs for women. We provide unique exercise programs and meal plans that help you reach your goals. New mothers can begin a customized weight loss program as soon as six weeks after giving birth.

Plans for men

If you are looking for a weight management program for men, you've found it.

We have wonderful, highly successful programs tailored just for men. Dr. Raman understands that most men desire to lose weight in their midsection. Recent studies have shown that abdominal fat is linked to a higher death rate, especially in men. Therefore, our weight loss programs for men helps you tone your abdominal area and lose both subcutaneous and intra-abdominal fat. We know that men who are overweight sometimes have low testosterone level – that's why we perform a total testosterone test on every single man in our practice.

We are aware of the unique obstacles and difficulties men face when it comes to losing weight, and our plan faces these challenges with a wide variety of foods, custom meal plans, and exercises.

When you meet with our provider, they will carve out a meal plan that will help you lose your weight at a safe and efficient pace. When you get close to your goal weight, we will modify your custom meal plan into a meal plan for life to keep you at your goal weight. Daily meal plan emails and daily exercise plan emails will give you the gentle reminders and direction you need to achieve your goal.
