Why We Use

OPTIFAST® Products

Since 1974, more than a million people have successfully used OPTIAST weight loss products to achieve fast, effective, and long lasting weight loss.

The decision to use OPTIFAST products at the Evans Weight Loss Group came after carefully considering the many medical weight loss products available.  Only OPTIFAST was able to meet the standards of manufacturing quality, nutritional completeness, and proven effectiveness that Dr. Evans required.

OPTIFAST is regarded as the gold standard that other weight loss programs and products attempt to meet.  With over 80 clinical publications describing the effectiveness of OPTIFAST, and a clinical database tracking long term results in over 80.000 patients, OPTIFAST remains the most documented and trusted weight loss product available.

Regaining weight after dieting is extremely frustrating and unfortunately typical, but it doesn’t have to happen. Research shows that continued participation in a long-term weight management program or weight maintenance program can make a big difference in whether you are able to maintain your new weight. At the Evans Weight Loss Group, we offer weight maintenance programs designed to help you stay on track with your weight loss in the long term.

Ongoing Weight Maintenance Leads to Long-term Success

Their ongoing participation in our weight maintenance program is one of the major reasons that people in our programs are able to permanently lose weight

While attending our weight maintenance program, you will continue to have access to the expertise, resources, professional advice, and support of the Evans Weight Loss Group. This support will motivate you to keep practicing the healthy lifestyle that you learned during your weight loss program and give you an opportunity to learn even more skills you can apply to your healthy lifestyle.

Continued Access to Medical Weight Loss Products

Attending an ongoing weight management program also gives you the opportunity to continue to purchase the same medical weight loss products that you used during the active weight loss portion of your program.  Many of our patients continue to use medical weight loss products to replace meals as a simple way to control daily intake while maintaining high quality nutrition.

Flexible Scheduling

When you transition to an ongoing weight maintenance program, you do not need to attend weekly meetings. Most of our patients feel that a monthly visit provides them with the motivation and support they need to maintain their weight loss and healthy lifestyle. At those meetings, you will have the opportunity to assess your weight and body composition analysis and spot any trends that may indicate a problem. At these meetings you will receive the support you need to correct those unhealthy trends quickly before they impact your long-term health.

Ongoing weight management is an essential part of permanent weight and we strongly recommend that you participate in our ongoing weight loss program as part of your program. Our weight management program helps ensure you see long-term results for your hard work. If  you are ready to change your life, lose weight and regain your health, contact  the Evans Weight Loss Group in Tinley Park or Aurora, Illinois for a free, no obligation consultation.

Behavior Change = Weight Change

You already understand that if you change your diet and increase your activity, you will lose weight. However, if you’ve tried conventional diets before, you also understand that when the diet is over, the weight returns. You may have even regained more weight than you lost on the diet, leaving you in an even worse situation. The only true answer to permanent weight loss is to change the way you think, feel and react to food. You need to change your behavior so that when the diet ends, those behaviors have become a permanent part of your lifestyle, enabling you to make healthy choices for life.

Lifestyle change Leads to Long-term Success

Your weight is a result of your lifestyle. How you live influences all of the decisions that you make regarding the types and amounts of food you eat. Many of us use food to improve our moods, to deal with stress, or as an excuse. These ways of coping develop into deeply rooted habits that require you to develop strong and effective strategies to combat them.

When you participate in one of our programs with the Evans Weight Loss Group, you will meet weekly with a trained behavioral therapist, individually or in a group setting, to discuss weight, food, and health-related issues. When you better understand how food and overeating impacts your life, you better understand how to adjust your behavior to eat sensibly and for the right reasons.

Change Doesn’t Have to be Difficult

Many of us have tried to change our behaviors in the past without much success. But before you can successfully make a specific behavioral change, you need to learn the skills to make changing easier and more effective. With the skills that you will learn in our program, you will be ready to tackle any behaviors that affect your weight or other parts of your life. When you change your behavior, slipping back into old habits that resulted in past weight gains is no longer a possibility. Once you make these types of permanent changes, you can finally break free from the typical cycle of yo-yo dieting.

Permanent weight loss is possible through a plan of diet, exercise and behavior change. We can help you build the skills you need to make your weight loss permanent.

The second step in the Evans Weight Loss Group program is exercise. Current research shows that while weight loss is achieved through controlled dietary intake, the most effective way to maintain your weight loss is to continue exercising and to periodically increase your physical activity. In addition to helping you control your weight, exercise has a wide variety of health benefits and no healthy lifestyle is complete without it.

But I Hate to Exercise!

You are not alone. Many American feel the same way. Exercise is not as popular as it deserves to be. Recent data shows that less than half of the American population engages in some form of regular exercise. But if there is a fountain of youth, it is sensible, frequent exercise.

If you are like many people, your experiences with exercise have been unpleasant and likely monotonous. The idea of exercise may conjure up images of hours spent grinding away on a treadmill. Usually there is something else, or even a lot of things, that you would rather be doing. It’s true, there are a lot of things in life vying for your attention that make it challenging to find time to exercise-especially when you don’t like exercising anyway. But it doesn’t have to be like that. You can enjoy exercise.

We can show you how you can exercise without even realizing it. Our certified exercise physiologists will help you find activities that you enjoy and provide you with a customized strengthening and conditioning plan that will help you enjoy these activities even more so you grow stronger and healthier.

Why do I have to exercise if I am already dieting?

By exercising, we program the body to start working toward better health, better fitness and a healthier lifestyle. We teach our bodies what feeling healthy feels like. In addition, exercise will help you burn fat quicker without breaking down muscle, which is a vital part of safe and effective weight loss.

You will start to become fit after the first day of exercise.  As time passes you will realize that you are capable of doing things physically you never thought possible and daily tasks will become easier.

Customized Exercise and Activity Plans

As part of your customized program with the Evan Weight Loss Group, our certified exercise physiologists will design an exercise program that will fit into your lifestyle.  Regardless of your age or physical condition, we can design a simple, well-organized program for you that will produce results. You won’t need high tech equipment or a gym membership. We will help you begin to build the muscle and strength that is a critical part of the overall process of permanent weight loss.

The Evans Weight Loss Group is a medically supervised weight loss clinic that uses medical weight loss products and FDA-approved medications that are only available by prescription.

Your personalized weight loss treatment plan is evaluated and adjusted each week to ensure that you achieve steady weight loss. The Evans Weight Loss Group is also qualified to prescribe the latest weight loss medications and appetite suppressants, if necessary, to assist in measured, monitored weight loss.

The Evan’s Diet program is founded on clinically proven principles that have shown why diets that don’t “reprogram” the body’s metabolic and digestive processes don’t work in the long term. Our program, in contrast to commercial diet programs, is crafted specifically for you and designed to reprogram your body to eat efficiently and utilize fat for energy.

Expect Immediate Results!

Most of our patients experience a 5-8 pound weight loss in their first week on the program. Patients find that the consistent weight loss they experience each week motivates them and helps them to stick with their treatment plan. It can be a very thrilling process. Many of our patients report that using the medical meal replacement products to supplement or replace a normal food diet makes adjusting to lifestyle changes easier in the beginning of the program.

A Simple and Effective Dietary Program

Meal replacement products provide complete, balanced nutrition with precisely controlled amounts of calories.  This allows you to meet your nutritional requirements each day while losing fat weight and not muscle weight. Our usually patients find medical meal replacement formulas simple and easy to use and often continue to use these products after the initial weight loss program as part of their long-term weight maintenance strategy.

Safely lose 2-7 pounds per week until you reach your weight loss goal

A full meal replacement program uses a nutritionally complete, portion controlled meal replacement formula that provides all of the nutrition you require to safely lose weight. Using a combination of shakes, soups, and bars, we replace your normal meals with smaller, more frequent meals that eliminate feelings of hunger and are reported by most patients to be easy to adhere to.

How Long Does it Take?

A traditional full meal replacement program lasts 18 weeks.  The first 12 weeks are the active weight loss phase during which you will consume five or more shakes, snack bars and soups each day. During the last 6 weeks of the program, you will slowly transition back to a conventional foods diet. The exact duration depends on the amount of weight you wish to lose, your starting weight, and any existing medical conditions that you may have. Weight loss from 50 to 150 pounds is often seen using this program.

What to Expect

Although some people are skeptical about their ability to follow a full meal replacement diet, adjusting to this way of eating typically only takes about one week. Dr. Evans may prescribe appetite control medications to assist you through the initial first few days of the program. Afterward, many patients report they feel more energetic than they have for a long time.

Because of the large amount of weight loss possible with a complete meal replacement program, Dr. Evans will also monitor your health each week and adjust the doses of any   blood pressure, diabetes, and cholesterol-regulating medications you are currently taking as you lose weight. Most people who participate in a full formula diet are able to significantly reduce and, in many cases, eliminate medications used to treat weight-related diseases as they achieve a healthier weight.

If you are like many of our patients, your experiences with weight loss are filled with hardship, hunger, and the frustration of failure. The weight loss field is full of confusing options, yet the majority of commercial weight loss programs are ineffective in the long term. When you’ve tried several of these different programs and failed, you naturally feel reluctant to try again, despite any lingering weight-related health issues you may experience. You understand that you must lose the weight, but you just don’t know how to make it happen.

The Evans Weight Group shares your frustration with the empty promises and lack of results that you have experienced elsewhere. That is why we offer you a medical weight loss program that produces realistic weight loss results, improves associated medical conditions and helps you learn to make healthy lifestyle changes that will last a lifetime.

As your medical weight loss team, we work with you to address every aspect of the complex conditions of overweight or obesity. Non-medical weight loss systems don’t have the experience, expertise and resources necessary to provide a comprehensive, long-term solution for overweight or obese individuals. We provide that type of comprehensive, long-term solution. At the Evans Weight Loss Group, we help you identify the physical, emotional, and medical issues that caused you to gain the weight initially and that may be holding you back from losing the weight through more traditional diet channels. Once we’ve identified those issues, we can develop a complete treatment plan to resolve them and help you build a new healthy lifestyle.

Dr. William Evans is committed to using his medical training in bariatrics (the medical treatment of obesity)   to help you lose weight and improve your health. Under Dr. Evans’ supervision, you can expect to achieve rapid, safe medical weight loss while making lifestyle changes that will help you maintain your goal weight in the future.
