"I would like to highly recommend Marcia Upsons' weight loss program, Naturally Slim. This is an excellent program that provides weight loss in a safe and effective manner. This program stresses making changes in eating patterns that ensure that weight lost is maintained.
Many of my patients are overweight and seek advice on weight loss. Unfortunately, diets and medications are not effective in maintaining weight loss over a long period of time. I recently attended a Naturally Slim course to learn more about the program and see if it really worked. Marcia is an excellent speaker who is extremely knowledgeable and motivational. Her program stresses making changes in your eating habits that allow a slow and steady weight loss. I think the most wonderful aspect of her program is that you can eat anything you want (except for sugar the first 3 weeks). There are no food restrictions or calorie counting. Therefore, you don't feel as if you are on a diet. Throughout the course Marcia also stresses a healthy lifestyle including exercise.
I would like to highly recommend Naturally Slim as a perfect solution to being overweight. I have been 15-20 pounds overweight and was able to lose 12 pounds over 2 months. Naturally Slim is a highly effective program and anyone who takes this program can be a success."

"The biggest appeal in my opinion for Naturally Slim is its healthy sensibility. Numerous patients have had great success and love the simplicity and flexibility. My strongest endorsement is that this is a lifestyle change, not a "diet," thereby encouraging long term maintenance and success. It encourages any schedule, no matter how busy, or how often you eat out, to be able to stick with it."
-Denise Bannister M.D.
"This program has helped my patients to eat healthy only when they are hungry. Naturally Slim helped them to loose weight and keep it off. It even helped regulate menstrual cycles due to weight loss as well as lowered blood sugar and cholesterol."
-Nirmala Vallurupalli M.D.
"Many of my patients have successfully lost and kept off weight on Naturally Slim."
-William Mania M.D.
"Naturally Slim, as a weight loss program is very effective. In contrast to various diet programs which seek to reduce weight through modification of type and amount of food, "Naturally Slim" assists the overweight to alter the fundamental relationship they have with food and develop what Naturally Slim characterizes as a slim mind. The program defines and reinforces a positive relationship with food while arresting the common diet weight gain cycle that these clients have often previously experienced and while assisting clients to remove food from their reactivity to various life issues and the emotional response they are having to these various life issues. In this process, the clients are freed from the biological variables that have been set up by dieting cycles and more direct coping strategies are taught to address the emotional triggers to excessive eating. Thus, in addition to losing the weight they choose to lose, the clients often become much more successful at dealing with difficult life issues.
Over the years, I have referred many clients to Naturally Slim and have seen first hand the program's success in achieving sustained weight loss and improve quality of experience."

-Camille Clark M.D.
"I have referred several patients to Naturally Slim in the last few years. The results have been very good. Even patients who did not lose a lot of weight still found it very worthwhile. The program really is a different, healthy way to look at eating and weight loss."
-Susan Rogers M.D.
"I refer patients to Naturally Slim because it offers teaching in diet modification that allows patients to lose weight and keep it off. With their weight loss and healthier life styles, they often can see benefits from medical problems including hypertension, diabetes, and high cholesterol."
