What is the Medi-Slim Diet?

The Medi-Slim diet is a medically designed and supervised weight loss program created to help you make healthy lifestyle choices to reach and maintain your weight loss goals.*

What better diet than one designed by a medical doctor? Dr. Ali and his medical staff are trained to understand any health conditions and will guide you through the program to help achieve the results that you expect.*

You can expect to look and feel great and have more energy!*

How Does it Work

Our weight loss program includes three components, a diet plan, an exercise routine and behavioral counseling. One of our trained medical staff, a physician, or a physician assistant, will review your medical history, perform a complete physical examination, and then recommend an appropriate program that best meets your goals based on your health condition and lifestyle.

When indicated, an EKG or a blood test including thyroid hormone, lipid profile, and screening for diabetes may be recommended based on your health status.

You have Choices!

You can choose between high-protein low carb, low calorie, or a vegetarian diet.

What can You expect?

Upon arriving at one of our weight loss clinics , Medi-Slim Wellness Rancho Cucamonga or Medi-Slim Wellness Claremont, our trained medical staff will calculate your Body Mass Index (BMI) and Ideal Body Weight (goal weight) based on your age, height, and gender.

For the next 20-30 minutes, you will attend a lecture by a physician or a physician assistant to go over the details of the program, explain the process step by step, and answer any question you might have. We'll walk you through the process step by step, provide you with detailed food items allowed, and even give you a food menu and great recipes for your meal plan.

Your first visit is only $1, and we even will give you two vitamin B-6 injections free, just for coming, no obligation. There are no long-term contracts, no special food to buy. We surround our program with support and service that will make your weight loss journey a success.*
