Get Customized Low-Calorie Diets At Our Kitchener-Waterloo Clinic

When you want to lose the excess weight and improve your overall health, don’t be afraid to get a helping hand. At the Dr. Seagrist Diet Clinic, we offer a medically supervised weight loss program that uses a healthy low-calorie diet which is customized to our clients in Kitchener-Waterloo and Woodstock. Over the last 10 years, we have helped clients throughout the community experience 15-20 lbs of weight loss per month.

How It Works

When you come to our clinic for the first time, we will discuss your weight loss goals and spend an hour reviewing your past medical history. We will use this information to optimize a personalized diet plan that will help you burn up to 3000 calories of body fat each and every day and won't leave you feeling tired or hungry. Your diet will be changed as your body starts to break down body fat, to give you the best chance of succeeding.

The program is a low-calorie diet of regular grocery store foods that are well-balanced. You can eat a wide range of meat, chicken, seafood, dairy products and unlimited vegetables. The diet is supplemented by vitamins and minerals administered both orally and through injections, including Vitamin B shots, to make sure you are getting your proper nutritional requirements.


Once on your weight loss journey, you’ll visit our clinic three times a week on Mondays, Wednesdays and Fridays in Waterloo, or Tuesday, Thursday, and Saturday in Woodstock. We will perform a weigh-in, review your diet journal and conduct a urine analysis to make sure that you are burning body fat. We will also provide counselling and B shots so that you know that you are being supported every step of the way.  For those who can't make it in 3 days a week, ask us about our alternative plans!  Call us at 519.570.3330 in Waterloo, and 519.290.2931 in Woodstock to find a diet plan that works for you!


Dr. Seagrist understands that a long term diet that utilizes strictly control foods will be less likely to succeed. This is why his diet uses regular foods you’ll find at your local grocery store. Dr. Seagrist and his staff are committed to offering continuous support and guidance combined with a maintenance system that will ensure that those lost pounds will stay off.

Our Fees

The initial consultation needs to be scheduled in advance. It takes about 1 hour. We will review your medical history and get your blood pressure, height, weight, and measurements to get started. We will also go over the diet manual, including all the foods you can have and cannot have on the diet. You will also receive a recipe book, and a sample of all the different protein products that we carry at the clinic. The fee for this is $158.28 taxes included.

You can purchase two weeks or one month on the diet (including shots). Two weeks on the diet costs $314.94, and one month on the diet is $594.38 (both including HST).  For alternative plans with less frequent visits per week, please call our clinics in Waterloo:  519.570.3330, or Woodstock: 519.570.3330.
