  2. This incredibly powerful weight loss medication will facilitate and speed up your weight loss journey.
  3. Only available with a prescription, the medication helps decrease your appetite but it also increases your energy and that means your metabolism will speed up.

Fat Burning Injections

  1. We offer highly effective fat burning injections at our OC Weight Loss Centers. They stimulate weight loss to remove fat cells while helping rid your body of stubborn fat so you can look and feel leaner.

*There are so many out there, and they seem to be all about the $$$. I didn’t know how to find a genuine one… glad I chose this place! This is a family-owned kind of place and the doctor is super nice – really takes the time to understand your situation and personalize the treatment. She’s actually been through the treatment herself too, so you can see the results. Staff is cool and overall it’s just really easy…and EFFECTIVE! If you’re looking for a HEALTHY weight loss solution, I highly recommend!

*I needed to lose 30lbs and my various diets and cleanses were failing. A good friend recommended Dr. Kakar. She is extremely knowledgeable and I felt at ease knowing that she had gone through the treatment herself. My diet plan was personalized based on reads from various tests that were performed before the treatment was started. I feel blessed to have found OC Weight Loss Centers since not only did I lose the 30lbs in a month but have kept it off the last year with support from Dr. Kakar and her staff. I look and feel great and highly recommend this place to anyone who wants to lose weight, whether it is 10lbs or 100lbs!

*My experience with OC Weight Loss was amazing! I was able to lose 63 lbs so far in 6 months and have kept it off with the support of Dr. Kakar and Marjan. I was given 3 choices of diets in the initial consult, so I never felt like I was forced into some cliche diet. As a matter of fact, In the past 6 months I haven’t even felt like I’m on a “diet”, yet the pounds continue to shed! After trying a few different “franchises” and crazy diets, I am so glad I finally found OC Weight Loss Centers. Thank you!!!*
