BACKGROUND

The OPTIFAST plan has been considered the ace of liquid-based diets since 1974. The meal replacement drinks and bars are recommended by physicians for patients weighing more than 50 pounds over their ideal weight or with a Body Mass Index (BMI) of 30 or more. OPTIFAST is recommended to help obese individuals prepare for gastric bypass surgery as well. All participants have full access to professionals like doctors, dietitians and counselors.

The OPTIFAST program follows strict guidelines to ensure the health and safety of patients with three key areas of concentration - medical, behavior and nutrition. Patients have an initial medical exam to make sure they meet the program criteria.

Progress is monitored during weekly one-on-one and group counseling, to help encourage healthy lifestyle changes.

PRO
  • People will lose weight on the introductory phase
  • Your weight loss is monitored by their experts
  • Proven results with clinical studies and over 1 million participants
  • Program gives support and counseling along with weight loss
  • Medical monitoring while on the program
  • Offers decrease in cholesterol, high blood pressure and high blood sugar levels
  • Great tasting meal replacement shakes
CON
  • Doubtful that most health care professionals would recommend being on a meal replacement plan for any extended period of time
  • Program consists of all liquid diet
  • May be cost prohibitive for some
DIET and NUTRITION

To participate in Optifast, you must first complete a preliminary medical exam. You will be assessed to determine any risk factors and make sure you are a good fit for the program. After passing that exam, you are given a personalized weight loss plan that is based on your current weight and your goals. You are monitored throughout the entire process. Your meals will consist of the Optifast shakes and meal replacement bars.

EXERCISE

You get a customized activity plan for your fitness level and schedule.

CONCLUSION

Maybe the OPTIFAST meal replacement is nutritionally sound, but there are plenty of other programs that have you making sound choices with real food. This program is also very expensive. This combination can only lead to the conclusion that there are other choices that would come before OPTIFAST.

Im in Australia and, like New Zealand, its available over the counter in chemists and for about $45.
When I was younger I used to do Optifast constanly on and off when I wanted to drop a few kilos in a week or 2 weeks... would usually lose about 3kgs a week without exercise (which is excellent considering I used to weigh only about 55-57kg)...
Have now gained alot of weight and am looking to lose about 15-20kg... so am now on day 4 of Optifast and hopefully I can pull it off! :)

I had always been in sports and always active! I had my daughter 2 years ago. I weighed 135lbs. when I got pregnant, I didn't eat "a lot" b4, but was forced to eat 3 meals a day (at least) while pregnant or I was consistantly sick. (My doc. thought I was having twins-what a confidence boost!). My daughter is 2 years old now, and I still weigh what I did after I had her...200lbs. Talk about not wanting anyone to see you! I had a lot of probs. after I had her and wasn't physically able to exercise. Being this large I am now on a "mission" to lose this weight! I am at the point that I HATE food! No, really I barely eat! And I can't lose anything. I've always been athletic, skinny, but ever since I had my daughter, this fat is "stuck" on me! I'm depressed and can't stand for anyone including my husband to look at me, let alone do anything else with me...My first session is 2/18/09 and I am hoping this will help, I would do anything! If I had the money I'd have everything nipped ,tucked, and sucked out of me. I have read the success stories...I HOPE I am one!!!

I did a similar program at a clinic. It is great because you can treat food addiction by abstaining from it while learning new eating behaviors in class & groups. The re-gain rate is high IF you do not attend a maintenance program for a year or two after stopping the shake phase. I work with people who did Weight Watchers or TOPS after the shake phase b/c these programs are less expensive. Both have kept off 60lbs+. You are not hungry at all after the first 4 days. Best plan I've ever done.

I have been on the program for two weeks now, my first week I lost 6.3 lbs waiting for my next weight in every Monday. I also encourage the attaining the group sessions very informing. It's a very motivated program, you have to have the will power. I have my first shake at 9AM, Noon, have a piece of fruit at 3PM and dinner at 6PM with my last shake at 9PM plus taking my vitiams, calcium & fiber in the morning. Good luck to eveyone..

Yes, my insurance pays for the program without it I would had to try a different source. I just pay for the product and Doctor visits as required.

I lost 65 lbs using Optifast from August 07 - December 07. As of today (Dec 30, 08) I have gained 40 lbs of it back. I start again at the top of the year. Once off the fast this time, I plan to begin a workout regimen.

The Optifast diet will help you lose weight, but in the end it is up to each individual to change eating patterns and behaviors. I was on the Optifast program for about 5.5 months and lost 35 pounds. The first week was horrible, depressing and everywhere i went all i saw was food. After my first weight in i lost 13 pounds, i was so motivated. After the second weight in i lost 2 pounds, i was angry. I followed the plan exactly as my doctor said but i was losing 4 pounds there 3 pounds here. I still kept with it though and the weight loss allowed me to start excercising again. It wasn't only about the weight loss, my whole attitude about food and eating changed. I use to walk by my favorite restaurants and wouldn't even notice them. I missed eating real food so much that when i did start eating again i had no problem eating vegetbales and other "healthy" foods. Unfortunately i gained all the weight back because i stopped goign to my doctor and did not finish the program. It got to the point where it was either optifast or rent and gas money. My doctor would charge $70 every visit just for the weekly weigh in. He charged about $50 for the phentermine and $20 for the laxatives. It got to be too much money. I place the blame on myself for gaining my weight back because i fell into my old traps again and i didn't make time to excercise. If you are really overweight and need to lose a lot of weight, this diet will help you but it is very expensive and mentally challenging. If i could find a less expensive doctor or avenue i would def go back to it again to lose what i gained back. Good luck to all!

Dr. Primack

When using Optifast as formulated and directed, you should not need any other supplements (such as potassium or magnesium). It is already added to the shakes and soups.

One of the benefits of seeing a physician for weight loss is as these or other concerns arise, you have a knowledgeable souce for information.

wo fat

the first time i did it i lost 35 pounds in 6 weeks, over the next 2 years i put the weight back on so did it again, same great results .
here in spain the product can be purchased over the counter.
when i did it in america the first time the price was obscene with the doctor as a middleman.
i think there were some online sites , so unless you have a medical condition other than being fat i recommend doing it yourself
remember to drink lots of water
i also take a multimineral as the water depletes your body of some of these.
another thing to remember is once you start a liquid diet and flush yout your digestive tract you will have lost about 8 kilos which is the amount of gunk we constantly carry with us
good luck

I have been on the program for 17 weeks. It should be medically supervised. Sandie, you might be having stomach problems because you need to take a potassium supplement. When you are on a fast such as Optifast, your potassium levels drop. One side affect is stomach problems, among others. For this reason and others, it should be medically supervised. It is also a complete weight loss program. When if done correctly, explores deeper topics such as food choices, body image, reasons and situations when one over eats, eating disorders, and many other topics. The weight loss part is just the begenning of the program.

I recommend it, but beware it is not easy to be on a liquid only diet with no food. Yet, the rewards are huge. I am a male and I am losing about 5-7 pounds per week. The first week was horrible. Afterward, I felt great. I play sports for about 2 hours now five times a week and feel great. I've lost 85 pounds and still have 50 to go. So, another thing to consider when trying to diecide if this diet is right for you is if you have a lot of weight to lose. I had over 100 pounds so this diet is good because it gives results fast. Remember though, you want to go beyond the quick results and change your eating habits and overall way of thinking if you want to maintain the weight off. That's why it is important to go through the entire program. Good luck to everyone!
