I have been a member of medifast for years. They guarantee weight loss. The office personnel is very friendly. They are always willing to help you as you go on the weight loss journey. In the beginning the program is a little expensive but it is truly worth it. I would recommend asking for samples before you buy in bulk due to the taste. If there is something you do not like work with your consultant to make an exchange. They want you to stay on plan so they are very accommodating. You will be required to submit a blood test and complete an in-body assessment. They will also take your measurements with a before photo. Overall this is a great location and i would recommend it to a friend beware the foods can seem pricey but you paid the price to get overweight. So you have to pay the price to lose it.
