"Over the past year, with the support, guidance, and encouragement of Dr. K. and Matt, I have learned about the caloric value of food, increased my metabolism, learned new coping skills, and oh, yeah....lost over 85lbs. This hasn't been just about weight lost; it is also about all that I have gained: self-confidence, a new outlook on life, and a physical and emotional strength that is enhancing every area of my life."   - Beth J

"Though these pictures make us look good, the battle is still ongoing.  Keep up the diet, exercise and mind set and you'll make it for a life time."   - Al P

"Before starting the Optifast program, I reached an all-time high for my weight and my life seemed to be spiraling out of control. I knew I had to do something. My primary care physician referred me to Dr. Keroack. When I first met with him and saw how understanding he was, I knew I'd come to the right place. I lost 11 lbs. in the first week giving me the motivation to continue. I lost 87 lbs. in 18 weeks and have kept it off for three years.

The Optifast program is more than just a weight loss program. It helped give me the boost I needed to regain control of all aspects of my life. I now run road races and will be running in my first half marathon in a month. I am also starting to train for a triathlon. I hope to, one day, complete an Ironman Triathlon. I would never have been able to do this before.

The staff at Pioneer Valley Weight Loss Centers is one of the reasons I have continued to be successful. I am continually asking them questions and they are always willing to assist me in any way they can." - Jeff C

"I have dieted for decades, peruse a myriad of health/nutrition newsletters and books, and happily order the plain fish with steamed veggies in restaurants..... honestly preferring my simple fare to the goopy dishes surrounding me. Yet over the last couple of years none of my (many) old tricks would work. I despaired as my columns of recorded morning "weigh-in" declared the unpleasant reason for the snugness of my larger clothes and the sluggishness I felt. In desperation I received counsel from Dr. Keroack in advance of technically breaking the "obesity cut-off", and to my amazement his program instantly and dramatically reversed the trend! Thank you so much!" - Esta F
