I started MFP in Jan 2011 as a New Year's resolution at 185 lbs. By February 19 I was at 175 and for whatever reason, I stopped logging in. 18 months later, July 4 2012, I came back and have been working diligently at this using Medifast. Here are my stats for this time period.

Starting: 7/5/12 191.6 (18.1 lb gain since the last time I logged in)
Week 1: 7/10/12 185.6 (6 lb loss)
Week 2: 7/17/12 183.6 (2 lb loss)
Week 3: 7/24/12 180.0 (3.6 lb loss)
Week 4: 7/31/12 178.0 (2 lb loss)
Week 5: 8/7/12 177.0 (1 lb loss)
Week 6: 8/14/12 179.2 (2.2 lb gain)
Week 6.5: 8/17/12 174.4 (4.8 lb loss) ~Change weigh-ins to Fridays
Week 7: 8/24/12 173.0 (1.4 lb loss)
Week 8: 8/31/12

My goal is 140 lbs. as the military put me at 142 for my maximum weight (for my age and height). If I hit this, it will be the first time in my16 year military career I will make weight.

MEDIFAST WEEKLY WEIGH-INS:
Week 1: -6.0 pounds (193)
Week 2: -0.0
Week 3: -3.4 pounds (189.6)
Week 4: -3.6 pounds (186)
Week 5/6: -1.8 pounds (184.2)
Week 7: -2.2 pounds (182)
Week 8: -3.0 pounds (179)
Week 9: -2.0 pounds (177)

Week 11: -2.4 (172.4)
Week 12: -2.2 (170.2)
Week 13/14: -1.8 (168.4)
Week 15: -1.8 (166.6 2 days early)
Week 16: -2.2 (164.4)
Week 17: -0.6 (163.8)
Week 18: -3.2 (160.6)

I'm only on week 2.5 and I'm about 3-4 lbs a week. I think week 3 will only be a 1-2 lbs loss.

First week back - I lost 10! I'm still shocked as I've never lost that much weight in one week before.

I seem to be a "party of one" on this board, but that's ok:)

Down 4 more, total of 16!

You are doing Great!!

Medifast used to advertise "UP TO 2 to 5 pounds" per week. They no longer make this claim because (litigation) proved that people will interpret this many ways. For me, the "up to" jumps out and places these numbers in context as best case scenarios. Regardless of the plan, there are so many individual factors that contribute to what weight loss will be for everyone at any given time. There will be times when people go off plan and still lose weight, and there will be times when people follow the Quick Start Guide parameters and do not lose weight. I find it most useful to measure my success against my own success. That is, I track my weight loss (as well as activity level, sleep, stress, and menstrual cycle) over a period of time and note what is normal for me. When something seems awry, I can go back and look at what things I may have done differently. Sometimes it jumps out (like starting a running program) and other times it's more subtle, such as the fact a 170-pound body that has been on the plan for a year and lost 125 pounds will not lose weight the same as a 296.5 pound body just starting the plan.

Week 1-7 posted above. Septembers numbers:

Week 8: 08/31/12 168.0 (5.0 lb loss)
Week 9: 09/07/12 169.0 (1.0 lb gain)
Week 10: 09/14/12 165.0 (4.0 lb loss)
Week 11: 09/21/12 163.0 (2.0 lb loss)
Week 12: 09/28/12 162.2 (0.8 lb loss)

So I am on average of 2.5 per week.

Weeks 1-4: (-9.4), (-6.4), (-3.6), (-2.2) Total: -21.6
Weeks 5-8: (---), (-5.6), (-2.4), (-5.0) -13.0, Total: -34.6
Weeks 9-12: (+ 0.8), (-3.8), (-2.8), (-5.4) -11.2, Total: -45.8

Haven't been in this forum in a bit. Just a quick update - 8 weeks, 32 pounds lost! Medifast really DOES work but you have to commit. Some days my commitment is VERY tested, but it's worth the effort.
