I can't wait to be on IP long enough to have numbers to average

So far very happy with my two weigh ins.

Over 2 months since starting, if everything is averaged, I lose 2.78 lb/week.
That being said, some weeks it's close to 5, some weeks it's only 1. But it all evens out in the end

You can see my losses in my signature - I had high weeks and low weeks all through the process!

One VERY important thing to remember is that your losses will slow down the closer you get to goal. The smaller you are, the less baseline calories your body needs to function. So there is a smaller difference between what you NEED and what you are EATING. The bigger the difference, the more dramatic the weight loss. We are already at the VERY low end of calorie intake so you do NOT want to increase that difference any more than it already is. Just rest assured that it's normal, and it means you are so much closer to hitting your goal!

Mine varies week to week (like most folks' losses) but my average since starting is 2.12 pounds per week overall.

Aside from the first weigh-ins, I'm losing ~2lbs per week.

Are you losing any lean mass or just fat? I'm also losing some lean mass.

Of course you're losing lean mass!
Lean mass is EVERYTHING that isn't fat.
So you'll lose skin & connective tissue you don't need anymore. My doc even reminded me that we lose tiny blood vessels we don't need anymore.

We all automatically think lean mass is muscle but it is everything else. And remember how much water we lose with every lb of fat!

A person will lose 1lb of lean mass (as lisa said, this is EVERYTHING but fat) for every 4lb of weight lost. This is NORMAL.

I started on Synthroid about 6 weeks ago, but after the reading I've done (2 books, 1 by a doc and the other called Stop the Thyroid Madness), I'm not happy I was prescribed Syntrhoid. It just tells me my doc really doesn't understand what is happening & is just going with what the pharm industry is telling him.
I went for my blood re-test last Thurs. I'm waiting for my email of the results & if I don't hear from my doc, I'll call the office. I don't want to just be "in range" I want to be optimal. I want normal thyroid functioning again and if he can't get to the cause of it, I'll find someone who will. There's a reason this happened at age (almost) 50.

I LOVE Sean's blog and podcasts. He has the most informative folks on! I haven't read his book. Right now I'm reading 8 steps to a Pain-Free Back by Esther Gokhale. She's a rebel. Rebels are my fav.

Gotta love thyroid issues!

I was just diagnosed three years ago as hypothyroid - turns out mine is caused by Hashimoto's disease, an autoimmune response that attacks the thyroid. Unfortunately in my case there won't be such a thing as getting back "normal thyroid function" because the damage has been done. But I take my meds and things have normalized as much as possible, it's just something I have to watch.

Autoimmune issues are nasty little buggers - my mother in law just joined the club, she suddenly developed autoimmune hepatitis at age 55 with no history of liver issues, no heavy drinking, nothing. Sometimes the body's defenses just go wonky.

I hear that. I thought I'd at least make 40 before everything went to he77 but I was 1 month away from my birthday when I was diagnosed with MS. Kind of ruins the whole milestone of a birthday.

Getting back to the original question. Today is day 28 for me and I'm averaging 4lbs per week based on the big dump from week 1. For the last 3 weeks I'm averaging 2.66.

I've been on it for almost 4 weeks and every weight in is about 7lbs. I was 377 almost 4 weeks ago and did a personal WI last night at 348. I rea`lly love this diet, it doesn't seem like much effort.

Everytime I go for my WI there no decrease in lean muscle mass. My coach told me if there ever was that she recommends to eat another packet during the day...she said up to 4 packets if I start losing muscle but that hasn't happened yet. I thought this diet wasn't suppose to do that, maybe i'm confused...

Lean mass and muscle are NOT the same thing. IP does preserve MUSCLE mass, but lean mass is a lot more than just that.

Lean mass is EVERYTHING that is not fat in your body, including connective tissue. When you lose weight, you also lose all the connective tissue that was needed to hold the fat in place - that is part of lean mass.

I should also add that no matter how accurate people believe those scales to be that "measure" lean mass - they are truly a poor measure of actual lean mass. Your doctor can actually get a more accurate measurement using calipers than those scales can offer. Just something to remember when your coach puts too much stock in those numbers.

I guess I am a little confused as well. Lisa and scorbett explanation makes sense, but I had a loss in lean mass as well this week and my coach was concerned. Asked if I had all protein...yes. Said we will need to monitor as it shouldn't keep happening.
