When you have over 100 pounds to lose the enormity (Ha!ha!) of the amount just make goal seem so far away.
I'm not losing that fast (24 pounds in 23 weeks) and I keep reading about people losing faster and I get so annoyed at myself that its not flying off. I'm eating well and finding keeping to 1500 or less calories pretty easy. I'm exercising 2-3 times a week and have just walked into a gym of my own accord, which is AMAZING for me, and will be making an appointment for an induction (I'm writing that to make me do it!).
My pattern at the moment thanks to lovely TOM is that the first 2 weeks of the month I lose a pound a week then the last 2 I go up by those two pounds. When I finally do finish TOM I lose 4-5 pounds. That day is fab but the two weeks leading up to it..which are mostly PMS days are driving me loopy. I want it all regular and sorted - a pound a week like clockwork. Obviously I am delusional!
I think the thing is that I want, and I KNOW this is ridiculous, for my life at the moment to be some sort of musical montage where I sweat a bit, eat a smaller meal then whay hey am at my goal weight. Basically I want it all and I want it now.
That's one side of me..the other is glad its going slowly because it gives me time to adjust and, hopefully, really settle in to new patterns. I dont have any desire to go back to my previous lifestyle.
Today I'm struggling with balancing those two sides..lets say they are my angel and my devil. My devil says it should be easier and faster, my angel says its better to take your time.
So I'm posting for two reasons...
1) Tell me its not just me dreaming of the movie musical montage.
2) How do you keep going cheerfully? (I'm not going to stop or give up but I don't want to feel so bloody frustrated with it. I want to enjoy it again. Its much easier when the pounds are flying off in the beginning)

Try measuring yourself if you don't already. Sometimes the inches fly off faster than the number goes down

I've been known to have the odd tantrum on occasion....
I still have 50ish pounds to drop to get me to where I want to be, but now it's less about that "ideal weight" than how I feel. I keep going because every healthy choice I make makes me feel good mentally and physically, and the cumulative effect of those choices leads to a reduction in my size.

My weight loss has slowed down since I stopped obsessively counting calories, and I'm actually okay with that right now. I make healthy food choices the majority of the time, get out walking most days, and do strength exercises a couple of times a week. This is something I can keep up for the rest of my life, Atkins (or any other highly restrictive plan) is not. YMMV.
