100lbs lost and STUCK!

I haven't lost quite that much (I'm on my way!) but I would try a different workout. Do you have any DVDs you could try? A cheat day may be in order too, just to jumpstart your metabolism.

I agree, if you're walking or jogging every single day, your body has gotten used to the exercise and your metabolism slows. It looks like you're eating enough, but try to avoid going below 1200 calories. I usually eat a minimum of 1300, max 1500 and I exercise to burn 300-700 a day.

You should try a workout DVD or something. If you're used to jogging, run intervals where you run fast for a minute to really get your heartrate up, and then jog or walk for a minute. I've been using some great workout DVDs in the past few months that have kept the weight loss going. I started with the 30 Day Shred ($9 at Walmart or Target), and I moved up to Chalean Extreme and Turbo Fire now (available from Beachbody). They have strength and cardio together so you get a great workout. It just sounds like you need a change to kick start your metabolism again. I highly suggestion intervals training since it's proven to do just that.

Hi! I just had to respond because I am in the same place you are! I have lost just over 100 pounds and am now struggling to even get another ounce OFF! For me, it is both the food and working out. I have become bored with my usual meals and am having difficulty shaking it up for fear that I will have too much sugar or carbs, etc (even though it's healthy ... it's different from what I was eating when I was losing). I am going to try and vary my workout as suggested below. I still have quite a bit to lose and I refuse to give up now!
It is great to know other people are in the same position - thank you for posting. One day at a time, right?
Congratulations on your success!!

2 years ago I went from 250lbs to 130lbs. I found that once I got down to 150 or so it was super hard to lose that last 20lbs and even harder to keep it off. I had to workout SUPER hard everyday and had to strength train like a mad woman. i also had to eat ALL of my excercise calories. It's like the closer you get to your goal the harder your body fights againt you. It sucks!!!!

I've plateaued a few times and it truly is breaks and change that get me out of it. The last one had me really perplexed as it lasted about two and a half months. I had lost 43 lbs to that point. I tried doing small changes in my cardio and strength training. But there seemed to be two things (that I can tell that really pulled me out in a big way--have lost 10 lbs since then in a fairly short time):

1. Calorie accountability in my workout. I was basing how many calories I was burning in my workout on what the machine said. At one point it may have been fairly accurate, but as my efficiency in doing that machine (eliptical, treadmill, stair climber, bike) increased, and my weight decreased, that gap between what the machine was saying and what was really happening was getting wider. Finally, I bought a heart rate monitor that tracked calories based on how hard my heart was working. I was shocked that after my workout I was OVER-stating how many calories I was burning by about 300-350. So, I was eating as much food as I was 20 lbs heavier and burning lots less calories--so basically I was eating at maintenance level.

2. The second thing I really focused on, and this is still a struggle to change, is that I now try to focus more on what my body is telling me about hunger than what MFP (calorie counter) says is okay. Calorie counters are extremely helpful in getting you into the ballpark of where you need to be. But to find that sweet spot of what your body actually needs while losing weight is very much an individual thing. So now, I try really hard to not let external cues determine when and how much I eat. Rather I try to listen to my body. I've noticed there is a space of time between barely satisfied and stomach growling that is my sweet spot and it's actually just a little less than what calorie counters allow me or say is okay. So I try and aim for that.

There's a book I recently read called "Mindless Eating" by Brian Wansink that really helps open your eyes to the external factors or cues we use to know when it's time to eat. Unfortunately, we have become really conditioned to these external cues (what time it is, smells, social settings, etc) and less to what our own bodies tell us. Anyway, it's an excellent read.

So, there's my tips. I am back to losing again (just have another 15-20 lbs to go) and I am doing it more consistently than ever too, which is nice! Best of luck and hang in there--never give up--it's a journey, not a destination!

Sorry, one more suggestion of something I am doing different. Before I was doing 75% cardio, 25% strength training. I was really resistant to doing any more than 25% strength training because you can burn more calories in a cardio workout (thus eat more) than you can in a strength workout. I WAS WRONG!!! I am able to lose just as much doing weights, but not burning quite as many calories. I really think strength training and eating just enough calories to keep the hunger pains away (no more, no less) that really fuel the metabolism throughout the day.

The weight routine I adopted is called MAX-OT (you can Google and read more about it). Basically, you do the opposite of what I was doing before--it's more like 5 minute warm-up (treadmill walking) 35-45 min of weights and 16 min of cardio. The kicker, though, is you have to do it all-out--leave no strength when you are done. For the weights, you work two different muscle groups per day, lifting the heaviest weight you can lift 4-6 reps. When you can do six reps, you do the next biggest weight. I usually do 4-5 rounds of six different types of weights.
