New here - trying to figure out why I'm not losing!

well a lot of it has to do with your diet. what are your meals like?

An hour on the treadmill... what pace, what incline? An hour walking, vs an hour running at a steep incline are very different hours!

Make sure you're challenging your muscles and not doing the same old thing. It may be time to kick it up a notch!

Stress can cause your body to release the hormone cortisol, which tells your body to hold onto fat. If you think you may be either A. overtraining or B. stressed from your personal life, then the answer is the same......get adequate rest. Nap, go to bed early, meditation, or a week off from the gym may be what you need to get back on track. Not sure if this applies to you, but you did mention that you dislike your work situation right now. I hope this helps!

So refreshing to hear this. I'm in the exact same boat. I'm 5'3", and before I began training for a half marathon in May, I was between 115-118. After completing the half marathon I was 130. I always gain some weight while training, but this was a lot even for me. After recovering from the half, I got serious about weight loss, got back on MFP, and began sticking to a strict 1200 calories a day. After a week, I had gained a pound! None of my clothes fit anymore either. It's very discouraging because I feel like I can't wear anything, but I also don't want to buy bigger clothes because it feels like accepting this new weight as permanent.

I can't offer anything other than my personal experience, but here goes:
- Long endurance like training (ie running for hours) has never helped me lose weight. It's great for your heart and lungs, but for me, the scale never moves. I have been trying interval training where I do high intensity cardio (elliptical, bike or treadmill) with brief cool down periods for 35 minutes 3 days a week. I do yoga/pilates and strength training twice a week, and once a week I go for a longer 4-8 mile run to keep my endurance up. I'm aiming to follow this plan for three weeks followed by one week of longer, lower intensity (45-60 minutes cardio at a "conversational pace") workouts just to switch things up. Remember too that when starting a new workout regimen, it's normal to gain a couple pounds at first as your muscles adjust. This should come off in a few weeks.
- As for diet, and I know this one is controversial, again it's just my opinion, I stick to 1200 calories a day (sometimes I'll throw in 1000 calorie days to mix things up) and don't eat back my exercise calories. I know some people firmly believe you should, and maybe that works for you, but from past experience, eating back those calories has never helped me lose. If I have an event or something and go over, I don't freak out, but I really try to stick to 1200 calories.
- When dieting, I cut out all refined and added sugars and most non-fruit carbs. Don't know why, but grain based carbs just make me hungrier. In maintenance, I will have some sugar now and then and some whole grains. I drink tons and tons of water and keep my sodium in check to try to keep from retaining.

I hope this helps a bit. I know how discouraging not fitting into your clothes is, but I've gained this weight and taken it off before, and I know you can do it!

Alright, so given that you already seem to be following my earlier advice (and I was certainly hoping you were!)... I'm just a bit shorter than you and have never really been able to maintain your "normal" weight, but I spent most of the last 20 years around 125. After slowly working my way towards 140, it was time to get my butt back into gear. Literally.

While starting a running routine has been good, what has really helped me the most over the past 7 months was really watching my carbs. I started on a strict low carb diet and lost a relatively quick 10 pounds then plateaued. My gallbladder came out in Dec, so eating that way was actually causing me some issues, so I went super low fat/high carb (as recommended for those with no gallbladder) and not only didn't lose a single pound between April and August, but gained a few back. I bounced around between 129 and 131 all during that time all while increasing my run lengths and speed. Frustrating, to say the least. At that point, I decided to start watching my carbs again, but this time I didn't cut them back as far. I'm eating somewhere under 80 grams net each day, some days a lot less, some days a few more and mostly focused on just cutting out sugar, processed wheat, white rice, etc. I've steadily lost another 7 pounds since then and I feel pretty darn good. You might give something like this a try and see if it doesn't help you, too.

ETA: My calorie goal stayed relatively the same during the whole process: 1250 per day.

I don't know if this is true or not, but I was told that if you eat 1,200 calories a day, you'll weigh about 120 lbs. So if you're eating 1,500 calories a day, you're going to weigh close to 150 lbs. So, maybe just adjusting your diet to no more than 1,200 calories. And try adding a little protein to your breakfast...put an egg on that English muffin. it'll make you feel fuller longer. And I agree, sometimes too much exercise can make you weigh more. It makes you hungier. I never lost weight exercising that much. Like I said, I lost my weight it by merely walking everyday and lifting weights a few times a week. I think diet is more important when it comes to weight loss. Good luck and I hope you get back into all those clothes....we're all routing for you!
