I just want to preface this post by saying that I've been around these forums for a while and have always found them helpful. I never thought I'd post something like this and I feel kind of embarrassed about it but I'm hoping that there are people who have had a similar issue and can maybe give me advice.
I started MFP in June 2015 at 139 pounds; I'm 5'3", 34 years old. I lost 20 pounds within the first 2.5 months and eventually got down to 107ish by July 2016. Since then it's been up and down; whenever my weight gets that low I end up rebounding to 115. The worst time was when I hit 125 in December 2017. Sidenote that there is nothing wrong with being 125 pounds, it's just not the right weight for me. I used to do IF a few years ago and just really didn't see the benefits, eventually lost my period, then ended up being super hungry all the time and gaining back some weight. It took like a year to bounce back from that.
This leads me to now. I got down to 108 pounds around a month ago and then my period was late but eventually came and only lasted a few days. Also there is zero chance of pregnancy in case anyone thinks to ask. Since then I've been battling excessive hunger. I've stopped trying to fight it and just let my body do its thing; some days I eat more and some I eat less. I figure that maybe the very low end of the BMI range isn't my happy place. I wasn't trying to lose weight either as my goal is maintenance it just seems to happen as I lose my appetite due to work stress, etc. I've stopped weighing in daily because post binge weights exacerbate my anxiety and guilt. I've stopped tracking food for the same reasons as I was becoming obsessive. I felt like I just needed to hit reset.
At first I felt better but now I feel like it's getting worse. Today was the worst of all as I've just finished eating ~1500 calories on top of what had to be a minimum of 2500 for the day already. I also feel zero discomfort or fullness and like I could even eat more food.
To give more background, I'm pretty active. I workout 45 minutes to an hour six days per week. I do resistance training four times per week and do straight cardio two times per week. My heart rate is high during resistance training; I'm not doing super heavy low rep sets with breaks. I also usually get 12 to 20K steps on my Fitbit with an estimated TDEE that's usually between 2000 and 2500. I'm fairly muscular and lean aside from my stomach these days due to water weight bloat. I've been working out consistently for years and I'm pretty fit.
Thanks if you've read all of this so far. My whole point is I'm not really sure why I feel so desperately hungry. I also get days where I feel too exhausted to do anything beyond my morning workout and shower. That's usually on the weekends. I get around six hours of sleep per night but I try so hard to get more. On the weekends I do get a bit more because my brain isn't thinking about my job. I don't like the feeling of being ravenous even right after eating hundreds of calories. It's concerning and I obviously want to get a handle on it before it gets out of control. I always seem to but I really don't want to gain ten pounds back just to feel too soft and try to cut again. I'm curious if anyone, especially anyone with stats similar to mine, has gone through something similar. I'm wondering if I should actually see a doctor at this point. I'm so confused, upset, and tired of going through this and feeling like I have to fight tooth and nail against myself.
Thanks again if you've read this; I appreciate it.
