Surprising Weight Gain after Running!

Hi pic3a, yep the carb craving stinks! It's important to keep your protein levels up at each meal You need to calculate it according to your weight on google or somewhere that is reliable. The US RDA is off we need more protein than the gov't suggests.
I've run for over twelve years and the month or two before a 26.2 marathon, I'll see a drop of up to five pounds due to the high mileage the last month and a half of training. At that point, I've never been able to eat enough to stay the regular weight I was, so I never minded it.
Salty foods also create a temporary gain and if you're drinking lots of sports drink, you might be picking up salt in it. I've known ultra marathon runners and they all take salt pills with them on runs of 20 miles or more, even on hot days of 15 miles, but the salt will retain water and the scale will show it.
So, my advice, eat more protein and remember salt is important-just not too much of it.

You have a weight range, right? My weight often goes up a few pounds and back down but I don't allow myself to freak out because I give myself that range of 3-4 pounds.

I run a lot and experience the same things. Have not figured out the short term weight gain, but it seems to trend back down in a few days. As for the hunger, I am hungry all the time. I take this as a clue from my body that my workout took all the stored fuel I had, so feed me! I also think about food like the air we breathe. Have to have it. Good luck on your 13.1.

I'm iron man training and have gained almost 15 pds.
Like you I'm picking at foods that I didn't before. And either I rationalize it out that I deserve it or I'll work it off later or I get a lot of calories that day.. Or my body needs the carbs and I'm not getting them enough through better food choices..I'm not sure.
I'm trying to grasp it. I mean who the F gains weight ironman training?
Make sure your staying hydrated

I've been running a lot in the last 2 years - 6 or more days a week, and sometimes even longer streaks. I've done 10 half marathons and I have my first full marathon at the end of May. This is what I learned:

1. While I was still losing weight, I was not eating "classic" carbs before running... I preferred to be slower and get a bit hungry after 4-5 miles, but still run on my own fat plus lots of veggies/lean meat . IMPORTANT TIP that HELPED me a lot with hunger - I ALWAYS had a protein shake (under 200 cals, but 25-30 grams of protein) after every single run over 3 miles! this helped tremendously with hunger...

2. Once I reached my goal weight, I discovered I need to account for the fact that I consume fewer calories running and thus eat fewer calories back - when I started running I considered I burn about 100 cals per mile (and thus ate back 100*no. of miles run), after losing 60+ lb I consider I burn only about 80 per mile (so I have less to eat back)

3. No matter how much I run, I still need to count calories and measure my servings in order to stay within a 5lb range... "funny" how I always move up in that range, but never below my goal weight...

4. I only started using gels for runs over 8 miles... for 8-10 miles I use one gel in the middle of the run; for 12-17 I use about 3; I only used 4 gels for 18-22 miles; I do drink a recovery drink after my runs now (80-100 cals)- I started needing it when I started marathon training

5. While I was losing weight, I would have mostly protein with every single meal... And veggies. Almost no bread/rice/pasta. I was running in the afternoon, after lunch and a light snack like fruit or cottage cheese. I then the protein shake right after running and dinner within 1-2 h.

6. I can lose weight and train very well while preparing for a half. I only experienced the incredible hunger about 10 weeks into marathon training... My muscles simply needed more carbs to not hurt...

I now finished the highest mileage runs in my training cycle, and I started focusing on losing the 3-4 consistent (aka over my allowed range) pounds I gained with Marathon training... I am focusing on lost of protein - whey, lentils, chicken breast, Greek yogurt, veggies or fruit with every meal, as little sweets and nuts as possible, desserts focused on fruit.

Good luck and don't stop running!!!

I'm iron man training and have gained almost 15 pds.

This happened to me when I was training for an Ironman too. I justified it with the classic "I'm doing sooooo much training I must be able to eat whatever I like".

NOT TRUE (for me anyway) :-(

I'm now training for a half Ironman (my favourite distance), and I am keeping a very tight control on my food, logging everything. I am still losing (and will continue to do so until I reach my race weight). The key for me was rethinking my "entitlement" attitude to food whilst training and starting to concentrate hard on using food as fuel rather than as a reward\reaction to a hard session. I find this quite difficult because some days I am absolutely ravenous, but I know I have myself set up in such a way that I plan exactly how much food I will have\need and I don't go over that amount (however much I want to!).

Yep, same thing is happening to me! Thankful I am not alone but also sad that we are gaining unwanted weight.:grumble:
