low energy for running @ week 20

I started running in febuary and worked my way up to 30 mins of running untill at about 6 weeks when I hit a wall and couldn't run 5 min. I started eating a kashi bar before my early morning runs and took a few days off and worked my way back to a 38 min 5km 3 days per week. Now I've hit another wall and it's the same thing all over again. Any suggestions as to why this is happening? I eat  a kashi bar and a slice or two of bread eat day so I'm getting carbs, I'm probably only at 40g protein so i know i could increase here also. Just wondering if this is normal, the lack of energy. Does it come in cycles? I try to get 60 min exercise a day and run evey other day. I have a 10k planned for June 18 and afraid I won;t be able to do it. :(

As you drop the weight quickly it can really zap your energy.  One week I lost 10 pounds...I could hardly move.  The energy level does come back...But sometime you will hit the wall.  A few ideas on no special order.  Up your protein.  Find a good whey protein shake (you can stomach or bougie) and add it to your diet.  Add some potassium to your diet; spinash, oranges, bananas, broccoli, yogurt.  Add a small amount of salt to your diet too...Don't go hog wild, just alittle.  Brian  PS  Know the signs of dehydration...# 1 reason WLS people reenter the hospital...Eyes wide open as you exercise, especially in the summer...

As I increased my workouts, my surgeon was adamant that I needed more protein. 40 g is less than what is recommended for normies. Anyone who is losing weight rapidly should be getting 70-90 g minimum IMO and IME.

With 60 minutes of cardio a day you need 2 or 3 times that amount of protein. Also when you are at a big calorie defecit it very normal to hit walls. I would just do what you can in the weightloss stage and shoot for performance when your calorie defecit shrinks.

Thanks everyone! I'm sipping my myoplex as I type this. I'm going to work hard on getting more protein in and try weight training on the alturnate days I don't run instead of walking 5k. It's so easy to forget I'm sleeved and getting less calories protein etc. I eat whatever I want in small quanities so it's become my new norm and I forget it can also have it's limitations.  I really appreciate the feedback!!! Will save the 10k for the fall. I can still work on my 5k time, would like to get to a 6 min/km when my energy returns.


Just one more thing..I can't believe this is my life!! I'm dare i say athletic now!? Lovin the sleeve!

You should really stick to the weight training and protein while you lose. That's a huge part of regain for most people. As you loose weight it's a mix of muscle and fat and you need to hang on to every oz of muscle you can. The more muscle you have the higher you metabolism runs.

Low energy can come from a lot of different sources. When is the last time you had labs done. Low iron, potassium and B can all cause low energy. Look for carbs that are better. Breads don't do much for generating energy. Oats, flax seed, and whole wheats are the better carbs. You need to experiment with everything. Even fooling your body with a different set of exercises can spike your energy. Good luck and don't give up. A 10k is very doable in July with some positive attitude.
