Exercise and losing weight-need your knowledge!

 I posted this under MacMadame's post with the nutrition article but thought I would put it here also to see what information/help I can get.

Thanks in advance everyone!

Thanks for the article Macmadame.

I am really confused right now, though.  Maybe you can help me out.  I am still losing weight- I have about 40 to 50 lbs. left to lose.  I started walking way back last August and did that for a few months but then I got bored so I started a C25K in late October.  I have walked/run since then with breaks for a couple of weeks over christmas and then again at the end of January due to a surgery.  I am back walking/running again (I do 3 miles approx 4-5/week, run about 3/4 or a little more of that) but am so confused on what and how much I need to be eating.
Since I am still trying to lose I feel like I should be sticking to my protein/low carb plan. But with only eating a few ounces of protein at a time 3 to 4 times a day, sometimes it doesn't seem like enough fuel for the exercise. I sometimes get light-headed throughout the day (not too bad) and feel pretty exhausted at night.  And even with doing that much exercise, I am losing extremely slowly if at all and feel like maybe I am not eating enough?  
I generally have between 700-950 calories/day, about 20-30 carbs, 60-80 grams of protein.  I have been trying to add back in a protein shake for extra protein when I think of it.  I don't really get hungry, so it feels like I am always trying to add food.
On one hand I feel like I should be sticking to my "weight-loss/surgery" rules and do protein first, lo carb, but on the other hand everything that I read about running says that our bodies need carbohydrates for fuel.  UGH!
Maybe that's why I'm not losing very much-my body is holding on to what it can?

I'm not sure if this issue has been addressed repeatedly. I usually stick to the VSG forum, but started looking around a bit for information/knowledge!  I only looked back 5-6 days in post also.

I might also try posting this as its own thread to see what people think.

Thanks for any information or insight!

Here's what I did the first year:

Notice how my exercise time went up, my calories and carbs did go up. But not drastically.

You need to eat enough to have the energy to do your daily activities. But no more than that. You've got 40-50 pounds of fat to burn for energy so you don't need to get it all from food.

What I did was eat most of my carbs around my workouts so I wasn't going nuts with the carbs but I was ingesting them when my body most needed them rather than spreading them out during the day.

I think you need more calories but not more carbs. I'm no expert but I do know when you still have a good amount to lose you don't need to carb up. Your body can turn excess fat or muscle into glycogen and use that as a carbohydrate. Protein and amino acids are the most important thing you can do to help the body hang on to as much muscle as possible while losing. Until you are at the point of working out for performance not weightloss I would keep the carbs low. Anytime you are at a calorie defecit you will be tired and struggle through workouts, that's just part of it. I would add a protein shake and maybe some good fats but not many carbs. Like I said I'm not an expert so anyone who differs can feel free to call me out on it, this is just my opinion.

I had the exact problem a couple of weeks ago.  I had problems pushing myself to go faster and longer.  If I did push I would get sick and get a headache.  All I did was add a little snack 30-45 minutes before my workout and bingo..it worked.  I work with a girl that used to be in track in college.  She told me that I needed to have a snack high in protein with some healthy fat and some complex carbs too.  So she told me to eat 3 apple slices with peanut butter.  I told her I was worried about adding calories into my diet.  I want to lose weight not gain.  She told me...she actually said she swears by the bible it will work.  You know what it did!!  I lost 3 lbs this week.  I was at a plateau and the extra food helped my endurance and I was able to exercise harder.  I also make sure I drink enough water.  I drink about 32 oz in about 90 minutes.  For some that's too much but it's perfect for me. 

Thanks so much for the information everyone. I think I will try adding some protein before my exercise in the morning and then try to get in a protein shake on the days that I exercise.

I really appreciate all the feedback. If anyone has any more suggestions I am all ears!
