Is it possible to 'top out' on cardio strength?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Asked by Nick E., Menomonie, Wisconsin

I'm 23 years old and a fairly active person who has been in training as an amateur boxer for some time now, and I'm trying to improve my cardiovascular strength and stamina. I've been running outdoors quite regularly (every day to every other day), but I seem to have "topped out" my cardio strength. I was wondering if there is a more effective way to further improve on this. Is it better to run longer distances but at less intensity or vice versa? Do you have any other recommendations?

Can you explain Vitamin Water to me?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Asked by Becca from California

I was wondering what the professional opinion on Vitamin Water is. How can it be zero calorie when it has over 5g of carbohydrate per serving? Also, should I be concerned about vitamin toxicity? I know most of them are water soluble, but could I accidentally be consuming a dangerous amount of things like vitamin C?

Should I give protein shakes to my 8-year-old daughter?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Asked by Michelle, Kentucky

My 8-year-old daughter is about to begin the "Girls on the Run" program (a program where they train girls between third and eighth grade to run a 5K,) at her school. She would like me to make her the same protein shake after practices that I have myself after my workouts. (I make an 8-oz smoothie of skim milk, fat free vanilla yogurt and vanilla flavored natural whey protein powder. I do a combo of yoga, pilates and strength training.) I am not sure if this is something she needs or should have, nutritionally. Any advice or alternatives for her after her practices? She is convinced she needs something more than water because she does experience muscle cramps and has had shin splints before. FULL POST

How can I eat healthy if I have to buy in bulk?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Asked by Nate, Yellowstone National Park

I live in a very remote location: Old Faithful in Yellowstone National Park. I have a hard time buying groceries that are healthy. There is no way I could get to the store even once a week. I end up buying in bulk: frozen (limited space), cans, dry just-add-water type stuff. Any suggestions for better eating?

How can I lose weight if I have hypothyroidism?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

How can I lose weight when I have hypothyroidism and I can't do strenuous exercise? My doctor is still adjusting my thyroid medication, so my TSH (thyroid-stimulating hormone) is still high at 22. Added to that, I've got heart problems and have been told by my cardiologist not to do strenuous exercise! I do a lot of walking and typically do 10,000 steps a day. I've been doing a low fat 1,400 calorie diet with no result. I was thinking about a low-carb 1,200 calorie diet and upping my steps to 15,000 a day but I'm wondering what else I can do when I can't exert myself.

How can I stop being hungry?

Every weekday, a CNNHealth expert doctor answers a viewer question. On Friday, it's Dr. Melina Jampolis, a physician nutrition specialist.

Asked by Jeff of El Centro, California

Losing weight has always been tough for me. It's even tougher for me now that I'm in my 40s. However, I made a resolution for 2010, and with diet and exercise, I've managed to lose 35 pounds.

I've managed to lose weight through grit and determination. The problem is, I am always hungry and my appetite is ravenous, difficult to satisfy. I want to eat until I'm full EVERY TIME I eat. If it wasn't for force of will, I would continue to eat and pack the pounds back on.

Is there anything I can do to fight the hunger? I try to snack on things that are healthy, but it seems no matter what I snack on, I get penalized with putting weight back on. I worry that if the only thing I have going for me is grit and determination, that might not be enough to stay in the fight. FULL POST
