Extra Weight
Extra Weight
I've done a lot to reduce my pack weight, but I think that it's the extra 20 pounds of body fat that I'm carrying that is slowing me down at this point. Has anyone lost weight and noticed that backpacking and hiking is easier?

Absolutely. I gained about 15 before the precious few trips I made last year. It was the first season I was out of shape, and it killed me. I noticed that for some reason the altitude affected me quite a bit more than normal as well. Now I'm back down close to my normal weight again, and I have to wait until next year before I can let you know if it helped!

Well, I'm working on getting some of the weight off - trying to go back to cooking instead of eating just snack and fastfood. Almost one week into healthy dinners and I'm already starting to feel a little bit better.
I knew I wasn't eating real healthy food, but when my son complained this past week that we never have any healthy food in the house I gave it a little more thought. He's 20 - I probably should have told him to go buy some healthy food, but I remember being a starving college student.

Altitude has always been a problem for me. I can't remember the time when I didn't get AMS on a multi-day trip. I have a doctor who is really interested in helping me overcome the problem. One of the first things I asked about was shedding a bit of excess insulation around my middle. He said it will make a difference. I joined the 10,000 step per day plan and have already seen some positive results. I walked 5.56 miles this morning with an average speed of 3.9 MPH. My pedometer reads 16,646 steps right now. I'm feeling better, losing weight and am optimistic about spending more time in the back country this year.

Yep! In fact I have a fresh prescription in the medicine cabinet right now. Unfortunately it doesn't seem to do the job for me that it does for others. I've tried almost everything I can think of to avoid AMS. The only thing left is to pack lighter --- both on my back and on my body. If that doesn't work I guess I'll have to stick to the lower elevation trails.JM21760 wrote:Old G, has your Doc mentioned Acetazolamide, AKA "Diamox" as a deterrent for AMS? Just Curious.

It's been nine months so hopefully you'll see this, but I learned a couple years ago from my doctor that hydration was the key to altitude sickness. He is an avid backpacker and fisherman so I just thought to ask because I used to always get major headaches the first and sometimes second day at altitude. Now, I drink a gallon of water a day for 30 days before a trip and superhydrate my cells. I haven't had a problem since. My first trip was Mt Whitney in a day from the trailhead. I never once had a headache. Now I must say, I also pop a couple ibuprofen the first couple days as well just in case. I use this practice religiously now. I remember also reading about hydration in one of Jardins books. I hope this helps.

Many thanks for the response. I am a firm believer in proper hydration. I carry a hydration bladder in my pack and sip from it almost constantly. A fellow backpacker once told me, "Drink, walk, pee. Repeat." That's my motto now.tory8411 wrote:Bill

I find it very interesting that what works for one person may not work for another. I've read everything I can find on the subject of AMS and tried every suggestion. I guess my body is just unique. :-)

AMS has a heavy genetic component that is not going to be overcome no matter what precautions you take other than meds such as Diamox, and if that doesn't work, you're out of luck. For instance, they have taken those of Tibetan ancestry who were born and raised in lowlands, taken them up to altitude, and they still have an advantage irrespective of any other factor. It has to do with the transport and utilization of oxygen in their blood. Those for whom hydration works were probably dehydrated to start. So really, that leaves proper acclimatization.
Interestingly, those with a higher aerobic fitness level will show a greater percentage decrease in their ability to work at altitude than someone with a lower aerobic fitness level (VO2 Max). This means that aerobic fitness has nothing to do with whether you get AMS or not (sorry, your doctor was wrong on that one.) Also, those with a higher muscle mass in the working muscles, which in this case would be the legs and hips, will also be more affected; this has to do with diffusionary distance of the oxygen to the working muscles. The loss of any weight, particularly fat weight, means there is less of you to move, and therefore less work your body has to do, ergo the physiques of distance runners.
That being said, there are a couple of things you can do to improve your performance. While a high carbohydrate diet has not been shown to decrease incidence of AMS, carbohydrates are more efficiently burned at altitude than protein or fats, since it takes less oxygen to burn carbs than it does the other two, particularly fat. The use of such foods as trail mix high in nuts and seeds is actually counterproductive to performance, as such foods not only take a longer amount of time to be digested, they require more oxygen to burn; therefore they are a poor choice for on-the-go snacking. Same goes for beef jerky and the like, which also utilize more water to metabolize. High storage of carbs in the muscle in the form of glycogen will also bind water; this is a much more effective way of hydration than trying to drink a gallon of water a few hours before a hike, since there is no evidence that this water will be stored; in other words, prehydration is of limited use, at best. This should improve your work ability at altitude, even if it doesn't alleviate AMS, and any little bit helps.
