I normally allow 3000 calories a day but looking at the chart, I'm well under what I should be taking, but I'm never hungry or craving food, I just get thinner.

A male youth exercising heavily can easily burn 3000 calories in a day. I lose just under a kg a week at 3000 calories/day when doing a hard bushwalk.

So in a couple of years you'd disappear altogether?
Orion wrote:Most people lose weight while bushwalking. As long as you're only out for a week or two it probably won't matter and in fact most people are really happy to come home skinnier. But if you kept up that level of activity you'd eventually be forced to start eating more. I usually budget about 3500 Calories per day. On strenuous trips with a very large pack I eat more. On easier trips I get by with less. 1600-2000 Calories is less that what I eat at home most of the time.
By the way, it's Calories with a capital C. Lower case calorie is 1000 times smaller. I know that's silly and confusing but that's how it is.
1 Calorie = 1000 calories = 1 kcal = 4.184 kJ

According to these sites with the wt I'm carrying, speed etc I burnt 4500 - 6000 calories just for the walking part. Add what you burn the rest of the day and there is no way I can carry enough food to replace what I burnt roughly 5500 - 7000 calories a day. With a 29 day walk at the end of the year food is fast becoming my bugbear. I have worked my daily food up to 3500 - 4000 cal/day on average, with a good balanced meal plan. With 1 kilogram = 7700 calories I'd be loosing a couple of kilograms a week at least. Do these figures make sense? Looked at the calorie/ounce chart and unless you have a diet of oily/sugary food you just can't eat that much. Maybe I will just have to plan more caches so I can carry more food, I was planning one every 6-7 days.

Thank you for the value.
I like the foods that are over 20 kj/g and one of them, that I like the most, is the Brazil nut, weighing in at 28 kj/g.
