There seem to be some misconceptions, when it comes to low-carb food.
Any form of bread is a no go. This includes crackers, crisp bread, whatever contains grains or sugars. That includes fruits as well! Maybe one a day, but preferably no more. Sausage or processed meats/meals usually contain high amounts of grain (as a filler) or sugars (flavour enhancers). If you want to bring them, make sure they contain a lot of meat and/or fat. Stay away from anything that has less than 85% meat.
Since low carb often is comprised of whole foods (no processing at all) you might need some additional salt or minerals, especially when active. A small bag of rough sea salt in your pack is a good idea.
Eggs keep well for longer periods of time, even in hot weather. As long as the yolk doesn't touch the shell they should keep. When in doubt, put them in water. when they sink ok, when they float... check.
Dried sounds ok, but how about nutritional values?? And fat is your main source of energy. Lard should be good, since butter and pig's fat might go rancid in warmer conditions. Hard vegetables keep rather well too. For an occasional energy or moral boost; dark chocolate up from 70%. The higher the better.
Correct.
As a person with 6 years of medical uni training I would like to add that the carbo hydrate obsession of today is all based on wrong ideas and info.
The cells are fuelled ( Krebs Cycle) by Guanocine Tri Phosphate which is basically split up fats, carbohydrates and proteins.
A mixture of those should be ingested.
A wrong balance is unhealthy. One extreme of the low carb diet is Atkins Diet. You not only lose weight, but can cause irreversible damage to your kidneys.
Having said that, we should all eat less sugar, be it in form of Caster Sugar, or sugar in fruit and veg. There is absolutely no difference between processed sucrose and naturally occurring sucrose.
Juicing? Full of sugar.
Gentlemen, everything in moderation!
Edit: Simplified and short: Complex carbohydrates ( like in pasta, bread) are split into simpler carbohydrates (=sugars) starting in the mouth, then stomach and then the thin intestine.
Those simpler CH are absorbed and further "worked on" until fit to be used in the cells.
Low carb diet is based on some very funky "science" .
