I don't usually eat in the field during hunting times maybe altoids breath mints, I do bring plenty of water, but I do like a big breakfast before heading in the field for a days hunt, I own a small RV a Toyota Sunraider it sleeps four and has everything I need when I get back from the morning hunt, its really nice after hunting all day just to come back eat and relax before hitting the sack, not having to drive anywhere. I believe when it comes to good nutrition, moderation of fat and salt intake is important, and good regiment of exercise keeps the plumbing clear. I workout five days a week to keep in shape been doing it all my life. I don't believe in low carb diets, they are dangerous, your body needs a certain amount of protean and carbs for your body to function right, low carb means low energy, thats were your energy comes from is your carbs, makes suger for your body, if you need to trim down in size/weight decrease the amount your eating, much better for your body than starving it of carbs, just my opinion being a health freak all my life, if people would exercise more, and just eat three square meals a day, and try not to eat too much junk food, would be better off.
