Very good points, we make our own dehydrated meals and also vacuum seal, I used resealable bags this year and they worked well. With todays high calorie per ounce food you can cut substantial weight. 2 years ago I was 2 lbs per day, now I am just over 1 lb a day.
One can’t over emphasize leg, core, and cardio training, it does wonders for the weight your “mind” has to pack each day.
