The article by N.H. about weight loss was pretty accurate. The only problem is the recommendations. That is, following the US dietary guidelines. I don;t recommend that.
To make a long story short, study up on the “paleo” way of eating and exercise. Six years ago I cured my growing blood sugar problem and lost 30 lbs in 4 months. I’ve maintained that ever since then.
I fear that a lot of “preppers” are fat and out of shape because they eat what they store, that is, they consume lots of wheat and vegetable oils because they store well. For anyone that wants to stay healthy now and after the SHTF, you are better off eliminating these items. And while you’re at it, ditch sugar as well.
Store coconut oil (non-hydrogenated) and coconut milk and ghee for healthy fats, as well as canned salmon and sardines for Omega 3s and protein.
I’ve not had wheat and vegetable oils for six+ years and have outdone members of our military in their mid 20’s during 5 km races. Not bad for 52 years old! – Dave, RN
