How many Calories do you need ( article by Ken)

[Prepper1]

I think that's why the old stodgy puddings were made years ago, which I still adore, made with suet "n" stuff, high calorie belly fillers.
I think from other survival type programs I've seen, anything other than light foraging from readily available foods. i.e. at your feet, rapidly consumes calories.
One of the best tips I saw was to have a little extra weight on your body to see you through the period from shtf to finding a source of foods, obviously in conjunction with your stored food supply and to put vitamin supplements in your food stores.
You can buy a years supply of multivitamins on eBay for about a tenner because under stress your immune system is weakened so bumping it up with vitamin d3 supplements (5000 I.U.) and a daily multivitamin will help greatly, just make sure you've got enough for your whole group.
Something I found out ages ago was that if your a ginger like me, your body has trouble synthesizing vitamin d3 (5000 I.U.) from the sun, so to take vitamin d3 supplements.(5000 I.U.)
I tried it because I had general bad joint aches and pains and within a couple of months they were gone and I've never felt better.
The d3 supplement I take I bought from E bay its a u.s. product ( healthy origins 360 soft gel caps) and they recommend a minimum daily dose of 5000I.u. before I tried the U.S. recommended dosage I tried the U.K. recommended dosage which had little or no effect.
Apparently vitamin d3 helps the body synthesize and absorb calcium, which is probably the reason I used to crave milk, I used to drink gallons of the stuff and the reason for the joint pain must have been a lack of calcium, which the d3 has sorted out.
