  • Calorie Restriction for Longevity

    I'm kinda new to Primal, and I read that IF can lead to longevity due to calorie restriction. I'm unsure of my exact BMR, but I know that I'm likely underweight, so I don't think I could calorie restrict anymore without negative effects. What should I do? Would it help if I did IF and ate enough for maintenance, or would that just defeat the purpose of doing it for longevity?

    I think the idea of calorie restriction for longevity is misled. Restricting specific things, like methionine, can lengthen the lifespan without requiring a restriction of total calories. Of course, restricting total calories also restricts methionine, but it restricts everything else, which may be unnecessary.
    My opinions and some justification

      Intermittent fasting works in the same manner. I like to eat at around my maintenance or a smidge above.

        Do the IF but eat more nutritious calorie dense foods than what you are eating now. Benefit of IF is supposed to be letting the body do its maintenance chores without constantly having to deal with incoming food. Could benefit you and help you be at the correct weight.

            Alright, so I found out gelatin is low in it and high in protein. I know it's not as good to have the cheaper, more processed kind like jell-o, but for my purposes of avoiding methionine, can I get away with it? I can't really afford grass-fed gelatin at the moment

              I would imagine that regular gelatin is okay. You can also buy gelatinous cuts of meat and slow-cook them.

                Hmm, slow cooking isn't really an option right now. I live under my parents, so I can't even eat full on paleo, I just try to suggest to my parents to buy somewhat healthier, but they get what they can afford. Is getting it from Wal-mart alright?

                  Do the best you can with what you have to work with. Walmart knox gelatin will work fine for now. If you helped out by clipping coupons or something would your parents let you have a few items? You can get coupons for about anything now a days.

                    The point behind grass fed food products is to get a more favorable omega 3 to omega 6 ratio in meat products with fat! Gelatin is zero fat and pure protein so you get no extra health benefits from eating grass fed gelatin to my knowlegde...

                      those little packets of jello or knox gelatin in the store will cost waaaaaaaaaaaaaaaaaay more per portion than a canister of good stuff off the internetz.

                      eta: just checked my canister of great lakes and it has 62 - 1 tablespoon servings. i paid around $12-$13 from amazon.

                      As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.
