Meatzrus, I'm glad you accepted my post and agreed with my statements. I felt they were inappropriate after posting them b/c I thought they would be viewed as me not providing support, which is what this forum is about; However, after further consideration, I think my post would have been OK, because I was trying to help you by giving you the proverbial kick in the #$%.
Anyway. I personally think that you should stop trying to go for the grass-fed stuff ALL of the time. I do not think that you should fear supermarket meat - AT ALL! I eat supermarket meat ALL THE TIME and I am completely carnivorous. IMO, supermarket meat is not harmful like many promote it to be. Grass-fed is great, when you can afford it,
comfortably, but you have to get over your brainwashing that supermarket meat is bad - it's fine for you to eat, IN LARGE QUANTITIES!
I'm not a Christian, but I think
this page is interesting - myths, lies, and distortions about beef ... Take at look at it and see what I'm talking about.
Lastly, don't worry about your portion sizes so much. Eat until you are full and content! Don't over obsess about how many eggs your eating or how many ounces of seafood your eating. Eat until you are pleasantly full (not gorged, of course) and you don't feel hungry or deprived any longer. I would try to stick to 3 meals a day and just find the plan and routine that works best for you. 500 - 700 calories a day is NOT ACCEPTABLE for a growing teenager such as yourself. You should be eating like at least 2000 calories a day, if not more. It eating more means having to purchase supermarket meat, so bet it, what is the big deal? MEAT IS GOOD. FATTY MEAT IS BETTER!
Don't go hungry!
Oh, and truly lastly, don't you have a freezer? You don't have to go to the market/grocery store every day or so. When you go, buy lots of meat! Usually the fattier the cut, the cheaper, so buy lots of fatty meats and load up your freezer with some and enough to last you a few days in the fridge. Then, as you pull some out of the fridge, pull some down from the freezer to make sure it has plenty of time to defrost (usually 1 1/2 days or 2) This way you won't have to make so many exhausting trips to the market. It's no wonder you're struggling with this. You've gotta incorporate some simple conveniences into this change, and going to the grocery every few days is for the birds.
Koch and Waywardsis have great points as well. Hope things improve for you soon! Good luck.
