Hi! I just turned 20 and am in college, so I'm not that much older than you. That's great that your family is supportive of you eating meat from animals that have been responsibly raised. You said that in a two week period you only get meat once or twice. Is it because your family does not buy meat that often? Or is it because the grass-fed/pasture raised meat is too expensive for your family? If your family is hesitant about regularly buying grass-fed meat due to the higher costs, I can completely understand that. As a college student, I can't afford regularly eating this type of meat. Also, my family can not afford to regularly eat this type of meat as well. However, there are some money savings tips you should know when buying grass fed meat. First of all, I would never buy this meat in a store. Never. It is WAY to expensive in most stores. Instead, it is much better to buy it directly from a farm. Also, consider eating organ meets. They really aren't that weird. Grass-fed organ meats are about as expensive as regular ground beef. If you asked your parents to just buy you some pasture raised chicken hearts, it wouldn't be NEARLY as expensive as buying pasture raised chicken thighs or drumsticks
Also, it might be hard if you are the only one eating Primal in your family, but you can do it. Just tell them you are trying to eat more unprocessed and unpackaged foods They might not understand you if you say "I'm not eating any wheat or grains every again" but if you say "I'm incorporating more whole foods such as: fruits, veggies, and meat", then they will certainly understand Not everyone agrees with cutting out wheat, but almost everyone agrees with eating more whole foods.
One more thing: make sure you don't go too low carb. On this forum, you'll see a lot of people who are doing low carb. Some people(including myself) on this forum are trying to lose weight or get control of their blood sugar and so they(including myself) are focusing more on low carb. Some people also just do better on low carb. You have to know what works for you. Do not do low carb just because someone tells you it is best. Do not do high carb just because someone tells you it is best. Since you are doing sports, since you are not trying to lose weight, and since you are probably still growing, I'd say make sure you get in some really good healthy carbs like sweet potatoes. And do not be scared of fat. And make sure you eat tons of veggies!
