Less calories means nutrient just have to be denser overall. Nutrient dense food does carry more calories, but I find that I’m more satiated when I’m nutritiously satisfied. A lot of food carries calories with little to no nutrient, it’s easy to overeat on those foods and still be nutrient deficient. This is when looking beyond macros and calories are important, sometimes it’s really not just protein, carbs and fats
I eat white fish 1/2 weekly, so no fish oil supplement is needed. I favor red meat over chicken...despite both being protein, red meat carries more nutrient. Gelatin is supplemented daily, along with my muscle meat consumption, but I also consume other animal parts. I make my own bone broth and my current favorite is using chicken feet bones. (They break down easily and makes really gelatinous broth) Rice is infused with bone broth (simply replace the water you would boil rice with with bone broth) they taste amazing ! Shellfish, such as shrimps / oyster / scallops are eaten in small amounts almost daily (great source of f iron, zinc, copper and vitamin B-12
There are certain fiber I like, I do a raw carrot salad daily to help remove excess estrogen and regulate bowel movements. Occasional spinach, mushrooms, sometimes cooked tomatoes. I don’t ever do raw green, nuts or seeds, as they irritate my guts. Occasional dairy, esp good quality gelato ice cream (luckily we still get them here) but I also supplement with eggshell calcium. If you are unsure of where you are currently nutrient wise, you can always just plug your food in #Cronometer, that should give you a good idea of what you need
Be adventurous with food, keep exploring ! .
