I need to go beyond that a bit too. Learn more about addressing micronutrient deficiencies, sport specific dietary needs and I need to learn more about nutrition for the general public as a whole. It's easy for me to tell someone to eat meat and rice 4x a day and no carbs with meal 5 or whatever. But most people will not adhere to thst, and in order to help ppl they need to be able to comply.
I like to tell ppl the old 80/20 rule but most don't comply to that correctly either. They hear 80/20 and think 1 out of every 5 meals is a cheat. No way lol. 80% of your daily calories from meat, vegetables, fruit and rice or potatoes ect. And 20% of your calories are your decision. That's how I like to structure it. John meadows was big on that for most ppl.
If your eating 2500 calories a day, that means 2000 ate from your approved foods list and you get a protein goal. The other 500 cal is your 20% fun stuff.
I get ppl eating 4 meals and then have a 1500 cal dinner cheat. That's more then 50% of your calories and ppl don't seem to get it. They justify 1 out of 5 as 20% regardless of calories and run with it lol.
I've done it myself
