The phrase If It Fits Your Macros (often abbreviated to IIFYM) refers to meeting the individual macronutrient needs relevant to one’s goals and then filling the remaining calories with foods of personal preference. Meaning, eat whatever you want as long as it fits your macros.

What “eat whatever you want as long as it fits your macros” means is basically, eat right, but don’t get all caught up in the whole ‘clean vs dirty’ food debate that seems to still go on. If you want to eat whole grain bread, oats, brown rice, etc. etc. Then do it. If you want to eat white bread, white rice, and pop tarts, as long as it fits in with your other macronutrients and your goals in terms of caloric intake then it isn’t going to make much of a difference in the long run. It all comes down to personal preference.
IIFYM is achieved by following a structured diet similar to the below:
- 200lb man at 20% body fat wants to lose weight
- Maintenance Calories: 3000
- Calories to cut: 2400 - this is a 20% caloric deficit
- 1.5g protein per lb/LBM: (1.5 * 160) 240g
- 0.45g fat per lb/BW: (200 * 0.45) 90g
- Calories from fats + protein minimums: (240 * 4) + (90 * 9) = 1770
- Calories from reaching minimums taken from calories to cut: (2400 - 1770) 630
- He has 630 kcal left to fill with whatever foods he chooses (pop-tarts, pizza, cake, ice cream) and still lose weight as a result of remaining in a calorie deficit.

/īmēˈyə/

A woman who is and will always remain young—in the best ways possible. She has the heart, eyes, and laugh of a child. She loves (and dreams) like no other, sees wonder in everything the world has to offer, and enjoys all of it to the fullest extent possible. She is an excitable goofball, but she is also very understanding and sympathetic. She will listen to your deepest worries and give you the best advice she can think of, but soon after that, you can count on her to drag you away from it all and give you a great laugh and a fun time! She is truly a unique individual who deserves nothing but the best, because that’s what she gives of herself to everyone she encounters.

Fabricio: Me too. I’m really thankful to have her in my life.

Miya loves to smile and laugh. she’s a great friend and knows how to make you feel nice. She's Smart, Pretty And Loyal. She Has A Attitude Problems She’s A Handful And She's Crazy But She'll Love You. Some think she's an angel at times, but she can turn into a devil in seconds if you screw with her or people she cares about. She is quiet when you meet her but be ware she gets loud.Lastly Imiya often holds a deep pain inside of her. She laughs off any type of joke made at her expense but stores the memory deep down inside of her so try to have her open up and talk about it because all she Is waiting on is for somebody to listen 💯
That’s something imiya would’ve done
