I remember that my normal "mash" was pretty decent for the macros I was trying to hit (Note: now that I've calculated it, not sure if this is good or not). Anyone got a refresher for me on a good target? With the standard Corepower, Chipotle, Chicken Breast meal, my carbs are 95g, fats are 32g, protein is 105. That equates to roughly a 40/15/45 ratio. 1073 calories (although I frequently count more calories on the chipotle bowl if it feels "heavy".
You're within the generally accepted ranges- standard guidance, just ensure healthy fats and avoid simple carbs.
I'm curious where this is coming from. Do you have a reference?
There's data on all cause mortality as a function of carbohydrate and protein intake, but not much for fats. Carbohydrates show a U shaped mortality curve, with
both low and high intake associated with increased risk of death. The lowest risk was seen when carbohydrates comprised between 50-65% of calories. Protein has showed variable effect when stratified by age, with >15-20% associated with
increased mortality in middle age, while higher intake (>20%) showed net mortality benefit in people over age 65. But I've never seen a study where people consumed 45% of their calories from protein. That's extremely high, by any standard.
Taken together, I'd guess it's reasonable to consume 50-65% calories from carbohydrate, 10-20% protein (can err on the higher side of the range, to spare muscle when losing weight), and the remainder (~20-30%) fat. Not far off from the breakdown of "Blue Zone" diets, what people eat in areas known for longevity: 65% carbohydrate, 15% protein, 20% fat. Of note, those macronutrient numbers don't differ much from the standard American diet, which is 55% carbohydrate, 15% protein, and 30% fats. All calories aren't created equal.
FTR, I don't know if there is an ideal carbohydrate/protein/fat breakdown for weight loss, and I'm not of fan of diet being dictated by macronutrient content, rather than food type. My advice: avoid ultraprocessed foods, added sugars, alcohol, and build a diet around plants, with animal products consumed sparingly. That's a proven formula for maintaining a healthy weight and preventing disease.
