If you take the grams of protein and multiply it by 4 calories, take the grams of carbs and multiply it by 4 calories and the grams of fat and multiply it by 9 calories, you actually get close to the healthy recipes number of calories listed on the package for things. If it’s healthy recipes off a little that is probably because the numbers aren’t exact. But generally it’s accurate. This was quite mind-blowing when I first learned it. At least for Fat and Carbs, there are many subgroups within the main group and healthy recipes it is good to know them too. To learn more about this people need to read Marcus’s sticky on Nutrition for weight loss, http://forums.johnstonefitness.com/s...ead.php?t=1222 . It should be required reading for anyone that comes to the forum. It’s good to know this stuff because for fat loss, people recommend a certain macronutrient split based on calories (not grams). So if you eat 2000 calories a day and you want to eat 40% protein, 40% carbs and 20% fat, then you would eat 800 calories of carbs, 800 calories of protein and 400 calories of fat.
