\u201cI\u2019m tracking my macros<\/a>.\u201d<\/p>\n\n\n\n

\u201cI\u2019ll pass on that, it doesn\u2019t fit in my macros<\/a>.\u201d<\/p>\n\n\n\n

\u201cI\u2019m on the Macro Diet<\/a>.\u201d<\/p>\n\n\n\n

Macros seem to come up often in the corners of the internet and social media devoted to people trying to lose weight, improve their health, look better and feel better about themselves. But what the heck is a macro?<\/p>\n\n\n\n

With more information than ever available at your fingertips, and more diets out there than you have fingers and toes to count on, it\u2019s no wonder you might be confused. As an exercise science specialist<\/a> interested in physical health and nutrition, I\u2019ve got you covered.<\/p>\n\n\n\n

\u201cMacros\u201d is just a shorthand term for macronutrients: protein, carbohydrates and fats. They\u2019re the nutritional building blocks that all foods are made up of in various ratios.<\/p>\n\n\n\n

If you look at a nutrition label, you\u2019ll see that macros are measured in grams. But it\u2019s important to understand that the calories per gram for each macro aren\u2019t the same. Protein and carbohydrates each have 4 calories per gram, while fat has 9 calories per gram. In other words, fat provides more than twice the amount of energy per gram compared with protein and carbohydrates.<\/p>\n\n\n\n

People rarely eat proteins, carbohydrates or fats in isolation. For example, while chicken is widely considered a source of protein, it also contains fat. Almost every food contains more than one macronutrient.<\/p>\n\n\n\n

What macros do and where to find them<\/h2>\n\n\n\n

Beyond its job building muscle, protein also plays other critical roles in the body: as a component of enzymes, transporting nutrients and producing hormones. Sources of protein<\/a> include animal meats, eggs, fish and seafood, and dairy. While animal sources have the highest protein content, plant food sources, such as whole grains, legumes such as beans, and nuts and seeds also contain protein. You don\u2019t need to consume animal products to get adequate protein in your diet.<\/p>\n\n\n\n

The 2020-2025 federal dietary guidelines for Americans<\/a> recommend at least 46 grams of protein for adult females and at least 56 grams for adult males, although this may be too low for older adults, pregnant and lactating women, and people with high levels of physical activity.<\/p>\n\n\n\n

Carbohydrates<\/a> are the body\u2019s preferred energy source. They\u2019re found in bread, rice, pasta, fruits, dairy products, legumes and starchy vegetables. Simple sugars also fit into the carbohydrate category, and those are the ones to limit<\/a>.<\/p>\n\n\n\n

As for fats, there are different types<\/a>: polyunsaturated, monounsaturated, saturated and trans fat. Polyunsaturated and monounsaturated have the greatest health benefits and are found in things such as nuts and seeds and fish. Omega-3s are essential fatty acids that can reduce the risk of cardiovascular disease and are found in fatty fish such as salmon and nuts such as walnuts.<\/p>\n\n\n\n

Artificial trans fats are created by an industrial process. You\u2019ll see them listed as partially hydrogenated oils on nutrition labels for fried and baked goods. They increase the risk of heart disease and death<\/a>.<\/p>\n\n\n\n

Do calories matter?<\/h2>\n\n\n\n

In a word, yes, calories matter. But calories from different sources do affect the body differently.<\/p>\n\n\n\n

For example, 2,000 calories of junk food and soda are not going to help with appetite control the same way<\/a> that 2,000 calories of fruits and vegetables, whole grains, healthy fats and lean proteins will. Fiber, for example, is found in fruits, vegetables and whole grains and has been found to be a potent appetite regulator<\/a>.<\/p>\n\n\n\n

The good news is that the most important thing for weight management is caloric balance and consistency. In fact, evidence suggests that there is no \u201coptimal\u201d diet that can be applied to everyone, and that various weight loss strategies \u2013 different macronutrient distributions, intermittent fasting and so on \u2013 all balance out over the long run<\/a>.<\/p>\n\n\n\n

If you\u2019re attracted to a dietary approach that relies on tracking your macros, focus on getting a healthy balance of protein, carbs and fat<\/a>.<\/p>\n\n\n\n
