Just on Mondays, though. Because you only measure your macros on Mondays, after eating crap since Tuesday, because you’re going to start on Monday, right?
What is a Macro?
Macronutrients (macros) are nutrients that provide calories or energy. Nutrients are substances needed for growth, metabolism, rebuilding and all basic body functions. There are three macronutrients that all food is categorised under:
- Carbohydrates (CHO)
- Protein (PRO)
- Fat
What do Macros Do?
On one hand, all macros provide calories (energy). Carbohydrate provides 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. Aside from providing calories to fuel various functions, each macro has a different set of responsibilities in the body.
We need CHO because:
- They are the body’s main source of fuel.
- They are easily used by the body for energy.
- All of the tissues and cells in our body can use glucose for energy.
- They are needed for the central nervous system, the kidneys, the brain, the muscles (including the heart) to function properly.
- They can be stored in the muscles and liver and later used for energy.
- They are important in intestinal health and waste elimination.
We need protein for:
- Growth (especially important for children, teens, and pregnant women)
- Tissue repair
- Immune function
- Making essential hormones and enzymes
- Energy when carbohydrate is not available
- Preserving lean muscle mass
Fat is essential for:
- Normal growth and development
- Energy (fat is the most concentrated source of energy)
- Absorbing certain vitamins ( like vitamins A, D, E, K, and carotenoids)
- Providing cushioning for the organs
- Maintaining cell membranes
- Providing taste, consistency, and stability to foods
Why Measure Macros?
As you can read above, macros provide calories. We need enough calories to support exercise but NOT body fat. One reason for measuring macros helps to ensure that you’re getting the correct amount of calories in. The other reason is to ensure that you’re giving your body the correct amount of nutrients it needs to fuel and recover from exercise, and for basic human function.
Food quality is more important than quantity though. You can’t out-measure a shitty diet.
How to Calculate Macros?
There are a ton of different methods but they essentially come down to a few differences. One thing most methods do have in common is that they should be based on the individual’s body composition and levels/type of activity.
- Calorie Based: These methods only calculate macros in order to calculate caloric intake and they do so under the belief that weight management is based simply on balancing calories in and calories out. There’s much more to that equation. More importantly, this method leaves people thinking that a calorie is a calorie, and it’s not.
- Sustainability Based: These methods keep food categorised at CHO, fat and protein instead of calculating calories. They also place a high emphasis on food quality. The changes implemented in one’s diet are intended to be lifelong so change is gradual and maintainable.
- Sports Based: These methods have been founded on systems used for athletes in weight category sports such as martial arts, weightlifting, and powerlifting. Or in sports that simply require an athlete to be at particular body weights for optimal performance or aesthetics. Such methods are characterised by having “cutting,” “building” and “maintenance” phases.
Depending on the individual and their needs, each method has it’s place. For example, if someone had an issue with balance – you know, the all or nothing sort – I wouldn’t have them using the sports based methods because they’d end up stuck in one of the phases. Similarly, if someone is really good at understanding what their body needs, I wouldn’t have them measuring macros at all!
Quality and quantity both matter, but there’s no point in measuring quantity if you’re getting the amounts in through shitty food.
