How to calculate macros and calories


How to calculate macros and calories?

Nutrients are environmental substances which are used for energy, growth, and bodily functions by organ. We will explain how to calculate macros and calories. which helps us to take a limited amount of calories daily as a result our weight loss process gets started. 



Calculating your macros: 

Calculations are used to determine how many grams of protein, carbs and fat you need each day in order to meet your weight goals.

Meeting your macros: 

Once you know your macros, you just need to stay within them each day. Food intake is tracked and adjusted as needed.

Macronutrients

Depending on the nutrient, these substances contain calories in small amounts or larger amounts.
Those that are needed in large amounts are called macro-nutrients.

There are three macronutrients required by humans: carbohydrates (sugar), lipids (fats), and proteins. 

Each of these macronutrients provides energy in the form of calories also all are required elements to our body.

Carbohydrates :

Carbohydrates are the sugars, starches, and fibers found in fruits, grains, vegetables, and milk products. Carbohydrates are classified as a simple or complex carb.

Carbohydrates are found in foods you know are good for you like vegetables, roti, bread, and ones are bad you know are not doughnuts, cake, pizza.

The glycemic index measures how quickly and how much a carbohydrate raises blood sugar.

High-glycemic foods like pastries raise blood sugar highly and rapidly other hand low-glycemic foods raise it gently and slowly.

Calories

Calories are a measure of energy.  The technical one calorie is the amount of energy required to heat 1 gram of water by 1 degree Celsius. 

There are lot of ways to calculate Calories for a label. we explain here which is most accurate and famous.

being the 4-4-9 formula,  4-4-9 adjusted for fiber, and At water Factors. 

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

Manufacturers often use 4-4-9 or 4-4-9 adjusted for fiber, and the USDA uses Atwater Factors. 

To calculate using 4-4-9 

which are average conversion factor values, the following formula is used:

  · Protein grams x 4 = Cals from Protein

  · Carbohydrate grams x 4 = Cals from Carbs

  · Fat grams x 9 = Cals from Fat

Example :

Different foods have different caloric contributions per gram.  

For example, 1 gram of fat from one food may yield 8.4 Calories,  while 1 gram of fat from another food may yield 9.37 Calories.  

For fat, the values range very near 9 Calories, but it is not exactly 9 Calories.  Same concept with a gram of Protein or Carbohydrate.  

 4-4-9 vs Atwater formulas

Example of calculations for Great Northern Beans using the 4-4-9 vs Atwater formulas, based on the following:

36 grams beans containing amount if macros

  · 22.2g Carbs

  · 7.8g Protein

  · 0.26g Fat

  · 13.3g Fiber

Using Atwater Factors:

  · 22.2g x 4.07 = 90 Cals from Carbs

  · 7.8g x 3.47 = 27 Cals from Protein

  · 0.26g x 8.37 = 2 Cals from Fat

  · Total = 119 Cals

Using 4-4-9 formula:

  · 22.2g x 4 = 89 Cals from Carbs

  · 7.8g x 4 = 31 Cals from Protein

  · 0.26g x 9 = 2 Cals from Fat

  · Total = 122 Cals

macros are simply short for macronutrients and refer to protein, carbohydrates, fats, and technically alcohol in food as all details mentioned on label. 


It’s all nutrients that are consumed in large amounts (lots of grams).  Fiber could technically fit here as well.

Nutrient             Calories
Protein                  4
Carbohydrate        4
Fat                         9
Alcohol                 7
Fiber                     2


Technically, diets don’t work in calories (little c) but in kilocalories (1000 calories, kilo = 1000) or Calories (big C).  as per 1000 calories is 1 Kcal but most people use calories and Calories.

Most of food brands are doing rounding, Legally numbers can be rounded up or down depending on the actual amount of the nutrient.  

So 5.4 grams of protein becomes 5 on the label.  
2.7 grams of fat would round up to 3 grams.
10.3 grams of carbs becomes 10.  

Annoyingly, companies can actually round any value less than 0.5 down to zero. So a food that has 0.4 grams fat is listed as zero.  

Why most of the products mark trans fat as 0?

It’s the same reason they often use absurd serving sizes.  If you take a food that has 0.8 g of fat per serving (which rounds to 1 gram and 9 calories) and cut it in half, you get 0.4 grams of fat per serving which rounds down to 0 and you can list it as zero calories.
