Diabetes Macronutrient Calculator

Carbohydrates, proteins, and fats are the primary sources of nutrient providing energy for our body. Proportion of this macronutrient requirement varies between individuals, specifically for diabetes to control their blood glucose level.


Macronutrients are nutrients providing energy. Nutrients are substances require for the growth, metabolism, repair, and for other bodily functions. Since “macro” means large, macronutrients are nutrients requiring in large quantities. There are three primary macronutrients; they are carbohydrate, protein, and fat.


Carbohydrate is the main energy source of energy and thus comprises the main bulk of the average human diet. It is require for proper functioning of your tissues, cells, brain, heart and nervous system, a constant supply of carbohydrate is require. Carbohydrate is necessary for intestinal health and waste elimination. One gram of carbohydrate provides four calories of energy.

You need carbohydrate in large quantities as a major source of energy to cover 55% to 75% of calories requirement of every meal. Healthy source of carbohydrates are whole grains, vegetables, fruits and beans. Unhealthy carbohydrate sources are white bread, pastries, sodas, and other refined or processed foods.


We need protein for growth (particularly for children, pregnant women, and sports persons), tissue repair, hormones & enzymes production, immune function, maintaining lean muscle mass, and provide energy when carbohydrates are not available. One gram of protein provides four calories of energy.

We need protein as a source to cover 10% to 15% of calories requirement of every meal. Healthy protein sources are milk, cheese, yogurt, beans, soy, eggs, seafood, white-meat poultry, lean beef, etc.


We need fat for normal growth & development, help absorb fat-soluble vitamins (such as A, D, E, K and carotenoids), protecting organs (such as heart) by cushioning them, and provides energy. One gram of fat provides nine calories of energy.

We need fat as a source to cover 15% to 30% of calories requirement of every meal.  Healthy fats are monounsaturated fats (oils of olive, canola, sunflower, peanut, and sesame. Nuts such as almonds, peanuts, macadamia, hazelnuts, pecans, cashew, etc.), polyunsaturated fats (Oils of soybean, corn, safflower. other sources are walnuts, seeds (sunflower, sesame, pumpkin, flaxseed), fish (salmon, tuna, mackerel, herring, trout, sardines), soymilk and tofu.

Unhealthy saturated fats are high-fat meat (beef, lamb, and pork), chicken with skin, whole-fat dairy products, butter, cheese, ice cream, palm and coconut oil. Unhealthy trans-fat are bakery items (pastries, cookies, doughnuts, muffins, cakes, pizza dough), packaged snack foods (crackers, microwave popcorn, chips), stick margarine, vegetable shortening, fried-foods (French fries, fried chicken, chicken nuggets, breaded fish) and candy bars.

Macronutrients calculator

To use the macronutrient calculator, to require to enter your weight, height, age, gender, activity level and press calculate. You will be presented with your body mass index (BMI), basal metabolic rate (BMR), daily calorie's requirement, ideal body weight, weight category, how much calories your need to cut for healthy weight loss, macro nutrients to maintain the present weight and macro nutrient's requirement for weight loss.

Low carb & Low fat diet

There are numerous studies there one group supporting low fat (high carb diet) and other group supporting low carb (high fat diet). When you go through all these studies, it is very confusing and we will not able to arrive any conclusion.

We need more energies, easy source of energy is carbohydrate thus choose it for energy requirement of about 55% for immediate use. Next comes fat, which can provide very concentrate energy choose it as a source for about 30% calories requirement. Protein will fulfill the balance energy requirement of about 15%. This is the optimal balance between low & high carb/fat diet. Each individual is different, thus you may require modifying your diet based on how your bodies responds.

Are you a diabetic? After following this calculator suggestion, still your blood-glucose level is not responding, simply cutdown carbohydrate further by proportionally increasing the fat (1/2 of carb grams) or protein (same grams of carb).
