The Results in the calculator is based on Mifflin St.Jeor equation, which is regarded as one of the best Metabolic rate equations. Some supporting evidence below
The results and conclusion, according to Frankefield (2013):
Result: The Mifflin St. Jeor equation was unbiased (95% confidence interval −26 to +8 kcal/day), the Livingston equation tended to underestimate true metabolic rate (95% confidence interval −63 to −25 kcal/day), while all other equations tended to overestimate true metabolic rate.
Conclusion: The Mifflin St. Jeor equation is confirmed as a useful prediction equation for resting metabolic rate in community-living ambulatory adults of various body sizes

The Macro Requirements is further based on % split of the respective calorie requirements. By default it show the most commonly suggested Macro split i.e. 40% Calories from Protein, 40% from Carbs and 20% from Fat.
What is Basal Metabolic Rate?
Basal metabolic rate (BMR) refers to the minimum number of calories needed for resting body to function. The calorie and macro calculations provided above are directional and vary based on Climate, Age, Diet (both Macronutrients and micronutrients), Stress levels, gender (hormone levels, menstrual cycle, pregnancy), body composition etc.
What are Macro nutrients?
Carbohydrate:
These are sugar molecules. The body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.
Proteins:
Protein is in every cell in the body. Our bodies need protein from the foods we eat to build and maintain bones, muscles and skin. We get proteins in our diet from meat, dairy products, nuts, and certain grains and beans. Proteins from meat and other animal products are complete proteins. This means they supply all of the amino acids the body can't make on its own. It is important to get enough dietary protein. You need to eat protein every day, because your body doesn't store it the way it stores fats or carbohydrates. How much you need depends on your age, sex, health, and level of physical activity.
Fats:
Fats give you energy and help your body absorb vitamins. Dietary fat also plays a major role in cholesterol levels. Not all fats are the same.
You should try to avoid:
Try to replace them with oils such as canola, olive, safflower, sesame, or sunflower. Of course, eating too much fat will put on the pounds. Fat has twice as many calories as proteins or carbohydrates.
