Are math equations effective for weight loss? Find out what the science says
According to the World Health Organization, the number of obese people worldwide Tripled since 1975Today, 40% of adults in the world are overweight. In this alarming scenario, methods that promise rapid and efficient weight loss continue to emerge. one of them Math equations for weight loss, whose reliability has been questioned. And if you still don’t know this strategy or are wondering if it’s safe to apply, read on and find out what the science has to say.
Mathematical equations for weight loss: what are they and how do they work?
The first thing that makes sense is understanding what this method suggests can make it easier to lose weight. To do this, we must go back to 1918, when nutrition expert Francis Gano Benedict and biostatistician James Arthur Harris published A biometric study of human basal metabolism. (or “Study of biometrics of basic human metabolism”, in Spanish).
This is the article in which “The Famous” first appeared. Harris Benedict equation: H = 66.4730 + 13.7516 W + 5.0033 W – 6.7550 A. was the goal Determining the calories that a person should consume daily, Which includes various aspects, such as gender, age, muscle activity, etc.
To develop their accounts, they have Foundations of basic metabolism as a starting point. That is, the heat production of each human being is at complete rest and 12 to 14 hours after the last meal.
Understanding the Harris Benedict Equation
To understand it, we must bear in mind the following:
- ‘h’ is the total heat production in 24 hours for a man;
- “w” is your body weight in kilograms;
- Your height is in centimeters.
- The “y” represents the man’s age in years.
The equation has acquired a version adapted to the woman’s body: h = 655.0955 + 9.5634 w + 1.8496 s – 4.6756 a. Therefore, these two original mathematical equations can be considered for weight loss.
Limitations of applying sports formulas to lose weight
The main point is that Harris and Benedict expected some conditions for their formula to be valid. They are: ‘w’ must be included in the interval [25.0, 124.9], Enters [151, 200]and e’ and ‘in [21, 70].
Another issue is that these mathematical equations for weight loss have been calculated based on primarily empirical evidence. The researchers took the regression measurements as a reference in 103 women, 136 men, and about 90 births.
This explains why the original formula has been revised over the years to arrive at Current equations to calculate GER (resting energy expenditure) for men and women. Son ellas: GER ♂ = 10 w + 6.25 s – 5a + 5/ GER ♀ = 10 w + 6.25 s – 5a – 161.
Also known as the basal metabolic rate, the GER expresses the amount of calories our bodies “burn” at rest at a “normal” temperature close to 37°C.
Conclusion: Are sports formulas for weight loss reliable or not?
It may seem strange to some people, but starting from a mathematical principle to lose weight makes perfect sense. It happens, so that the body begins to metabolize its energy reserves (which are mainly accumulated fats) and we are able to lose weight, A condition called a ‘calorie deficit’ should occur.
To be in a calorie deficit, It is necessary to “give” the body fewer calories than is necessary to generate energy To do daily activities. The best way to ensure this deficit is to calculate the calories needed by each person’s body and then determine a margin of deficit.
in this meaning, Mathematical equations for weight loss are useful in estimatingAccording to basal metabolism, how many calories that person needs to reduce to enter into a calorie deficit, thus promoting weight loss. What an excellent starting point for planning your diet in line with your nutritional requirements.
However, it is important to consider not only the gross enrollment rate in this calculation, but also the level of physical activity (NAF), to more accurately determine the total energy expenditure (GET) for each individual.
