How do you decide if it's time to lose weight? Probably only when you are overweight. But the second question is, when is overweight and what is normal weight? Here are some methodologies for calculating your weight.
Body Mass Index (BMI)
Calculating your body mass index is a great way to know how much you should actually weigh. BMI is the ratio of a person's body to weight. Each one of us is individual, so we should not benchmark our magazine covers.

The BMI should be calculated using the formula: Weight in kilograms divided by height squared in meters.

The World Health Organization follows these guidelines:
BMI less than 18.5 - weight loss;
BMI from 18.5 to 25 - ideal weight;
BMI 25 to 30 - overweight;
BMI greater than 30 - obesity.

Waist and Thigh Formula
This calculation determines the proportions of your body. The formula is just right for those who think they have "big bones" or "make up". Height and weight are not important here, you just need to measure your waist and thighs. The volume of the waist is measured just above the navel, and the thigh is measured at the highest point.

Formula: Divide the waist volume by the thigh volume.

And now interpret the result. Less than 0.8 - excellent and optimal. This means you have little health problems and a low risk of heart disease. A score of 0.8 to 0.89 indicates an increased risk of heart disease and diabetes. And 0.9 and above is a high risk of health problems.

Thickness and height formula
This indicator shows how much you have to weigh according to your height. Modern research proves the importance of the waist-to-height ratio and warns against the risk of diabetes and heart disease.

Formula: The waist size should be at least half your height.

Cohen's tall statue
Michelle Cohen is the author of a Parisian diet that promotes the maintenance of normal weight throughout life without giving up sweets. According to this diet, Nicholas Sarkozy lost 8 kg in 2 months. Initially, four basic numbers are calculated:

Your weight when you were (or are) 18 years old when not following a diet (eg 70 kg)
Your highest weight except during pregnancy (eg 95 kg) Your minimum weight after 18 years following a diet with or without (eg 65 kg)
Your current weight (eg 90 kg)

Calculation: Add up answers A and B and divide by two (70 + 95/2 = 82.5 kg). This is the number Y.

Add the C and D answers and divide by two (65 + 90/2 = 77.5 kg). This is the number Z.

Add the numbers Y and Z and divide by two (82.5 + 77.5 / 2 = 80 kg). This is your ideal weight.

And a few more tips on how to calculate it accurately:

Only weigh at the same time of the day, preferably in the morning after 8 hours of sleep.

Exercise no more than 1-2 times a week on the same days of the week.

Measure your waist and thigh volume in the morning, before eating, so the numbers will be objective.

Height should also be measured in the morning, just after waking up, as you are tired in the evening, and your posture may be slack, so calculations may be inaccurate.
