Online health diet calculator, which helps women to calculate the BMI, IBW, ABW, BMR, Weight Gain, Calories needed during pregnancy period. Gestational diabetes happens during the pregnancy period.

■ Body Mass Index (BMI) = weight / (height * height)
■ Ideal Body Weight (IBW) = 45.5 + (((height*0.393700787) - 60) * 2.3)
■ Adjusted Body Weight (ABW) = IBW + 0.4 (actual weight – IBW)
■ Basal Metabolic Rate = 655.1 + (9.6 * weight) + (1.8 * height) – (4.7 * age)
■ Calories = BMR * factor

A 27 year lady gets pregnant. She weighs 50 kgs and her height is 175 cm. She does exercises for 3 days per week. Find the calories, BMI, ABW, IBW, weight gain and BMR for her.


age = 27 years
height = 175 cm
weight = 50 kgs

To Find,

BMI, IBW, ABW, BMR, Weight gain, Calories


Step 1:

Calculate BMI (Body Mass Index) from the given formula,

BMI = weight / (height x height)
BMI = 50 / (1.75 x 1.75)
BMI = 16.3

Step 2:

Calculate the IBW (Ideal Body Weight) during pregnancy period.

Ideal Body Weight (IBW) = 45.5 + (((height x 0.393700787) – 60) x 2.3)
IBW = 45.5 + (((175 x 0.393700787) - 60) x 2.3)
= 45.5 + (68.8976 – 60) x 2.3
= 45.5 + (8.8976 x 2.3)
= 65.96

Step 3:

Calculate ABW (Adjusted Body Weight) (ABW) = IBW + 0.4 (actual weight – IBW)

ABW = 65.96 + 0.4 (50 – 65.96)
= 65.96 + 0.4 ( - 15.96)
= 65.96 – 6.384
= 59.6

Step 4:

Calculate BMR (Basal Metabolic Rate) Basal Metabolic Rate = 655.1 + (9.6 x weight) + (1.8 x height) – (4.7 x age)

BMR = 655.1 + (9.6 x 50) + (1.8 x 175) – (4.7 x 27)
= 655.1 + 480 + 315 – 126.9
= 1323.2

Step 5:

Finally, let us learn how to calculate the Calories level during pregnancy gestational diet.

Calories = BMR x factor
Calories = 1323.2 x 1.55
= 2051

Only pregnant women suffer from gestational diabetes. It can develop during the early stages of the pregnancy. If you carelessly handle this situation, the risk factor for both you and your baby’s health may increase. Due to gestational diabetes, you can bleed excessively during the time of delivery.

Most commonly, pregnant women in their second or third trimester are diagnosed with this type of diabetes. Thus, from the early stages of diagnosis, try to treat it and maintain a healthy gestational diabetes diet to control the sugar level in your blood.

When you are pregnant, the hormone present in the blood called insulin divides the food you intake to sugar and glucose.
