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

## Pregnancy Gestational Diabetes Diet Calculation

Gestational diabetes happens during the pregnancy period. This diabetes is characterized by high blood glucose levels and it has a number of characteristics that are different from other forms of diabetes and it is the result of hormonal changes that occur in all women during pregnancy.

### Formula

**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**

Category | Factor |
---|---|

None | 1 |

Very little | 1.2 |

1 – 3 days per week | 1.375 |

3 – 5 days per week | 1.55 |

6 days per week | 1.725 |

Every day | 1.9 |

BMI value | Weight gain |
---|---|

<18.5 | 28-40 lbs |

18.5-24.9 | 25-35 lbs |

25.0-29.9 | 15-25 lbs |

>30 | 11-20 lbs |

[tab title=”Example”]

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

**Given,**

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

**To Find,**

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

**Solution**

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
