There are some specific problems that can come about for an obese mom-to-be of which she needs to pay special attention. Dads should also know about these so they too can look for signs of a potential problem.

A lot of attention has been focused in dealing with overweight issues but much as this is justified, little attention has been directed to tackling matters pertaining to being underweight. Scientifically speaking, people who have a Body Mass Index (BMI) that is under 20 are considered to be underweight.

There are many helpful weight loss calculators online. These calculators can give estimates of your BMI (Body Mass Index), daily calorie needs, how many calories you burn during exercise and much, much more.
