Ever heard of the BMI? Do you know what it is? Here’s a little information about it. It stands for Body Measurement Index, and is the number you get when you divide your weight in kilograms by your height in meters squared. It’s important because it’s an objective way of knowing if you’re overweight, underweight or healthy. We say objective because, there are some things it doesn’t know, like your body fat or body muscle, and so it can be a little misleading if used wrongly, but in general, it’s a great way to figure out overall health risk and general courses of treatment.

So what’s a healthy BMI? 

BMIs between 18.5 and 24.9 are classed as healthy, or normal; those from 25 to 29.9 are considered overweight, and those under 18.5 are underweight. According to the National Center for Health Statistics, between 2015 and 2016 – 71.6% of adults aged over 20 were either overweight or obese. Being overweight or obese increases the likelihood of developing a large number of health issues, so it’s good to check your BMI to get an awareness of what your health risks might be.

This app is so helpful that I bought the premium version. In this first week of using The Energizer I have lost over 7 pounds!

This is the best app I’ve tried so far. It finds EVERYTHING. The insights are so helpful and have made me more conscious of what I’m eating. The recipes look great, interface is intuitive and user-friendly. I just upgraded to Premium and excited to keep using this app!

Easy to use, love the interface and how it has recipes and keeps me on plan. I upgraded to the full version, no regrets! I’ve tried many apps and in my opinion this one is the simplest to use and guides my choices!
