Before you start losing weight it is a good idea to prepare yourself on several fronts. Making sure that the motivation factor is present is one of the first things but most importantly you should learn to use a weight loss calculator to make sure you are burning more calories than you take in each day.
The process is simple. First calculate the amount of calories you need every day. For most people, to lose weight, you should consume 1200 to 1500 calories per day. The calculation is easy. All you do is input your height and weight and level of activity then do the math.
This weight loss calculator will tell you the amount of calories you need to be able to maintain your current weight. Since you do not want to maintain your current weight, you want to shed some of those pounds then you need to take in about 500 calories less than what that calculation gives you.
Next, calculate how many calories are in each serving of food you eat. You may have to practice at measuring out just exactly what a serving size is to get good at it. Make sure you are accurate and aren't sneaking in just a little more here or there. Those little sneak-ins will add up and all of a sudden you will wonder why you are not losing the weight you want anymore.
Go buy yourself a book that lists calories for servings of food that do not come with labels like fresh fruits and vegetables, or do a search online. You might be able to find a list for free online. Do the same for eating out and when you do eat out make better choices based on what you learn online.
Know how many calories are in each gram of fat, carbohydrates and protein. This will help you when you figure out the percentages of each one that you need each day. So, keep this in mind: Carbohydrates and proteins have an equal amount of calories in each gram at 4 and fats have 9 calories per gram. Fats should make up no more than 30% of your daily calorie count. Carbs and protein should make up 50% and 20% respectively of your daily calorie intake.
Make sure they are good carbs though. The carbs you get from breads and cereals and sugar are overly processed and you should avoid them completely. Basically anything that is made with "white" products. White flour, white sugar, white rice should simply be avoided. These are all considered bad carbs and do nothing for you accept keep you gaining weight and fat around the middle.
The best way to use your weight loss calculator is to do it all yourself. Keep careful records in a small notebook in your purse or in your car so it is handy when you need to write something down. Maybe you could even get an app for that for your phone so you can keep all the information you need right at your fingertips.
