When you are eating out at a restaurant, don't automatically consider the serving on your plate to be "one serving". Most restaurants serve food that is two or three times the amount dietary guidelines recommend. Take half of your plate and instantly put it in a to go box so that you don't end up consuming more calories than you want to.
Calculating the exact number of calories to eat per day can be long, hard and tedious work. S,o instead of counting the calories of every single food item and entering it into your calculator, round the numbers off to the nearest hundred, and strive to come in at 100 calories under your intended goal for the day.
Don't skip meals. Skipped meals will inevitably lead to binge eating, which will mean more calories that you don't need, and more weight you have to work out. Even if you don't feel like eating, particularly in the morning, have a small yogurt or a piece of fruit so that you can keep your hunger under control.
