It is really important that when you are trying to lose weight that you do not miss out meals, especially breakfast. When you first start eating in a day is when your metabolism starts so that you can burn more calories. Instead make sure that you have three meals a day and one or two healthy snacks. These meals should be balanced and not too big so that you feel really full afterwards. The portion size should corespond to your body size, so a smaller person should have a smaller portion.
TIP: One way that you can maximise your metabolism efficiency is to have a glass of warm water in the morning. This can be with some lemon juice or try Nettle tea as an alternative.
