Wrong. So, so, so wrong! However this is how most people when on a "diet" think. Yet, there is ample evidence that the simple act of eating breakfast - every single morning - is a big part of losing weight. Just because "dieting" is most about cutting calories and moving more this doesn't mean skipping meals is the way to. If you are doing this, by mid-morning you are likely to be starving and therefore, more likely to enter the area of mindless nibbling, binging come lunch time and dinner and in turn setting yourself up for failure.
Breakfast provides you with energy needed to make it through the day and keep your body at the top of its game. Obviously the body gets energy it needs from the fuel that you put into it. After a night's sleep you need to replace glycogen, which provides energy to your body. Starting a day with breakfast affects your energy level for the whole day. You will be more physically active as you have refueled with energy after the "sleep fast" and therefore more likely to be active leading to the more calories will be burnt.
As previously said eating a healthy breakfast means you won't be as hungry during the day - therefore less likely to snack and essentially "over eat". When eating in the morning your bodies blood sugar remains level, but if you skip meals your body responds with an increased insulin response - so that when you do eat you are more likely to sore the calories as fat. A big breakfast makes you less likely to snack and risk the choice of a high fat snack option in your rush of curbing those starving hunger pains. Breakfast that include high fiber options help you stay fuller for longer - so choose your breakfast wisely. I always tend to pick Porridge Oats which are a slow releasing carb, sometimes with blueberries or a chopped banana on top.
