See, I hear conflicting shit on this and have had arguments with my buddies about this. So I'll play devil's advocate.
"Many of the studies are funded by the food industry, which has a clear bias. Kellogg funded a highly cited article that found that cereal for breakfast is associated with being thinner. "
Where did this idea come from?
"What is less commonly mentioned is the origin of this ode to breakfast: a 1944 marketing campaign launched by General Foods, the manufacturer of Grape Nuts, to sell more cereal."
Or, It could be a combination of both. https://examine.com/nutrition/is-it-really-that-bad-to-skip-breakfast/
The last link gives some pro's and con's with eating breakfast.
Now I'm going to copy and paste a reply to a similar thread I saw a while back.
"Professor Terence Kealey's book Breakfast is a Dangerous Meal highlights the many ways in which it is dangerous.
Because of evolution, humans did not naturally eat in the morning. As a result, our body provides a spike in blood sugar to cope with the natural fast we have. So if we eat breakfast (which in our society is usually full of carbs (i.e. sugar) and other foods of low nutritional value) then our blood sugar levels rocket up, which also increases our insulin resistance, eventually leading to type 2 diabetes.
Furthermore, eating breakfast increases our hunger throughout the day (contrary to prevailing wisdom) and makes it more likely for us to eat more calories throughout the whole day.
As other commentators have stated, many of the studies which try to prove that breakfast is good for us are flawed for two reasons: Firstly, they are nearly always funded by Kelloggs or similar, and secondly, they are based on correlation and not causation. This is because it is true that, generally speaking, people who eat breakfast are also more healthy than those who do not. However, this is because people who eat breakfast come from a higher socioeconomic profile than those who don't, and so generally do what they are told when it comes to health and nutrition - such as eat their 5 fruit and veg a day, do lots of exercise, etc., and to eat breakfast. They are therefore healthier in spite of the fact they eat breakfast, and not because of it. This then allows the studies funded by Kelloggs and other food companies to say "Hey look! People who eat breakfast are less obese!" Which then in turn allows bad news publications to say "Hey look! People who eat breakfast are less likely to be obese!" Which is a lie."
