9.  You MUST eat at least 5 meals per day.  Fact of fallacy?  
Answer:  Fallacy
There is a huge myth that has been floating around the fitness circles that eating more meals per day speeds up your metabolism, thus, helping you lose more weight.
It doesn't.
I am a fan of multiple, smaller meals.  I, myself, consume 6-7 per day.  However, this is not because of some magical metabolic change that occurs due to the number of meals consumed.  I eat that many mainly b/c I have to pack in so much food in order to add muscle.  Too, eating multiple times per day helps with macro/micro nutrient uptake, insulin regulation, etc, etc.  It has its benefits, but aiding in metabolic rate and therefore weight loss is not one of them.
If you can't squeeze in that many meals per day due to schedule, don't sweat it.
