There is so much misinformation in this article.
"slowing down your metabolism, will occur and eventually promote weight gain" - Thats why there are so many fat anorexic people right?
"this first meal of the day helps boost our metabolism" Not true. Total macro nutrient intake always wins - If thats divided up over 6 meals or 1 makes no difference. This has been shown countless times in the literature, which I would link but it seems like you have no interest reading any.
"learning to stop eating at night can be extremely difficult " Whats wrong with that? You havent even defined what you mean by habits.
"contradictory information that circulates about everywhere about nutrition" Well done for adding more misinformation to the internet!
As a personal trainer and nutrition expert I would tend to agree with you here. Too much vague information that doesn't apply to every person's metabolic type. We all have varying metabolic types, here is an OK article explaining what metabolic typing is: http://www.beyond-diet-reviews.com/how-to-determine-your-metabolic-type/
After a 10 minute search I could not fine any scholarly articles on the subject.
The first meal of the day may help boost some people's metabolism, but not everyone's! I'm on a 16 hour Intermittent Fasting Protocol and don't eat until 3-4pm every single day. I am in the best shape of my life and feel GREAT after following this for over a year.
Hate to have to call people out but that is what this community is all about, TRUTHFUL, EVIDENCE BACKED information. Thanks @depth
