Coffee a metabolism-killer?

in Food and Nutrition
As I was browsing my daily websites, I came across an article named "Little Ways to be Happier and Healthier"

One of it's claims is that coffee before breakfast is a metabolism killer.
Just wondering what your thoughts were? (I have zero plans to give up my weekend coffee-before-breakfast routine)
Eat a little something before you caffeinate, okay? 'Caffeine before breakfast is a metabolism-killer,' says Haylie Pomroy, nutritionist to stars like Jennifer Lopez and Reese Witherspoon and author of The Fast Metabolism Diet. 'If you ingest coffee with no food on board, your body is more likely to lose muscle, instead of burning fat.'

    interesting. Not sure if I believe it. I will have to research but if it turns out to be true I will start eating a small yogurt while I brew my morning joe just to be on the safe side

    I've always read just the opposite, that coffee increases the metabolism. I work out either fasted or have milk with my coffee so it's a non-issue for me.

    I am one of those people that when told something, like to know WHY, hence why I get myself into strife on forums at times.

    The same goes for this article, although it is a nutritionist to the stars stating this as fact, she doesn't actually say WHY coffee would be a metabolism killer etc etc etc.

    I will take it with a pinch of salt - the article that is, not my coffee :laugh:

    I too have found this to be true. You need to wake your system UP before you introduce chemicals. I go by the rule 30 with in 30. 30 grams of protein within 30 minutes of waking. It sets me up for my morning walk and then I come home and enjoy my coffee

    Hey, if she's the nutritionist to the stars and has written a book it must be true........I'm convinced, no need for science here. /sarcasm

    I would have to disagree also with the article, caffeine releases endorphins making you happier ! My sister was diagnosed with bipolar, and the dr. Even recommended her to drink a coffee a day to get the endorphins going ! On the other hand , ccaffiene is a hunger suppressant along with smoking, so if someone is drinking coffee several times a day they could be missing signals from their bodies that it's time to fuel with food . Moderation is key. I've cut way back on my coffee I take , just two cups in the am ...then water the rest of the day.

    no real nutritionist believes in 'diets' so that kind of shows off their credibility.

    Hi! I'm no nutritionist, but you have lost over 50lbs, so you must be doing something right!

    I've recently given up a LOT of my unhealthy habits, but coffee is not, and never will be one of them!!!! She says sugar before food kills metabolism. Maybe it does. For me, I'm not human before I have my 16 ounce cup of Folgers with a tablespoon each of sugar and sugar free flavored creamer.

    I looked at some reviews of her book on amazon. It sounds like a 28 day crash diet, with most days being WELL under 1000 calories a day. It's not meant to help people live healthier lives by making long term changes.

    I read that article as well and I don't believe it. I know plenty of extremely thin and fit people who drink coffee first. A lot of people cant even eat before 10am, yet remain thin. If one little thing like drinking your coffee without food was a weight loss deal breaker surely I would toss my beloved cup a joe out the window but its not, so I am going to enjoy and savor my java instead, cheers!:drinker:

    Indeed!!!

    Yeah, Ive never heard of coffee being a metabolism killer. The complete opposite actually. everything in moderation yeah, but having a cup of coffee in the am before breakfast isnt "killing" anything.

    I lived for nearly a month on very little caffeine after recent surgery it just made me feel sick and I noticed NO change whatsoever in my weight loss.The only change was that I was horrible to live with as I was fairly unapproachable in the a.m. to say the least. I'm back on my black unsweetened coffee and harmony is restored. :smile:

    My friend is a body builder and a trainer of pro athletes. He admonished me for drinking black coffee during my morning workouts. He said something along the lines of it releasing cortisol and stripping the body of other nutrients. I have stopped drinking coffee during my workouts (I get my caffeine from my preworkout sup) and now drink water instead, and I do feel better. I save my coffee drinking for the office after my morning workout.

    I drink TONS of coffee and I don't believe it has hurt my metabolism. Even if it did have an effect, not sure I could give it up : )

    What is it in the coffee that does that then? Did he tell you why caffeine in coffee does that and caffeine in your pre workout doesnt? Seems like broscience to me.

    Original article as well.

    This is the kind of crap that people (like myself in the past) focus on that truly doesn't matter and is a waste of time worrying about.

    Coffee a metabolism-killer

    I read both the positive and the negative reviews of the book on Amazon. Here's what the most helpful positive reviewer claims: "For example, if you can't give up your coffee, eat first. Coffee on an empty stomach is a metabolism killer because it pulls sugar from your muscles to balance hormones."

    So it's not about coffee being a metabolism-killer in general, just the idea of having it on an empty stomach. I don't know if the statement above is true or not. It probably depends on how long you wait before you eat something. I do know that coffee is quite acidic and so drinking it on an empty stomach can make you feel lousy. I prefer to have my coffee after meals, but that's just me.:smile:

    Bull.

    Anything you consume takes 20 min to 20hrs to be absorbed. Caffeine bioavailabilty is relatively fast with peak bioavailabilty at about 2 hrs (as shown by blood sampling studies). In general, unbound sugars have a bioavailabilty that is quite higher with an initial peak at about 30 min.

    <insert gif of food slurry in stomach>

    Now, let's assume that wasn't true. What is this "sugar being pulled out of muscles"? Let's say its a bit of glucose and let's assume she's right for the sh!ts and giggles. Would that be the same glucose that is used by your brain when you sleep? Or that glucose that is used up during exercise? Hmmm, gotta stop sleeping and exercise, too. 'Cause hormones.

    A study that says something: http://ajcn.nutrition.org/content/51/5/759.short

    Caffeine does affect blood glucose levels - in diabetic rats and at levels of 50 g/ kg weight.

    Another study, with science: http://imr.sagepub.com/content/40/6/2220.abstract

    That's about 1/2 cup per kg. so I'd have to drink 40 cups of coffee (long term and be diabetic) to see an impact on blood glucose (according to that study).

    Who known maybe that nutritionist isn't blathering and has a secret lab.

    < insert gif of secret lab>

    Time for coffee. I shouldn't read the forums in bed. They get my hormones all unbalanced.

    Any difference it makes in metabolism is probably so small you have to be ingesting a bottle of caffeine pills to actually make a difference.

    Generally I consider anything to be on a television spot, a blog, or a site regularly covering celebrity things to be hype. It seems that any nutritional research becomes about weight. And who knows what the actual study for that idea was? It very easily could have been one side observation in a laboratory experiment focusing on something else. There's a good chance it has never been actually seen in an actual intake, just cells reacting to something injected in them.

    Essentially I don't believe anything until I see it published and find out what it exactly is. I'm sure many things are true, but there's way to much hype for me.

    I have read her book. She says a lot of things that can be proven otherwise. For example, she says "don't fast before you go fast" meaning do not train fasted. I have seen the greatest results in my body when I train fasted. I get more done when I train fasted. The only thing I have while fasted IS coffee. It really depends on the person though, I suppose.

    I don't know, that Amazon reviewer sounds like they know more about this process than you. I think I will stick to Amazon reviews for my science, thank you very much.
