Metabolism

in Health and Weight Loss
Alot of people on here seem to beleive that what and when you eat doesn't effect your metabolism / weight loss.
However here are some facts :)

Basal metabolic rate (BMR) - is the amount of calories / kilojoules burned at rest and contributes 50-80 per cent of your energy used.

Your BMR rises after you eat because you use energy to eat, digest and metabolise the food you’ve just eaten.
The rise occurs soon after you start eating and peaks two to three hours later.
This rise in the BMR can range between 2% - 30%, depending on the size of the meal and the types of foods eaten.
For example:
Fats - raise the BMR 4 per cent
Carbohydrates - raise BMR 6 per cent
Proteins - raise BMR 30 per cent
Hot spicy foods - like chili, increase you BMR for hours after you eat

By this logic, if you eat more often and more protein your BMR is higher and you're burning more calories

    Yes, great! That is why I joined the Food Lovers Fat Lose System because the small healthy meals and the healthy snacking every couple hours until one hour before bedtime keeps your body in fat burning mode. I feel my metabolism coming back to life and I am seeing a difference already!!! Good advice! Good science!!! Thanks for confirming what i"m doing!!!

    Yeah. That's been largely debunked.

    ^^ this.

    roughly 10% of the calories in a meal are used to digest it. So if you eat 6 x 300 calories meals a day you are burning 180 calories through digestion, that same as if you were to eat one 1800 calorie meal...

    Eat how you want, hit your daily calories/macros and stop trying to micro manage your food intake.

    My metabolism is" snail slow." It is called menopause and age.

    Here is more science that points in another direction.

    http://www.leangains.com/2010/10/top-ten-fasting-myths-debunked.html

    http://bradpilon.com/weight-loss/ideal-metabolism/

    All those OP assumptions seem insignificant to me since I lost 60 lbs doing intermittent fasting and have been healthily maintaining for over a year. My DXA scan and lab reports from my doctor checking my hormone levels throughout the process proved I did not go into starvation mode, lose lean body mass, or break my metabolism. My doctor is very happy with my reports at the moment, I am healthier then I have ever been in my entire life at almost 52 years of age. That is enough science to convince me already.

    Don't get me wrong, different things work for different people & depending on your own body it could have a much smaller effect than on others,
    But working in gyms & also with people I know personally, I've seen diets that support this work for so many people!
    & It definately hasn't been "debunked" I'm qualified in fitness and have studied anatomy and exercise physiology, so I have learnt about metabolism.
    I also checked it out again on an Australian Government website that was updated the start of this month before posting.

    Your evidence is purely anecdotal.

    No, because you burn the same amount of calories digesting 2000 calories if you eat it over 5 meals as you do if you eat it at 1 meal.

    Amazing work on your weight loss! :D

    I did look at those websites, but the first thing I noticed is that they're trying to sell you something, which instantly discounts the content for me to be honest.
    My information is what I've learnt studying to work in fitness and I confirmed it on an Australian Goverenment website.
    & depending on the individual it can have a variance of effect.

    To bad you got sold some bad science in your nutritional classes.

    I will post what I posted on the other thread you were spreading this lack of understanding on:



    Calories and macros being equal - meal timing is irrelevant to weight loss.

    agreed OP, and give them as much attention as you have to your other studies.

    You're dabbling in minutia.

    1. Get Active
    2. Strength Train
    3. Don't eat too much.

    What Sara posted here!! Thermic Effect of Food does not constitue and overall increase in metabolism if calories and macros and held constant. This is missing the forest while looking at the trees. Useless.

    Really? You learnt about metabolism? Maybe you should have learned it.

    If I eat ice cream, my body has to produce more heat to maintain my body temperature. Therefore, as long as we eat everything frozen, it shouldn't matter. Frozen TV dinner? Just blend that crap up and drink it like a frosty.

    Learnt is a word. Maybe you should use a dictionary before challenging people.

    What do you mean this is America? This is the internet. There are people here from a whole variety of different countries. In Canada, the word color is spelled "colour." Is that word therefore considered misspelled? Learnt, for the record, is less common, but still considered correct spelling in America.

    There is no such word as "cookt" so there is no such word as "learnt".
