Fast Metabolism? Slow Metabolism?

You worry about a "ast metabolism or a slow metabolism? You can't gain or lose weight, despite eating a lot or very little? You are really skinny and qualify yourself as a hardgainers? Or are overweight and believe you are diet-resistant and want to boost your metabolism?

But is there really such a thing as a fast or slow metabolism?

In this video we are going to have a look at the two components your metabolism is made up of, the BMR and TDEE, how size, age, gender and genes make your metabolism lower or higher, what role the amounts of muscle and fat mass in your body play in this and if you can really do anything to increase or decrease the whole thing.

For those of you wanting to look into the scientific research about this topic, these papers should be an interesting read, as they highlight how similar people have similar BMRs and TDEEs and how people diagnosed with "diet resistance" failed to accurately assess how much they had really eaten:

I wna speed up my metabolism. Im 15, and I spend 50% of my life exerciseing, and I don't eat much, yet I am 162. 6ft. Im not worried about my weight or anything, its just its annoying to havta spend hours every day exercising, and all weekend, and to count calories

[Evilcyber]

@someone9906 Well, it's either the exercising and the counting or eating less, eh?

The nice thing about the exercising is it also makes you look good! ;)

Genes are definatly the main factor when it comes to body fat. My brother is 21, drinks like a fish and eats whole pizzas to himself and doesn't gain an ounce, meanwhile I'm slogging my guts out down the gym, cutting all carbs and snacking on almonds and berries to stay slim, I mean WTF?

My sister eats like 3 grown men and has weighed 122 pounds for more than 7 years of her life! She doesn't go to work, school, OR excersise? ME however, am a picky and less eater and what I do eat I make sure its healthy. Why the hell do I weigh 150 pounds??

@Mauriscinasa If I calculated correctly, then your BMI is 18.6. You are very close to being underweight, but not dangerously so at the moment. I'd say keep working out and do allow yourself a bit more sweets along with the healthy foods you eat. With your stats you need more than 2200 kcal / day to increase your weight.
