Speed-up Your Metabolism




Introduction: Speed-up Your Metabolism

    We sometimes look at our friend or relative and think "Wow... how can he/she eat so much food and not get fat at all!!"  Well, the answer is very simple: Metabolism.

In this easy-to-follow instructable I'm gonna show you how you can speed-up your metabolism (and even lose some weight in the process) with some very basic guidelines and simple steps, just by eating and drinking what you always have been, not by some miracle diets or dangerous experimental procedures or drugs.

If you follow the steps and guidelines of this instructable, you'll get / be able to:

   1. Eat large amounts of food and not get fat at all.
   2. Lose some weight.
   3. Less laziness.
   4. Less prone to get sick.
   5. Healthier and more efficient body.
   6. A good-looking aesthetic body.

I'm also gonna clarify some myths about food, weight-loss and exercise related stuff.

NOTE: I am not gonna go very deep into nutrition, like complete diets or food programs. Diets/food programs don't work the same for everyone. If a particular diet worked for your friend, chances are it won't work the same for you, everyone has a different body. Consult your dietician for more info on this.

Step 1: The Basics

I'm going to begin explaining some of the very basics of our metabolism and how does it work.

Metabolism comes from the greek metabolé, wich means change, transformation, what cells experiment in our body when they change from organic substances to energy, in order to fulfill the vital functions of the body.

To put it simple, the metabolism is the speed with which the body converts food into energy, it can do so quickly or slowly. When it happens quickly, it usually means no significant weight increase, because everything we eat is processed quickly and doesn't store nutrients as fat, thus causing the weight and volume to stay steady.

In the other case, when the metabolism is slow, the nutrients exceed the normal requirements of the body, so they go into storage - as fat. The metabolism is a very complex process, but we're gonna keep it simple as to only focus on the fat reserves and how we can control them.

Now, we all know what calories are: A calory is a unit that measures how much energy a food provides to the body. The more calories you eat, the more energy you put into the body, but you need to provide the right amount or otherwise the excess energy goes into storage. The measure of the rate at wich a given person burns energy in the form of calories at rest (ie, while you sit and do nothing), is called Basal Metabolism.

The speed of the basal metabolism is regulated by a number of factors. To some extent, basal metabolism is inherited, passed from parents to childs through genes, but sometimes health problems can affect the basal metabolism and its efficacy (we'll talk about this ahead). This doesn't mean that you can't change it's speed, there are still many ways to accelerate it.

Ok, enough chatter, let's get to work.

Step 2: Foods

Myth #1. "People who eat a lot are fat."
Myth #2. "Skipping meals means less calories and more weight loss."

That's stupid people saying stupid things. Knowledge is power, and I'm gonna give you knowledge about this, here are some facts for you to consider.

FACT #1: When you skip meals, you're effectively telling your body that there's not much food available, as a result the body enters "survival mode". This means that the metabolism slows down to consume as less energy as possible, and a portion of the food you eat in survival mode, automatically goes to reserve (fat).

FACT #2: Diets that starve you, or skipping meals on purpose, does gets you to lose weight, BUT at that point any weight loss comes mostly from water and muscle, not fat.

"Ok... So how many meals?"

People usually eat 3 times a day, 3 "big" meals that is, forcing the body and metabolism to overwork those 3 times a day. What many people don't know, is that we must eat at least 5 times a day.

Eating many times a day helps the metabolism to stay active a lot longer, instead of just 3 times a day. Imagine you're in a car and want to get to the movies. What's the fastest way to get there? You can drive at a medium/fast constant speed, or drive slowly, and occasionally press the gas all the way to the bottom to give the car a rush, only to slow down again. The best way to keep the engine working, consuming fuel, and to get to the movies fast, is to drive at a constant speed. The same applies to the body. 5 small meals will keep the metabolism active, and most importantly, you won't get hungry.

Eating 5 times a day, or eating every 2 or 4 hours, it's your choice and depends on your body and your likings, but it's one of the most important rules to speed-up your metabolism.

By eating frequently you achieve the following:

1. Eating frequently prevents hunger pangs and curbs over eating.
2. Eating more often keeps your metabolism working quickly so you burn calories more efficiently.
3. Food is also absorbed more efficiently and quickly when we eat regularly.

"Ok I hear you, I can eat 5 meals a day, but how much can I eat?"

You need to know about portion control. Eating five times a day means you can eat enough to satisfy you, but its important to know how much you can eat in relation to your body size and there is a very easy way of doing this.

You can count calories, but let's be frank who has the time or inclination to do this? The trick is to use your hand. A portion should be the size of your fist or the size of your palm. A "fist" of steamed rice, a "palm" of fish, etc...

"Ok... but, WHAT do I eat?"

Avoid greasy/sugared foods, and keep in mind that your meals must contain 4 groups of food: Cereals, Dairy, Protein, Fruits & Vegetables. The less fat a food contains, the more calories are burn. This explains why some people can eat big amounts of food without gaining weight, instead of eating small portions of pizza, chocolate bars, or hamburguers.

For example, how about for meal #3: Salmon, brown rice and vegetables? Or maybe a turkey sandwich and vegetables? and for meal #4, some fruits with yoghurt? The combinations are endless.

Your body burns more calories when digesting foods high in fiber and protein, thus speeding the metabolism. And better yet, some foods like raw vegetables burn so much calories that they produce a negative caloric effect. This means that if you eat a 20 calory carrot, your body will burn 25 calories digesting it, making you burn 5 extra calories just for eating it.

Complex carbs (especially high fiber carbs like raw fruits, vegetables, and nuts) & Lean proteins (like white meat, fish and eggs) are 'highly thermongenic foods' meaning every time you eat complex carbs & lean proteins your body has to burn a lot of fat just to digest the protein and carbs you eat.

People who drink 3 servings of dairy (milk, cheese or yogurt) a day can lose more weight on a diet which do not. The secret seems to be the calcium in milk that can accelerate fat burning.

Myth #3. "Skip breakfast, it helps you lose weight."

The most important meal of the day is breakfast, through it the body gets the nutrients needed to burn calories efficiently over 24 hours. Are you starving through out the entire day, feeling anxious? You didn't eat enough breakfast. Besides the 5-meals-a-day rule, a good and balanced breakfast is a must, it helps you burn calories faster.

Breakfast helps you lose weight if you eat it less than 1 hour after waking up. Breakfast 2 hours after waking up doesn't work because you lose the effect of reducing appetite and speeding up the metabolism.

Commercial juice has a lot of sugar and of course a sweet sugared bread doesn't help much to speed up the metabolism and lose weight. Eat lots of protein and fiber, say tuna for protein and vegetables for fiber, but don't forget the carbs, so 1 or 2 slices of wheat bread should do. (This is just an example, you can eat more or less, depends on you.)

"Ok, got any more tips?"

Sure I do, here you go.

- Eat slowly and chew well. You eat fast and you won't dissolve the food properly, giving large chunks of unchewed food to your stomache, making it harder to digest wich will make your metabolism slower as a result. Constipation is also a symptom of not chewing properly.

- Proteins, carbs and fiber should be eaten together, while fruits are best absorbed alone.

- Like "hot" and spicy foods with lots of tabasco, curry and chile? Spicy foods cause higher energy expenditure because they generate heat, which accelerates the combustion energy and acts as a fat-burning agent during digestion. Just add a little pepper to your food and you're done. But don't push it, too much spicy food is hard on the stomach.

- Your last meal must be 2 or 3 hours before going to sleep. But a little yoghurt, protein bar or glass of milk right before sleep keeps the insuline levels steady and the digestive motor going.

-Vary your food, the body will get used to eating the same things and reduce the speed of the metabolism. Eat something greasy and high in sugar once in a while, just for the heck of it.

Step 3: Drinks

Myth #4. "Your body needs 2 liters/8 glasses of water everyday."

Mmm.. Yes and No.

In general, to remain healthy we need to take in enough water to replace the amount we lose daily through excretion, perspiration, and other bodily functions, but that amount can vary widely from person to person, based upon a variety of factors such as age, physical condition, activity level, and climate.

Scientists say there's no clear health benefit to chugging or even sipping water all day. So where does the standard advice of drinking eight glasses/2 liters each day come from? "Nobody really knows" says Dr. Stanley Goldfarb, a kidney expert at the University of Pennsylvania.

Now, some people say "If you feel thirsty, drink; if you don't feel thirsty, don't drink unless you want to." That's like saying "If you feel hungry, eat. Don't feel hungry, don't eat", but we already know that in order to keep our body and metabolism fully functional and healthy we need to eat 5 times a day even if we're not hungry, so why wait until we're thirsty? Remember the old saying "Dig the well before you're thirsty."

But like I said, everything in excess is bad for you, even water. Don't over do it or your kidneys will take the hit.

"Ok, so how much water should I drink?"

Depends on what you do. I excercise a lot, I also eat a lot, I'm young and active, and live in a warm-to-tropical area, so my water requirements are more than the average. I drink 2-2.5 liters a day.

But for the average working person, somewhere between 1-2 liters is enough, that's 4 to 8 glasses a day.

A clinical research center in Berlin found that after you drink 17 ounces of water, your metabolism increases fat burning by 30% within 10 minutes of taking water.

"Got it. Now, what to drink?"

Water is recommended, but you can also drink natural juices, coffee, tea, etc. I don't drink soft-drinks like coke or other kind of soda because of their high sugar contents, but If you like them, then be my guest. At least drink some natural water once in a while.

According to a study published by the American Journal of Clinical Nutrition, green tea helps you burn between 35 and 43% more calories per day.

"Can I drink water when I'm eating?"

Of course. In fact, the food "claims" for water, makes the consistency a lot softer for digestion. But don't get too excited, 1 or 2 glasses is fine, if you drink more, you will be making it harder for the stomach to digest the food since water reduces the acidity of the stomach.

Sometimes the brain confuses the thirsty signals with hungry signals, so the next time you feel hungry, have a drink.

- Something that's also interesting:

Most of the "facts" and "claims" of this lack-of-water seems to come from a book published by Dr. Batmanghelidj, an Iranian-born physician who now lives in the U.S. He maintains that people "need to learn they're not sick, only thirsty'' and that simply "drinking more water "cures many diseases. However, he arrived at his conclusions through reading, not research, and he claims that his ideas represent a "paradigm shift" that required him to self-publish his book lest his findings "be suppressed.''

Now, you need to know something. Since I started to go to the gym (November-2009), I've drinked 2 liters of water everyday, sometimes even more (2.5 liters). Since that time, I haven't got sick, not one day. Coincidence? Maybe, maybe it's the sum of all parts (Exercise, nutrituon and water), maybe it's just the water, just remember that nothing is impossible, and we're a long way to understanding everything in our world.

Step 4: Exercise

Myth #4. "Killing yourself in the gym EVERYDAY is the best way to accelerate your metabolism and lose weight."

If a person starts to exercise more, he/she will burn more calories not only by direct physical activity, but the fact that he/she is fitter and more active will also speed up the person's metabolism. The basal metabolism is also influenced by body composition, people with more muscle and less fat generally have a faster metabolic rate.

1 pound of muscle burns 5-14 calories per day, so when you form/grow 5 pounds of muscle your metabolism will burn extra 25-70 calories per day and lose 2 ½ to 7 pounds per year of extra fat.

Despite the loss of 2 ½ to 7 pounds of fat is not a lot, when you grow five pounds of muscle - you will be 5 to 10 pounds slimmer because muscle takes up space occupied by fat.

"So how much excercise should I do?"

Now, about the myth. It is best to do a session of high intensity exercise at least 3 times a week, and during the other days you can do low intensity exercise.

The more intense you exercise (weights for example), the more you will continue to burn calories "after" your workout is over, keeping you with a higher fat-burning metabolism during the day. Cardio excercises are a must too, do 20 to 40 minutes of eliptical, bicycle, etc.

This is for the "average" working person, a person who doesn't want to build muscle like a pro, just stay in shape.

The reason why people get fatter by the passing of the years, is because the body tends to lose muscle with the age, and thus the metabolism slows down.

Step 5: Other Factors

Food, drinking and exercise are not the only factors that contribute to the metabolism equation. Here are some diseases or disorders that can cause the metabolism to malfunction.

Hyperthyroidism. Hyperthyroidism is caused by an overactive thyroid gland. This gland secretes too much thyroxine, which speeds up the metabolism. It causes symptoms such as weight loss, rapid heart rate, blood pressure, protruding eyes and swelling in the neck caused by enlargement of the thyroid gland (goiter). This disease can be controlled by medication, surgery or radiotherapy.

Hypothyroidism. Hypothyroidism is a thyroid gland absent or poorly reactive and usually the result of a developmental problem or a disease that destroys the thyroid gland. This gland secretes an insufficient amount of thyroxine, which slows the metabolism. When left untreated hypothyroidism can cause brain and growth problems. Hypothyroidism slows body processes and causes fatigue, decreased heart rate, excessive weight gain and constipation. The young people that are diagnosed with this disorder can be treated with thyroid hormone administered orally (by mouth) to having a normal concentration of this hormone in the body.

Inborn errors of metabolism. Some metabolic diseases are inherited. These diseases are known as inborn errors of metabolism. Shortly after the birth of a baby, they do tests on many of these metabolic diseases. Inborn errors of metabolism can sometimes cause serious problems if not controlled through diet or medication from an early age.

If you eat properly and still have overweight or underweight problems, I would recommend to check your thyroids, just in case. Also, for a proper working of the thyroid gland, the thyroid gland needs no more than 70 micrograms/day of Iodine.

Natural sources of iodine include sea life, such as kelp and certain seafood, as well as plants grown on iodine-rich soil. Iodized salt is fortified with iodine. Check to see if your table salt says something about Iodine.

Step 6: Sleep Well

Sleep well. I can't stress this enough.

An average person needs from 8 to 10 hours of sleep everyday. Maybe 7, but that's pushing it. Sleep less than that and your metabolism won't function properly, you will gain fat, gain volume, and your efficiency will drop to the minimum.

A good 8 hours of sleep helps burn calories and build muscle, and thats 8 hours of deepcontinuous sleep.

When you don’t get enough sleep the levels of leptin in your body are lowered. Leptin is a blood protein that suppresses your appetite.

With your levels of leptin being lowered due to sleep depravation the levels of grehlin in your body are increased. Grehlin is a hormone that’s released in your body that makes you want to eat.

Step 7: Finishing

Well, I think that pretty much covers it. Remember, my goal wasn't weight loss or something like that, I just want you to be able to eat what you like as many times as you like with a faster healthier metabolism.

If weight loss and a healthier, more efficient body are byproducts of this, then we are some very lucky folks.

And remember, please BE CONSTANT. You don't get a fast metabolism overnight. Follow the guidelines and you should be ok.

I hope you liked this instructable and more importantly, I hope it helps you to get a happier and healthier life. Sorry if it was a lot to read =P. Take care of yourself and others!! All the best. =)

    It isn't true that starving won't lead to fat loss. If maintained long enough, starvation WILL lead to fat loss (for people with otherwise normal health). And long enough isn't that long either. 3-4 days top for most. Substantial caloric restriction for a few days, as long as there is little to no sugar (of any kind) consumed, will also result in the same. The way to tell for sure that you are burning fat is to get some keto sticks from the pharmacy, test your urine prior to starting fasting or starvation diet (at which point it should show no ketones, if you see ketones at this stage you probably have diabetes or something, go see the doctor), and every day thereafter (for me, about day 3 ketones start showing up, and will show up in large quantities thereafter -- my fat metabolism shuts down pretty quickly if I consume any quantity of carbs/sugar). As soon as your body runs out of glycogen and glucose reserve, it will start accessing fat. I am NOT recommending that anyone starve themselves, however if done right (part of "right" means lots of protein) it is possible to use fasting to increase ones metabolism. Look up literature on Intermittent Fasting.

    One more thing. Fat metabolism produces a lot of energy. If one can wade through 2-3 days of the low of fasting or starvation, subsequent weeks will be filled with lots of ridiculous amounts of energy and metal alertness unlike anything you have sen. You can actually work out far more in this state, thereby increasing the fat burn even further.

    There were some e-mail rumors that Coke was "stronger than your stomach acid" and "It's used by highway patrols to dissolve blood after an accident". Do you know if that's true? I didn't believe it, (I drink a Coke about every two weeks), I know that the sugar content isn't healthy, (it can't hurt every once in a while), but if that was true, -I still don't think it is- could it hurt?


    Reply 7 years ago on Step 3

    Thanks for your comment. It is true, police sometimes use coke (when they don't have the appropiate product in hand) to remove most blood in an accident. It is not true however, that coke is stronger that your stomach's acid. It is true that you can use coke to remove rust out of metals though. Coke and sodas in general carry a lot of problems and side effects, but probably the most dangerous is the sugar. 6 spoons of sugar is the maximum recommended for an adult. 1 can of coke has 15 spoons, and there's people that drink up to 3 cokes a day, you do the diabetic math. Does it hurt? Yes. Once a month? Hardly. Coke can be a very good ally when you have stomach illnesses. Take care and thanks for reading!


    Reply 7 years ago on Introduction

    coke is not good for illnesses unless you have low bloodpressure/fatigue. coke is stronger than your stomach acid, your info would be incorrect. i used to work at a bottling can company, they had to specialy chemicaly treat thier cans because the soda will eat away the aluminimum to put things in perspective. caffine raises your bloodpressure wich is bad esp if you have a fever or are sweating.


    8 years ago on Step 3

    I too stopped having frequent kidney infections when I DROPPED my water consumption from 2.5 liters a day to between 1.5 and 2. However, I've always been quite sick, so if drinking water was all it took to keep from getting ill, I think I'd be on easy street. So I will anecdotally refute the findings of that 'doctor' there. ;)

    I like your tips here. I might actually be able to STICK to a plan like this, one that allows me to have pizza once in awhile. ;)

    Thanks for posting!


    Reply 8 years ago on Step 3

    Great that you stopped that dumb rule of water before it was too late. Like I said, maybe the illness I haven't experienced it's the sum of all parts, or maybe it's just me :).

    Thanks for your comment!! I'm glad you liked it, take care! If you really want it, you can stick to it, to everything. :).

    Hi nice article.When to vary food every week or day


    Reply 9 years ago on Step 2

    Thanks! You should vary it whenever you feel like it, it's up to you, but don't eat the same things all week long, maybe 2 or 3 days in a row of the same things are fine, and one day a week you could eat a large piece of pizza if you like. Take care maovi!

    Nice Instructable mate!

    I also remember a period that I have lost something more than 25 pounds just by eating small but nutrient meals (about 3 to 4 a day) but exercising a lot.
    And that was in a period of 1 - 2 months.

    The bad thing is that I gained that weight over 3 years period due to no exercise...

    Exercising and eating regularly plus drinking 2 - 2.5L of water seemed to worked for me once.
    I'm also pushing this "diet" now and have lost almost 7 - 8 pounds...

    In the end what you say is correct, still everyone has to explore himself alone.

    Cheers mate!!!


    Reply 9 years ago on Step 7

    Thanks for your comment! You are right, "to each his own", this are only guidelines, I'm glad its working for you again, give it all the best!

    Thanks and take care!

    Dairy is a food group only because the senator from wisconson was on the original committee that created the food groups.


    Reply 9 years ago on Introduction

    It's a food group here in Canada and the "milk" people had nothing to do with it.


    Reply 9 years ago on Introduction

    Did Canada lead or follow? (1933 v. 1942)



    Reply 9 years ago on Introduction

    Really? Well I'm not from the US so this "food groups" are not US based. I wasn't really sure dairy was a food group, it's really on the same category as the Protein group but most people skip them because they think its bad for them. Having 2 or 3 glasses of milk everyday helps you speed up your metabolism and lose some weight as well.


    Reply 9 years ago on Introduction

    Especially since most people can't digest parts of it-it acts as 'filler' without much nutrient value. It's not going to speed up your metabolism-unless you are lactose intolerant (as many adults become) and you consider diarrhea a good way to loose weight.


    Reply 9 years ago on Introduction

    People who drink 3 servings of dairy (milk, cheese or yogurt) a day can lose more weight on a diet which do not. The secret seems to be the calcium in milk that can accelerate fat burning. People can even drink skimmed of lowfat milk but if they are lactose intolerant then it is out of the question. It's obvious they can skip that part.

    Ah, you saw it on a website that is selling stuff. Good primary source, after all, just because they are selling it means that they have to tell the truth and wouldn't lie just to get your money, right?
