Expert Advice That Will Teach You How to Increase Your Metabolism

Expert Advice That Will Teach You How to Increase Your Metabolism

Wouldn’t you like to be able to eat twice as much as you do now without gaining weight? If so, I have good news for you because this is possible when you learn how to increase metabolism.

How Much Do You Know About Metabolism?

Before we get to the meat, let me say that metabolism is a term that describes all the chemical reactions in your body.[1] These chemical reactions keep your body alive and functioning, however, the word metabolism is often used interchangeably with the metabolic rate or the number of calories you burn.

The metabolic rate is a rough estimate of how much energy your body needs to simply stay alive and perform all its biochemical reactions. These reactions require energy, aka burn calories.

Imagine that your brain alone consumes nearly 20% of your TDEE (total daily energy expenditure at rest),[2] your digestion and the detoxifying system come second, repairing tissues third and so on.

Staying alive is expensive for your body and its two main currencies are fats and sugars.

When I am talking about improving your metabolic rate (metabolism), I mean improving the amount of energy, your body requires to (pretty much) lay down in bed and do nothing for 24 hours.

Extra physical activity, extra thinking or fighting illness are things that require a lot of energy (burn a lot of calories) but they don’t really increase metabolism… actually they can decrease it.

Can You Naturally Change the Speed of Your Basal Metabolism?

The answer to this question is yes and you can also achieve an increase in metabolism and a drop in body fat by eating more.

Shocked? Well, I was too.

The way I came across this phenomenon is quite funny. Over my 10 years as a coach, I helped many busy professionals to naturally increase their metabolism by getting them leaner, fitter and stronger but, at the beginning of my career, I actually had no idea whether they were losing weight because of an increase in metabolism or because we created a calorie deficit with diet and exercise.

When I was training my clients regularly, they would lose weight. Every time I would take a few weeks of vacation, I would come back to London and find out that most of them gained back a generous amount of weight despite the fact that they were following their diet and they swapped our weight training sessions with cardio.

On the contrary, when they were going on vacation, they would do zero exercises and binge like there was no tomorrow but come back either lighter or weighing the same (but looking more muscular).

Observing this phenomenon happening over and over again, got me curious about the mechanics of our metabolism and the ways to hack it.

Was it really possible that by relaxing and eating more food, someone could actually maintain his/her current weight or even be losing fat?

Driven by the desire to answer this question, I spent a good amount of years researching and testing different food strategies until I finally cracked the code to an improved metabolism that allows you to eat like a king and look like a Greek God.

Does Eating More Increase Metabolism?

Before I explain why eating more increases your metabolism, let me dig into something that I see people doing much more often: “eating less and moving more.”

It is quite common to see people embarking their yearly weight loss journey (usually after Christmas or Easter) by following very restrictive diets and bombarding their body with several hours of exercise per day.

Despite the short-term effectiveness of this approach, in the long run, if the goal is to increase metabolism and lose a lot of fat over an extended period of time, this simply won’t work.

As I have mentioned before, eating fewer calories and exercising more are energy-consuming activities for your body. In the first case, your body needs to use its own energy reserves to top up the missing energy it needs to fully function; and in the second, it takes your body extra energy to contract your muscles.

In both cases, your TDEE (Total daily energy expenditure at rest) doesn’t vary much; therefore your metabolism stays unchanged.[3]

A different scenario happens when you eat less and move more for an extended period of time (weeks or months). In that case, your metabolism will slow down because your body is receiving a “we have little access to food and we need to run away from threats” signal.

Your metabolism is like your bank account.

To understand this concept, let’s imagine that you have $4,000 coming into your bank account each and every month. The money you spend on housing, transport, food and leisure are calibrated according to this monthly income.

Now, imagine that a rich uncle starts to send you $1,000 each day. What would you do? Probably, you would save that money for the first two or three days but, when you notice that $1,000 keep on coming every single day, you would likely start to spend more right?

What if, instead of a rich uncle sending you money, a poor uncle needed your financial help to pay for the treatments of his illness? You would probably try your best to adjust your spending according to your old $4,000 monthly budget.

That’s exactly how your body reasons:

More Resources Coming in = More Energy Released (Improved Metabolism)

Fewer Resources Coming in = Less Energy Released (Decreased Metabolism)

Note that activities like weight training[4] and high-intensity interval training (HIIT),[5] when combined with an increase in nutrient-rich foods, will also improve your metabolism.

For this reason, today, when I coach a new client, I always start by increasing their daily food intake and their physical activities. Usually, people are quite confused because they come to me to lose weight and I tell them to eat more but, without fail, the next weekly weight-check shows a lower number.

Be aware that not all foods are equal and only certain foods have the power to increase metabolism to a noticeable extent.

Foods That Increase Metabolism

Doubling up on Snickers bars won’t improve your metabolism and you know that. What you may not know is that certain foods that are marked as “healthy” doesn’t help you with increasing your metabolism. They also make you gain weight.

Before giving you a list of foods to eat or avoid, let me explain a simple principle of human biochemistry.

Your body uses energy from three (or four) main sources:

  • Sugars: whether you eat a Snickers bar or a banana, the carbohydrates contained in both get absorbed in the gut and become blood glucose (the basic form of sugar our body utilizes as a source of energy).[6]
    When blood glucose is present in the bloodstream (elevated levels), the body always uses it as its primary source of energy. When blood glucose levels drop (this phenomenon happens when you’re using these sugars to fuel a physical activity or when your pancreas produced a spike of insulin and stores that glucose into fat and muscles), your body starts to release fatty acids into the bloodstream to use as a source of energy.
  • Fatty acids: either from your own fat cells (adipocytes) or from whatever fat-containing foods you ate in the past 2-3 hours. Fatty acids are a slower and more consistent form of energy than sugars that your body can utilise.
  • Amino acids: Amino acids are the broken-down form of proteins. Proteins cannot be used by the body as a source of energy, not even in their broken-down form. Your body can transform amino acids into glucose with a process called gluconeogenesis.[7] This is a very inefficient process where a decent amount of energy gets wasted (and that’s a good thing for us but I’ll get to that later).
  • Ketones: when you don’t feed your body any source of carbs (or proteins in excess), your liver produces an alternative source of energy called Ketones. It can replace the need for glucose (most of it at least).[8]

Now that you know the four energy sources the body can use to fuel its metabolism, let’s get to the meat (quite literally).

To make this simple for you, I am going to divide foods into three categories:

Advertising

  1. Red Flags – Avoid the red foods because they slow your metabolism. They are usually extremely low in micronutrients and high in antinutrients (agents that are highly toxic). They are highly processed or spike your insulin levels (therefore stopping your fat burning process).
  2. Orange Foods – Limit your consumption of orange foods. The orange foods on the list are suboptimal choices but they don’t have a negative impact on your metabolism when consumed in moderation. In fact, they contain a decent amount of micronutrients and, if eaten in small amounts, they shouldn’t stop your fat burning process.
  3. Green Foods – These are foods to consume most. Green foods will improve your metabolism and should be the main bulk of your diet.

Next, I’ll get into details exactly what foods to eat and avoid:

Sugars and Carbs

Sugars do not directly improve metabolism because they stop the process of fat utilisation. There is an exception to this rule though. When you eat a diet extremely low in carbohydrates and sugars for an extended period of time (two to six days onwards), introducing carbohydrates and sugars can actually improve metabolism quite a bit.

Unfortunately, for most of us that love eating bread, pasta, fruit and yoghurt, unless we were on a low-carb diet for the past few days, these foods are not an optimal choice.

Sugars like fructose (found in fruit or commercial sugar) actually decrease metabolism and should be limited. Heavily processed sugars and carbohydrates should be also limited. Here is the colour list of sugars and carbs that affect metabolism:

Red Flag Sugary Foods You Should Avoid:
  • Dried fruit
  • Commercial and packaged corn
  • High fructose corn syrup
  • All sorts of candies and lookalike
  • Packaged fruit juices and purees
  • Sugary dairy products like flavoured yoghurt, condensed milk etc
Orange Sugary Foods You Should Limit:
  • Bread and flour-based products
  • Milk and also vegan milk alternatives that are sweetened
  • Most fruit (exceptions are in the green list below)
  • Potatoes and potato starch products
  • Oatmeals and other grains
Green Sugary and Carb-Containing Foods That Improve Metabolism
  • All berries except strawberries
  • Tubers like squash, carrots, parsnips etc
  • Sweet potatoes
  • White rice
  • All green vegetables

Fats

Fatty acids and fats, in general, can improve or decrease metabolism depending on their composition.

Red Flag Fatty Foods You Should Avoid:
  • Margarine and hydrogenated fat
  • Lard
  • Gmo oils
  • Most vegetable oils from seeds and peanut oil
Orange Fatty Foods You Should Limit:
  • Nuts
  • Meat fat
  • Nut oils (macadamia, almond, cashew etc..)
  • Seeds
Green Fatty Foods You Should Eat Daily
  • Extra virgin olive oil (non-heated)
  • Avocado
  • Coconut oil
  • Butter (organic)
  • Egg yolks (free-range)
  • Bone marrow

The fatty foods in the green section tend to be very effective in increasing metabolism, especially in the absence of carbohydrates because they stimulate the production of ketones (I’ll talk about this later).

Bear in mind that 1 gram of fat has 2.5 times the calories of a gram of protein or carbohydrates; therefore “eating more fats” to increase metabolism should be done very gradually to avoid weight gain.

Proteins

Eating food not only sends regulatory signals to your brain about abundance vs scarcity of resources, but it can also increase your metabolism for a few hours. This is called the thermic effect of food (TEF).[9] It’s caused by the extra calories required to digest, absorb and process the nutrients in your meal.

Protein causes the largest rise in TEF.[10] It increases your metabolic rate by 15-30%, compared to 5-10% for carbs and 0-3% for fats

Eating protein has also been shown to help you feel more full and prevent you from overeating, in fact, a study found that people were likely to eat around 441 fewer calories per day when protein made up 30% of their diet.[11]

Also, proteins help preserve muscle mass.[12] The more muscle mass we have, the higher our basal metabolism is.

For these reasons, the first nutritional advice I usually give to clients is to reduce sugars and increase proteins. This quick swap is often enough to kickstart their metabolism and commence the fat burning process.

Red Protein Sources That Should Be Avoided
  • Cheap whey proteins
  • Soy proteins
  • GMO meat
  • GMO eggs
  • Packaged meat
Orange Protein Source to Be Limited
  • Canned tuna
  • Canned fish
  • Canned meat
  • Gluten-rich products like Seitan
  • Farmed fish
Green Protein Sources to Have Daily
  • Free-range meat
  • Free-range eggs
  • Wild meat and fish
  • Whey protein isolate
  • Collagen and beef protein hydrolyzed

Note that this is a general categorisation of the foods that, when added to your diet, have the power to increase or decrease metabolism. There are some specific foods and supplements worth mentioning because they have been proven to improve metabolism by increasing thyroid output or resting heart rate, they are as follows.

Other Foods and Supplements

Cold water

Drinking water may temporarily speed up your metabolism. Studies have shown that drinking 17 ounces (0.5 litres) of water increases resting metabolism by 10-30% for about an hour.[13]

This is not a surprise since our body is made up mainly by water and proper hydration is key to a fast metabolism. This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it up to body temperature.

MCT Oils or Powders

Medium-chain triglycerides or MCT have been shown to improve metabolism by stimulating Ketone production.[14] Coconut oil contains MCT fats and, when used as a replacement for cooking oil can help you improve metabolism.

You can buy the concentrated version of MCT oils and eat it separately to further enhance this effect. Either way, coconut oil or pure MCT oil can be a great addition to your diet if you’re following a ketogenic or intermittent fasting protocol.

Caffeine

Caffeine and coffee have been shown to improve metabolism by improving heart rate and, therefore improving calorie consumption.[15]

Green Tea

Green tea

is thought to increase energy expenditure and fat oxidation, and to reduce fat production and absorption.[16]

Bottom Line

In this article, I just covered the basics of food and metabolism but, there are many other non-food related things you can do to improve your metabolism, like improving your sleep quality and following certain exercise routines.

For now, just know that making small and gradual changes to your diet can increase your metabolism and improve your general health. Starting from changing one habit at a time is always the best strategy to accomplish any goal.

Once you improve your diet, your hydration and your supplementation you can think about testing more advanced “bio-hacks” or techniques like ice baths and fasted HIIT training.

And remember, having a higher metabolism doesn’t only help you lose weight and keep it off but it also give you more energy and a feeling of vibrancy. If you give it time, it really is worth the investment.

The 10 Essential Habits of Positive People

The 10 Essential Habits of Positive People

Are you waiting for life events to turn out the way you want so that you can feel more positive about your life? Do you find yourself having pre-conditions to your sense of well-being, thinking that certain things must happen for you to be happier? Do you think there is no way that your life stresses can make you anything other than “stressed out” and that other people just don’t understand?  If your answer is “yes” to any of these questions, you might find yourself lingering in the land of negativity for too long!

The following are some tips to keep positive no matter what comes your way. This post will help you stop looking for what psychologists call “positivity” in all the wrong places!  Here are the ten essential habits of positive people.

1. Positive people don’t confuse quitting with letting go.

Instead of hanging on to ideas, beliefs, and even people that are no longer healthy for them, they trust their judgement to let go of negative forces in their lives.  Especially in terms of relationships, they subscribe to The Relationship Prayer which goes:

 I will grant myself the ability to trust the healthy people in my life … 

To set limits with, or let go of, the negative ones … 

And to have the wisdom to know the DIFFERENCE!

 2.  Positive people don’t just have a good day – they make a good day.

Waiting, hoping and wishing seldom have a place in the vocabulary of positive individuals. Rather, they use strong words that are pro-active and not reactive. Passivity leads to a lack of involvement, while positive people get very involved in constructing their lives. They work to make changes to feel better in tough times rather than wish their feelings away.

3. For the positive person, the past stays in the past.

Good and bad memories alike stay where they belong – in the past where they happened. They don’t spend much time pining for the good ol’ days because they are too busy making new memories now. The negative pulls from the past are used not for self-flagellation or unproductive regret, but rather productive regret where they use lessons learned as stepping stones towards a better future.

4. Show me a positive person and I can show you a grateful person.

The most positive people are the most grateful people.  They do not focus on the potholes of their lives.  They focus on the pot of gold that awaits them every day, with new smells, sights, feelings and experiences.  They see life as a treasure chest full of wonder.

5. Rather than being stuck in their limitations, positive people are energized by their possibilities.

Optimistic people focus on what they can do, not what they can’t do.  They are not fooled to think that there is a perfect solution to every problem, and are confident that there are many solutions and possibilities.  They are not afraid to attempt new solutions to old problems, rather than spin their wheels expecting things to be different this time.  They refuse to be like Charlie Brown expecting that this time Lucy will not pull the football from him!

6. Positive people do not let their fears interfere with their lives!

Positive people have observed that those who are defined and pulled back by their fears never really truly live a full life. While proceeding with appropriate caution, they do not let fear keep them from trying new things. They realize that even failures are necessary steps for a successful life. They have confidence that they can get back up when they are knocked down by life events or their own mistakes, due to a strong belief in their personal resilience.

7. Positive people smile a lot!

When you feel positive on the inside it is like you are smiling from within, and these smiles are contagious. Furthermore, the more others are with positive people, the more they tend to smile too! They see the lightness in life, and have a sense of humor even when it is about themselves. Positive people have a high degree of self-respect, but refuse to take themselves too seriously!

8. People who are positive are great communicators.

They realize that assertive, confident communication is the only way to connect with others in everyday life.  They avoid judgmental, angry interchanges, and do not let someone else’s blow up give them a reason to react in kind. Rather, they express themselves with tact and finesse.  They also refuse to be non-assertive and let people push them around. They refuse to own problems that belong to someone else.

9. Positive people realize that if you live long enough, there are times for great pain and sadness.

One of the most common misperceptions about positive people is that to be positive, you must always be happy. This can not be further from the truth. Anyone who has any depth at all is certainly not happy all the time.  Being sad, angry, disappointed are all essential emotions in life. How else would you ever develop empathy for others if you lived a life of denial and shallow emotions? Positive people do not run from the gamut of emotions, and accept that part of the healing process is to allow themselves to experience all types of feelings, not only the happy ones. A positive person always holds the hope that there is light at the end of the darkness.  

10. Positive person are empowered people – they refuse to blame others and are not victims in life.

Positive people seek the help and support of others who are supportive and safe.They limit interactions with those who are toxic in any manner, even if it comes to legal action and physical estrangement such as in the case of abuse. They have identified their own basic human rights, and they respect themselves too much to play the part of a victim. There is no place for holding grudges with a positive mindset. Forgiveness helps positive people become better, not bitter.

How about you?  How many habits of positive people do you personally find in yourself?  If you lack even a few of these 10 essential habits, you might find that the expected treasure at the end of the rainbow was not all that it was cracked up to be. How could it — if you keep on bringing a negative attitude around?

I wish you well in keeping positive, because as we all know, there is certainly nothing positive about being negative!
