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.

10 Real Reasons Why Breaking Bad Habits Is So Difficult

10 Real Reasons Why Breaking Bad Habits Is So Difficult

Bad habits expose us to suffering that is entirely avoidable. Unfortunately, these bad habits are difficult to break because they are 100% dependent on our mental and emotional state.

Anything we do that can prove harmful to us is a bad habit – drinking, drugs, smoking, procrastination, poor communication are all examples of bad habits. These habits have negative effects on our physical, mental and emotional health.

Humans are hardwired to respond to stimuli and to expect a consequence of any action. This is how habits are acquired: the brain expects to be rewarded a certain way under certain circumstances. How you initially responded to certain stimuli is how your brain will always remind you to behave when the same stimuli are experienced.

If you visited the bar close to your office with colleagues every Friday, your brain will learn to send you a signal to stop there even when you are alone and eventually not just on Fridays. It will expect the reward of a drink after work every day, which can potentially lead to a drinking problem.

Kicking negative behavior patterns and steering clear of them requires a lot of willpower and there are many reasons why breaking bad habits is so difficult.

1. Lack of Awareness or Acceptance

Breaking a bad habit is not possible if the person who has it is not aware that it is a bad one.

Many people will not realize that their communication skills are poor or that their procrastination is affecting them negatively, or even that the drink they had as a nightcap has now increased to three.

Awareness brings acceptance. Unless a person realizes on their own that a habit is bad, or someone manages to convince them of the same, there is very little chance of the habit being kicked.

2. No Motivation

Going through a divorce, not being able to cope with academics and falling into debt are instances that can bring a profound sense of failure with them. A person going through these times can fall into a cycle of negative thinking where the world is against them and nothing they can do will ever help, so they stop trying altogether.

This give-up attitude is a bad habit that just keeps coming around. Being in debt could make you feel like you are failing at maintaining your home, family and life in general.

3. Underlying Psychological Conditions

Psychological conditions such as depression and ADD can make it difficult to break bad habits.

A depressed person may find it difficult to summon the energy to cook a healthy meal, resulting in food being ordered in or consumption of packaged foods. This could lead to eventually become a habit that adversely affects health and is difficult to overcome.

A person with ADD may start to clean their house but get distracted soon after, leaving the task incomplete, eventually leading to a state where it is acceptable to live in a house that is untidy and dirty.

The fear of missing out (FOMO) is very real to some people. Obsessively checking their social media and news sources, they may believe that not knowing of something as soon as it is published can be catastrophic to their social standing.

4. Bad Habits Make Us Feel Good

One of the reasons it is difficult to break habits is that a lot of them make us feel good.[1]

We’ve all been there – the craving for a tub of ice cream after a breakup or a casual drag on a joint, never to be repeated until we miss how good it made us feel. We succumb to the craving for the pleasure felt while indulging in it, cementing it as a habit even while we are aware it isn’t good for us.

Over-eating is a very common bad habit. Just another pack of crisps, a couple of candies, a large soda… none of these are needed by us. We want them because they give us comfort. They’re familiar, they taste good and we don’t even notice when we progress from just one extra slice of pizza to four.

5. Upward Comparisons

Comparisons are a bad habit that many of us have been exposed to since we were children. Parents might have compared us to siblings, teachers may have compared us to classmates, and bosses could compare us to past and present employees.

The people who have developed the bad habit of comparing themselves to others have been given incorrect yardsticks for measurement from the start.

These people will always find it difficult to break out of this bad habit because there will always be someone who has it better than they do: a better house, better car, better job, higher income and so on.

6. No Alternative

This is a real and valid reason why bad habits are hard to break. These habits could fulfill a need that may not be met any other way.

Someone who has physical or psychological limitations such as a disability or social anxiety may find it hard to quit obsessive content consumption for better habits.

Alternately, a perfectly healthy person may be unable to quit smoking because alternates are just not working out.

Similarly, a person who bites their nails when anxious may be unable to relieve stress in any other socially accepted manner.

7. Stress

As mentioned above, anything that stresses us out can lead to adopting and cementing bad habits.

Advertising

When a person is stressed about something, it is easy to give in to a bad habit because the mental resources required to fight them are not available.

Stress plays such a huge role in this that we commonly find a person who had previously managed to kick a bad habit fall back into the old ways because they felt their stress couldn’t be managed any other way.

8. Sense of Failure

People looking to kick bad habits may feel a strong sense of failure because it’s just that difficult.

Dropping a bad habit usually means changes in lifestyle that people may be unwilling to make, or these changes might not be easy to make in spite of the will to make them.

Over-eaters need to empty their house of unhealthy food, resist the urge to order in and not pick up their standard grocery items from the store.

Those who drink too much need to avoid the bars or even people who drink often.

If such people slip even once with a glass of wine or a smoke or a bag of chips, they tend to be excessively harsh on themselves and feel like failures.

9. The Need to Be All-New

People who are looking to break bad habits feel they need to re-create themselves in order to break themselves of their bad habits, while the truth is the complete opposite.

These people actually need to go back to who they were before they developed the bad habit.

Advertising

10. Force of Habit

Humans are creatures of habit and having familiar, comforting outcomes for daily triggers helps us maintain a sense of balance in our lives.

Consider people who are used to lighting up a cigarette every time they talk on the phone or munching on crisps when watching TV. They will always associate a phone call with a puff on the cigarette and screen time with eating.

These habits, though bad, are a source of comfort to them as is meeting with those people they indulge in these bad habits with.

Final Thoughts

These are the main reasons why bad habits may be difficult to break but it is important to remember that the task is not impossible.

Do you have bad habits you want to kick? My article How to Break a Bad Habit (and Replace It With a Good One) gives you tips on well, how to kick bad habits while my other article How Long Does It Take to Break a Habit? Science Will Tell You gives realistic information on what to expect while you’re trying to quit them.

There are many compassionate, positive and self-loving techniques to kick bad habits. The internet is rich in information regarding bad habits, their effects and how to overcome them, while professional help is always available for those who feel they need it.
