Do Calories Matter? – Part 4

We’re on to PART 4! This is the longest series of blog posts I’ve ever done. Evidently, there is a lot more to talk about! These are just the highlights of a much bigger picture.


Let’s do a quick recap379302_325658287555375_1376847731_n.21

The flaws of the calorie centric view:

  • Humans are not perfect machines (cannot apply the concept of calories in/calories out). Equations are pretty much useless. Just use it as a GUIDE. Your life does not depend on it!
  • It goes against the Second Law of Thermodynamics
  • Calorie counting does not take into account the quality of foods and its metabolic effects on hunger, appetite, energy usage/storage, satiety etc
  • Many factors affect metabolism – environment, genetics etc
  • It is possible to increase fatness on a reduced calorie diet (on high GI foods) [1] SURPRISE SURPRISE!
  • Quality of diet can affect/induce anabolism (fat storage)
 Quick links to Part 1, 2 and 3!

QUALITY over QUANTITY

A calorie focussed mind would lookout for foods that are low/-er in calories. Since FAT is calorie dense, it immediately gets a bad rep. Low fat foods are usually high in refined carbs/starches. That’s because most times, when you take something out, you need to fill it with something else!
Even if they are not “empty calories” per se (containing vitamins, minerals, fibre, antioxidants etc), these foods that are high in processed, artificial refined carbs/starches are DETRIMENTAL to health, causing harm to the body and metabolic dysfunction [2].
What to eat?
NUTRITION over CALORIES
 Tips-How-to-Pick-Good-Dog-Food-Ingredients-Dog-Food
Low refined sugar/carbs/starches
If you are going to eat carbs, go for WHOLE minimally processed ones. Starchy vege (sweet potatoes, potatoes, taro, pumpkin, squash etc) and fruits are great options. When going for rice/pasta/bread, think brown/red/wild/black. These are more nutrient dense. Refined options have been stripped of their vitamins, minerals and fibre. You’re basically just eating sugar.
Fats
The only bad fat here is highly processed trans fat. Go for fats found naturally in olive oil, avocado, nuts, seeds, dairy products, real butter, fat from meat and fish. These are all high in a good combination of mono- and polyunsaturated fats.

Protein
Meat, fish, eggs and dairy products (milk, cheese, yoghurt).2016-10-21-1477056674-8700239-homer
How much of each macronutrient (carbs, protein, fat) to eat is different for each individual. Get a dietitian to do the work. ;D

Gut Health

This is a growing area of research. The little bacteria in your gut is SO important!
Research has now shown that WHAT you eat affects the little bacteria world in your gut. You might need to rethink your zero-calorie artificial sweeteners! They have been shown to have the potential to alter your gut microbiome [3]. ANY disruption to this balance can possibly lead to obesity, diabetes, cancer, inflammation, inflammatory bowel disease and a decreased immune system [4].stomach-bacteria
The quality of food, prebiotics (food for healthy gut bacteria), probiotics (healthy gut bacteria) and antibiotics affect the overall balance of gut bacteria.
Sources of prebiotics: Prebiotics are the fibre foods that cannot be digested. Onions, garlic, asparagus, unripe bananas, artichokes are great sources. These are “eaten” and considered food for your gut bacteria.
Sources of probiotics: Fermented foods like yoghurts, kefir, tempeh, miso, kombucha, saukraut etc. Different brands use different strains of bacteria and the amount it contains varies.

These are beneficial but there is very little research that shows how much pre/probiotics to consume, exactly which strain (is best), the quality and how much of it actually stays in our gut after consumption [5].

Physical Activity

I don’t think I need to elaborate on this one.Processed with VSCO with f2 preset
JUST GET UP AND GET MOVING!
Any form of physical activity is better than NOTHING. Pick something that you like and JUST DO IT!

Rest
Sleep has become a luxury and stress has now become commonplace in our lives.
How do these affect weight and metabolism?
Stress stimulates the body to release cortisol, which is the hormone involved in CRAVINGS. “Stress eating” is real.Processed with Snapseed.
When you don’t get enough sleep, the hunger hormone kicks in.
Together, they have an influence on food intake and fat storage.


When you focus on QUALITY and pay attention to your natural body cues, you wouldn’t need to be whipping out your calculator and counting everything.

 Key points to remember:

-Focus on the SOURCE of calories and not calorie counts

-Eat REAL, MINIMALLY processed, WHOLE, FRESH, NUTRIENT dense foods

The GOLDEN rule is: If it is packaged, highly processed with ingredients that you can barely pronounce with loud “health claims”, don’t buy it!

-Achieving optimum hormonal balance and metabolic function is KEY

Do Calories Matter? – Part 3

Hello Part 3 (Part 1 and Part 2)!

We’ve explored calories, energy in food, the calorie focused theory and how we gain weight!

Now, let’s take a look at what happens if we just ate less!


Undereating

Image result for undereating

The conventional approach to lose weight would be to decrease food intake, increase physical activity or BOTH! Because……

Calories in < Calories out = WEIGHT LOSS

It seems to make sense.

We’ve all done it at some point in our lives. And I can tell you that it definitely works!

……tired-runner

Until your body catches up and starts going against you. You can’t outsmart your body!

Your body will undergo a period of trying to adapt to the decreased food intake and/or increased physical activity. It wants to defend your body’s set weight [1]. This leads to biochemical changes that can throw off your metabolism (i.e. slowing it down!).

You become very efficient at using your fuel and stores – being able to survive with less energy. It means that overall, you burn less. Keep in mind that your basal metabolic rate takes up a huge chunk of your daily expenditure (60-75%!). You do not want to mess this up.

The pitfalls of undereating

If this continues, you might:

-Hit a plateau

-Feel tired and fatigued

-Experience mood/behavioural changes

Hunger

-Strong cravings

Lose muscle

-Store more fat

Gain weight

tired

…… basically a ticking time bomb towards failure and losing control. And all of this is happening because your body is trying to look out for you!

This potentially explains why some people, despite a calorie deficit, fail to lose weight!

There’s evidence that fatness can increase despite being in an energy deficit state [1].


We’ve seen how the calorie focused view fails to explain weight gain and weight loss.

So, now what?

What CAN we do?

Stay tuned for Part 4!

Do Calories Matter? – Part 1

Hey Hey Hey!

How have you guys been?

Can you believe that we are halfway through the month of MAY?!


I just want to take a moment to say THANK YOU for following/reading my blog. Especially to those that have been around since I started blogging!

To me, the numbers don’t matter. As long as I am able to make a small difference/influence somewhere, ALL my effort is worth it.

I will try to blog more often, so do subscribe to my blog to receive the LATEST (and the greatest. Baahahhahhaha! #jokes) stuff in your mailbox! *The subscription tab is on the top right corner*


Quick life update:

DONE with clinical placement! YASSSSS!IMG_2513

I’m currently on community placement (Masters of Nutrition and Dietetics) with my classmate, Tegan. So far, we’ve been creating content for eNews, tip sheets and updating the food database.

During our first 2 weeks, we worked on a presentation – “The Calorie Controversy” – for our supervisor to present at FILEX 2017 (An educational conference by the world’s leading health and fitness experts!).

Let’s just say we found some pretty compelling stuff. I will be sharing glimpses of what we found. 😉


It will be a series of several blog posts under the title “Do Calories Matter?”

Counting calories? Calories in = Calories out?Image result for counting calories

For this post, we will look at what a calorie is.


Before we even begin talking about whether or not calories matter, WHAT exactly is a calorie? What does the body use energy for?

Calorie and Joule

A calorie is the amount of energy that is needed to raise the temp of 1 Kg of water by 1 degree at room temp.

Joule is the SI unit of energy. It is the work that is needed to move 1 Kg of an object with a force of 1 Newton by 1 metre in the direction of the force.

Fun fact: The zettajoule (ZJ) is equal to one sextillion (1021) joules. A yottajoule (YJ) is equal to one septillion (1024) joules. Just thought that sounded pretty cool.

Ok, enough of the JOULE. I’m a calorie person. Here’s the conversion:

1 kcal = 4.182 kJ

*Both units commonly used to represent ENERGY in food*

How do we know how much energy is in food?

Image result for bomb calorimeter

By using the bomb calorimeter. Food is basically torched and the heat produced represents the energy content.

Food provides energy and nutrients. But where does it all go?

Image result for daily energy expenditure

Source

Our bodies need energy to do all of the above (image).

Basal metabolic rate: Energy needed to keep you alive at REST *Note that this is a huge chunk of your daily energy expenditure (60-75%!)*

Thermic effect of food: Energy needed to digest food

NEAT: Movement that is not exercise: fidgeting, cooking, going to the car etc

Activity: Physical activity: Running, swimming etc

What is it in food that provides energy?

Carbohydrate 1g = 4 kcal

Protein 1g = 4 kcal

Fat 1g = 9 kcal

Alcohol 1g = 7 kcal

How much energy or how many calories do we need?

That depends. Everyone is different. You can work it out here. But there are many things that can influence this (genetics, weight, height, body composition, health, hormones etc). Even activity levels are highly variable. We cannot truly be sure how much we really need. But of course, it gives you a rough estimate.


Now we know what a calorie is and what our bodies use the energy for!

The burning question is: Do calories REALLY matter?

Stay tuned for WHY weight gain is not simply calories in > calories out or why weight loss is not just calories in < calories out!
