Coffee is one of those things - you either love it or hate it. You know if you like the taste or not (or if it’s just a reason to drink sugar and cream). You know how it makes you feel (i.e. your gut, your mind, etc.).
Not to mention the crazy headlines that say coffee is great, and the next day you should avoid it!
There is actual science behind why different people react differently to it. It's a matter of your genetics and how much coffee you're used to drinking.
NOTE: Coffee does not equal caffeine. Coffee contains between 50-400 mg of caffeine/cup, averaging around 100 mg/cup. Coffee is one of the most popular ways to consume this stimulant. But… a cup of coffee contains a lot of things over and above the caffeine. Not just water, but antioxidants, and hundreds of other compounds. These are the reasons drinking a cup of coffee is not the same as taking a caffeine pill. And decaffeinated coffee has a lot less caffeine; but, it still contains some.
Let's look at caffeine metabolism, its effects on the mind and body, and whether coffee drinkers have higher or lower risks of disease. Then I’ll give you some things to consider when deciding if coffee is for you or not.
Not all people metabolize caffeine at the same speed. How fast you metabolize caffeine will impact how you’re affected by the caffeine. In fact, caffeine metabolism can be up to 40x faster in some people than others.
About half of us are “slow” metabolizers of caffeine. We can get jitters, heart palpitations, and feel "wired" for up to 9 hours after having a coffee. The other half is "fast" metabolizers of caffeine. They get energy and increased alertness and are back to normal a few hours later.
This is part of the reason those headlines contradict each other so much - because we’re all different!
The effects of coffee (and caffeine) on the mind and body
NOTE: Most studies look at caffeinated coffee, not decaf.
The effects of coffee (and caffeine) on the mind and body also differ between people; this is partly from the metabolism I mentioned. But it also has to do with your body’s amazing ability to adapt (read: become more tolerant) to long-term caffeine use. Many people who start drinking coffee feel the effects a lot more than people who have coffee every day.
Here’s a list of these effects (that usually decrease with long-term use):
So, while some of these effects are good and some aren’t, you need to see how they affect you and decide if it’s worth it or not.
Coffee and health risks
There are a ton of studies on the health effects of coffee, and whether coffee drinkers are more or less likely to get certain conditions.
Here’s a quick summary of what coffee can lead to:
Many of the health benefits exist even for decaf coffee (except the caffeine addiction and sleep issues).
NOTE: What’s super-important to note here is that coffee intake is just one of many, many factors that can affect your risks for these diseases. Please never think regular coffee intake is the one thing that can help you overcome these risks. You are health-conscious and know that eating a nutrient-rich whole foods diet, reducing stress, and getting enough sleep and exercise are all critical things to consider for your disease risk. It’s not just about the coffee.
Should you drink coffee or not?
There are a few things to consider when deciding whether you should drink coffee. No one food or drink will make or break your long-term health.
Caffeinated coffee is not recommended for:
If none of these apply, then monitor how your body reacts when you have coffee. Does it:
Depending on how your body reacts, decide whether these reactions are worth it to you. If you’re not sure, I recommend eliminating it for a while and see the difference.

Oh my gosh – nutrition and diet info is everywhere!
And each expert and association tries to lead you in their direction because they know best and their advice is going to help you. Right?
Everyone has heard (and maybe lived through) the intense focus on how much you eat. This has gotten way too much attention because while this does affect your weight and energy level, it's certainly not the “holy grail” of health.
Let's focus a bit more on the often overlooked (and proven) benefits of what you eat and drink and how you eat and drink it.
What you eat and drink
The “calories in, calories out” philosophy (i.e. how much you eat) is being drowned out with research on other factors that may be just as important. Don't get me wrong limiting calories, carbs or fat can certainly help you lose weight but that's simply not the only factor for long-term weight loss and maximum energy for everyone.
When the intense focus on how much we ate didn't work in the long-run it wasn’t really a surprise. We kinda knew that already, didn't we?
You can certainly still continue to count your calories, carbs, and fat but don't forget to also pay attention to what you eat.
Ideally, you need a varied diet full of minimally-processed foods (i.e. fewer “packaged” “ready-to-eat” foods). This simple concept is paramount for weight loss, energy, and overall health and wellness.
Every day this is what you should aim for:
How you eat and drink
Also pay attention to how you eat and drink.
Studies are definitely showing that this has more of an impact than we previously thought.
Are you rushed, not properly chewing your food, and possibly suffering from gastrointestinal issues? Do you drink your food?
When it comes to how you eat let's first look at “mindful eating”.
Mindful eating means to take smaller bites, eat slowly, chew thoroughly, and savour every bite. Notice and appreciate the smell, taste and texture. Breathe.
This gives your digestive system the hint to prepare for digestion and to secrete necessary enzymes.
This can also help with weight loss because eating slower often means eating less. Did you know that it takes about 20 minutes for your brain to know that your stomach is full?
We also know that more thoroughly chewed food is easier to digest and it makes it easier to absorb all of those essential nutrients.
And don't forget about drinking your food.
Yes, smoothies can be healthy and a fabulously easy and tasty way to get in some fruits and veggies (hello leafy greens!) but drinking too much food can contribute to a weight problem and feelings of sluggishness.
Don't get me wrong a green smoothie can make an amazingly nutrient-dense meal and is way better than stopping for convenient junk food – just consider a large smoothie to be a full meal not a snack. And don't gulp it down too fast.
If your smoothies don't fill you up like a full meal does try adding in a spoon of fiber like ground flax or chia seeds.
Consider not only how much you eat but also what and how you eat it.
Recipe (Smoothie meal): Chia Peach Green Smoothie
1 tablespoon chia seeds
1 chopped peach
1 cup unsweetened almond milk
Add ingredients to blender in order listed (you want your greens on the bottom by the blade so they blend better and have the chia on the bottom to absorb some liquid before you blend).
Wait a couple of minutes for the chia seeds to start soaking up the almond milk.
Blend, Serve and Enjoy!
Tip: Smoothies are the ultimate recipe for substitutions. Try swapping different greens, fruit or seeds to match your preference.
Bonus: Chia seeds not only have fiber and essential omega-3 fatty acids but they contain all of the essential amino acids from protein.
This word “metabolism” is thrown around a lot these days.
You know that if yours is too slow you might gain weight. But what exactly does this all mean?
Well technically “metabolism” is the word to describe all of the biochemical reactions in your body. It's how you take in nutrients and oxygen and use them to fuel everything you do.
Your body has an incredible ability to grow, heal, and generally stay alive. And without this amazing biochemistry you would not be possible.
Metabolism includes how the cells in your body:
So when you put all of these processes together into your metabolism you can imagine that these processes can work too quickly, too slowly, or just right.
Which brings us to the “metabolic rate”.
This is how fast your metabolism works and is measured in calories (yup, those calories!).
The calories you eat can go to one of three places:
As you can imagine the more calories you burn as work or creating heat the easier it is to lose weight and keep it off because there will be fewer “leftover” calories to store for later.
There are a couple of different ways to measure metabolic rate. One is the “resting metabolic rate” (RMR) which is how much energy your body uses when you're not being physically active.
The other is the “total daily energy expenditure” (TDEE) which measures both the resting metabolic rate as well as the energy used for “work” (e.g. exercise) throughout a 24-hour period.
What affects your metabolic rate?
In a nutshell: a lot!
The first thing you may think of is your thyroid. This gland at the front of your throat releases hormones to tell your body to “speed up” your metabolism. Of course, the more thyroid hormone there is the faster things will work and the more calories you'll burn.
But that's not the only thing that affects your metabolic rate.
How big you are counts too!
Larger people have higher metabolic rates; but your body composition is crucial!
As you can imagine muscles that actively move and do work need more energy than fat does. So the more lean muscle mass you have the more energy your body will burn and the higher your metabolic rate will be. Even when you're not working out.
This is exactly why weight training is often recommended as a part of a weight loss program. Because you want muscles to be burning those calories for you.
The thing is, when people lose weight their metabolic rate often slows down which you don't want to happen. So you definitely want to offset that with more muscle mass.
Aerobic exercise also temporarily increases your metabolic rate. Your muscles are burning fuel to move so they're doing “work”.
The type of food you eat also affects your metabolic rate!
Your body actually burns calories to absorb, digest, and metabolize your food. This is called the “thermic effect of food” (TEF).
You can use it to your advantage when you understand how your body metabolizes foods differently.
Fats, for example increase your TEF by 0-3%; carbs increase it by 5-10%, and protein increases it by 15-30%. By trading some of your fat or carbs for lean protein you can slightly increase your metabolic rate.
Another bonus of protein is that your muscles need it to grow. By working them out and feeding them what they need they will help you to lose weight and keep it off.
And don't forget the mind-body connection. There is plenty of research that shows the influence that things like stress and sleep have on the metabolic rate.
This is just the tip of the iceberg when it comes to metabolism and how so many different things can work to increase (or decrease) your metabolic rate.
Recipe (Lean Protein): Lemon Herb Roasted Chicken Breasts
2 lemons, sliced
1 tablespoon rosemary
1 tablespoon thyme
2 cloves garlic, thinly sliced
4 chicken breasts (boneless, skinless)
dash salt & pepper
1 tablespoon extra virgin olive old
Preheat oven to 425F. Layer ½ of the lemon slices on the bottom of a baking dish. Sprinkle with ½ of the herbs and ½ of the sliced garlic.
Place the chicken breasts on top and sprinkle salt & pepper. Place remaining lemon, herbs and garlic on top of the chicken. Drizzle with olive oil. Cover with a lid or foil.
Bake for 45 minutes until chicken is cooked through. If you want the chicken to be a bit more “roasty” then remove the lid/foil and broil for another few minutes (watching carefully not to burn it).
Serve & enjoy!
Tip: You can add a leftover sliced chicken breast to your salad for lunch the next day!
