3 Reasons Why Counting Calories Isn't as Easy at It Seems



Calorie counting is easily one of the most effective ways to lose weight. Flexible dieting (or “IIFYM”) has become one of the biggest nutrition crazes as of late, with fitness influencers posting the macronutrient breakdown of their meals. They weigh their portions and track their intake. While it has been proven that a caloric deficit will ultimately result in improvements in body composition, the story isn't quite so clear cut. In fact, you may be counting your intake and misinterpreting what all of that information means.


A kilocalorie, more commonly referred to as a “calorie,” is the amount of heat that is required to raise the temperature of 1 kilogram of water one degree Celsius. While we still have a lot yet to learn about the science of nutrition and digestion, there are a few ways in which your caloric estimates may be inaccurate.


Calorie labels aren't always accurate.


Your body breaks down all foods differently, depending on their chemical and nutritional profile. For example, researcher Janet Novotny and her colleagues tested the nutritional content of walnuts. She found that we metabolized about 21% less energy than was predicted by the labels. So, a serving of walnuts might say that it is 180 calories, but we are only possibly absorbing about 145 calories. That is a pretty substantial disparity in caloric intake!
Additionally, Gebauer at all tested different types of almonds (whole unroasted, whole roasted, chopped roasted, and almond butter) in equivalent quantities. Surprisingly, the body absorbed the most calories from the almond butter, followed by the whole chopped roasted almonds. Subjects absorbed the least amount of calories from the whole unroasted almonds. It seems as though the roasting process changes the structure of the almond's cells allowing our bodies to digest more of the nut. It appears that if you're looking for the greatest bang for your buck with nuts, the raw variation is far superior to a nut butter. The exact reason for this phenomenon is unknown to date.


Another study done by Carmody et. al. concluded, "...cooking substantially increases the energy gained from meat, leading to elevations in body mass that are not attributable to differences in food intake or activity levels." This means that we are able to absorb more calories from cooked meat than the equivalent amount of raw meat. Here, the cooking process alters the way it is digested and used for energy, in that our bodies can extract more chemicals from cooked food, as they do not have to work as hard to break them down. That is to say that one would expect to consume more calories from a well-done steak than from an equivalent sized medium-rare steak.


Dr. David Bauer notes that "calories are created equal, but their availability from foods is not equal." So what we do with the calories we consume is highly variable based on the processing (or lack thereof) of those foods.


Dietary fiber can influence weight loss.


The USDA recommends that women get about 25 grams of fiber per day, and men get 38 grams per day, yet some estimates report that many people only get 12-18 grams per day. A few studies have guessed that fiber can influence not only our satiety (leading to a decrease in caloric consumption), but also the size of our waists.


A study done by Du et. al. of fiber intake in European citizens over the course of  about 7 years found an inverse correlation between cereal fiber intake and waist circumference. This means that individuals who increased cereal fiber consumption had smaller waistlines. There was a less significant effect with fiber from fruits and vegetables.


Again, these changes in body composition may be due to the feeling of satiety that comes from an increase in fiber intake, but that is still poorly understood.


So, if you eat 500 grams of oats, the overall satisfaction is going to be very different than eating 500 grams of chocolate crispy cereal. You may find yourself hungry within an hour after eating the gummy worms, whereas the equivalent amount of oatmeal could keep you full for hours on end. If you're in a caloric deficit, it's ideal to choose foods that will give you the most volume for your calories. Our bodies cannot convert certain types of fiber (insoluble fiber) into energy, and thus, it isn't fully digested and you may not absorb as many calories from it.


Your gut bacteria influences the way you digest food.


Now, the science of the gut microbiome is quite new. There aren't a lot of papers (especially not using human subjects) dissecting the gut's influence on weight gain, but the current body of evidence seems to show clear differences in the microbiome of lean versus obese populations.


Research comparing the gut bacteria in lean and obese twins found that obese individuals had a smaller variety of gut bacteria than did their leaner twins. This discussion becomes one of the "chicken or the egg," in that we do not know if the gut bacteria changes due to fat gain, or if those with a specific type of gut bacteria are more prone to weight gain in the first place. Research over the next few years will dissect this topic more.


One case study of a woman who got a fecal matter transplant from her overweight daughter (yes, that's exactly what it sounds like) demonstrated considerable weight gain after the procedure. These procedures are typically done to eliminate harmful gut bacteria, but the side effect of an increase it fat mass was unexpected. Nearly 16 months after the procedure, the woman gained about 34 pounds. After another year-and-a-half, she gained an additional 7 pounds, despite participating in an exercise program and a liquid protein diet prescribed by a medical professional. She was tested for thyroid dysfunction to no avail. While this is a study of n=1, it lead some researchers to speculate that gut health may have a significant impact on body composition.


For now, researchers believe that some individuals with less diverse microbial communities may be more likely to gain body fat, despite their dietary habits. Some individuals can slash their caloric intake down to a mere 1,200 per day and still hold on to ample amounts of body fat.


In short, even if you’re tracking your calories closely, your estimates may be 15-20% off based on the types of foods you eat and the microbes in your gut. If your weight loss is stalling, there might be more to the story than meets the eye and you may have to tinker around with your diet to yield better results. Overall, it’s helpful to consume foods in their raw, unprocessed form (when possible) as it is likely that your body will absorb less energy from them. Additionally, more fibrous foods will keep you fuller for longer periods of time. Ultimately though, your gut bacteria may be to blame for weight gain or weight loss plateaus.

You Are More than Your Numbers



Fitness is a numbers game. Weather it's your bodyweight, inches around your waist, the weight on the bar, your mile time, you're continually looking for those numbers to budge. Active people are constantly weighing, measuring, and comparing. That's how we track our progress.

To a degree, keeping track of numbers is important and necessary, but it can also be counter-productive, when done in excess.



With social media sites like Instagram, Facebook, and Twitter, we are bombarded with status updates, videos, and pictures of people rejoicing over their fitness-related victories. I think this is excellent, but it's also a double edged sword.

We have this tendency, as competitive beings, to compare ourselves to others. We want to be stronger or faster than someone, or we want to look like a cover model in a bikini. It's easy to look at someone who's at a different level than you are and feel as though your accomplishments are, somehow, insignificant.

I, myself have been guilty of this. I've watched more competitive athletes in action and felt frustrated that I was not yet at that level.

I regularly hear my friends or clients say comments to the effect of "I'm not strong. I can't lift that." They look at others in awe, but refuse to entertain the idea that they, too, could reach the same level of athleticism.

The truth is, we get so fixated on a specific number, that we lose sight of the bigger picture. Yes, it's great to quantify your goals, but that's not the only important factor. You want to focus on how you feel, and how you've changed in the long run!

Remember this: the triumphs of others does not take away from your own achievements. Just because someone can run a mile 2:30 minutes faster than you can, does not mean you're slow. If someone's best deadlift is 75 pounds above yours, that does not mean you are weak. If you do not look like Arnold Schwarzenegger, you aren't scrawny.

Our fitness journeys are our own. Celebrate your own successes. A PR is a PR, regardless of whether or not you're going to set a national record. Compare yourself to...yourself, only! The numbers aren't as important in the bigger picture. Consider all of the sacrifices you have made to get to the gym when your schedule was hectic, or when you pushed through a really tough workout. The days you wanted to give up and you chose not to are feats of mental strength. Perseverance is an admirable trait, and every step you make in the right direction is still pushing your forward, in the long run.

Yes, other people are making progress, but so are you! Revel in even the smallest of improvements. Don't tear yourself down just because someone is ahead of you at this time. Instead, use that for motivation to work harder and keep pushing towards accomplishing your goals!

6 Reasons You Aren't Meeting Your Weight-loss Goals




If I had a dime for every time someone asked me how they could lose X number of pounds in X number of time, I could probably make enough money to earn myself a spot in the Shark Tank cast. Everyone seems to have extra weight they want to lose, but yet very few of those people actually want to do something about it. Interesting.

Why aren't you meeting your weight loss goals? Here are couple possibilities as to why:
  1. You're not tracking your intake. There are a million and-a-half different diets and cleanses on the market. The one thing that virtually all have in common is that maintaining a caloric deficit is paramount. To lose weight, you must be consuming less than you are expending. That's it. It's pretty simple! People say you shouldn't eat carbs, you shouldn't eat fat, you should eat carbs after dark, you should carb cycle, you should eliminate sugar/gluten/dairy/etc., you should drink lemonade everyday for a week, blah blah blah. I could continue. None of that is necessary. Just measure how much you're eating and make sure you're moving a lot. You wouldn't load an arbitrary weight on the bar and try to squat it, right? So why would you neglect to keep track of how much food you're consuming? Weigh your food portions, track everything in a food tracker (I use My Fitness Pal), and find out what a good amount of food is for you to start losing weight.
  2. You're inconsistent. You eat "clean" or you track your intake Monday through Friday, and then you go hard and go out drinking and eat whole pies of pizza (guilty as charged) on the weekends. I admire your 5 days of dedication, but you're absolutely destroying all of your hard work over the course of those two days. If you feel inclined to have a day where you don't want to track your calories and just have fun, try to make sure it's not twice-a-week, every week. Make those days fewer and farther between so that you're not sabotaging your progress on the weekends.
  3. You're stressed and/or sleep deprived. Adequate sleep and relaxation are underrated as methods of improving bodily composition. If your body is operating in the sympathetic, "fight or flight" nervous system, as it would in someone who is sleep-deprived and/or overworked, you are constantly in survival mode. Your body is going to instinctually hold on to excess fat (or possibly store more food as fat out of fear) if you are in a constant state of stress! 
  4. You aren't moving enough outside of the gym. Your NEAT is your Non-Exercise Activity Thermogenesis, or the calories you're expending during your other hours of the day. If you work out for 1-2 hours a day and spend the rest of the day sitting at work, your NEAT is going to be pretty low. If you have a physically demanding job or you go on walks/runs during the day, your NEAT is significantly higher. What you do during the rest of your day is important! Now, I understand that not everyone has the option to go on a 3 hour hike during the day, and people do work desk jobs, but try to move whenever you can! Even if it means getting up and walking around your office every half an hour. Maybe you can walk or bike to work. Take the stairs instead of an elevator or escalator. Play with your kids outside when you have time. Just move whenever you have the chance and increase your TDEE (Total Daily Energy Expenditure)!
  5. You aren't eating enough of your micronutrients. This is one huge mistake I made. I was carefully tracking my macronutrients (protein, carbs and fat), but I was forgetting about the micronutrients: my fiber intake, calcium, iron, potassium, Vitamin A, etc. Some of these numbers were much lower than I'd expected. It wasn't until I started monitoring all of this on MFP that I was able to increase my intake. A lot of people aren't hitting these numbers, and the foods they consume are nutritionally devoid. More nutritionally dense foods will keep you full for a longer period of time and they will help improve overall bodily function so you can go crush your workouts.
  6. My Fitness Pal has a large database, and it's easy to use.
  7. You're not working hard enough. It would be fantastic if we could just take a bunch of magic pills and maybe workout once every week for 20 minutes and miraculously have the body of a Victoria's Secret Angel or Brad Pitt in "Fight Club," but unfortunately I'm going to have to pop your bubble: weight loss doesn't work that way. No pill can substitute hours, weeks, months and years of grinding at the gym. No expensive shake is going to allow you to eat a double bacon cheeseburger with a side of fries and still look like an Adonis. Hard work is the only solution to your weight loss woes. Go to the gym as often as your schedule allows and put in the time. Dedication will help you become stronger, faster and leaner (if that is what you desire).
If you're serious about getting in shape, stop talking about tomorrow or next month. Quit making excuses and finding reasons not to do it. The truth is, none of this is easy. I'm not going to sugar-coat it. Some days I'm absolutely exhausted. There are times when people offer me free donuts or candy. Life is a constant struggle filled with temptation. Sometimes I choose to indulge, but often I just tell myself to quit whining and go to the gym anyway. This type of mental strength is the only way to see progress and achieve a lifestyle of health.
