I've seen it a million times. A client comes to me for the purposes of dietary counseling and he or she will tell me, "I hardly eat anything at all."

I ask all of my clients to complete a food diary for me and when I provide them the results, they're shocked at just how much they actually do eat.

Why would these individuals tell me they didn't really eat much at all? Were they trying to fool me?

The answer 95 percent of the time is no, they were actually fooling themselves. The problem is, as our busy lives go on, we tend to eat more than we think we do. We underestimate the exact amount of our daily intake because we fail to take into consideration portion size (usually much larger than what we think), grazing (such as taking a handful of jelly beans from a candy bowl) and fluid calories.

It's only when individuals are asked to write down everything they eat and drink that the true story is told. The importance of keeping a food diary goes way beyond just the food we eat. A recent study following 1,800 men and women over a six-month period showed that those who kept a food diary lost 50 percent more weight than those who did not.

So what's the secret?

Here are few perspectives on why food diaries are important:

  • Accountability: Writing everything down and seeing your daily intake increases your perception of how much you actually eat.
  • Makes you stop before you chomp: The extra helping of ranch dressing in your salad, the candy bar you picked up when you got gas for your car, even the second drink you had at dinner. They could all add up to another 150-650 extra calories throughout the day, yet we tend to forget about these little food extras and instead focus on our main meals. When it comes to food, even a little adds up.
  • Helps to truly portion out your foods: When individuals are asked to keep a food diary, they often must measure all their food for the most accurate assessment. I find that many people measure food based on the bowl or plate the food is eaten on. For example, someone may say they have a "medium bowl of cereal" in the morning when in fact, after measurement, it is determined they actually have a very large serving. Once individuals use more accurate methods of measurement, they have a better understanding of their overall portion distortion.
  • Ties in the connections to stress, emotion, timing and location: I often ask my clients to jot down not only their food choices and amounts but also the time of day, location and emotional level during their meal or snack. This can help people assess how stress may be controlling their food choices. For example, a client of mine realized that she consumed large amounts of chocolate and fried foods after interactions with one of her family members. The family member was clearly a trigger to unhealthy eating but only after seeing the connection on paper did my client realize this. Another client realized he was going six or seven hours in between meals and would gorge because he was so hungry. Many clients are shocked that during the entire day, not one meal was consumed at a table but rather on the couch in front of the TV or in the car. One of my clients realized after she completed her food diary that she ate all her meals standing up and because she was not focusing on her food but rather everything else around her, she ate much more than intended.


Food Logs 101:
You don't need a personal dietitian to start a food log, all you need is the time and commitment to track everything you put in your mouth. Studies show that tracking your food intake for a week or more yields the best results, but even recording your food for one day can make a difference. Be specific and track everything. I tell my clients to carry a pen and paper at all times to record consumption of food. Do not rely on memory because at the end of the day, chances are high that you'll forget something "minor." You'll forget about that sample at a grocery store or your conversation with your co-worker when you grabbed a handful of goodies from her desk -- those calories count.

Remember to accurately assess portion sizes. That means you'll have to measure out all your food choices at least for a few days. You may quickly realize that your portion sizes are much larger than you need and this may force you to assess your goals to consume only appropriate portions of food. For example, a serving of meat should be equivalent to a deck of cards, a bagel should be equivalent to a hockey puck and a serving of peanut butter should only be the size of a ping pong ball.

Make sure to record the time of day and emotions surrounding your food choices. This will help you better assess how far apart your snacks and meals are. The further out your meals are from one another, the greater the fluctuations in your blood sugar will be and the more likely you will overeat at your next meal. Aim for five smaller meals a day rather than the usual three squares. Second, assess any connection between your emotions and your food choices. Knowing your triggers will help you avoid the stress eating pitfalls.

Finally, record where you consumed food and assess how often you are eating in appropriate settings. Food should be consumed in an enjoyable environment free of distractions and disturbances. Several studies show that eating in front of the TV or in the car actually makes us eat much more.

Be Honest
I've seen people get so wrapped up in the food log that they actually start lying to themselves and under-report their food consumption. Remember that honesty is truly the best policy when you are doing a food diary simply for yourself or at the request of a health professional.

Keeping your records may mean further motivation to reach your goals. Keeping a food diary provides a historical perspective on all the amazing changes you've made throughout the weeks, months and years. It provides a tool that can be used to keep your motivation up to make further changes and may also increase your self-esteem as well! Getting back on track with healthy eating is difficult enough. Arming yourself with all the tools you'll need to get on track and stay on track is crucial. Keeping a food diary has been shown to have a dramatic effect on this!

Yes I agree http://www.huffingtonpost.com/irene-rubaumkeller-/how-to-keep-and-use-a-foo_b_151760.html. It is difficult to get people to do it though.

There's an app for that. I downloaded "Lose It" (it's free). It allows you to track your calories and exercise on your phone which is much easier for me than lugging around a journal.

I've read a bit about this and it seems to me that most diary-keepers earnestly try to record everything, but life intrudes, and things are missed.

This was clearly demonstrated in a wonderful BBC documentary called “10 things you need to know about losing weight”. Number 3 is "count your calories" and therein lies the rub... people often under reported them.

You can view this informative video and learn about the 9 other "things" here:

Great article! I am down 62 pounds since March and 45 pounds to go. I don't keep a written record of what I eat but plan on doing that again.

I also measure my portions for things like brown rice, steel cut oats etc. I was finding I had portion distortion.

This can help people shed light on what they actually eat, portion-wise. But most people know what they do, and lie to themselves. Having been 200+ pounds in the late 1990s, I can empathize. But I've only kept a food log to eat healthier, not less. Losing weight was easy. Walk everywhere, drink nothing but water, and carve out 45-60 every day to do something aerobic, like running or another old-fashioned exercise. I've kept the weight off for almost 12 years. It can be done. It just takes being honest with yourself, and sticking to the plan.

"A recent study following 1,800 men and women over a six-month period showed that those who kept a food diary lost 50 percent more weight than those who did not."

This sound impressive, until you consider that, by two years, at least half of both groups will have gained-back all of the weight they lost initially. At five years, only about 5% will have maintained their initial weight-loss, and most (somewhere between one-half and two-thirds) of the remaining 95% will weight more than they did when they started.

At some point, you'd think that people would start to realize that the "weight-loss industry" does nothing more than victimize the obese and create return customers.

Are you lumping the Cleveland Clinic in with Hydroxycut in victimizing the obese? Is Kaiser Permanente part of the "weight-loss industry" you refer to? There are lots of programs out there with incentive to help people get healthy by losing weight and NOT create return customers.

Great post. I recommend this to my clients as well. It has helped many of them achieve their weight loss goals.

So glad to see this article here! I always tell people that the problem with Americans is that we tend to underestimate how many calories we eat and overestimate how many calories we burn. Did you know that unless you're wearing a heart rate monitor, the cardio you do on a machine at the gym is usually not very accurate in telling you how many calories you burned? Portion Distortion is the culprit when it comes to food in the US. Interesting fact is when people buy groceries at places like Costco and WalMart, where the packages of food are bigger also makes us eat larger portions? I wish there was a way to get the food industry on board with portion size!

Ten pounds of fat contain roughly 40,000 calories.

Over ten years, at 2,000 calories a day, a human being will consume 7,300,000 calories.

To maintain weight within ten pounds over ten years by counting calories requires an accuracy of about 0.5%, or 11 calories a day.

Are you seriously proposing that anyone who doesn't live outside a laboratory can estimate their caloric intake within 11 calories every day for ten years?

Be very careful with the food diary - or ANY method designed to help you lose weight (as opposed to becoming more healthy and fit).
Anorexia is a mental illness with a very high fatality rate, and its onset is triggered by dieting.
If you find yourself afraid to put anything in your mouth without writing it down, you may be headed in a very dangerous direction.Keep the focus on health, and you'll be a lot safer.

Seriously, it's time.

I suspect that very few of those who might benefit from the cold slap of reality dealt by a food diary are at risk of anorexia.

You are absolutely wrong about that. Food diaries are used obsessively by most anorexics and bulimics. It "feeds" the illusion of control, and it's a key part of the disease.

I HATED the idea of keeping track of what I ate, but then one day, I decided to do it. I diligently researched the calories in everything I'd eaten earlier that day. I wasn't surprised at the calorie number, but I knew that from that moment on that if I kept doing this, losing weight will be a little easier because I'll know how many calories I've consumed in a day. For simplicity, the number of calories in a meal are usually rounded up (e.g. a meal of 365 calories is rounded up to 400). Apparently it's working (20+ pounds in about two months), and it takes less than 5 minutes out of the entire day.

Food diary is a good option, because it actually works in comparison to all the nonsense that is out there.

Thanks for these great tips, Kristin. I recently lost 85 pounds and being mindful of every morsel I put into my mouth is what keeps me focused on my goal. People I know who don't eat for long periods of time often overdo it once they do eat. I suggest they eat 3 meals and 2-3 snacks a day, so hunger won't be an issue, and making smart choices will be easier to do.

I track everything I eat with an online tool, and I weigh and measure my food. It's amazing how you assume that piece of chicken is about 3 ounces, but when you put it on the scale it is actually 7 ounces.

It's a lifestyle that will be very rewarding, but you do have to prepare and work your program.

Congrats on the willpower!
I started tracking my food last week, and OMFG I got a shock on how much I was consuming. Especially how much calories there is in liquids. One latte, one juice and a cookie extra a day really adds up over the months.

I always thought that keeping a food diary would be too cumbersome and a pain, so I never tried it.
Your up-front approach with tips and suggestions makes this sound so easy and fun that I just started by writing my lunch! uh oh, I'll be better at dinner after my snack.
Thanks, you really inspire me to be stay healthy.

I'm an ACE certified personal trainer with over 17 years of experience in the health and fitness industry and a food diary is one of the most effective tools I know of for helping people to change their eating habits, and to lose weight.

I agree.
