If you’re looking to get optimal results from your diet, then food logging is hands-down the way to go.
While there are a plethora of diets that can be effective in helping you reach your fitness goals, no rules-based diet (such as Paleo, Whole30, Atkins, etc.) can come close to matching the exactness and precision of flexible dieting with a food log.
But there’s one big problem with the food logging approach…
I’ve worked with hundreds of clients and there’s a pattern that’s very easy to spot:
The people who keep an accurate food log nearly always get consistent and expected results, while those who struggle with their food logs tend to get off track much more frequently.
Now, for some of these people who don’t do well with food logging, the issue lies more with personality compatibility. In other words, the idea of logging their food drives certain types of people crazy because they see it as far too fussy and would prefer not to do any calorie counting at all.
For these types, we usually change strategies and switch to either meal plans or a rules-based diet.
But the majority of those who struggle with food logging don’t struggle for this reason. Instead, they have major issues with getting an accurate sense of their calorie and macronutrient intake because they’re just not very good at logging.
Let’s take a look at an example…

How Bob Logs A Cheeseburger
Bob is just a regular guy who wants to lose some weight and put on muscle. He’s following a flexible dieting plan put together by his online personal trainer. Bob goes to the diner and orders a big, juicy cheeseburger. The cheeseburger looks like this:
He opens up MyFitnessPal, the most popular food logging app, on his iPhone to log the burger. Bob searches for “cheeseburger” and here’s the first thing that comes up:
Not only is this the very first item that shows up when Bob searches for “cheeseburger”, it also has the trusty MyFitnessPal “verified” label on it, so Bob is confident in his choice and adds it to his food journal.
The big problem here?
The cheeseburger that Bob logged as 300 calories is actually more likely to be in the realm of 800-1200 calories.
Which means that Bob actually ate 500-900 additional calories that are unaccounted for in his food journal. And this is just one inaccurate entry!
Now let’s say Bob’s calorie target is around 2000 calories per day. Due to inaccurate food logging, even though Bob thinks he’s eating 2000 calories, he’s actually regularly consuming nearly 3000 calories per day. Instead of losing weight, he’ll actually be gaining weight because he’s eating more than he should be.
I still stand by my assertion that food logging is the optimal way to transform your body whether you want to cut, bulk, or recomp. But for food logging to be effective, you have to make an effort to be as accurate as possible with your logs.
And we’re going to help you do just that.
We’ve been logging our food nearly every single day for over 5 years now, and I like to think we’ve gotten pretty good at it.
I’m going to share with you everything we’ve learned over the years to not only keep a food log that’s as accurate as possible, but also to do so without spending too much time or energy on it.
Choosing The Right Food Logging App
MyFitnessPal is, by far, the most popular food logging app, with over 80 million users and growing when it was purchased by Under Armour back in 2015. But just because it’s the most popular, does that mean you should use it?
In my opinion, the answer is a definitive NO.
MyFitnessPal has the biggest mess of a food database of all the food logging apps I’ve tried – and I’ve tried many.
No matter what kind of food you’re searching for, MyFitnessPal forces you to wade through an endless sea of sloppy food entries entered by other users with wildly inaccurate nutrition information.
And even though MFP has a “verified” label, the verification process is still based on user input, and a lot of these verified entries are inaccurate themselves, making the entire verification process pretty much useless.
Let’s see what you get when you run a basic search for “chicken” on MyFitnessPal:
The top 3 menu items are KFC Menu, an unverified “Chicken…” entry, and chicken spread. Ouch. Such a basic search and such poor results. Highly doubtful that someone who just wants to log chicken in their food journal is looking for KFC or chicken spread (and let’s not even talk about that “Chicken…” entry).
So what’s the alternative to MyFitnessPal? Here at Caliber Fitness, we highly recommend FatSecret. We’ve been using FatSecret ourselves for over 5 years to log our food, and we also recommend it to all of our clients.
Let’s compare MFP’s search results for “chicken” to the results you get when you do the same search on FatSecret:
See the difference? Much cleaner search results, and much more useful. The top 3 results are chicken breast, skinless chicken breast, and grilled chicken. Chances are that one of these items is what you’re looking for.
Furthermore, all of these entries can be entered either by serving size, weight in ounces and grams, or volume. This is extremely important because the most accurate method of entering most foods is based on weight (more on this in the next section).
Even better, every single food entry in FatSecret is already verified – and not by a consensus of users, but by a manual review of FatSecret staff. This leads to a much more organized food database that makes it a breeze to find what you’re looking for.
Another benefit of using FatSecret?
It has these types of verified listings for a whole bunch of foods that are not quite as common as your basic search for “chicken”. FatSecret’s database includes accurate, verified entries for an incredibly wide variety of foods from a range of cuisines.
I cannot stress to you enough the importance of working with a clean, well-organized food database such as the one you get with FatSecret. It makes logging your food every day so much easier because you don’t have to spend time navigating a complete mess trying to figure out what you ate for lunch.
I should note here than in no way am I being paid by FatSecret to promote them, I just honestly think it’s the best app for keeping an accurate food journal.
If you still want to use MyFitnessPal, that’s completely fine, but it’s going to take you a lot more work to individually verify everything you eat. This is OK if you eat the same exact menu everyday, but when one of the biggest benefits of flexible dieting is being able to incorporate all sorts of different foods you enjoy into your diet, having a good database is tremendously beneficial.
Food Logging Basics
Now it’s time to get into the actual process of food logging itself. There are 3 primary ways to log the food you eat: fixed serving size, weight, and volume. Let’s take a look at these methods and see when it is appropriate to use each one.
Fixed Serving Size
This is what you would use when eating something that’s prepackaged and has a clear-cut nutrition label. For example, two slices of Pepperidge Farm wheat bread, a packet of instant oatmeal, or a pack of Skittles. This is also the best option for logging food at restaurants and fast food places that have nutrition information based on the dish.
Note that you should use this method ONLY for foods where the serving size is always exactly the same every time you eat it.
A pack of Skittles is always going to match the nutrition information on the label. On the other hand, if you’re eating fresh bagels from a bakery, the size can vary significantly and you want to make sure to use an alternative measurement.
Here’s an example of choosing a fixed serving size in FatSecret:
If you’re eating a food without a fixed serving size, then the next best option is to break out the food scale and weigh it in ounces or grams. Weighing your food on a scale is typically the most accurate way to log most foods, even for foods that you may think it’s better to measure in terms of volume like cereal and peanut butter.
Weighing your food requires you to have access to a food scale which can be cheaply purchased at Amazon. I use the Ozeri Pronto food scale (pictured above) which is less than $12 on Amazon.
Here’s an example of how to log strawberries based on weight:
You should also know that almost every nutrition label includes the weight equivalent of its serving size. So if you’re eating potato chips and the serving size is 17 chips, you’ll see from the label that 17 chips will equal approximately 28 grams:
Measuring your food in terms of volume means measuring your food in tablespoons, cups, fluid ounces, etc. This is the best option when measuring liquids and sauces, and is also useful for eyeballing food when you’re not at home and don’t have access to a food scale.
Otherwise, the volume method is generally the least preferred method of all 3. That’s because it’s far too easy to scoop out a giant heap of Nutella or peanut butter and claim that it’s only a tablespoon. Unless it’s a liquid or a sauce, stick to weighing out your food if you have access to a food scale.
Here’s an example of logging 1 cup of milk based on volume:
Now that we’ve reviewed the three primary methods used for food logging, let’s take a look at the best approach in various situations. You’re not exactly going to pull out a food scale in the middle of a work lunch or at a restaurant, so your strategy will have to shift depending on the circumstance.
Food Logging At Home
Being at home is clearly the most conducive environment for accurate food logging. You can weigh out each of your meals in a judgment-free zone without the fear of being embarrassed about your diet.
When you’re home, there are generally only two scenarios: you or someone else is cooking or preparing a meal for you, or you’re eating take-out / delivery food from a restaurant.
If you’re the one doing the cooking, then logging your food is as easy as logging each of the ingredients in the meal and dividing them by total servings.
For example, here are the recipe ingredients for Buffalo chicken with sweet potato fries:
- 1 tablespoon of vegetable oil
- 1 tablespoon of extra virgin olive oil
- 1 pound of boneless skinless chicken breast
- 2 large sweet potatoes (weighing 700 grams in total)
This recipe makes two servings, so I divide each ingredient by 2 and log the meal like this:
If someone else is doing the cooking for you, you can ask him or her to give you the ingredient list so you can calculate it yourself.
And if this is a meal you eat frequently, be sure to save this meal in MyFitnessPal, FatSecret, or the food logging app of your choice so you can re-enter it easily in the future. While the first time you enter a recipe may take a few minutes to enter each ingredient, saving the meal makes entering it in the future a breeze.
As a general rule, the more you can incorporate home-cooked foods into your diet, the more accurate your food log will be, and therefore your results will be better. It’s much easier to incorporate delicious, high-protein meals into a balanced diet when you’re controlling exactly what’s going into your meals.
Take-Out / Delivery
If you’re eating restaurant food at home, then the food scale is going to be your best friend. No matter what you’re eating, you basically want to weigh out the components of each meal and record them individually. This will help you get the most accurate nutrition for whatever you’re eating.
Keep in mind that it’s never going to be as accurate as logging cooked food because you can’t be sure of all the individual ingredients, how much oil is used, etc., but weighing out your food is by far the best option in this scenario.
Here’s an example of a dinner I regularly order from a local Italian restaurant:
And this is how I log it:
All I did was weigh out the pasta, chicken, and bread, and log each of those foods in my journal. Because this is a frequently eaten meal for me, I save it in FatSecret so I can add it to my logs with a simple click.
The biggest challenge when logging food from restaurants occurs when you order cuisines that you may not know how to find in the food database, such as Chinese, Indian, Thai, etc. For more information on how to log foods like these, see the later section in this guide called “Food Logging Examples”.
Food Logging At Work
Figuring out how to log your food at work is a big challenge for a lot of our clients, but certainly not one that’s insurmountable.
For most people, the meal you have at work is going to be lunch. If you prepare your own lunch at home, then this part is easy; you simply weigh out the ingredients or the individual components of the dish when you’re home and use that information in your logs.
But what if you have a favorite spot where you like to pick up your lunch each day? Or you rotate through 4-5 local restaurants where you enjoy going out to lunch with your coworkers?
In these cases, if there’s a lunch you frequently eat but don’t have access to a scale to weigh out the individual portions of food, you have two options:
Use rough estimations and enter your food based on the guidelines in the next section, “Food Logging At Restaurants”.
The “Double Lunch” Method
Figure out what’s in your most frequently eaten lunches, weigh them out ONCE and save to your Favorite Meals in the app, and then use the saved meal each time you eat that lunch.
To figure out what’s in these lunches, you can either bring a food scale to work and try to weight out each component in your office kitchen without anybody noticing, OR you can do what I’ve advised numerous clients to do…
If you’re going out for one of your favorite lunches, order TWO servings of whatever you normally get. Put one of these lunches in the fridge for you to take home. Weigh out each component of the dish when you get home, log it in your food journal, and then bring that second lunch to work the next day. This way you can figure out the nutrition info for each of your favorite lunches without bringing a food scale to work, and without wasting food.
Food Logging At Restaurants
When you’re eating out at a restaurant, or eating any meal in a situation where you don’t have access to nutrition information or a food scale, then you’re going to need to work on your serving size estimation skills.
Even though eyeballing serving sizes is clearly going to be the least accurate way to enter meals into your food log, it’s extremely helpful for those of us who tend to eat out a lot and want to get as close an estimate as possible for whatever we’re eating.
If you’re eating protein-centric meals where protein is the main ingredient, then the first thing you need to do is estimate the weight of the protein on the plate, whether it is chicken, beef, or fish. A good rule of thumb for this is:
3 ounces of meat, fish, or poultry = 1 deck of cards
I’ve been using this basic guideline for years and it generally holds up. It will never be perfect, of course, but we’re not looking for perfect in this case – just as close as you can get to a reasonable estimate of the food you eat.
Sometimes restaurants will list the weight of the piece of meat you’re ordering, like a 1/2 pound burger, 12 ounce ribeye steak, etc. In this case, just enter that amount into your food logs, being sure to log the raw version of whatever meat you’re selecting. Whenever a restaurant lists the weight of a burger, steak, lobster, etc, it always uses the pre-cooked weight.
You can get better at estimating meat weights by practicing at home when you have access to a food scale. Whenever you’re weighing meat on your food scale at home, take a second to guess what weight it is using the deck of cards rule listed above. You’ll find that this is a skill that improves with practice.
The next step is to estimate your sides. While it’s easy to estimate the weight of protein using the deck of cards rule, there’s no such rule for weighing other foods because there’s too much variation.
That’s why the key here is to estimate your sides in terms of volume, and more specifically in terms of cups or tablespoons, using the following two guidelines:
1 cup = 1 baseball
2 tablespoons = 1 golf ball
So if you’re having a side of rice, mashed potatoes, pasta, etc., try to estimate how many cups it is by estimating how many “baseballs” it looks like.
Let’s put it all together by showing you how to log a typical dish you might order at a restaurant. Say you go to an Italian restaurant and order the chicken marsala:
Here’s how I would log this meal in FatSecret:
Even though there’s likely more than 6 ounces of chicken on this plate (2 decks of cards), I would choose to only eat “2 decks of cards” worth of chicken to limit the number of calories in the meal. If I ate the full thing, I’d likely log closer to 9 ounces of chicken (3 decks of cards).
As for the sides, it looks like there is a “baseball” of roasted potatoes and a “baseball” of string beans, so that’s why I logged 1 cup of each.
Also, notice that I chose the vegetable entries that had “Fat Added in Cooking” in the description. That’s because unless you’re ordering steamed veggies, restaurants pretty much always cook with fat added. All this means is that the cook used some sort of oil and/or butter when cooking the vegetables.
(This is also another benefit of FatSecret, because it has these “Fat Added in Cooking” entries for nearly all vegetables.)
Food Logging Examples
In this section I’m going to show you how I would personally log a bunch of different food items. I’ve found that the best way to teach accurate food logging to clients is through lots of examples.
Remember at the beginning of this post when I showed you how Bob logs a cheeseburger? Well let’s take a look at that example again and now I’ll show you how I would personally log that same cheeseburger.
Here’s the image of the burger once again:
And here’s how I would log it:
The basic strategy here is just breaking down the burger into it’s components and logging each ingredient separately. There were about “2 decks of cards” worth of cooked ground beef, 2 slices of cheese, and a large burger bun. As you can see, my original estimate was pretty accurate as this burger is around 800-900 calories.
Pizza is an extremely calorie-dense food if you’re logging it by the slice, I can guarantee that you’re underestimating just how many calories you’re consuming.
Note that this slice of pizza is 175 grams and 483 calories. If you were to log this via the fixed serving size method – 1 slice of pizza – it says that the slice is only 237 calories.
This is why the fixed serving size method isn’t appropriate for many foods, and why it’s so important to weigh out your food whenever you can.
Peanut Butter and Jelly Sandwich
I’m including a peanut butter and jelly sandwich in this list because I cannot tell you how many times I’ve seen clients make PB&Js for themselves, slathering the bread with heaps of peanut butter and jelly, and then log it in FatSecret as only 300 calories when they’re eating that many calories in the peanut butter alone.
Peanut butter is one of those foods that is MUCH better to weigh out than use tablespoon measurements for. Prepare to be disappointed, because two tablespoons of peanut butter at 180 calories is probably a lot less peanut butter than you thought.
Chinese Food – Spicy Diced Chicken, Beef With Broccoli, and Pork Fried Dumplings
Logging non-American cuisines is always a little trickier because there aren’t many “official” entries for these types of foods in either MyFitnessPal or FatSecret (although you will definitely have better luck with the FatSecret database).
The key here is to find something that’s close enough to the dish you’re eating and log it in terms of weight.
One of my most frequently ordered delivery meals is spicy diced chicken, beef with broccoli, and steamed pork dumplings from a local Chinese restaurant.
For the spicy diced chicken, I searched FatSecret for “spicy diced chicken” and got this:
Of the top entries, Szechuan Chicken is close enough, so I choose that one and enter it in terms of grams.
Now let’s search for “beef with broccoli”. This returns several potential options:
Several options could potentially work here, including Pagoda Express, Panda Express, and P.F Chang’s. The first thing I do is rule out any options that don’t allow you to enter the food by weight. That leaves Pagoda Express and Panda Express, which allow you to enter the food in either grams or ounces. Both seem to have similar nutrition, so I choose the Panda Express entry.
Finally, I move on to the dumplings. This is one of those fortunate situations where FatSecret has exactly what I’m searching for:
(I’m choosing the very first entry for “Pork Fried Dumplings”. Ignore the 1 dumpling = 338 calories part because when you weigh them, each dumpling is about 30 grams, so 3 dumplings would be 90 grams, which as you’ll see is still less than 338 calories.)
Putting it all together, and adding white rice to the meal, here’s how the dinner looks in terms of nutrition:
Once you choose the food entry that seems most compatible with what you like to order, you can use those same entries every time you eat that food in the future.
So although it may take me a few minutes to find the most appropriate foods, whenever I order this meal in the future it will take literally seconds to log.
Desserts are often super dense with calories, which makes it extremely important to, yup you guessed it, WEIGH them. I’ve seen people take practically 1/4 of an entire cake and try to get away with logging it as just a slice.
Cakes, cookies, brownies, ice cream, pie…
If you are in a situation where you can weigh them, do it. This will also give you valuable insight into smart portion sizes. You learn that you can easily manage to fit a slice of cake or some cookies into your diet as long as you limit the amount.
Don’t Aim For Perfection. Aim For Consistency.
As a final note, I want to stress the point that you do NOT have to perfect with your food log, and obsessing about whether or not you ate 5 or 6 ounces of chicken is totally unnecessary. Accept the fact that your food log is only ever going to be an estimation of what you eat.
Rather, focus on consistency. As long as you follow the same general methods outlined in this guide, and continue to choose the same food entries in the database for whatever you eat regularly, then you will see success with the food logging approach.
Frequently Asked Questions
Do I log chicken (or any meat) before or after cooking it?
Anytime you’re cooking, you always want to use the weight of the raw chicken (or any meat) BEFORE you cook it, and then make sure to select the appropriate entry for raw meat from the food database.
Most raw chicken that you purchase from a grocery store will come in a package with the weight and nutrition information right on it, like so:
This label shows that 4 ounces of raw chicken breast is 120 calories with 26 grams of protein. The easiest way to log this chicken is to find this brand or an equivalent item in the food database and use that. Note that pretty much all raw chicken breast is 120 calories per 4 ounces, so it doesn’t really matter which brand you pick.
What does “yield after cooking” mean?
When you’re looking through the food database, you may come across the phrase “yield after cooking”. Here’s an example of what this looks like in FatSecret:
You can think of “yield after cooking” as “what this comes to after cooking”. So in this case, for chicken breast that’s boneless, raw, and without skin, you would enter the RAW weight of the chicken you’d be eating, and the resulting nutrition information shows you what that amount of raw chicken would be after being cooked.
How do I count vegetable or olive oil that I use when cooking?
For cooking oils, you want to measure out how many teaspoons or tablespoons you’re using in the cooking process and then enter that amount into your food log. For example, if I’m sautéing chicken cutlets using a tablespoon of olive oil, and I’ll be eating half the dish, then I would log 1/2 tablespoon of olive oil in my journal.
