How many calories do you actually need?

It seems like a simple question but if you’ve ever searched for this on Google, you’ve probably been hit with a wide range of recommendations.

We’ve put together a calorie calculator to help you cut through all the noise.

But here’s the truth: while knowing our calorie needs is helpful, obsessing over exact numbers is often a recipe for frustration.

The goal of this post is to help you find your numbers and a better plan for success.

The Problem With Calorie Counting

Before we dive in, let’s address the elephant in the room. Calorie estimates are just that: estimates.

There are currently six different methods of estimation allowed by the FDA. The rules and regulations around labeling food is rather lengthy and if you’re stuggling to fall asleep, trying to read through these will probably help.

The bottom line is that most calorie counts have an acceptable deviation of around 20%. Meaning a 150 calorie snack you’re trying to log with finite precision could actually be anywhere from 120 to 180 calories.

Then there’s the issue of absorption. We each absorb a different amount of calories from the foods we consume based on our gut microbiome, how the food was prepared, and a dozen other factors.

This isn’t to say that calories don’t matter…they absolutely do. But it does mean that weighing every morsel of food and logging it to the exact gram is probably overkill for most people.

Your Baseline Calorie Needs

According to the 2020-2025 Dietary Guidelines for Americans, daily calorie requirements vary based on age, sex, and activity level:

Males 19-60: 2,200 to 3,000 calories daily

Females 19-60: 1,600 to 2,200 calories daily

That’s a rather wide range. The lower end applies to sedentary individuals while the higher end is for those who are very active.

Most busy professionals fall somewhere in the middle.

For weight loss, creating a moderate deficit of 500 calories per day is the standard approach. This typically results in losing one pound per week (assuming a 3,500 calorie deficit over the course of 7 days).

But here’s where things get interesting: you don’t need to meticulously count calories to create that deficit.

The Only Portion Guide You Need

Americans are notoriously bad at estimating portion sizes. Our super-sized culture has completely warped our concept of what a normal serving size should look like.

The good news? You have a perfectly calibrated portion guide with you at all times: your hand.

Here’s how it works:

Your palm determines your protein portions. One palm-sized portion of meat, fish, or poultry for women and two palm-sized portions for men.

Your fist measures vegetables. One fist equals about one cup of veggies. The recommendation is the same with one fist-sized portion for women and two fist-sized portions for men. The good news is that veggies are nutrient-dense and not calorie-dense so you might be able to fill half your plate with veggies you enjoy.

Your cupped hand measures carbohydrates like rice, pasta, or potatoes. Again the recommendation is one cupped hand for women and two cupped handfuls for men.

Your thumb sizes fats like oils, butters, or cheese. One thumb-sized portion equals about one tablespoon.

The beauty of this system is that your hand scales with your body. Larger people generally have larger hands and need more food. Smaller people have smaller hands. It’s self-adjusting.

Plus your hands are always with you and you’re unlikely to bring a food scale to a restaurant.

Putting It All Together

For most busy professionals, here’s how a solid meal should be composed:

1-2 palms of protein

1-2 fists of vegetables

1-2 cupped handfuls of carbs

1-2 thumbs of fat

Men typically aim for the higher end and women on the lower end. Adjust based on your hunger, activity level and overall goals.

If you’re not seeing the results you want, reduce your carbs and fats by half a serving before making any drastic changes.

Or you could pretend like you’re Deadpool when he had tiny hands.
