How to Track Your Food Without Losing Your Mind

The short version

• People who keep track of what they eat tend to lose more weight, and the method matters less than doing it.
• Nearly everyone underestimates. Cooking oil, drinks, sauces and weekends are the usual gaps.
• Photos and hand-sized portions work when counting calories feels like too much.
• If tracking makes you anxious or obsessive, stop. It isn't for everyone.

Why track at all?

A review of 22 studies found a consistent link between self-monitoring and more weight loss. It works partly by giving you information and partly because writing down the second brownie makes you think about it first.

You don't need to do it forever. Many people track intensely for a few weeks to learn their habits and portions, then go back to it when things drift.

Pick your level

Hand portions

A rough portion guide that's always with you:

• Palm: a serving of protein (about 3 to 4 oz cooked)
• Fist: a serving of vegetables, or a cup of cooked grains
• Cupped hand: a serving of carbs like rice, pasta or fruit
• Thumb: a serving of fats like oil, butter or nut butter

Photo log

Take a picture of everything before you eat. Flip through at the end of the week. You'll see patterns quickly, and it takes seconds.

Where the calories hide

If your log says 1,600 calories and the scale says otherwise, look here first:

• Cooking oil and butter. One tablespoon of oil is about 120 calories, and most people pour more than that.
• Drinks. Coffee drinks, juice, alcohol and smoothies.
• Nibbles. Bites while cooking, kids' leftovers, the office candy dish.
• Sauces and dressings. Ranch, mayo and creamy sauces can match the calories of the meal itself.
• Nuts and peanut butter. Healthy, but dense. A generous spoon of peanut butter can be twice a labeled serving.
• Restaurant meals. Often more than you'd guess, and app entries can be unreliable.
• Weekends. Tracking Monday to Friday and skipping Saturday can erase the week's deficit.

Keep it from taking over

• Aim for "mostly," not "exactly." A rough log you keep beats a perfect one you quit.
• Log it even when it's bad. Those are the days that teach you the most.
• Repeat meals. Eating the same breakfast and lunch on most days makes it almost effortless.
• Don't "earn" food with exercise. Calorie burn estimates from apps and watches can run high.
