Apps that pay you to log your meals, and why consistency wins

Why logging often beats logging perfectly

Writing down what you eat is one of the most common tools in healthy-eating and weight-loss programs. The CDC suggests writing down, or using an app to track, everything you eat and drink for a few days. It helps you see what you actually eat and think about small changes.

Research points the same way. A review of 22 studies on self-monitoring, most of them about food diaries, consistently found a link between self-monitoring and weight loss. The authors also noted that the evidence was weak because of limits in how the studies were done.

What seems to matter most is how often you log, not how long you spend. In a 24-week online weight-loss program with 142 adults, people who lost at least 5% of their weight opened their food journal more often each day than those who lost less (2.4 times versus 1.6). The time people spent logging wasn't linked to how much they lost, and it dropped from about 23 minutes a day in the first month to about 15 minutes by the sixth.

So a quick, honest log every day is more useful than a perfect log once a week. That's why an app that rewards consistent logging can make sense.

How meal rewards work in AHEALTH

Log what you ate, earn points. Meals are one of the healthy habits AHEALTH rewards in the U.S. When you log what you ate in the app, you earn points. Point amounts differ by habit and can change over time.

Redeem points for gift cards. In the U.S., you spend your points in the app's Gift Shop on email gift cards from more than 25 brands, including Amazon, Walmart, Target and Starbucks. Gift cards start at $5 for Amazon and Dunkin', and most other brands start at $10. They usually arrive by email within 1 to 3 days. See how AHEALTH rewards work.

Meals are one habit of many. The same points also come from walking, logging your sleep and water, medication reminders and quick daily habits such as breathing exercises and stair climbing. If you want one app for several small habits, see how AHEALTH rewards micro-habits.

AHEALTH is a healthy-habits app, not a diet program, and it doesn't give medical nutrition advice.

How to log your meals quickly and honestly

A food log only helps if you keep it up. These habits make that easier.

1. Log right after you eat. Waiting until evening makes it easy to forget a snack or a drink. Logging at the table takes a few seconds.
2. Include drinks and snacks. The CDC suggests including everything you consume, not just main meals. Drinks and small snacks are the easiest things to forget.
3. Log the meals you're not proud of. An honest log is more useful than a flattering one. Nobody grades it but you.
4. Notice how you felt. The CDC also suggests paying attention to how you feel when you eat and drink. Were you hungry, tired or stressed? Patterns are easier to spot over a week.
5. If you miss a meal, log the next one. The CDC notes that occasional setbacks are expected. What matters is getting back on track quickly.

Turn your food log into small changes

After a week or two of logging, look back at what you wrote. You don't need to change everything at once. The CDC suggests focusing on two or three specific, realistic goals at a time, such as drinking water instead of sugary drinks or having a vegetable with supper. When you consistently meet a goal, add a new one.

• Swap one drink. If your log shows soda or sweet tea every afternoon, try water instead. AHEALTH also rewards logging each glass of water.
• Add one vegetable. Pick one meal a day where a vegetable is easy to add.
• Plan ahead. If your log shows takeout on busy nights, planning a few meals ahead of time can help.
• Walk after a meal. A 10-minute walk after each meal adds up to 30 minutes a day, and your phone counts the steps.

If you have diabetes, kidney disease, a history of disordered eating or another health condition, talk with your doctor or a registered dietitian before you start tracking food or changing your diet.

What to look for in an app that rewards meal logging

• It rewards showing up. Look for points for logging itself. That matches what research suggests matters most: logging often.
• Logging is quick. If one entry takes minutes, you'll stop. A few seconds per meal is easier to keep up.
• Reward prices are clear. You should see what a reward costs before you start. In AHEALTH's Gift Shop, every reward shows its price in points.
• You know how it's paid for. AHEALTH is free to download and is supported by in-app advertising and partner offers, which fund the rewards users earn.
• It doesn't promise weight loss. Be careful with any app that guarantees results. A food log is a tool for noticing your habits, not a medical treatment.
