How is Burn different from basic streak counter apps?

Most sugar apps only count streaks (Did you eat sugar? Yes/No). Burn is an experiment engine that measures what actually happens to your body: energy reliability, craving peaks (typically days 2-5), sleep quality, and digestion.

Do I have to quit fruit or natural sugars?

No. The Burn No Sugar Challenge focuses on eliminating added sugars (syrups, refined cane sugar, soda, candy, desserts). Whole fruit containing natural fiber is completely fine.

How long should my first sugar experiment be?

We recommend starting with 14 days. 7 days is often dominated by withdrawal adjustments, while 14 days provides enough time to observe genuine shifts in energy and cravings.

What Happens When You Quit Added Sugar for 14 Days?

Not a generic streak counter. A real personal experiment.

Most challenge apps only ask: "Did you eat sugar today?"
Burn tracks what actually changes: Energy stability, cravings, sleep, mood, and digestion.

14-Day Experiment: The Sweet Spot

Two full weeks give your taste receptors time to reset and allow your body to pass the initial withdrawal peak (Days 2–4). By Day 10, natural foods taste sweeter and afternoon sugar crashes decline.

How the 14-Day Experiment Works

Days 1–3: The Adjustment Phase

You cut added sugars (sodas, pastries, hidden dessert sauces). Craving signals will be highest here. Burn logs your difficulty without judgment.

Days 4–9: Taste Buds & Energy Reset

Blood sugar swings subside. Afternoon energy crashes typically decrease and cravings begin to soften.

Days 10–14: Clear Results

Compare your day 14 baseline to your start. Burn compiles your shifts so you can decide your permanent sugar strategy.

Frequently Asked Questions

What counts as "added sugar"?

Added sugars include granulated sugar, high-fructose corn syrup, honey/agave added to drinks, sweetened baked goods, sweetened coffee syrups, and candy. Whole fruits and unflavored dairy contain natural sugars accompanied by fiber/protein and are allowed.

What if I accidentally eat sugar on Day 5?

Don't panic and don't abandon the experiment. In Burn, you simply log the day honestly. Your final report accounts for adherence (e.g. 13/14 days) and still provides meaningful before-and-after insights.

Is the app free to start?

Yes! Burn allows you to launch your first experiment 100% free on Android and iOS.
