What is a Winter Arc?
A winter arc is the stretch between autumn and the new year that you spend quietly working on yourself, instead of waiting for January's resolutions. The Mango Bites Winter Arc turns it into a 28-day weight loss challenge: every day you eat within your calorie deficit, walk and drink water, and Mangi, your virtual pet, adds a piece to his winter camp.

Every day, three things
Mangi does them with you. Any progress counts: one of the three already brings today's piece.
Eat in your green zone
Your calorie deficit range. Scan a meal and Mangi eats it too.
Walk
Your steps count, and Mangi walks with you.
Drink water
Tap a glass. Mangi drinks with you.
All three in one day is a perfect day: that day's piece comes out gold.

Winter Arc questions
How do I start my Winter Arc?
Download Mango Bites on iPhone or Android, set your goal, and join the Winter Arc from the home screen. Your 28 days start the day you join, and that first day already counts.
How much weight can I lose in a 28-day Winter Arc?
It depends on your deficit. At a steady pace of about 0.5 kg (1 lb) a week, 28 days add up to around 2 kg (4 lb). Mango Bites sets your green zone from your age, height, weight, activity and goal; you can preview your own numbers with the calorie deficit calculator.
What happens if I miss a day?
Any progress counts: meeting just one of the three goals still adds that day's piece. A day without any progress adds no piece, and that week can no longer raise your badge's tier. The challenge itself keeps going.
What do I get for finishing?
Silver chests on days 3, 10, 17 and 24, gold chests on days 7, 14 and 21, and on day 28 the Winter Arc badge, from bronze to diamond, plus the Frost frame to wear in your league.
Who is Mangi?
Mangi is the mango-shaped virtual pet that lives in Mango Bites. He eats the meals you scan, walks and drinks water with you, and his mood follows your day: sleepy before you log anything, zen on a perfect day.
Do I have to count calories by hand?
No. Take a photo of your meal and Mango Bites estimates its calories, protein, carbs and fat, then tells you whether you are still in your green zone.
Until when can I join?
You can start your Winter Arc any day until 1 March 2027. When your 28 days end, you can go on with a Winter Arc II.
