According to research, French people spend an average of 130 minutes at the table daily, typically enjoying a meal slowly for 30 to 50 minutes. In contrast, Koreans’ average meal time per day is about 15-20 minutes, with each meal lasting roughly only 5 minutes! The French take their time with meals, allowing enough time to feel full. This leisurely eating habit reduces overeating, aids digestion, and positively impacts stomach and gut health, while also helping with weight management. Inspired by the healthy eating habits of the French, Chewell introduces the concept of β€œFrench Time Eating Habits.” Chewell offers a timer feature that provides alerts to encourage users to savor their meals slowly and chew thoroughly. The timer gradually adjusts to help users eat at a slower pace, and after each meal, they can view a report showing their eating pace and any changes. Practice β€œFrench Time Eating Habits” with Chewell and create a relaxed, healthy eating habit!
