How many times should you chew each bite?

Research published in PLOS ONE recommends chewing each bite 25-30 times. For harder foods like vegetables and nuts, increase to 35-40 times; softer foods can be reduced to 20-25 times.

What are GLP-1 and PYY, and how do they relate to weight loss?

GLP-1 (Glucagon-like peptide-1) and PYY (Peptide YY) are satiety hormones secreted by the small intestine. GLP-1 slows gastric emptying, while PYY sends a direct signal to the brain to stop eating. Slow eating significantly increases levels of both hormones, acting as a natural appetite suppressant.

How long should a meal take?

According to physiological research, the brain needs 15-20 minutes to receive satiety signals. Breakfast should take at least 15 minutes, and lunch and dinner at least 20-25 minutes to ensure your brain has enough time to register fullness.

What tools can help develop a slow eating habit?

The 'SlowEat' app on Apple Watch guides chewing rhythm through haptic feedback, offering Normal Mode, Decreasing Interval Mode, and Free Mode. Users don't need to count — just follow the gentle wrist vibrations to build a scientific slow eating habit.

Yes. Scientific research shows that slow eating extends mealtime, giving the brain the 15-20 minutes it needs to receive satiety signals, naturally reducing calorie intake by 10%-15%. Thorough chewing also increases Diet-Induced Thermogenesis (DIT), burning approximately 10% more calories during digestion.
