According to Ayurveda, Digestion plays a big role with your overall health.
Weak or unhealthy digestion can lead to weight gain, constipation, bloating, excess acidity, etc.
According to Ayurveda, the digestive fire (called agni) is highest and at a peak during lunch time hours between 10 am and 2 pm. During these hours your pitta dosha, which governs your metabolism and digestion is at its highest and at the same time the sun is at it’s strongest.
So, by eating your biggest and heaviest meal between these mid-day hours while your digestive system is working to its fullest, you can digest more easily and process foods to the fullest. Not to mention you have the rest of the day to burn off excess calories.
As the sun sets you should avoid eating heavy foods and large meals because your digestive fire has slowed. You should also finish all of your meals before 6 pm.
