According to Ayurveda, digestive fire or Agni guides proper functioning of our digestive system. Hence, it is responsible for all functions related to food metabolism, assimilation, and nourishment.

Role of Brain in controlling the Digestive Fire and Food Cravings
You may have heard the saying “digestion begins in the mouth,” but it actually starts in the brain! And sometimes, despite being super full, you still feel having some room for that delicious food, which you just saw or sensed the aroma of! This is also how your brain manipulates your hunger and cravings.
Our metabolism and digestive system works in a series of steps where brain begins to prepare the body for the meal that we are about to eat. As we sense food through our eyes, nose, or even hear about certain food items, our body responds with certain actions:
- Saliva production increases.
- Stomach begins to produce enzymes and acid.
- Liver and gall bladder get ready to release bile.
In addition, your Circadian rhythms control the flow and level of different hormones, which further define your appetite and cravings. Hence, if you usually follow a routine to your meals, you will always get hungry at the same time – and this is actually a very good indication that your body and mind are in sync!
Ama – Toxins building up in the body
If you have diminished Agni – digestive fire within you, then the food remains undigested. The undigested food is sticky in nature and is called “Ama”. Ama is the primary reason behind modern lifestyle physical and mental health issues.
Ama is deposited in the body within excessive fats leading to weight gain, weakness, lowered agni and hence slow metabolism, and further deposition of fats.
Ama is caused due to inappropriate eating habits and careless lifestyle. For a proper removal of Ama “Toxins” from your body, you need to adopt a holistic lifestyle with physical activity. Also ensure that you are consuming foods that provide you with essential micronutrients, antioxidants, and fiber.
