To lose weight, it is essential to chew food well.  This is the first step to adopting a healthy diet.  Chewing is essential because it marks the start of digestion and it is the only step that we consciously control.
Some benefits of chewing:

Chewing food correctly allows for better digestion and assimilation of nutrients.

Insufficient chewing of food causes intestinal bacteria to ferment it, leading to bloating.

Poor chewing promotes inflammation and can lead to food intolerances.

Proper chewing reduces the risk of diseases such as diabetes, obesity, autoimmune diseases and chronic fatigue.

Chewing properly also allows you to savor foods more and appreciate their different flavors.

Taking the time to chew allows the brain to receive satiety information, which helps control the quantities ingested and promotes weight loss.
