How do Spices Help in Weight Loss?
The way we burn our calories is split into three categories: our metabolic rate, the physical activity we do and the energy utilised to digest food or dietary thermogenesis.
Dietary thermogenesis accounts for 10% of the total energy spent in a day.
Just like herbal drinks, spices raise dietary thermogenesis.
This further leads to greater satiety and breakdown of fat. Spices have been found to increase metabolic rate similar to caffeine and alcohol.
Capsaicin and capsinoids are active ingredients found in chilli and these are found to increase energy expenditure in humans.

These activate certain receptors in the body called Transient Receptor ion channels and TRPV1 and activation of these receptors reduces fat deposition.
Apart from helping in weight loss, these spices also help in improving metabolic health.

The spices have antioxidant and anti-inflammatory properties. They help in reducing insulin resistance, diabetes, hypertension, and high cholesterol levels.
