To set realistic expectations, it’s useful to know the common mechanisms by which natural fat-burning supplements claim to act:
Thermogenesis: Increasing heat production in the body slightly raises calorie burn. Ingredients that stimulate thermogenesis typically act on the nervous system to raise metabolic rate.
Appetite suppression: Helping reduce hunger and cravings leads to lower calorie intake. Some botanicals and amino acids can influence satiety hormones or neurotransmitters that regulate hunger.
