Tag: Metabolism and fasting

According to the Dietary Guidelines for Americans, adult women and men need an average of 1,800 to 2,400 and 2,000 to 3,200 calories per day, respectively, making 1200 a low-calorie intake for most. Combining this restrictive intake with intermittent fasting is a concern for many, raising questions about its safety and sustainability.

According to a study published in 2011, individuals on a restricted-calorie diet had a significantly lower core body temperature compared to those with a regular intake. This drop in body temperature explains why you may be asking, "Why am I so cold when I'm fasting?"

According to a study published in the journal 'Cell Research,' during caloric restriction, the body reduces heat production to conserve energy, leading to a temporary drop in core body temperature. This fundamental physiological response is the primary reason why you may ask, "Why am I cold when I don't eat?"
