10 Signs You Are Not Eating Enough

5. Always cold

Constantly feeling cold is symptomatic of many problems. One of these issues is poor overall health and poor diet, which could mean you're not eating enough calories. Our bodies require an adequate number of calories to create heat and maintain a healthy, comfortable weight. Studies suggest restricting calories may lower core body temperature and therefore make you feel cold. In a six-year controlled study, participants who consumed fewer daily calories had a lower body temperature than those who ate more calories.
