Insulin resistance and diet associations with food cravings

Krista Fieselmann, Purdue University

Abstract

BACKGROUND: Individuals with insulin resistance (IR) have been suggested to have more food cravings than those without IR, however little research has been done in this area. METHODS: We analyzed data from healthy, non-smoking, weight stable adults (aged 18–58 y; BMI 19-35 kg/m2) and with reported energy intakes (EI) plausibly (within ±25% of energy requirement). Cravings were assessed by questionnaire. Diet was assessed by 3 multiple pass 24-hr recalls. Cravings in these analyses were controlled for %body fat, age, sex, race, activity energy expenditure, restraint and hunger. RESULTS: Associations of HOMA2-IR with cravings were observed only in plausible reporters of energy intake, with craving frequency per day and ease of ignoring cravings. Glycemic load was inversely related to ease of ignoring cravings, in our model with HOMA2-IR. Increased protein consumption associated with lower odds of having a high craving frequency per day. CONCLUSIONS: The associations of HOMA2-IR with cravings was inverse our hypothesis, suggestion a more psychological origin of cravings than physiologic. Diet was associated with some cravings variables, which suggest that lower glycemic and higher protein diets may suppress eating behaviors like cravings, or that individuals who have lower cravings choose lower glycemic and higher protein foods. These results also point out the importance of isolating the plausible reporters of dietary intake from the total sample.
