The Role of Diet and Hormones on Taste: Low Carb Compared With Low Fat Study Findings
Background
As obesity rates escalate, weight-loss interventions, including low-carbohydrate (LC) and low-fat (LF) diets, have become popular. Although both diets promote weight loss, the effect of LC and LF diets on taste preference and sensitivity is less well understood.
Objective
In this study, we sought to (1) compare sweet and salty taste detection thresholds and preferences following a 2-wk ad libitum LF diet compared with an LC diet and (2) determine whether sweet and salty taste detection thresholds and preferences were associated with body weight, body mass index, blood pressure, taste relevant taste substrates (sodium and total sugar), intake, and hunger and satiety hormones (i.e., ghrelin, leptin, peptide YY [PYY] and glucagon-like peptide-1 [GLP-1]).
Methods
We analyzed and compared taste preference and detection after ad libitum, randomized, controlled inpatient feeding study (n = 18) comparing LC (10% carbohydrate, 75% fat, and 15% protein) and LF (75% carbohydrate, 10% fat, and 15% protein) diets. Taste measures and hormone levels were measured at the end of each dietary period.
Results
We found no significant differences in taste measures between the LC and LF diets. However, we did observe a negative association between salt preference and leptin levels during both LC (rs = 0.59; P < 0.01) and LF (rs = −0.47; P < 0.05) dietary period. Salt taste preference was also negatively correlated with GLP-1 after the LF diet (rs = −0.61; P < 0.01). The results of this post-test study suggest that taste measures do not differ between 2-wk LC and LF diets.
Conclusions
The results suggest that taste measures do not differ following 2-wk LC and LF diets. However, the relationship between taste preference and hunger and satiety hormones should be explored further.
