During weight loss, carbohydrate‐restricted diets produce favorable metabolic effects; however, few studies have evaluated the potential role of the type of food consumed in these fat‐rich diets. Eighteen subjects (BMI=30–38) consumed three diets in a randomized, balanced cross‐over design for 4 weeks separated by 4‐week washout periods. Diets were designed to provide 1600 kcals for women (n=14) and 2200 kcals for men (n=4) to promote weight loss. Diets included approximately 61% of energy from carbohydrate (CHO), 18% protein (PRO), and 21% fat for the low fat (LF) diet and 10% CHO, 30% PRO, and 60% fat for the very low carbohydrate (VLC) diets. One of the VLC diets was primarily plant and mushroom (170 g/d) based (VLCPM) and the other provided more fat and protein from animal foods. Significant main effects for decreased (p<0.05) systolic and diastolic blood pressures (BPs) for the trials were detected. Post‐hoc examination with paired t‐tests revealed that only within the VLCPM trial were the decreases in both BPs statistically significant (p<0.05). The change in systolic BP during the LF diet bordered on significance (p=0.065). It is unclear whether the more robust decreases in BP after consuming the VLCPM diet is due to slightly greater loss of body weight or a diet component. Further investigation into the potential influence of plants and mushrooms on BP is warranted. Supported by the Mushroom Council.
