Week Trial in Healthy Adults.

Purpose
To investigate the effects of daily stevia consumption for 12 weeks on glucose response, body weight, and energy intake in healthy adults with normal BMI.
Methods
The study randomized 28 healthy adults aged 18-40 with normal BMI into a stevia group (n=14) or a control group (n=14). The stevia group consumed stevia drops twice daily before meals over the 12-week study duration. The control group did not change their dietary habits. At baseline and week 12, glucose and insulin response to an oral glucose tolerance test was measured. Additionally, prospective food records assessed body weight and energy intake at weeks 0, 6, and 12. Physical activity and appetite questionnaires were also administered throughout the study.
Findings
The 12-week study showed no significant differences in glucose or insulin response to the oral glucose tolerance test between the stevia and control groups. However, the stevia group maintained body weight, while the control group gained weight significantly. This aligned with a significant decrease in energy intake in the stevia group that was not observed in controls. The changes in body weight correlated with the changes in caloric intake. There were no differences between groups in physical activity levels or macronutrient composition. Subjectively, the stevia
group reported decreased appetite and food cravings compared to the control group.
Questions:
1.
What mechanisms could explain the potential effects of stevia on appetite and energy intake observed in this study? The authors suggest effects may be mediated through sweet taste receptors, but are there other potential mechanisms that might reduce appetite or food intake with stevia consumption?
2.
What is the potential for stevia to support body composition goals and fat loss in client athletes? The weight effects in this study were relatively small over 12 weeks. But could stevia contribute meaningfully to programs focused specifically on fat reduction or improvements in body composition like gaining muscle and losing fat?
3.
How could findings related to lower appetite and cravings translate to benefits in client dieting practices for competitions or weight cuts? The subjective appetite effects suggest
potential applications for stevia to help adhere to the strict dieting required leading up to bodybuilding, physique, and other competitions where athletes need to reduce calories and make weight. Real-world insights would be valuable.
