What do blood-glucose trials suggest?
A meta-analysis of six randomized trials in adults found reductions in fasting glucose, several blood lipids and diastolic blood pressure. However, studies varied substantially and were generally low quality, with limited participant diversity. The authors called for larger, longer trials. 1
Less chocolate now, less sugar later?
In a crossover study of 56 healthy young adults, a dissolving mint containing 4 mg gymnemic acids reduced chocolate intake over 15 minutes by about 21% versus placebo. That immediate taste effect does not establish lasting weight loss. 2
The longer test was less clear
A 14-day study in 58 healthy adults found no difference between groups in chocolate intake at the final visit or in reported intake across nine food categories. This limits how confidently the brief laboratory effect can be applied to everyday eating. 3
