This pilot study aims to explore the potential benefits of consuming Greek Bottarga (grey mullet fish roe) in overweight, pre-diabetic individuals. Before initiating the crossover randomized controlled trial (RCT), the investigators will conduct a preliminary dose-testing study in five overweight and pre-diabetic adults.Participants will undergo clinical assessments before and after the dietary intervention to evaluate changes in metabolic health markers. Following this, the investigators will proceed with a randomized, controlled crossover trial involving 20 overweight and pre-diabetic adults. This main study phase will compare the metabolic effects of daily Bottarga supplementation to those of a calorically matched dairy product over an 8-week period, with a 2-week washout period between interventions. The investigators anticipate that Bottarga supplementation will lead to improvements in lipid profiles, inflammation, and insulin resistance, which could promote the use of sustainable blue foods as part of a healthy diet.
