Numerous functional foods have been examined for their potential as weight-loss agents. To evaluate the future of functional foods, the AECES model has been developed to verify the following: Acceptability, Ease of formatting, Cost-effectiveness, Efficacy and Safety. The goal of this review is to assess three oil-based weightloss functional foods, including: conjugated linoleic acid (CLA), diacylglycerols (DAG) and medium-chain triglycerides (MCT), in terms of the AECES model for consumer acceptability. First, CLA is an overall poor AECES model due to its weaknesses in the efficacy and safety aspects since most of the evidence of CLA is based on animal studies. Secondly, oils rich in DAG, specifically the 1,3-isoform, have an appropriate AECES model. Although, the efficacy still needs more research to determine the exact mechanisms of action for DAG-rich oils. Thirdly, MCT oils exhibit a good AECES model; nevertheless, the long-term efficacy of MCT needs to be further explored. The capability of these three functional oils as effective anti-obesity agents is substantial, yet further investigation should be conducted to determine the missing gaps in research and to accomplish satisfactory AECES model for market acceptance.
