A nutritional intervention study is proposed to evaluate the association between the consumption of A. domesticus (insect protein) powder and the effect on insulin resistance and the microbiome, in order to generate personalized nutrition strategies through its analysis with artificial intelligence. This study is expected to involve 120 healthy volunteers between 18 and 65 years old, with or without insulin resistance, who will be recruited by IMDEA-Food. This is a 12-week nutritional intervention study, so you must come to Institute IMDEA-Food for a first screening visit (V0) and, if you meet the study inclusion criteria and are still interested in volunteering for the study, you will be informed about the study, sign the informed consent form and be scheduled for 2 more visits (V1 or initial zero-time, and V2 or final) at IMDEA-Food\'s facilities.
In visit 1 (basal visit), the participant will provide a stool sample (for microbiota analysis), a fasting blood sample (for biochemical, genetic, epigenetic and metabolomic analysis) and then go to the nutrition consultation where medical history data and lifestyle habits will be collected, a nutritional assessment will be made and the completed questionnaires will be corrected. In addition, they will be provided with continuous glucose monitoring sensors and an activity wristband to record lifestyle patterns. The glucose sensors will be used for the first 14 and last 14 days of the intervention. In addition, all participants will be provided with the required amount of product until the next visit, as well as how to consume, store, and ideas for consumption. In addition, a balanced (normoprotein) and varied diet and physical activity guidelines will be explained. In the second visit (final), the participant will again submit a stool sample (for microbiota analysis), a fasting blood sample will be taken (for biochemical, epigenetic and metabolomic analysis) and then they will go to the nutrition clinic where a nutritional assessment will be made and the completed questionnaires will be corrected. In addition, the glucose sensor and the activity bracelet will be removed. During the intervention phase of the study, participants will be able to come to the center for the collection of more product as well as for the review and troubleshooting of any problems with the sensors that may arise. In turn, halfway through the study (6 weeks), a telephone survey will be conducted to participants to avoid travel, in order to assess the degree of adherence and possible adverse effects.

The study will have two arms, the functional group with A. domesticus powder (n=60) and a placebo group that will take a vegetable protein powder with a similar macronutrient composition (n=60). This population will be classified according to sex and BMI, and their nutritional-metabolic status (insulin resistance or not). The study will include analysis of phenotypic data collection (medical history, lifestyle, diet, etc.); biochemical data: glucose, lipid, iron profile, blood count, and analysis of inflammation markers; genotyping, epigenetic analysis (methylation and mi-RNAs), targeted metabolomics (glycome and tryptophan) and metagenomic analysis of stool (16s rRNA sequencing for taxonomic identification study). Using continuous monitoring devices (glucose monitoring using a sensor and physical activity using an activity bracelet), lifestyle parameters (physical activity, circadian rhythms, sleep, stress, etc.) and blood glucose will be evaluated.
insulin resistance (HOMA)
The primary endpoint will be changes in insulin resistance values after 3 months of intervention.
Time frame: 3 months
