  1. Weight Loss is a broad heading, used only when no more specific condition is named.
  2. The study's title name Obesity.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

To the best of our knowledge, the effect of pasta consumption within a hypocaloric Mediterranean diet has only been scarcely explored yet. Therefore, a two-parallel group dietary intervention was carried out to investigate if pasta consumption could affect the BMI change in obese patients. The primary outcome was the loss of at leat 8% of the initial body weight in the first 6 months. Anthropometric and body composition (from bioelectrical impedance analysis - BIA-) measures were collected every month for the first 6 months and after 1 year. In addition, dietary information was collected at baseline and after 3, 6 and 12 months through a 7-day carbohydrate food record and a 24-h food recall. Blood samples were collected at baseline and at 6 and 12 months to assess: glucose, insulin, Homeostatic model assessment for insulin resistant (HOMA-IR) index, total cholesterol, low-density lipoprotein, high-density lipoprotein, and uric acid. Furthermore, the perceived quality of life was investigated through the 36-items short form health survey (SF36) questionnaire.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

  • Experimental
    High Pasta

Interventions

  • BehavioralHigh Pasta

    Participants received a personalised diet program considering their food preferences and eating behaviour, based on the Italian guidelines for a healthy and Mediterranean diet and were encouraged to maintain their habitual consumption of pasta (at least 5 times/week). To encourage participants to prepare healthy meals by using high-quality ingredients, participants were provided with a recipe book and dietary guidelines and recommendations.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2015 to primary completion in Dec 2017, 25 months.

Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's 25 months is close to that.

Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 4, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
