Why
  1. The study's listed conditions name Obesity, a narrower term within Overweight.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This study aims to assess the effect of stevia extract on postprandial glucose and insulin levels in overweight and obese adults when compared to sugar and water.

Read the detailed description

The study is a three-arm crossover trial involving participants attending the Lab on 3 different occasions (separated by 3-5 day washout period), where they will be administered water, sugar solution (65g), water and stevia extract (5g) solution. The solution will be followed by a consumption of a fixed meal (after 30 minutes). Breakfast will be standardised. Capillary blood glucose will be collected every 30 min until 2 hours post meal. Venous blood samples will be collected before the intake of the solution and at 2 hours after meal intake.

Inclusion criteria

  • Age 18-65 years
  • 27-40 Kg/m2
  • Males and females

Exclusion criteria

Exclusion Criteria:

  • Athletes
  • Pregnant or breastfeeding women
  • Patients with chronic disease (diabetes, CVD etc...).
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.

What researchers measure

Primary outcomes

  1. Postprandial glucose levels

    Change in glucose levels two hours after the administration of a fixed meal

    Time frame: Capillary blood glucose will be measured two hours after the administration of a fixed meal.

Secondary outcomes

  1. Postprandial insulin levels

    Change in postprandial insulin levels two hours after the administration of a fixed meal

    Time frame: Postprandial insulin levels will be measured two hours of the administration of a fixed meal

  2. Area under the curve (AUC) for glucose

    Changes in AUC for glucose throughout the intervention

    Time frame: Capillary blood glucose levels will be collected 6 times on each visit before the intake of the solution until 2 hours post lunch

  3. Subjective feelings of satiety

    Visual analogue scales

    Time frame: VAS will be collected 6 times on each visit before the intake of the solution until 2 hours post lunch.

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 10, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
