Study summary

The aim of this study is to examine a novel weight loss formula with and without common stimulants on anthropometry and indices of cardiovascular disease risk.

Read the detailed description

Obesity remains a problem for overall health and risk for cardiovascular disease worldwide. While dietary modification and increased levels of physical activity remain steadfast recommendations, alternative strategies related to supplementation remain an interest for the general populace and medical communities. A potential objection to the use of dietary supplements is that they often contain stimulants designed to increase metabolism. However, consumers and health practitioners alike are wary of such formulae; hence, the continued investigation of non-stimulant supplements is warranted. Therefore the aim of this study is to examine a novel weight loss formula with and without common stimulants on anthropometry and indices of cardiovascular disease risk.

Inclusion criteria

  • (BMI) between 25 and 34.9

Exclusion criteria

Exclusion Criteria:

  • Recent history of weight change (+/- 10 lbs. within the past 3 months)
  • Uncontrolled metabolic disorders
  • Uncontrolled cardiovascular disorders
  • Currently taking prescription medications ( is allowed)
  • Currently taking dietary supplements for weight loss
  • Pregnant or plan to become pregnant
  • Have an intolerance to caffeine or other natural stimulants
Terms in these criteria, in plain language(2)

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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 Jun 2017 to primary completion in Mar 2018, 9 months.

Of 670 non-industry interventional studies with no phase under Weight Loss, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 45. This study's 9 months is below that.

Counting every sponsor, half of 729 studies reached it within 24 months; a quarter within 11 and three quarters within 43.

How these figures are worked out, and which studies are left out of them.

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 Sep 10, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
