Study Overview
Brief Summary
The goal of this study is to determine the hormonal/metabolic reponse to ingestion of sugar compared to consuming artificial sweetened drink, and to evalute macronutrient consumption 24 hours post ingestion of the drinks.
We hypothesize that artificially sweetened (AS) consumption will lead to a relatively similar hormonal/metabolic responses as glucose consumption and therefore to secondary rise of caloric intake.
Detailed Description
During the last two decades, the prevalence of overweight and obesity doubled. at the same time, individuals have increasingly turned to artificially sweetened (AS) foods and beverages in an attempt to lose weight, or control it.
several studies have found that there may be a connection between artificially sweetened food and beverages consumption and paradoxical weight gain and increased incidence of metabolic syndrome. the causal relationship between AS use and weight gain haven't been proven yet.
The participants will be invited to 2 meetings in which they will consume, in a randomized double blind way:
- A beverage containing 75 gram glucose
- A beverage containing 0.42 gram artificially sweetener (Aspartame, similar sweetness level)
During each meeting, the participants will drink the sweetened drink followed by blood work, as done in oral glucose challenge or tolerance test (OGTT / GTT).

Arms & Interventions
Artificial sweetner
participants will consume a beverage containing 0.42 gram artificial sweetener (Aspartame) During each meeting, the participants will drink the sweetened drink followed by blood work, at 0, 30, 60, 120, 180 minutes.
Also, they will record their macronutrient\caloric consumption during the 24 hour following the test.
Intervention: sweetner (Other)
Oral glucose tolerance test
The participants will consume a beverage containing 75 gram glucose During the meeting, the participants will drink the sweetened drink followed by blood work, at 0, 30, 60, 120, 180 minutes. Also, they will record their macronutrient\caloric consumption during the 24 hour following the test.
Intervention: glucose (Other)
Outcomes
Primary Outcomes
Hormonal response
Time Frame: 3 hours
All the participants will be checked for level of: insulin, glucose, adrenalin norepinephrine, dopamine, catecholamines, cortisol, ghrelin, leptin, IGF-1 GH- and other related hormones before consuming the drink (time 0), and 30, 60, 120, 180 minutes after. The participants will be under medical supervision throughout the examination, including HR \& BP montoring, and until 1 hour after
Secondary Outcomes
- food questionnaire(24 hours)
