The Effects of Oral Glucose Compared to Sweetener Drinking on Hormonal/Metabolic Responses

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).

Also, they will record their macronutrient\\caloric consumption during the 24 hour following the test.

Inclusion criteria

• Adults, healthy, men and women, ages 25-35 years, without any chronic illnesses.

Exclusion criteria

• Family history of diabetes or overweight with BMI> 27
• Use of drugs who can influence the glucose metabolism (exp: glucocorticoids).
