Brief summary
The physical properties of a food product, such as its gelling properties in the stomach can influence how full a person may feel after its consumption. Decreasing appetite feeling through consumption of such a product with a low energy content may contribute to weight management. The study will assess if a drink with gelation properties in the stomach can reduce appetite and therefore contribute to weight management. This is a single-center, double-blinded, 4 arm cross-over randomized controlled study looking to enroll 24 adult participants. The study will be performed at the Clinical Innovation Lab (CIL), Nestlé Research, Lausanne. Enrolled participants will have 4 visit days after the screening visit. They will consume one of the test products, or control at each visit and complete the study assessments.
Interventions
DIETARY_SUPPLEMENTBeverage Variant 1 (low gelation properties)
The first interventional product for this study is a drink containing protein and fiber at a concentration 1. It will come in a ready to drink format for the participants.
DIETARY_SUPPLEMENTBeverage Variant 2 (medium gelation properties)
The first interventional product for this study is a drink containing protein and fiber at a concentration 2. It will come in a ready to drink format for the participants.
DIETARY_SUPPLEMENTBeverage Variant 3 (high gelation properties)
The first interventional product for this study is a drink containing protein and fiber at a concentration 3. It will come in a ready to drink format for the participants.
OTHERControl group (no gelation property)
The control product for this study is a drink containing protein and fiber. It will come in a ready to drink format for the participants.

Unstable diagnosed chronic conditions (such as hypertension, cardiovascular diseases, liver diseases, renal diseases, metabolic diseases). Unstable is defined as a change in medications in the past 3 months, or a change in disease severity in the past 3 months. As reported by participant. 7.
