SATIETY. GLP-1.
THE RESEARCH.

Satiety is the feeling of fullness that lasts after eating. GLP-1 is a gut hormone involved in appetite regulation and the body’s response to a meal.

Protein and certain dietary fibers can stimulate the body’s own GLP-1 release. The studies below explain the evidence. A change in a hormone measurement does not automatically mean less hunger or less food eaten.

HUMAN MEAL STUDY

PROTEIN AND YOUR BODY’S OWN SIGNALS

In a randomized crossover study, eight healthy volunteers ate breakfasts high in protein, carbohydrate or fat, matched for calories, volume and appearance. The high-protein breakfast produced higher GLP-1 and PYY concentrations.

In everyday terms: changing what a meal contains can change the gut-hormone response after eating. In this small study, the hormone differences did not lead to a significant difference in how much participants ate at the next meal.

REVIEW OF HUMAN TRIALS

ANOTHER PART OF THE SATIETY PICTURE

Gut bacteria can ferment certain dietary fibers into short-chain fatty acids. These can signal to cells in the gut to release GLP-1. Fiber types differ, so their effects cannot be treated as interchangeable.

A 2026 scoping review examined 52 studies involving 1,085 participants. Some fibers increased GLP-1, but effects varied and greater satiety did not consistently accompany a hormone increase. Many studies were small and short.

Water-holding capacity, viscosity and fermentability describe different properties. Holding water is not, by itself, evidence that a fiber stimulates GLP-1. This review does not establish the response to INCHY’s fiber or show that protein and fiber have equal effects.

LABORATORY RESEARCH / IN VITRO

RESEARCH SHOWS

Researchers isolated peptides—small protein fragments—from hydrolyzed sacha inchi meal. Several inhibited DPP-IV in laboratory assays.

WHY IT MATTERS

DPP-IV is an enzyme that breaks down GLP-1. This research concerns the enzyme involved in that breakdown, a different question from stimulating GLP-1 release.

WHAT DOES THIS MEAN?

The tested peptides slowed the enzyme in a laboratory setting. This suggests a possible mechanism for further investigation; it does not show that consuming INCHY keeps GLP-1 active longer in the body.

WHAT THIS DOES NOT PROVE

This was not a human trial of finished INCHY. The preparations and concentrations tested cannot be assumed to match a serving of the product.

Isolation and identification of dipeptidyl peptidase-IV inhibitory peptides from Sacha inchi meal.

INCHY is a sacha inchi nutraceutical focused on satiety. Our proprietary process keeps protein and fiber from the same seed together in a functional ingredient designed for everyday foods and drinks.

The research explains the scientific interest in these components. It does not establish that a serving of INCHY increases GLP-1, prevents cravings or causes weight loss. Demonstrating those outcomes would require evidence relevant to the finished ingredient and serving size.

Keeping protein and fiber together is a feature of our ingredient. It is not evidence, on its own, of greater satiety per calorie or a stronger effect than taking protein and fiber separately.
