But how a lot do we actually want medicine like Ozempic? Can we use meals as medication to interchange them?
How does Ozempic work?
The energetic ingredient in Ozempic is semaglutide, which works by inducing satiety. This feeling of being happy or “full”, suppresses urge for food. This is why it really works for weight reduction.
Semaglutide additionally helps the pancreas produce insulin, which is the way it helps handle kind 2 diabetes. Our physique wants insulin to maneuver the glucose (or blood sugar) we get from meals inside cells, so we will use it as power.
Semaglutide works by mimicking the function of a pure hormone, referred to as GLP-1 (glucagon like peptide-1) usually produced in response to detecting vitamins once we eat. GLP-1 is a part of the signalling pathway that tells your physique you’ve got eaten, and put together it to make use of the power that comes out of your meals.

Can meals do this?
The vitamins that set off GLP-1 secretion are macronutrients – easy sugars (monosaccharides), peptides and amino acids (from proteins) and brief chain fatty acids (from fat and in addition produced by good intestine micro organism). There are a lot of these macronutrients in energy-dense meals, which are typically meals excessive in fats or sugars with a low water content material. There is proof that by selecting meals excessive in these vitamins, GLP-1 ranges may be elevated.
This means a nutritious diet, excessive in GLP-1 stimulating vitamins can enhance GLP-1 ranges. This may very well be meals with good fat, like avocado or nuts, or lean protein sources like eggs.

The receptors that detect it may additionally be much less delicate or there is likely to be fewer receptors.
