Slow release energy means that Skinnybik does not raise blood sugars quickly based on our clinical study (and other studies on lupin). This in turn means your energy levels and hunger will be more stable. This is not surprising since they are low carb, high fibre and protein and  contain several ingredients that have a low glycaemic index and glycaemic load (lupin flour, almond meal, oatbran, dates, erythritol and polydextrose fibre) see ingredients
