Grab some pistachios These little gems are one of the lowest calorie, lowest cholesterol and highest fiber nuts out there. And they help regulate your blood sugar. While things like chocolate will just spike your blood sugar and then make it drop so you’ll end up feeling worse later, nuts keep blood sugar levels steady. That means you’ll feel satisfied without the dramatic highs and lows.“The main thing with pistachios,” says Albers, “is to buy them in shells because that will make you slow down and eat them more mindfully.” Peeling them is therapeutic and meditative, giving you a sense of calm. Plus, you’ll end up with a pile of shells, so you can prevent overeating by tracking exactly how many you ate.
