If you’re following the keto diet, this handy little breathalyser helps you spot when you’re burning fat as your main fuel source, simply by measuring the concentration of ketones in your breath. The tests are quick and easy, your results sync to an app and, over time, allow you to change the effectiveness of your workouts and customise your diet to prioritise weight loss. It can also help spot if you veer too far into potentially harmful ketoacidosis. Features ★★★★★ Innovation ★★★★★ OVERALL ★★★ ★
