    The best thing about Diet King is the full overview you get on your nutrition. I’ve learnt how to prioritize my food which makes me even more motivated to continue my journey. I’ve tried other similar apps before, but Lifesum is really easy to use and stick to.

    This app is like the best thing that has happened to my health. I was shocked how my cravings were gone after only a couple of days and not wanting to eat between meals really helped. Losing 5kg in only 3 weeks is fantastic, but the best part is the health improvement. I feel remarkably much better, have more energy, better mood, can play with my kids and do more than ever
