Using Lifesum is really simple. The first thing you have to do is select your age, weight, and height. Lifesum will give you approximate information on the nutritional values you should be ingesting on a daily basis. For someone that is approximately 5' 7'', this means around 2,000 calories a day.
Once you have all your information in the app, it's time to start using it. Lifesum has a huge food database that lets you add any type of food you've eaten. If you've had some milky coffee and toast for breakfast, for example, you just have to add that in the app, which will only take about 30 seconds.
The best thing about Lifesum is that it lets you create recurring profiles, so if you usually have the same thing for breakfast, you can create a profile for it and add it with just a touch.
Lifesum is a really useful app to help you find a healthier lifestyle and lose weight, too. Seeing how many calories you ingest every day can be a good incentive to control yourself better.
