Great App for Calorie Management


I have been using this app for 4 months and have found it very helpful for calorie tracking and weight loss. The food database is extensive, and scanning in barcodes makes tracking quick and easy when you are very busy. The user interface is intuitive, and the calorie budgets are realistic and sustainable as long as you are choosing a healthy rate of loss for your current weight. As with any app like this, it is a tool and you should be smart about making sure your plan is safe and healthy. I bought a premium subscription after using the app for a few months, which adds more info about nutrient profiles of your food and trends in your habits that contribute or take away from your progress. I can see myself using this app for a long period of time far past when I reach my goal. I have tried going off tracking in the past after weight loss, and have found that the good habits with healthy eating you gained slip away quite quickly in the face of the stresses of everyday life. I would encourage people to try this app for a few weeks and see how you like it; this sort of thing is all about personal preference. You should look for something that is sustainable in the long term as opposed to a ‘diet’, since the changes you make should be lifelong if you hope to keep up your healthy results long term. You may or may not want premium; many people find the free version is more than sufficient.

Loseit! + discipline = weight loss


For 3/5 of my life, due to severe injuries and illness, I've been waffling the border of overweight and obesity. For the first time in almost a decade, my health was stable, so I figured I'd make dedicated effort over the summer of losing weight (I was 220lbs/100kg).
Loseit! was an app recommended by my pedometer app, and I kind of got it on a whim. 😅 I love to eat, have my Dad's sweet tooth, and am (more than) a bit lazy (ok, just highly unmotivated)... none of that is good for weight loss, so every bit helps, right?
Well, I got a scale, started counting calories with the app (the free one, not premium), and went walking or biking depending on weather. It is a bit over 100 days later, and I've lost 50lbs/23kg. I'm going to keep going another 20-30lbs/9-14kg, though at a slower rate for the holidays. 😉
Self discipline is really important to how successful you'll be, though. If you don't log everything (I know it is inconvenient/a pain/insert opinion here), but not doing so is pretty much setting yourself up for failure. I'm not saying 'don't eat sugary foods/that one food that's bad for you that is a guilty pleasure', that would be hypocritical of me (again: I love food & have a huge sweet tooth. There is no way I'm ever not going to eat what I want). I'm saying that if weight loss is important to you, you won't cheat yourself by fudging your log. Be brutally honest with yourself. It helps put what you're eating into perspective. 😁
