I started my diet a couple of weeks ago, and a couple of day...

I started my diet a couple of weeks ago, and a couple of days ago got a new digital scale to replace the old manual one. It weighed me about 5 pounds heavier. I am really discouraged and don't know which of the scales is likely to be more accurate.
I feel like I have gained and not lost weight. (according to the manual scale, I have lost some)
What should I do?

While digital scales can be more accurate, the increase of 5lbs isn't necessarily true. Different scales can vary, so don't get discouraged. Instead ensure that when you do your weigh in you use the same scale each time (and for best results the same time of the day, most professionals and diet plans suggest doing so in the morning, after a BM).

So basically use the results from the digital scale that you now have, but base your progress using the first digital way in as the starting point. If you still aren't finding the results you'd like, you may have to reassess your diet. However, you should remember that muscle weighs more than fat, so if you've added additional weight training it can seem as though you aren't losing weight even though you are losing fat. Don't judge everything by the "magical number" on the scale.

Trust the digital scale. You still lost weigh, you were probably just heavier than you thought. I did the same thing. Ever go to the doctor and step on their scales. Now that is depressing!
