Why can't I lose?
 

Last Monday, I started a diet where my calorie intake is under 1500. Then I decided to go swimming three times a week for around 30-40 mins. On the days when I did not go swimming, I went on the dance mat for 30mins and did some weight lifting exercises. Since Wednesday, I have not lost anything, despite having been strict and exercising. I don't know what I'm doing wrong and I feel like I'm wasting my time; I just wanted to lose 21 -28 pounds over Summer and now I feel so far away from even losing 1 stone.

Give it more time, please. It will take time to lose, and even if you don't see any progress in the first week, if you stick to it you'll find that some weeks you lose more than you expect/hope, and other weeks you lose less. As long as the average is losing rather than gaining, you're doing well.

When I'm truly sticking to my plan (instead of faffing around with it like I did last week) I lose every two weeks. I may drop a tiny bit one week but the next week 2-3 lbs will go. I have no idea why that is but that's how it goes for me. Helen is right, you're being impatient (totally understandable). Why don't you try going for two weeks without weighing and see what happens - I bet you'll be pleasantly surprised.

in addition to the comments above

are you eating enough? depending on your weight it might not be enough (or too much) ... watch the (processed) sugar in foods... i have found cutting it out i loose easier... e.g i thought i was being gd haivng weetabix.. but its got lots of sugar in ... etc..

keep a food diary... it supprising what you "forget" you have eaten.. it all counts!

and like above.. as long asyour not gaining keep at it !...

HI LOu! and Hi to marmite! Just wanted to add my 10 pence worht that writing dfown what yu eat is a very good idea.
