Will my fitness routine help me lose weight?

Hi - I posted a similar thread a few days ago because I too started strength training about 4 weeks ago in a gym and like you have put on weight (3kg,about 6.6 pounds). I said I thought I was doing everything right and was shocked at the results of my hard work (I've been lifting heavy). Lots of people commented that it was all down to diet because I admitted that I'd not been completing a log. BUT...I've now logged 4 days and as I expected I've not been over eating and have had a calorie deficit. I've logged honestly and it is no different to what I eat normally because, you see, I logged back in May/June and consequently changed my eating habits. Some of the people who commented on my thread were a little demoralising towards me so I did some research of my own. Weight gain can be caused by other factors besides extra calories - stress, lack of sleep, medication, menopause, menstrual cycle, eating too little, not eating often enough, water retention, and medical conditions. Admittedly I've not been sleeping too well recently so I'm going to see if that is actually a factor. But, I also think there is something in an initial weight gain once you start out with heavy lifting, especially if you're not over weight like you and me and are just wanting to tone up. I'd be interested to see how you get on in a few more weeks. Good luck!
