I think that many of us have an interest in this topic and that a discussion thread would be useful for 'accountabililty' posts as well as tips and techniques, covering both diet and exercise as it pertains to weight loss.
There are lots of different methods out there. I'm hopeful we can be respectful of each other and not get into 'holy wars' about which way is best. The way that is best is the way that lets each one of us lose fat and keep it off. Of course civilized debate and disagreement is fine, and keeping open minds may lead us to methods that work better for us than the ones we have been using.
I just finished reading the book "The Obesity Code" by Dr. Jason Fung, and it's without question the best thing I've ever read about weight loss. I think it makes a strong case for there being other things at play in weight regulation than simply "burn less calories than you consume". There is a big difference in metabolic response (mainly insulin release) between, say, consuming 100 calories of broccoli and 100 calories of Skittles. The book says that too many calories in is the proximate cause of obesity but not the ultimate cause, which has to do with insulin regulation. So, you can definitely reduce weight by addressing the proximate cause (consume fewer calories) but the reason so many people can't keep weight off that they lose is because they are treating the proximate / apparent cause rather than the underlying disorder.
The book is a little "scienc-y" at the beginning and may bore some people but I found it fascinating because it sets the stage for what to do by explaining why it needs to be done. It also is not itself a diet, but a recommendation to change eating patterns (when/how you eat) to get the most metabolic benefit you can. It can be paired with various food plans.
