Re: And now my turn,
My tips are:
Eat less, move more.
Your diet is not the food you eat when you are trying to lose weight, it is the food you eat all the time. You will not lose weight by trying to briefly change your existing food, you need to permanently alter the food you consume.
Arrange your diet so you are hungry when you are at work and asleep - work keeps you distracted, use tea and fruit as a further distraction, eat early in the evening so that you are feeling a bit peckish when you go to bed. It's not that eating late at night is bad for you, it's that if you are going to be hungry for 8 hours, its best to do it when you are unconscious as you will probably eat less.
Your weight is on a cycle. Don't get down on yourself until you understand your weight cycle. Always weigh yourself at the same time of day. You can lose/gain 3-6lb solely by dehydrating/over-hydrating yourself - don't.
Don't be too anal about measuring things. It's good to know roughly how many calories you are shoving down the pie hole, you don't need to weigh your fruit + veg. I've lost over 100lb, I've never calculated my BMR, TDEE nor weighed my food nor tracked my exercise nor recorded my daily weights. I measure my weight once a day, and record it about once every 2-3 months, to check on overall rates - that's it.
Low fat, low sugar, reduced and balanced carbs, slightly reduced protein. Anything you eat, think "is there something I can eat that is tastier than this and better for me?" and have that instead. Use NLP to change your thinking so that it is tastier for you.
Make eating a ritual. Eating an apple? Cut it up into 32 equal sized slices first. It will last longer, you spend more time thinking "Mmm. apple.", and it is a more satisfactory experience.
Most importantly, there is a human endocrine signal that most people call hunger. This signal developed when we were hunter-gathererers, and it lets us know that "hey buddy! we're going to need some food down here sometime soon. You'd better go hunting and gathering PDQ". Thing is, we don't need that signal anymore, food is everywhere, and so we treat that signal as "hey buddy! go eat something!". Learn to tolerate this signal. When you get it, look over to the fridge full of food and say "job done, done my gathering". Don't eat something until you do get the "go eat something" signal, which is unmissable when it gets there, or it is time to eat something.
I think the last one is the most crucial part of any will power driven exercise - identify the feeling, learn to tolerate/love the feeling, and live with it.
