Hi, some really good stuff on that list but also some complete diet myths! LOL IMHO of course
It doesn't matter when you eat, calories is calories. Think this goes back to the idea that you are less likely to be active later in the day but seriously, it absolutely makes no difference if you eat late at night. That said try and make sure your breakfast is a good one so that it kickstarts your metabolism
Organic foods don't make a diddly squat of difference to weight loss. Yeah they might be beneficial to your health but a calorie is a calorie is a calorie - whether it comes from a biscuit or an organic free range egg, you're always looking at using more calories than you are consuming = being in calorie deficit = weight loss
Walking is good but so are loads of other exercises. And if you can only manage 15 minutes don't worry, any exercise is better than no exercise at all, it doesn't have to be non stop hours worth of exercise. In fact there is a lot of evidence that says higher intensity shorter duration activities are really good for muscle growth and weight loss. However, any exercise is good and walking is a great way to do it
Re the tempting foods - I completely disagree with you there. I think a well balanced diet should allow you to have some of the things you crave, in moderation. When we deny ourselves all those yummy calorfic treats then we set ourselves up to fail eventually. I really believe you can eat anything you want in moderation. In fact I regularly have free days where I eat whatever I want. It means I never feel hard done by because I know that I can encompass any food I want to eat into my diet.
And lastly quantity. I eat loads. I mean seriously I eat lots and lots of food and I am never hungry. But I make sure I eat good stuff and I calorie count - I use thedailyplate.com and this has been instrumental in having a far healthier attitude to 'dieting' and what I am consuming.
I've managed to lose 17lbs following the things above as well as other things and I can honestly say I am loving it.
