I'm going to buck the trend, LOL. Looking at your planner, I don't think you're doing anything wrong at all. Yes, you could try changing your menu choices - but the benefit from doing that would mainly be to stop yourself from getting bored and throwing in the towel.
One of the benefits of having done every diet under the sun (and oh boy, I think I can just about say that I have!) is that I can say, with absolute certainty, that weight loss isn't linear. No matter what diet you're on - even if you're on something like LighterLife and consuming <600 calories a day - there will be weeks where you don't lose very much weight. It's incredibly frustrating, because we're all sold on the idea that if we take fewer calories in than our body needs for daily living, we
should lose weight. And we do - over time. But not in the same amounts every week.
Even if you were to eat exactly the same foods in exactly the same amounts for 4 weeks on the trot, one of those weeks you might lose 3 pounds, two of them you might lose 2 pounds and one of them you might lose nothing. I know, cos I've done it.
Why??
Well... (1) the human body is not a machine - well, not an efficient one, anyway
(2) levels of water in the body fluctuate - remember, the scales aren't just measuring fat loss - they measure everything. So although you might have lost fat, because you're retaining water, the fat loss won't show up at the scales
(3) Stress. Nowhere near enough research has been done on this one, IMHO. But it is known that increases in the stress hormone cortisol affect the body's ability to burn calories efficiently. Perhaps not surprisingly, studies have shown that people who are overweight have higher levels of stress, sigh...
So, for what it's worth, I think you should carry on doing what you're doing. It's working - okay, maybe not as quickly as you'd like - but it's working. Successful dieting is all about mind games, I've discovered. Don't let your mind trick you into the idea that you're not doing brilliantly. Because you are!!
