Hence why it takes so long to genuinely lose weight without affecting your energy levels and mood. I never try to lose more than 1kg (2.2 lbs) per month, so based on your figure, that would be a deficit of roughly 250 calories/day, which in my experience is sustainable, but definitely requires some discipline. A 1600 calorie/day deficit is totally unsustainable.
I think genuine weight loss requires a lot of patience and a long-term mentality. Your diet needs to be sustainable for the rest of your life - which for me rules out any commercial diet plan that targets rapid weight loss.
