But it's still not a diet

Three weeks in, and the 5:2-thing seems to be working. For the first time in... 10+ years, I'm now under 120 kgs - even if just under - and it gets easier and easier to not eat throughout the two days - until dinner. By taking in all 600 kcal (100g ground beef and two fried eggs along with salad) in one sitting, I am full when I go to bed and I therefore don't overeat the next day.

Even better, I've slimmed down somewhat as seen here:

I've still got lovehandles, and I don't quite know where to put my hands, but it could be worse.
