I've started a diet in VLCD fashion with a goal of losing at least 5 kg of mainly fat in a month. I'll mostly use a micronutrient-dense powder I bought in a pharmacy, and will complement it with additional protein and occasional normal food. VLCD is mostly recommended for the morbidly obese, and I'm just having trouble with the waistline and not overweight, so this should be interesting. It's three days in with about 1000 kcal intake, and I haven't experienced great difficulty yet. I've also had energy to exercise a bit.

I'm a doctor (yes, not a nutritionist), so I probably know most of the arguments and words of caution against this idea already, and know when to quit, so please don't bombard me with expressions of concern. I wouldn't recommend this to anyone else without reservations.

If anyone's interested, I'll post an update after a few weeks.
