Let me share some things I've learned about good health and effective weight loss/control.
It's a long-term journey:
Good health (which includes a healthy body fat composition) is a lifelong journey. Don't get impatient or frustrated. It's great that you're looking for ideas and things to try, but remember that you are in this for the long haul, and two weeks is a short time. I haven't tried a ketogenic diet, but I eat a healthy vegetarian diet, and try to keep the carbs a little low, and the fats a little high. It doesn't sound like you are doing anything wrong, but subjectively speaking your approach sounds difficult and complicated. It'll take you months to get to where you want to go, and your strategy has to be something you can keep up for months. If keto works for you and is sustainable, go for it. If not I would suggest mixing intermittent fasting with "eat food, mostly vegetables, not too much" on your non-fasting days, combined with intermittent fasting.
Fasting is good for you
Don't believe anyone who tells you that fasting is unhealthy or dangerous. There is a large and growing body of evidence that fasting is both safe and effective, and has a large body of positive health benefits. If you are going to do longer fasts (over a week say), you may want to take a multivitamin and mineral supplements, but fasting has been a part of the human experience and human culture for millenia. Unless you are malnourished or have some complicating medical condition, fasting isn't just safe, it's good for you.
I recently completed a seven day fast which I intend to repeat years after reviewing the pretty compelling evidence that doing so dramatically reduces your chances of getting cancer. The evidence is growing that fasting reduces the probability of dementia and Alzheimers as well.
For an excellent survey of the health impacts of periodic fasting and its use for weight loss, I would strongly recommend "The Complete Guide to Fasting" by Jason Fung and Jimmy Moore. It's an extremely well researched and data grounded book, while still very approachable to the lay person. I found it informative and motivating. Dr Fung has a pretty large online presence and you might find it helpful to watch some of his videos.
Fasting isn't just an effective weight loss strategy, it's really healthy.
Listen to your body
Checking the scale regularly is a good way to measure progress, but it's not the only way, and it shouldn't be your only metric. How are you feeling? If you're in the middle of a fast it's normal to be hungry, and in the first couple of days of a fast it's common to be tired or irritable, but those shouldn't be chronic experiences. In my seven day fast I found the third day really hard, but the fifth through seventh days I felt great. I also notice my skin clear up and soften and my joint aches disappear, both of which were very pleasant surprises.
There are physiological reasons you plateau
There seems to be real tendency for the human body to attempt to maintain a "set-point weight". If your body is used to being 95 kg, it's going to have physiological responses which try to keep it at that weight.
Okay, so what does that mean about your frustration?
Well, you lost 4kg and now you're plateauing for a while... I have read that it's typical to shed excess water during a fast. In one 4 day fast, I lost a kg per day, and regained ~3.2 kg when I broke the fast. My seven day fast was similar: 3 days of 1kg per day weight loss, followed by .2 kg per day, and then regaining a couple kilos after breaking the fast.
When fasting you can expect to burn about 200g of fat a day, more or less depending on your metabolism and activity level. It's very likely that you're continuing to burn fat, but it doesn't show up on the scale because you're retaining more water. Feel free to experiment, but don't get discourages. If you lose 1/2 to 1 kg per week, you're doing great. You do have to keep it up though, so adjust your strategy to something you can maintain.
Based on the set-point weight effect, I set myself plateau goals. I maintain a pretty steady workout regime, and then vary the number of fasting days I do to either lose or maintain weight. So for example, this October I'll do 5 days of 21 hour fasting (and eat healthy on the weekends), expecting to lose a few hundred grams of fat each week. Then I'll try to maintain my new weight for a week or two with a number of fast days, and then I'll try the cycle again.
This is a bit of a personal philosophy, but when doing physical training, be it for strength or endurance, it's important to vary your workout, and it's important to plan recovery periods -- typical marathon training involves 3 weeks of training followed by a recovery week (where you still exercise, but less so you can recharge your batteries). Often a recover week helps you avoid or surpass a plateau. I don't see why it should be different for weight loss.
Last week I didn't lose any weight at all, but looking in the mirror and pinching my belly, and looking at the progress along my belt notches, I'm confident my body fat composition moved in the right direction. So while the scale is important, I'm not letting it be my only measure of progress.
If I'm not making my 2 kg goal per month goal that way, I'll try doing a couple 2-day fasts, or maybe another 4 or 7 day fast -- whatever is convenient.
Hopefully some of that helps you.
