I started right away at as low carb as I could possibly go. Then I went even lower. I didn't see any results for 6 weeks even though I ran, power-walked or hiked every day. Even though I ate only two meals a day and normal portions and no snacks. Even though I didn't cheat not even one single tiny little bit. Even though I ate no fruit at all. 6 weeks and nothing! Argh!
But, in the mean time, I had TONS of other results. I had low carb flu, felt weak. I had terrible electrolyte issues to figure out. I started taking supplements to deal with that. I felt different, mentally more calm, physically very calm from the lack of hunger and energy spikes. I've had cramps. I've had a few days when I though maybe I was killing myself with this diet, like seriously maybe I'm going to die. I've had days of feeling really awesome. I've gotten my strength back. I've accidentally intermittently fasted without hunger even though I was hiking in the mountains. And now, finally, at long last, real weight loss. It's finally working.
You may have to go lower carb or give it more time or both. In the mean time, it might help a little to pay attention to other changes in your body. Is anything different happening at all yet?
