It's my second week on the diet and I'm not losing weight lol

These days, I've been trying hard to stick to a low-carb, high-fat diet, right? I drink bulletproof coffee for breakfast and eat protein-based lunch and dinner, but my weight isn't decreasing as much as I thought, so I'm losing motivation a bit~~ Does it really happen that quickly? My body feels a little better, but I wonder if it's just my mood. I was so hungry today that I grilled pork belly, but I feel bad about myself. Still, I'm not going to give up here and will try hard again tomorrow! Good luck with your diet, everyone!!
