Is this good for weight loss?

Is this keto or not? And why?

Yes, this cake is keto-friendly because it uses hazelnut flour instead of wheat flour and a sugar-free sweetener instead of sugar. The recipe keeps net carbs low through high fiber and fat content, making it suitable for maintaining ketosis when eaten in moderation.
