Dizziness weakness and losing weight

I'll be short. I am Mj. 33 years old. I was struggling to lose weight, and always in the middle of the day I would feel dizzy, tired, and weak, but after following your diet and finding more about body health, diabetes, the keto diet, fasting, my life changed 360°. I do more exercise now I feel more energized, stronger, less hungry. I was 78kg and today i am 63 kg. Thank you Dr.Berg
