Talk to Dietitian/Nutritionist on Losing Weight

For the last three months I lost 9kg weight from 62 to 53 kg. For the couple of months I had very disturbed sleep order. My LDL was 174 therefore avoided eating meat. Hba1c was 5.9 so stopped eating sweet and even reduced fruit intake. Skipped lunch sometimes Taking medicine for stress, prostrate and lower back pain. Recently did some diagnostic lab tests LDL dropped to 143 and Hba1c is 5.7 chest xray also clear. Is there any factors of weight loss?
