48 years old, fit, recently removed sugar and grains from my diet; increased fat and protein, had cholesterol tested after 7 weeks. Trigycerides usually 60-70 and HDL usually 85-95. LDL around 80. Trigycerides dropped to 45 and HDL shot up to 124. Doctor is concerned that HDL could be because of neurotoxin and is concerned with the very low triglyceride levels as well as the overall total of 224. Should I be concerned and what could have caused this? Am otherwise healthy.
