One of the questions I have: are you currently taking any medications? Some can stall weight loss, so this could be contributing to the situation as well. Be careful here, and I am not a medical professional, but the ratio of your triglycerides to HDL is now considered the most important health marker for metabolic and cardiovascular health. Remember, after 3 months your metabolism is still adapting and your Cholesterol and LDL numbers are not necessarily the best indicators, as a metabolism transitioning to fat burning can exhibit higher lipid numbers in a blood draw in the beginning.

The fact that you feel good and your clothes are fitting better are good signs. Also, as madeyna says, you may want to post what you eat during a normal week, as sometimes things consumed can impact progress. In addition, it's not essential to do IF early on either as long as you manage your carb consumption and eliminate processed foods, including any type of low carb dietary garbage like Atkins or Quest bars.
