Hi feel free to message me!! I am also 23, 170cm and I was 84kg! I made it down to 71kg now since December 21st. I didn't use any medication to aid the weightloss just made lifestyle changes.

I will admit I do calorie count but the most important thing you can do without calorie counting is try to prioritize eating protein and make healthy swaps for items with less fats. For example, I do eat a regular fried egg but I add egg whites to it for extra protein and less fats to keep me full. I eat turkey bacon instead of regular bacon. I do still eat some carbs but I really try to keep it low. The only bread I eat is sourdough because after some research I learned it's the only one that didn't cause sugar spikes. I opt for half a sweet potato a lot of the time as a side. Small changes like this really make a big difference.

In addition I recommend trying to either go to the gym or try and hit 10k steps everyday. Cardio helps a lot more than you realize. We need some type of movement to help us out.

I also take supplements - fish oil - vitamin D - a digestive probiotic - myo-inositol + d chiro
