1. Realize how gross it is
It's processed through animal bones to produce that desirable, bleach-white color.
"When it gets harvested from the cane, sugar is brown. Since brown food is aesthetically less pleasing, it is often turned white. Some companies bleach the bones of cows and then burn them into “bone char”, which is added to brown cane sugar to make it white. Usually, sugar companies don’t list whether they use bone char or less disgusting methods." -Distractify
2. Accept what it does to your body
Not only is sugar fattening, it tricks you into thinking that you're hungrier than you actually are.
"Eating too much added sugar allows the fructose found in sugar and high-fructose corn syrup to send your hunger hormones into a tailspin. The hormonal messages that tell your brain you're full aren't properly triggered, tricking your system into thinking you haven't eaten, Dr. Lustig explains." -Rodalenews
3. Understand how easy it is to drink black coffee
Aside from the health benefits, black coffee is just better.
After just a couple of weeks, your taste buds change completely. Drinking coffee black is the only way to detect the natural notes in different coffee varietals.
If you need to ween off sugar:
Always taste your coffee before adding sugar. Taste the coffee after you add small increments at a time. Doing this will automatically decrease the amount of sugar you add.
Experiment with your brewing ratio and save your results. Blindly scooping is doing you no favors.
Good luck — you've got this.
