Not all calories are equal, all carbohydrates are not equal. Choosing the correct source of carbohydrates is going to give you more nutrition, balance your bloodsugar and reduce risk of cardiovascular diseases.
When you eat simple carbohydrates like a mcdonalds hamburger, they don't contain any fibers to slow down the rise of bloodsugar and they don't contain alot of nutrients, it's mostly empty calories. After eating the hamburger, your blood sugar will spike. And when the blood sugar rises, the body releases insulin which will place the sugar in your body cells, and then your bloodsugar will crash.
And a few hours later you're starving, tired and hungry.
To avoid that bloodsugar crash, you have to consume complex carbs that have fiber, good nutrients (an ideal balance of carbs, protein, fat, vitamins, minerals and water) which will give your bloodsugar a slow increase of instead of a spike, and then slowly go back to normal level of bloodsugar, instead of a crash.
Every time you eat simple carbohydrates (like the hamburger in your picture), the effect of the insulin receptor in the cells will slowly stop registrating the presence of the insulin, and the insulin is not as effictive as it would have been, have you had consumed a more advanced type carbs.
When you are insulin resistant, it's not that your pancreas stop producing insulin, its just that the insulin receptors in the cells have stopped being effective and they stop working gradually.
You can slow down this process by not eating bad carbohydrates. If you overeat (all bodies have a different tolerance level of how long your body cells can constantly work with high insulin levels, until they stop noticing the insulin. But asian people are more prone to becoming insulin resistant than any other ethnicity, especially south asians because they usually have less muscle and more abdominal fat, thus increasing the risk of insulin resistance, even at lower BMIs.) on simple carbohydrates.
