Absolutely agree that calorie deficit is required to start burning fat, which is what is required here.
For some people, switching between burning fat and burning is easy, something the body does without any problem. They are lucky and can genuinely reduce their calories a bid and over time will loose weight.
However, if your body is not so good at switching, and you eat a significant amount of carbs which ultimately turn into sugar, your experience of eating fewer calories than required to maintain your current weight, will involve feeling tremendous hunger as your brain fights your desire to loose weight.
If you find you experience that tremendous hunger, I encourage you to try eating low carb. Without the insulin which your body releases to burn sugar, you start to burn fat to keep your blood sugar stable and no massive hunger drives you to break your diet.
if you have a lot of weight to loose, you can eat low carb to your hunger and , after a few days of converting to burning fat, loose weight in a way that feels effortless. Best to get some help with what low carb means in this context, it is a very unforgiving way of eating. Any cheat will knock you back to burning sugar so get some support.
at some point, which I have now reached, I need to look out at the calorie value to reduce my portion size and get rid of the last few pounds.
Hope you find what works for you.
