Please, please, please - don't focus on caloric deficits. You are trying to optimize body composition for long term, not just a one day competition. You need a solution that you can sustain long term.

The key to reducing stored body fat is to reduce your overall insulin burden. [Paper] The Carbohydrate-Insulin Model of Obesity - Beyond “Calories In, Calories Out” - 2018

Fat burning, requires the absence of insulin in the blood. People using CICO for weight control are entering a low insulin state between meals, when they sleep, etc. Any time carbohydrates are consumed, blood glucose rises, raising insulin - when insulin is elevated the body will not mobilize fat from adipose tissue, i.e. it pauses fat burning. So someone eating the standard 3 meals and 3 snacks with carbs is pausing their fat burning 6 times per day (for 2-4 hours per eating session depending on their inherit insulin resistance) - Which is almost the entire day.

As a thought experiment map out each time you eat carbohydrates on a calendar, and block out 2 hours. (the nuts, the ranch, the protein supplement, fruits, beans), see how much time per day you have left over to mobilize fat.

It's really helpful to wear a CGM for two weeks, and track your blood glucose in real time, every time its not a flat line you know you can't burn stored fat.

I find the science and literature from the ketogenic metabolism very compelling: In this model you should eat as much fat and protein as your hungry for, don't restrict yourself at all - just don't mix it with carbohydrates (that increase insulin, that pause fat mobilization). It will break your plateau.

If you're doing a recomposition (burn fat and build muscle) then yeah, you are losing fat but gaining muscle so the scale can be misleading. Body fat % or pant size become better indicators. You may see what is referred to as a "whoosh" where every few weeks you seem to drop a few Kg over night (water weight).

When I am doing a recomp I tend to do weigh-ins every 2-4 weeks. When cutting I'll do it weekly.

I'm sure that I'm in a caloric deficit. Eating more raw fruits and fibrous food like beans, more fish and less meat and fats.

Have you done any tracking? It is a pain to do all the time but worth maybe doing it for a week just to be sure. I struggle with knowing when I am full and can easily put myself over on something high calorie like nuts.

If no progress for a few months, lab testing may be worth it. Thyroid issues can impact weight gain and loss.

Finally there are medications like GLP-1 (expensive in some areas) that mess with insulin production and the hunger signals in your brain that have been known to be effective.
