If you're cutting
Ditch the rice Krispy bars and the cooking oils use 1 cal spray
Replace those cals with quality carbs in meal 4
And some avocado or almond butter in your last meal
Ideally swap your isolate in last meal to casein, cottage cheese or fat free Greek yoghurt
Then if weight loss stops these are areas you can look at dropping cals
Agree with everything said here. Learn to like protein bars if you really have a sweet tooth and check the macros some protein bars are basically candy bars with protein.
Quest Kirkland to name a few are good ones.
Also on the fats it's fine to eat low fat just don't eat 0 fat you should still try to get healthy fats in diet.
I do my "starving" and fat burning when I sleep has always worked fine for me. Why suffer awake when you can do it asleep? Smash some water before bed too and as pooley said casein or cottage cheese slow digesting proteins.
