How to curb cravings?

That idea up there about analyzing the situation is spot on.

Trying to lose weight too fast will backfire eventually. Rules of thumb: Don't cut more than 20% of calories below your estimated maintenance calories, maybe 25% if severely obese. No matter the estimates, once you have 4-6 weeks (whole menstrual periods) of experience data, don't lose more than 0.5-1% of current weight per week, with a bias toward the lower end of that unless severely obese and under close medical supervision for deficiencies or complications.

Slower than those rules of thumb is fine, if it's more achievable. Sometimes a slow loss rate will get us to goal weight in less calendar time than a more extreme cut that causes deprivation-triggered over-eating, breaks in the action, or even giving up altogether.

There's no need to put any food (that you're capable of moderating) completely off limits. You'll want that food sometimes, someday, so why not try to figure out how to manage it now? (Many of us have certain foods we can't moderate, i.e., once started we'll eat the whole bag/box/thing. Those may have to be off limits at least initially, maybe cautiously re-introduced with a good plan further down the road.)
.
There aren't really "diet foods" and "healthy foods" or "good foods" and "bad foods", short of actual poisons or allergens. What mainly matters for health is the overall nutrition on average over a day or few. Most of us can fit a few higher-calorie, less nutrient-dense treats into a reasonable calorie goal, if that makes it easier to stay on the path.

Don't do extreme, punitive, ultra-intense exercise either. It's not t thhe best route to weight loss OR fitness improvement.

On the weight loss front, it can spike appetite. Also, it causes fatigue, making us drag through the rest of the day, rest more, do less, burn fewer calories doing daily life stuff, effectively wiping out some or all of the exercise calories. The sweet spot is enjoyable (or at least tolerable/practical) increases in movement that are manageably challenging to current capabilities, making us feel energized (not exhausted) for the rest of the day (after maybe a very few minutes of "whew" right after the workout).

That's the sweet spot for fitness improvement, too: That manageable challenge is what creates fitness improvement. As we get fitter, we should increase something (frequency, duration, intensity or type of exercise) to keep a manageable challenge always in the picture.

For feeling full, different things work best for different people. Some people find protein filling, some fats, some high volume low calorie foods (like big servings of low-cal veggies). Timing of eating or of particular nutrients can also make a difference. Notice days or times within a day that you feel relatively more full or relatively more hungry than usual in those circumstances. Look at your eating patterns in your diary that day (or even the day before). See if you can find patterns. Experiment. Others can give you ide as to try, but only you can find the ones that work for you in a personalized way.

Timing of eating can matter, too. Different people here do best on anything from one bigger meal a day (OMAD) to near-continuous snack-sized mini-meals spread through the day. Again, pay attention to how you feel, and experiment. You can find your best approach.

Other good advice above: Start. Then stick with it. If something you try doesn't work for you, it's not a failure. You've simply found one thing that doesn't work for YOU - useful knowledge. Try something else. Keep going. Only stopping fails. Keep. Going.

Best wishes!
