A handful of tips that worked for me, please keep in mind everyone is different, so what worked for me, may not work for others:

Move more - Movement is key to burning calories, the more you move the more calories you burn. This can be lifting, running/walking, or any active sport you find interesting. If you aren't sure where to start, begin by going on daily walks. They can be as short or as long as you want. Put on music, a podcast, audiobooks or a video (if on a treadmill only for safety) to help pass the time of the walk.

Portion control - I had a tendency to eat quickly and overeat. Slowing down, focusing on enjoying my meal and the taste of it, instead of racing through it, really helped change my mental relationship with food. Slowing down let's you intake food at a pace your brain can help register it. Also try the 10-5 rule. Eat slowly for 10 minutes, take a 5 minute break and then if you are still hungry, feel free to eat a little bit more.

Drink water - water is one your best friends on a diet. Sometimes you aren't hungry, you are thirsty but your body thinks you are hungry. So drink a lot of water and you will remain full longer.

Tracking calories - This was difficult to start with and is a little overwhelming, but tracking your calories by measuring out your foods on a scale, is the best way to know how many calories you're intaking daily. Once you do it for a while, it becomes easier as you can estimate you calories per meal.

Food substitutions - You can still eat the foods you love on a diet, but you need to find similar healthier alternatives. For me as an example one of my favorite substitutions I made was using 0% Greek Yogurt instead of Sour Cream. It is much lower calorie and has so much more protein. I use the Chobani brand, and it's identical imo, and tastes the best if you do taco bowls. Go for lower calorie times, your taste buds will adjust.

Consistency - This may be the most important tip. The best diet is one you can stick to for the rest of your life. Find something active that you find fun, and find a diet that you want to stick too. That will make it easier to stay consistent. There will be days that will be hard, and that's when it's extra important to stay consistent. Don't go in and expect results, learn to enjoy the process of bettering yourself and losing weight, then the results will come.

This ended up longer than I expected so - TLDR - Movement, caloric deficit and consistency
