Try a Mediterranean diet. You need something long term. I don't like the term diet, as it usually conjures up images of crash diets. I prefer lifestyle.

Try not to eat any processed foods.

Whatever diet allows you to consume less calories as easily as possible. There's no way to predict what diet will work best for you, it's just trial and error.

Go walking or swimming

Eat less, move more. There’s no magic involved in weight loss.

diets dont work overall. A lifestyle change is what should be more applied. Eat food you enjoy but smaller portions at breakfast, lunch and dinner. No snack foods though except for maybe a bit of fruit and always drink plenty of water. Get the sugary crap out of your life.
Exercise daily at least for a hour. Even something simple as walking.

Pick a time of 6 or 8 hours that you only eat then.

Eat less and healthy, cut down fast food and sweet beverages, sweets as much as possible, do workout (imo best is running and swimming) and get good sleep. No need to follow some fancy, unrealistic, diet plans almost none of them actually work. You are almost certainly gonna relapse and after that you are gonna gain more weight as a result.

It's about balance. Eat less, eat healthy and exercise more. Make all of that your dairy routine and you should see some benefits.

Keto

Instead of soda have diet soda

Stop all sodas and sugar

Don’t diet diets don’t work you end up Gaining it back or more than you were just eat smaller portions rather than cut out

Truth is eat less. I don't mean to advocate unhealthy diets. But I only eat once a day. And I did that the whole year. I was 140 2 years ago. Then went down to 125. And then 118 rn. But now I feel unhealthy so I'm eating more again. I think it's because I'm eating more sandwiches because I work at one. But I'll only eat lettuce wraps. No bread. Cut that out and dairy.
