Hi I am new to this

Don't fall into diet fads.
You can still eat nice foods, some sweets/chocolate/junk foods etc while dieting. Just set aside some calories for that kinda thing a few days a week (or every day if you really 'have' to)
You need to change your lifestyle permanently if you want to stay at your target weight once you reach it. You can't just stop dieting and go back to the way you used to eat before. Obviously you'll be able to eat more each day, to maintain that weight. But you'll still have to track your calories and so on.

A high protein diet (lean meats, eggs, fish, etc) with 'healthy' fats and fiber, is good for making you feel full / not hungry for longer periods of time. So if you do find you're always hungry, try replacing some cereals/breads/potatoes/etc with extra protein or fiber. but don't do something ridiculous like trying to eat only 20-50g of carbs / day or less.

Don't set your daily calories too low either. Your body will start adapting and making it difficult to lose weight. + you'll be hungry regardless of what you eat, if your calories are too low anyway, and then when you start eating more, because of the adaptations your body made, you might gain weight for a period of time then.

There's no supplements or miracle foods or pills. Don't fall into any of that.
Caffeine + Green Tea Extract are effective at appetite suppression and slightly increased heart rate and metabolism for short periods of time. But you quickly grow a tolerance to them. So would have to stay off them for periods of time as well.

Cardio is good. Healthy and everything. But strength training / lifting weights is great for weight loss too. You wont gain any real muscles. You'll preserve alot more of the muscle / lean mass you currently have when losing weight, if you do strength training. + for the coming 24-48 hours after lifting weights, your body will burn extra calories too while repairing muscles.

Some basic common sense advice right there. Haha
