My advice to people who want to be successful into this, would be:
1. Be realistic with the calories you consume. Use an app to track everything down. Eat more raw vegetables and lean protein-source foods that are easy to account for and will fill you up (so you will not feel hungry all of the time). Measure everything to the gram. Buy a scale and try preparing most of your food yourself.
2. Don't have cheat-days. Get to your goal and then, you add a few hundred calories a day to equalize intake/expenditure (so you stop losing weight), so you will have a few hundred more calories a day to eat - now you can (hopefully) have what you want and would not be cheating.
3. Be realistic with the calories you spend. Get an armband to measure your movement throughout the day, measure yourself on the scale every week and if things don't add-up - correct for the error.
4. Don't go for more than 0.5kg loss per week. Having such a huge deficit to make 1kg of fat go away within a week can render you in a very unproductive state where you barely can get anything done during the day (that's ~1285 Kcal deficit a day, which is half of your normal calories per day if you are 30 yo male, not gaining or loosing weight and you weigh-in at 220 punds / 100kg, you would usually be expending about 2600 Kcal if you have at least some activity during the day like an hour of walking).
5. Don't listen to people's stories about weight loss and "what worked for them", if they are in their early 20's (I am 30 yo). Younger bodies (and minds) are more susceptible to magic.
If at the start of your journey you maintain some muscle through training - you will have to continue training during this period of weight loss, or that is the first thing you will lose. Even then, you have to know you will lose some muscle. I personally don't care about looks (I run and I train in Boxing) and losing some of that muscle doesn't bother me, since at the end I feel lighter, quicker and (compared to my new weight-class) stronger.
Good luck!
P.S.
- Even if you weren't training when you started and you are not trying to maintain gained muscle - doing some interval training during the weight loss will help keep your metabolic rate from falling. Your body will (partially) adjust to the weight loss by lowering your metabolism and this will solve part of the hunger, but you will feel sleepy, slow and tired and you will be burning less fat overall. Pushing yourself for just a few minutes a day with some HIIT or something similar, can offset this.
