I lost almost 60lbs in the past eight months and have gained some muscle as well. My goals are a standard fit gym bro look, lol.
Just to preface, everyone's bodies, habits, lifestyles are different so what worked for me, might not work for you but I found the following helpful:
Calculate how many calories your body needs to maintain, lose, or gain weight first. There are many online calculators that can give you a rough idea. That's your starting point.
Be okay eating the same food everyday, it makes the process smoother and you're less likely to fall off the wagon.
Meal prep (related to the one above). You'll have less decision fatigue. Choose meals that are easy to prepare.
Input your calories into MyFitnessPal or some sort of calorie tracking app. You need to know how much you're eating in order to lose the weight.
Be okay with being hungry. This will be tough, especially in the beginning.
Gym x 3 to 4 times a week. You don't need to lift too heavy if you're looking for a more feminine look, but doing some lifting will tone your body up as the fat drops off. There are plenty of online programs you can follow. You don't need to spend hours in the gym, usually 45 minute session will do.
If you're going to have a "cheat" meal, make it one with friends or family and limit it to only ONE meal (not day) per week.
You will see results if you're consistent with it, but you have to track and continue to do this and to maintain this. This is a lifestyle change.
