There is no point in counting calories. They are not equal. Its truly the type that you eat and not how many.
I'm 5'2'' and easily maintain 105 with over 2000 calories a day, just light walking everyday + pilates/barre three times a week (weight loss/maintenance are 80% determined by diet, 10% genetics, cardio is overrated and will not help you lose weight, toning is most important after diet). If I begin to gain its not because of extra calories, its because I'm eating too much fruit and starches. As soon as I reduce them the few pounds come off in a few days.
Go on a primal diet. You won't have to count calories or feel deprived. You don't feel like you're dieting at all. This works for me when nothing else has. You can learn about it for free on marks daily apples free article how to succeed with the primal blueprint and find recipes on google for free
You don't even have to do a ketogenic diet if you are patient. You can do 50-100 carbs a day without counting calories, doing a ton of stressful cardio and still lose about 2 lbs a week if you need to lose. If you're maintaining, you can go to 100-150, maybe even more if you are very active. You don't even have to eat 100% primally, you can have smart indulgences and treats. I still eat some things that aren't primal but don't make me gain like beans or their products (like explore asian pastas and cappellos), full fat dairy products, peanuts/peanut butter, stevia/erythritol sweeteners, low carb desserts etc... Just eat smart foods and smart exceptions when you are hungry and finish when you feel satisfied.
My calories the other day came out to about 2230 calories, 151 carbs/93 net carbs, 134 grams fat, 121 protein. I typically eat like this and no weight gain! If I just reduced the carbs more, nothing else, even increasing calories from fat, I could begin to lose if I wanted.
Calorie king and other apps tell me that i need 1100-1300 to lose, 1550 to 1750 to maintain and 2050 to 2250 to gain for my weight, height, age, level of activity. Well that might be a good estimate if I deprived myself with an unnatural, unsatisfying, low fat, grain filled, empty carb diet that ignorant bimbos, cultist vegans, and the government still promotes due to ignorance and corporate influence, but its not so in this kind of lifestyle that humans evolved to thrive in.
Eat low fat, high carb and calorie count only if you wish to feel deprived and stay on yo-yo diets for life. Its unnatural and miserable. I'm so glad I'm not a slave to calorie counting and empty carbs anymore. Learn to eat well and you will always feel satiated, feel like you eat a decadent diet but will thrive and have slim build.
