Cal consumption to loose 20 lbs
Just like what anthony said , what is ur calorie intake every day? If it's high then start decreasing it gradually to reach 1200 or 1100 same if it's low just increase it gradually . But from my perspective I think If u want to loose weight count how much u have burnt every day burn from 500-1000 calories every day and do not worry on how many calories u had eaten but make sure it's enough to build some muscle cause the more muscle u have the higher ur metabolism is
Use the myfitnesspal app to find your daily caloric requirement and track your calories to know when you're below or getting close or over.
All the calculations are based on 3500 calorie per pound which is not correct because nobody loses pure 100% fat, but it's a good place to make a plan you can follow that WILL show results.
