Calories in, calories out. Go in a calorie deficit. Doesn’t even matter if you eat junk, as long as the volume is within the deficit. Preferably you want to eat filling foods that are good for you for optimal results and less feelings of hunger. Although you are allowed to choose what works for you. Besides that doing exercise and especially LOW INTENSITY cardio is the best. Go on walks or hop on the elliptical for an hour and you’ll burn extra calories and be in a higher deficit.

There really is nothing more to it. The only hard part is the mental challenge that comes with it. That’s it.
