I got a little more overweight then I wanted to and I slimmed down my belly fat while keeping my muscles by doing the following: *first I should say I was doing my normal workouts during this nothing special added to it* -but eat a high protein breakfest (so your not craving more food then you need throughout day), only drink water (a shit ton, especially before meals) and also tea or coffee because they boost matabalism, make sure you have a lot of fiber in diet, make sure you get enough sleep (seriously, sleep is a big factor in loosing weight surprisingly), and cut back on sugar I lost 30 lbs of fat getting me back to my normal bulk weight,
Also if you want to try it I don’t know to much about it but my friends have had success with intermediate fasting, I know it sounds unhealthy but it’s actually really healthy for you and some people feel better doing that, Id do some research into that.
