The absolute best way to get rid of stubborn fat, is to clean up your diet and and do high intensity interval training at least 2x a week. It won’t be easy, but Hiit works wonders. You pick an activity and work out at 80%-90% percent maximum heart rate capacity, for a short burst, followed by a slightly longer interval, at a more relaxed pace. This type of exercise will keep your body in fat burning mode the longest.
As far as diet, start by getting rid of as much processed food as you can. Carbs are ok, as long as you stick to whole grains and whole foods, and of course, reasonable portions. Stay away from added sugars, but naturally occurring sugar from fruit is fine. Load up on fiber and veggies, and lean protein. Download the MyFitnessPal app or something similar, so you can get an idea of how many calories you should be eating in a day, and log your food for a few months. You’ll be surprised by how many calories are in things. They will also have a bunch of great meal suggestions and articles. You don’t need the paid version, either, everything you need is in the free version. Also, I find that for me, I have to have 2 cheat meals a week. And nothing is off limits all the time. Otherwise, you won’t be able to stick to it. Like if I really want a glass of wine, then I know I have to either shave those calories off of somewhere else, or put in more exercise time. This will only work to a certain extent, though. You can’t do it every day and get away with it. 80% of the time, you need to follow healthy/clean eating, or the weight will creep back.
