Unfortunately, we can't pick and choose where our bodies take fat off. The only way to lose the fat around your abdomen is to lose weight/fat overall. In most cases, the stomach area is the first place most people store fat, and the last place fat is lost.
To achieve weight loss, you'll need to be in a calorie deficit. Pair regular exercise with a healthy diet. Make sure to include enough protein to keep your muscle mass up, but also don't forget to eat fruits and vegetables, whole grains, and low fat/fat free dairy or dairy alternatives.
Healthy protein options beside your personalized protein powder include seafood, eggs or egg whites, lean meats like chicken and turkey, tofu, beans and lentils. Most fruits and veggies are great, but watch out for the higher calorie content of dried or juiced produce. Whole grains are foods like popcorn, brown rice, whole wheat pasta and bread, whole grain crackers, oats, etc. Dairy products are pretty simple with milk, cheese, yogurt, and cottage cheese. Eat a variety of these food groups, and we would also suggest trying to do small and frequent meals/snacks throughout the day. Eating small portions 4-6 times per day can really help control your hunger and leave you feeling energized.
Portion sizes are a huge part of your weight loss. Even if your diet is well-balanced, you can still be eating too many calories. In general, you can eat the healthy, nutrient dense foods listed above more freely, but gorging yourself on even the healthiest foods is counterproductive. Although foods like peanut butter, nuts and seeds, plant oils, and avocados are healthy, they still have high calorie and fat content. Definitely include them, but be mindful of serving size. If you ever measure out a serving of peanut butter, you'd probably be shocked by how small it is for 190 calories.
