Try to get more plant-based diversity with greens such as kale, arugula, bok choy, collard, spinach, broccoli, mustard greens, kohlrabi and some more. Also, the leaves of some root vegetables like turnip, carrots, beets, radish are extremely nutrient dense and loaded with minerals, vitamins and fiber with little to no calories.
When you eat a plant-based diet that are rich in whole foods like vegetables, fruits and whole grains - you are setting yourself up for lower inflammation and better gut health. Your need for the use of supplements will also decrease. The more colourful fiber fueled foods you choose to eat, your gut microbes will reciprocate by keeping your digestion in check.
I also believe, by adding in some high quality protein and healthy fats you are able to stave off cravings and stay full longer.
