Think paleo, limit fruit and grains and eat lots of fresh veggies and lean protein with healthy fats (avocados, coconut oil, almond butter). The protein and good fats will give you energy and help you feel satiated longer. Limit the amount of processed foods to zero. This means shop on the exterior edges of the grocery store and avoid the middle aisles. Even packaged foods claiming to be healthy contain loads of sugar and sodium, making it impossible to shed those unwanted pounds. Remember, weight loss is all about calories in vs. calories out, so make sure the ones you are consuming will nourish your body and give you energy.
