1) Avocado - very high in saturated fats and a great blood sugar stabilizer. It will fill you up so that you won't be looking for snacks to nibble. In a week or two, you will notice a flatter stomach.
2) Wild caught salmon - high in Omega 3s and a great addition to any salads.
3) Broccoli - well-known for its anti-cancer and anti-toxic properties. Whether you sauteed or eat them raw, they will help eliminate excess toxins e.g. estrogen from your system.
4) Raw nuts - always keep a handful of them with you. When you feel like snacking, pull them out and eat a handful of nuts. They are high in protein and they keep you full and satisfied, hence relieving you from your energy slump.
