Consider having a bowl of real oatmeal, not instant, especially for your breakfast. You will not only find it delicious and fulfilling, but also, it will help in reducing cholesterol level in your body. It helps you in staying fuller as it is high on fibre index and low on glycemic.
Consider having an apple as a morning snack. Apples are packed with fibre and since you have to chew them longer, this also helps your brain register that you are full.
Taking salad at lunch time is also a great idea to suppress your appetite. Again, salads are crunchy and full of fibre, so they must be chewed longer, sending those, "I'm full!" signals to your brain.
Keep the dressing on the light side or omit it all together. A little trick you can use is to have the dressing on the side and dip your fork into the dressing before putting salad on it. You still the get the taste of the dressing, with much less calories.
Have a bottle of water with lunch and throughout the day to keep hunger at bay. Try a twist of lemon in your water; the sour taste of lemon helps to suppress your appetite naturally, as well.
For an afternoon snack, try Flax Seeds or Pine Nuts, or a trail mix which includes both. Pine nuts contain pinolenic acid, a naturally occurring polyunsaturated fat that stimulates two powerful hunger suppressing hormones. Both hormones play a major role in signalling to the brain that you're no longer hungry. Flax Seeds are rich in Omega-3 fats and fibre.
Craving chocolate? Try some high quality, organic dark chocolate. It is rich in antioxidants and that bittersweet taste helps to curb hunger. Less is best -remember, everything should be consumed in moderation.
Finally, before going to bed, try a cup of Green Chamomile Tea to lull you and your appetite to sleep. Green tea is another appetite suppressing ingredient, which is thought to naturally help boost your immune system and mental alertness, while Chamomile helps your body rest and get ready for a good night's sleep.
