Keep your fridge stocked with cut fruits and vegetables so that they are ready to eat when you are looking for a snack or food to take with you on the go.  Things that are a staple in my fridge are: boiled eggs (a dozen boiled eggs are in my fridge at all times...ready for a quick snack), baked chicken breast and fish like tilapia, plain nonfat greek yogurt, frozen berries to add to the yogurt, low fat cheese, washed and ready to use salad (romaine, arugula, radiccio etc.).
In the pantry...oats, flax meal, chia seeds, quinoa, hemp, raw nuts- favourties are walnuts and pumpkin seeds. Bran flakes (Quaker green box found in most grocery stores) can be added to anything, cereal, scrambled eggs, salads, anything.
Best find ever....Shirataki noodles...they are made of soy and have practically no calories and carbs.  Best used in soups where they can absorb the flavor of the soup and spices.  Follow instructions on the package.  They can be found in the refrigerated section of your grocery store near the tofu.
Be careful of "low fat" claims on foods...they usually add extra sugar to compensate for the lower fat and the sugar will do more damage to your waistline than the fat.
Your body needs fat to lose fat! Good fats are essential and beneficial...sugar is not.  Sugar is the only substance in our diet that is has absolutely no benefit or positive effect on our body.  It is completely unnecessary and yet it is so prevalent in our diet.  It is added to so many foods and we don't even realize it because the foods may be savory and not even sweet tasting.  You would be surprised! The next time you visit the grocery store, check the labels and if there is added sugar, think twice about buying it!!
Your sugars should be naturally occuring, in fruits and vegetables, as they also come packed with vitamins and fibre and water.  Fruit juices of any kind are also a pet peeve of mine...they lack the fibre and nutrients that you get from eating the whole fruit.  If you need to quench your thirst, have water, and then eat a whole fruit instead of drinking juice!
Just a reminder that this is my point of view and not everyone will agree....just giving you some food for thought...don't just consume foods mindlessly without questioning if it is the best fuel for your body!
Don't believe everything you read on the packages of foods at the grocery store...read the labels and educate yourself! You and your family are worth it!
