Everyone has different calorie requirements depending on their shape, genes, daily activity, age and gender. The important thing to remember is that you are creating a calorie deficit in order to facilitate weight loss, the greater the deficit the more weight you will lose. But is it important to ensure you are getting the macro and micronutrients your body needs.
Our general guideline is to snack on fruits and vegetables when you feel hungry between meals. Non-starchy vegetables (this does not include peas, corn, sweet potato and butternut squash) are unlimited and fruits should be limited to 3 a day. Very low calorie meals like thin soups are allowed if you feel the need (recipes and ideas for other low calorie meals can be found here ).
