While preparing your weekly meal plan, try to analyse the nutritional value of every meal. Although it is practically impossible to keep a check on every calorie intake, it is always recommended to keep a tab on your protein intake. Try to make sure that you are eating healthy fats and enough vitamins and minerals. Make a conscious effort to include fruits and vegetables in your meals. For your evening snacks, you can always keep something light. Snacks also generally do not require much pre-preparation so you can go with things like fresh fruits, nuts, yoghurt, hummus and vegetables, and many such things.
