**Monitoring:** Throughout the implementation of the meal plan, continuous monitoring will be done to ensure that the calorie target is being met consistently whilst maintaining a well-balanced diet. Regular feedback will be requested for possible modifications and improvements to better suit your preferences and dietary needs. 

**EXAMPLE MEAL:**

**'Breakfast'**
* 1 medium Banana (105 calories)
* 1 medium Apple (72 calories)
* 1 Mango (201 calories)
* 1 Orange (62 calories)
* 10 grams of Cashews (56 calories)
* 5 grams of Peanuts (29 calories)
* 1 teaspoon of Flax Seeds (37 calories)

**Total 'Breakfast' Calorie Count:** 562 Calories

In this case, the Breakfast meal slightly exceeds the desired 500 calories. To fine-tune this meal to better fit the 500-calorie goal, adjustments could be made such as reducing the portion size of Mango from 1 to a half. 

**Adjusted 'Breakfast'** 
* 1 medium Banana (105 calories)
* 1 medium Apple (72 calories)
* 0.5 Mango (100 calories)
* 1 Orange (62 calories)
* 10 grams of Cashews (56 calories)
* 5 grams of Peanuts (29 calories)
* 1 teaspoon of Flax Seeds (37 calories)

**Total 'Breakfast' Calorie Count:** 461 Calories 

Now, to ensure that we meet the desired calorie count, we could increase the portion of Cashews to 15 grams, creating an additional 12 calories. 

**Final 'Breakfast'**
* 1 medium Banana (105 calories)
* 1 medium Apple (72 calories)
* 0.5 Mango (100 calories)
* 1 Orange (62 calories)
* 15 grams of Cashews (81 calories)
* 5 grams of Peanuts (29 calories)
* 1 teaspoon of Flax Seeds (37 calories)

**Total 'Breakfast' Calorie Count:** 486 total calories.  Balance this out with a glass of water and some tea (optional), and your breakfast menu is ready.
