# Update Meal Plan Settings

Use the `updateMealPlanSettings` mutation to update or overwrite the user's meal plan settings. All the arguments to be sent are optional; however, it will update only the arguments sent in the mutation. The information is saved and it can be later requested by executing the [mealPlan](https://docs.suggestic.com/graphql/query/queries/meal-plan/meal-plan-1) query. 

### Required Arguments

|  **Name**  | **Type** |                                                                       **Description**                                                                       |
| :--------: | :------: | :---------------------------------------------------------------------------------------------------------------------------------------------------------: |
|  `update`  |  Object  |                                    Update the values added to it. For example, `update: { calories: 1600, protein: 20 }`                                    |
| `ovewrite` |  Object  | Overwrite only the values added to it. The ones that were not added will be set as `null`. For example: `overwrite: { format: [BREAKFAST, LUNCH, DINNER] }` |

{% hint style="info" %}
If the `update` and `overwrite` arguments are defined at the same time, the `overwrite` argument will be the one applied. 
{% endhint %}

### Available Arguments

Use the following arguments within the update and overwrite objects:

<table data-header-hidden><thead><tr><th width="184.33333333333331">Arguments</th><th width="150">Type</th><th>Description</th></tr></thead><tbody><tr><td><strong>Arguments</strong></td><td><strong>Type</strong></td><td><strong>Description</strong></td></tr><tr><td><code>calories</code></td><td>Int</td><td>Total Calories per day. If using the overwrite and no calories value is defined, the default value is set to 1400.</td></tr><tr><td><code>carbs</code></td><td>Int</td><td>Percent of Carbs</td></tr><tr><td><p></p><p><code>fat</code></p></td><td>Int</td><td>Percent of Fat</td></tr><tr><td><code>format</code></td><td>MealTime!</td><td><p>Requested meals per day format. Available options: <code>BREAKFAST, SNACK, LUNCH, DINNER</code>.  </p><p>The list cannot have a null value, i.e, <code>[BREAKFAST, null]</code>. However, it is possible to send the list in the following formats:</p><ul><li><code>format: null</code> </li><li><code>format: []</code> </li><li>Not send a format</li></ul><p>If not format is sent, the following format is set as default: <code>[BREAKFAST, SNACK, LUNCH, DINNER]</code></p></td></tr><tr><td><code>omega3</code></td><td>Float</td><td>Percent of Omega 3.</td></tr><tr><td><code>protein</code></td><td>Int</td><td>Percent of Protein</td></tr></tbody></table>

### Example

The following example updates the protein and calories values:

{% tabs %}
{% tab title="Mutation" %}

```graphql
mutation updateMealPlanSettings {
  updateMealPlanSettings(
    update: { calories: 1600, protein: 20 }
  ) {
    success
    message
  }
}

```

{% endtab %}

{% tab title="Response" %}

```graphql
{
  "data": {
    "updateMealPlanSettings": {
      "success": true,
      "message": "Settings updated"
    }
  }
}
```

{% endtab %}
{% endtabs %}

The following example updates the meal format and sets automatically the rest of arguments not send as null:

{% tabs %}
{% tab title="Mutation" %}

```graphql
mutation updateMealPlanSettings {
  updateMealPlanSettings(
    overwrite: { format: [BREAKFAST, LUNCH, DINNER] }
  ) {
    success
    message
  }
}

```

{% endtab %}

{% tab title="Response" %}

```graphql
{
  "data": {
    "updateMealPlanSettings": {
      "success": true,
      "message": "Settings updated"
    }
  }
}
```

{% endtab %}
{% endtabs %}

The following example uses query variables and updates the calories and proteins values:

{% tabs %}
{% tab title="Mutation" %}

```graphql
mutation($update: UpdateMPSettingsInput, $overwrite: UpdateMPSettingsInput) {
  updateMealPlanSettings(update: $update, overwrite: $overwrite) {
    success
    message
  }
}
```

{% endtab %}

{% tab title="Response" %}

```graphql
{
  "data": {
    "updateMealPlanSettings": {
      "success": true,
      "message": "Settings updated"
    }
  }
}
```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="QUERY VARIABLES" %}

```graphql
{
  "overwrite": {"calories": 1600, "protein": 20}
}

```

{% endtab %}
{% endtabs %}
