The 800 calories are the product total for a Complete Routine day with a bar: two 310-calorie Shake Me meals prepared with water, plus one 180-calorie Bite Me bar. This is only part of your day. Your regular meal and any recipe additions, drinks or other food are additional.
For example, a result page displaying a total daily range of 1,450–1,750 calories would leave 650–950 calories after those three products. That remainder covers all other intake, including your regular meal; it is not automatically a separate dinner allowance plus unlimited extras. This is an explanation of the example, not a target for every customer.
On a Complete Routine day without a bar, the two shakes provide 620 calories. A Flexible Routine day with one shake and one bar provides 490 calories before its two regular meals and other intake. Follow your own plan rather than trying to make every day equal 800 calories.
