This is one of the biggest differences between the two, as we’ve taken two rather different approaches here.
Calories vary between the different flavours, which you might not notice right away as on the main page, each flavour is listed to contain 200 calories. Once you click on “see full nutritional data” however, you see that’s not strictly true, as even on the “typical values” page, it’s listed as 188 calories.
We all know the numbers, but to reiterate it’s recommended that women eat at least 2,000 calories a day, with 2,500 being recommended for men. With that in mind, if you replace an entire meal with a 188-calorie shake, you may experience some difficulties with food cravings, lethargy and mood regulation.
When you’re trying to lose weight, the low-calorie option may seem more desirable, but the fact of the matter is you’ll have one of two outcomes: you’ll either lose weight far too quickly, facing numerous potential health problems as a result, or you’ll give in to the food cravings and hunger you feel, and not lose weight as a result.
Finally let’s talk about value, as these two are similarly priced on the surface, with 14 meals costing £1.93 per meal with Rootana and 12 meals costing £1.67 with Purition. If you wanted to get similar calories per meal, you’d have to double the amount of Purition, bringing its price up to £3.34 per meal.
