A 90-calorie protein shake sounds great - until you're hungry again 30 minutes later…
If you've compared Protein & Fibre to other protein powders, you might have noticed the calorie count is higher. Around 174 kcal per serving, compared to 90–150 kcal from most whey and vegan protein isolates.
On paper, that looks like a disadvantage. In practice, it's the opposite.
Empty Calories vs Working Calories
A 90-calorie protein isolate gives you one thing: protein. The fibre has been stripped out. The fats have been removed. The naturally occurring nutrients are gone. What's left is a single macronutrient in powder form, sweetened with stevia or sucralose to make it drinkable.
It does one job. And then it's done. Your body processes it quickly, there's nothing to slow digestion, and 30 minutes later you're hungry again.
Protein & Fibre is different. Those 174 calories include 21–23g of protein, 8–-0g of fibre, healthy fats, and naturally occurring vitamins and minerals - all from whole food. The fibre slows digestion. The fats provide sustained energy. The protein supports recovery. Everything works together, the way food is supposed to.
The result? You stay full. For hours. Not for minutes.
The Calorie Maths Nobody Does
Here's the thing about low-calorie protein shakes: they don't exist in isolation. Nobody drinks a 90-calorie shake and then eats nothing for the next four hours. They drink the shake, feel hungry an hour later, and reach for a snack - a banana, a handful of nuts, a biscuit, a coffee with milk.
That 90-calorie shake just became a 300-calorie event. And the snack probably wasn't as nutritious as what you'd have got from a single serving of Protein & Fibre in the first place.
174 kcal that keeps you going until your next meal is fewer total calories than 90 kcal plus whatever you eat because it didn't.
After Exercise, Your Body Wants Real Fuel
If you're using protein after a workout, the case is even clearer. Your muscles have burned through glycogen. Your body needs to recover. Sports nutritionists don't recommend isolated protein on its own after training - they recommend protein alongside carbohydrates and nutrients to replenish energy stores and support full recovery.
A 90-calorie isolate gives you protein and nothing else. Protein & Fibre gives you protein alongside natural carbohydrates from ground dates, fibre for digestion, and healthy fats for sustained energy. It's closer to what your body actually needs after exercise - without having to eat a separate meal on top.
Perspective
174 kcal is less than a banana and a yoghurt. Less than a latte. Less than virtually any protein bar on the market. It's a modest amount of energy from real, whole-food ingredients that your body knows exactly what to do with.
The question isn't why does Protein & Fibre have more calories. The question is why does your current protein have so few - and what did they take out to get there.
