Does PHD Diet Whey Have a Lot Of Syns?

If your looking to lift weights or up your protein intake in general then it might be worth including some protein powder in your diet, but these powders can often be quite high in calories, especially if mixed with milk.

PhD diet weigh has 4.5 syns per serving, which can become quite high once mixed with milk, this means you should stick to one protein shake a day on the slimming world plan and ensure you have enough syns free. 

In our guide below we will go over how to make protein powder lower in syns, other PhD protein powder syns and some lower syn alternatives from other brands. We've also included a slimming world friendly protein ball recipe for you to try if you are looking to up your protein intake.

Why Is Protein Powder High In Syns?

You might be a little shocked to learn that diet whey has nearly 5 in syns, but this is due to the high protein content from the whey which comes from dried milk. Some protein powders also have added sugar and fillers which contributes to the high-calorie content.

One way to reduce the syns of a PhD diet whey shake is by making it with non-dairy milk or just plain water as mixing with semi-skimmed or full fat could add another two or three syns using up nearly half of your daily syn allowance unless you use the milk as your healthy extra A.

If you find protein powders too high in syns then you can try to adjust your diet so as your add in more natural protein sources from food such as lean chicken and fish which can be syn free on the SW plan.
