FAQs

What makes a protein powder keto‑friendly?

A keto‑friendly protein powder is low in carbs and sugar, uses high‑quality fats like MCT oil and contains no fillers that could kick you out of ketosis.

Can I take whey protein on a keto diet?

Yes — whey isolate or hydrolysed whey can fit into a keto diet. Just check that it’s free from added sugars and carbs.

When should I drink keto protein shakes?

Most people enjoy a keto shake post‑workout for recovery or as a meal replacement. Adjust timing based on your daily macros and activity level.

Do I need MCT oil in my protein powder?

MCT oil can help boost ketone production and energy, but it isn’t mandatory. Many keto powders include MCT for added benefits.
