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.
