Protein shake (whey)

Whey protein isolate is low-carb (1-2g per scoop), but many commercial shakes contain added sugars and carbs (5-15g). Quality matters significantly; pure isolate is keto-friendly.

iSome keto practitioners prefer whole food protein sources and view protein shakes as unnecessary processed foods, while others accept isolate-based shakes as convenient macro tools.

Whey protein is derived from dairy, which is excluded in strict paleo. However, whey isolate is highly processed and some paleo practitioners accept it as a supplement for convenience. Whole-food protein sources are preferred.

iSisson permits whey protein as a practical supplement; Cordain and strict paleo exclude all dairy including whey. Some accept whey isolate but not concentrate.

Whey protein is processed and not traditional to Mediterranean diet. Whole food protein sources (fish, legumes, nuts) are preferred, though whey can supplement when needed.

iModern Mediterranean diet practitioners may use whey protein for convenience and athletic performance, particularly in active populations where whole food protein timing is impractical.

Whey protein is animal-derived (milk byproduct) but heavily processed and often contains additives, sweeteners, or plant-based ingredients. Many carnivores use it, but strict practitioners prefer whole food sources like eggs and meat.

iStrict Lion Diet and purist carnivores (Saladino's early protocols) avoid processed protein powders, preferring whole animal foods. Baker and others accept quality whey isolates with minimal additives.

Whey protein is lean protein source aligned with DASH, but commercial shakes often contain added sugars (5-20g), sodium (200-400mg), and artificial ingredients. Acceptable if low-sugar, low-sodium versions chosen; homemade shakes with unsweetened whey are preferable.

Whey protein isolate is lean and fast-absorbing, but most commercial shakes contain added sugars or artificial sweeteners. A plain whey isolate shake (20-25g protein, <2g carbs) requires carb and fat additions to achieve 40/30/30 ratio. Useful building block but not standalone.

Whey protein is a complete protein with some anti-inflammatory amino acids (leucine, cysteine for glutathione). However, many commercial shakes contain added sugars, artificial sweeteners, and inflammatory seed oils. Quality and formulation are critical.

iSome functional medicine practitioners view whey as pro-inflammatory due to lactose and processing; others note high-quality isolates are acceptable. Dr. Weil generally prefers plant-based proteins.
