High‑protein bulk meal prep became popular in the United States during the early 2000s as natural bodybuilding and gym culture grew. It emphasizes affordable, nutrient‑dense foods that support muscle growth while keeping costs low, reflecting the DIY spirit of many fitness enthusiasts.

In the Midwest, bulkers often rely on beef, potatoes, and dairy; on the West Coast, chicken, quinoa, and avocado are common. The Southern style favors pork and rice, while the Northeast leans toward fish and whole‑grain breads. Casey Kelly’s plan blends these influences with universally cheap staples.

Meals are usually portioned into reusable containers for grab‑and‑go convenience. Breakfasts like overnight oats or protein‑packed French toast are eaten before training, while lunch and dinner consist of a protein, a carb (rice or potatoes), and a vegetable, often drizzled with oil or mustard for extra calories.

Bulk meal plans are most common during “cutting” or “bulking” phases of a training cycle, especially around competition prep, personal best attempts, or when athletes aim to gain lean mass for the summer. They’re also shared during fitness challenges and community “meal‑prep Sundays.”

Casey Kelly focuses on ultra‑budget ingredients from Aldi, uses whole‑food carbs like potatoes and rice, and incorporates simple sauces (mustard, hot sauce) for flavor without extra calories. The plan also emphasizes cooking efficiency, using an air fryer and batch cooking to keep prep time under an hour.

Common errors include overcooking chicken (dryness), not rinsing rice (gummy texture), overcrowding the air fryer (soggy veggies), and skipping the rest period for cooked proteins, which can lead to rubbery texture when reheated.

An air fryer circulates hot air quickly, creating a crisp exterior with less oil and in a shorter time than a conventional oven. This aligns with Casey Kelly’s goal of minimizing prep and cook time while keeping meals budget‑friendly.

Yes. Cook all proteins, rice, and vegetables in one session, then portion into airtight containers. Store in the refrigerator for up to 5 days or freeze individual portions for up to 2 months. Overnight oats should be kept sealed in the fridge and eaten within 5 days.

The chicken thighs should have a golden‑brown exterior with a slightly crisp edge, while the interior remains juicy and reaches an internal temperature of 160°F. Over‑browning indicates too high heat; under‑cooking shows a pink center.
