Conor McGregor ate six meals a day with protein shakes to gain 34 lbs in 6 months, according to his trainer

• UFC star Conor McGregor said he gained 34 pounds in the past six months.
• His muscle-building diet included six meals a day with chicken, veggies, and protein shakes.

UFC star Conor McGregor recently shared on social media that he's moved up a weight class, bulking up to 190 pounds in the past six months. Following a shocking mid-fight injury in July, McGregor has been working with trainer Alejandro Celdrán to build muscle with a strict diet and focused workouts, according to Spanish outlet AS.

The fighter has been relying on foods like chicken, fish, eggs, and protein shakes to make gains, eating six meals a day in total, Celdrán told the Spanish newspaper ABC. Here's what a typical day of muscle-fueling meals looks like for McGregor, according to his trainer.

McGregor focused on protein with every meal

To build muscle, Celdrán said McGregor needed at least 130 to 180 grams of protein per day, or about .7-1 gram per pound of body weight, according to ABC. As a result, each plate of food was comprised of about 40% protein, 30% vegetables, and the final 30% from carbohydrates.

For breakfast, McGregor would eat cereal and eggs, with a mid-morning snack of fruit, honey, and a salad, according to AS.

His main meal would often be chicken with rice and a veggie, like asparagus. For dinner, McGregor often enjoyed an Irish stew of meat and potatoes.

McGregor's meals are flavored with plenty of herbs like basil and oregano, according to AS, which are a rich source of antioxidants and may help reduce inflammation and promote cardiovascular health.

McGregor also drank shakes to round out his diet with liquid calories. He'll consume two a day, according to AS — a vanilla and peanut butter shake with his main meal, and a chocolate shake with organic tea before bed. Another favorite shake recipe is a blend of peanut butter, banana, frozen berries, and oats, according to ABC.

According to his trainer, McGregor's meals were carefully balanced with the right proportions of carbs, protein, and fats, AS reported.

All three nutrients are helpful for gaining muscle, according to experts. Protein is essential for rebuilding tissue after exercise, carbs are crucial for fueling workouts, and fats help maintain a calorie surplus, which is required for bulking up.
