After photos of a newly “thicc” McAvoy went viral, and the story of how he got jacked spread all over the Internet, McAvoy had to clear up that he may have exaggerated his calorie intake just a smidge. Earlier this week, the actor posted a screenshot of a Men’s Fitness article claiming that he was eating 6,000 calories a day for his new movie, Glass, along with the following caption:ae0fcc31ae342fd3a1346ebb1f342fcb It’s really sweet of McAvoy to be concerned for other peoples’ health and safety, and he’s totally right, as counting calories is rarely the best way to get fit. To prepare for Glass, the M Night Shyamalan follow-up to Split, McAvoy trained with Swedish celebrity coach Magnus Lygdback, who has worked with Alicia Vikander on Tomb Raider, Ben Affleck on Justice League, and Alexander Skarsgard on Tarzan, among many others. On his official website, Magnust states that the philosophy at the center of his method is “embracing the ’ethos of an athlete’—approaching life fitness with the same specific intensity and structure that an athlete would, whilst also maintaining a balanced and healthy life.” Since Magnus applies “individually tailored psychological tasks, much in the same way that a sports psychologist would for a professional athlete,” the program for each of his clients is very unique and might not be ideal for you. But if you, like McAvoy, do want to try the Macro diet, you should know that it involves counting your meals’ macronutrients—aka the amount of carbs, protein, and fat you consume—as opposed to just calories. The idea is that the system would help you make much healthier eating choices. For example, both a 4 oz serving of salmon and a snickers bar are about 250 calories, whereas one is high in carbs and fat and low in protein, the other is likely to give you the protein kick you need to turn fat into big, beautiful muscles. Of course, the Magnus Method is also very heavy into exercise (he had Vikander do heavy lifting five to six days a week, climbing two or three times a week, and boxing and MMA four times a week on top of daily stunt rehearsals for Tomb Raider), so there’s no avoiding that. If you need some inspiration, here’s McAvoy himself goofing around with Magnus at the gym.
