Nutritionist Critiques Mark Wahlberg’s Diet and Fat Loss Routine
Morning Rituals
Wahlberg starts his day with a zinc tablet, a triple espresso, and a cold plunge. According to DeLauer, “The zinc thing is kind of interesting. Zinc is huge, but I don’t know if having zinc first thing in the morning is doing anything in particular.”
He appreciates the espresso choice, noting that recent studies have debunked the myth that one should wait before having caffeine in the morning. “Caffeine is going to stop spiking cortisol after consuming it for a few days anyway,” DeLauer explains.
The cold plunge is another point of discussion. DeLauer acknowledges its mental resilience benefits but is sceptical about its metabolic impact. “Most of the cold therapy benefits are going to come from chronic exposure for longer periods of time,” he notes.
Workout Supplements
During workouts, Wahlberg consumes creatine and branched-chain amino acids (BCAAs). DeLauer finds the timing of creatine consumption irrelevant but comments on BCAAs: “BCAAs have largely been debunked for lack of a better way of saying it. Essential amino acids (EAAs) are where it’s at.”
Post-Workout Meal
Wahlberg’s post-workout meal consists of five eggs, a pork chop, wild smoked salmon, Greek yoghurt with berries, and green juice. DeLauer commends the high protein intake but questions the necessity of such a large meal soon after a workout. “You can have a lot of protein in one sitting,” he says, referring to recent studies. However, he suggests consolidating this meal with a later one to streamline nutrient intake.

Mid-Morning and Lunch
At 11 a.m., Wahlberg eats chicken breast, chicken thigh, sweet potato, broccoli, a bowl of mixed berries, and a handful of nuts. DeLauer points out that this might be excessive, especially considering his demanding schedule. “He could probably get by with a little less food at that point,” he advises, also suggesting a better mix of fats like macadamia nuts for a balanced diet.
Afternoon Meal
Wahlberg’s 2 p.m. meal is lighter, with sashimi, crab salad, cucumber, and some chicken breast. DeLauer highlights the low-carb nature of Wahlberg’s diet, noting that it might be overly restrictive given his activity level. He proposes consolidating this with the 11 a.m. meal for better nutrient timing.
Dinner
Dinner includes a steak or seafood with vegetables. DeLauer is again impressed by the protein focus but suggests incorporating more monounsaturated fats for a rounded diet.
Overall Diet Analysis
DeLauer appreciates Wahlberg’s focus on protein, fasting, and minimal supplements. “His supplement regime is relatively minimal, and he focuses on rest and recovery, letting the diet do the work,” DeLauer states. However, he sees room for improvement in fat variety and meal consolidation.

Mark Wahlberg’s diet is effective but not without its flaws. Thomas DeLauer’s critique highlights the importance of balanced nutrition and smart meal timing. Wahlberg’s regimen, while rigorous, can benefit from minor adjustments to enhance its effectiveness further. For those looking to emulate his success, these insights provide valuable guidance on optimising a diet for fat loss and muscle maintenance.
In conclusion, Wahlberg’s routine showcases the dedication required to maintain peak physical condition at any age. With expert advice from Thomas DeLauer, even small tweaks can lead to significant improvements in health and performance.
