A fitness content creator known as Nicolas Renteria is facing scrutiny online after his publicly shared “what I eat in a day” video sparked discussion over whether his diet is both nutritionally complete and consistent with the advice he gives his audience.
Renteria, known for his notably lean physique, recently claimed that his approach helps him “stay lean year round without losing strength.”

Based on the meals shown in the video, his estimated daily intake comes to roughly 2,000 calories, 204 to 205 grams of protein, 257 grams of carbohydrates, and just 25 grams of fat.
The fat intake has become one of the biggest points of concern. At around 25 grams per day, many argue it falls well below the amount typically recommended to support healthy hormone production, including testosterone, particularly for someone engaged in regular strength training.


Beyond macronutrients, the diet has also drawn criticism for its estimated micronutrient profile. Based on the foods shown, vitamin A appears to provide only around 17% of recommended daily intake, while vitamin D is virtually absent.
Calcium intake also appears to be significantly below recommended levels, raising concerns for bone health and recovery in someone lifting weights regularly. Manganese intake is estimated at roughly half the recommended 2.3 milligrams per day for men, while omega-3 fatty acids are nearly nonexistent despite their important role in brain function, cell structure, and inflammation management.

The discussion has also highlighted an apparent contradiction between Renteria’s nutritional messaging and his own eating habits. While he has spoken critically about high carbohydrate consumption, the meals shown in the video add up to approximately 257 grams of carbohydrates over the course of the day.

For comparison, many physique athletes and individuals training for muscle growth regularly consume considerably more carbohydrates to support performance and recovery.

Some observers have also suggested that Renteria’s eating habits may reflect a lingering fear of weight regain following his previously documented weight-loss journey. Such behavior is not uncommon among people who have undergone major body transformations, as maintaining extreme leanness can sometimes lead to overly restrictive dietary choices.
