What happens if you eat 3 eggs every day?

We are not all the same: individual considerations
Although “3 eggs a day” sounds like a specific number, it doesn’t mean it’s the perfect solution for everyone. You have to consider the context of your entire diet:

If the diet already includes a lot of red meat, fried foods, butter, saturated fats, then adding 3 eggs could “weigh” more than recommended.
People with liver problems, a predisposition to high cholesterol, or certain metabolic diseases should do so under professional supervision.
Lifestyle also matters: physical activity, other foods consumed, and general health habits.
