What percentage of Doug's diet should come from lean meats/beans and milk groups?

In a balanced diet, the recommendation for protein sources, which include lean meats, beans, and milk, typically falls within the range of 25% to 35% of total caloric intake. The choice of 25% reflects a reasonable proportion for most individuals, as it ensures sufficient protein for muscle maintenance, repair, and overall bodily functions without excess saturated fats that can come from higher intakes of red meats.

The specific recommendation of 25% allows for a healthy distribution of macronutrients, accommodating other essential food groups like fruits, vegetables, and grains, which are also crucial for a well-rounded diet. This percentage helps individuals maintain energy levels and supports metabolic processes while promoting weight control, especially when paired with healthy lifestyle choices.

While higher percentages may benefit certain individuals depending on their dietary needs, including athletes or those engaging in vigorous physical activity, 25% serves as a good baseline for many, balancing health, nutritional diversity, and weight management.
