Certainly! It seems you are looking for a food calorie calculation and portion guide, which is an essential tool for anyone interested in managing their diet and understanding nutritional intake. While I cannot send you physical materials, I can provide you with a comprehensive overview of how to calculate food calories and the importance of portion control in a healthy diet.


Understanding Food Calories
Calories are a measure of energy that food provides to the body. Each macronutrient contributes a different number of calories per gram:
- Carbohydrates: 4 calories per gram
- Proteins: 4 calories per gram
- Fats: 9 calories per gram
- Alcohol: 7 calories per gram
To maintain a healthy weight, it’s crucial to balance the number of calories consumed with the number of calories burned through daily activities and exercise.

How to Calculate Daily Caloric Needs
1. Determine Basal Metabolic Rate (BMR): This is the number of calories your body needs at rest to maintain basic physiological functions. You can use the Mifflin-St Jeor Equation:
- For men: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) + 5
- For women: BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (years) - 161
2. Calculate Total Daily Energy Expenditure (TDEE): Multiply your BMR by an activity factor that corresponds to your lifestyle:
- Sedentary (little or no exercise): BMR × 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
- Very active (hard exercise/sports 6-7 days a week): BMR × 1.725
- Super active (very hard exercise, physical job, or training twice a day): BMR × 1.9

Portion Control and Food Guides
Understanding portion sizes is crucial for managing caloric intake. Here’s a general guideline for daily servings based on a balanced diet:
- Dairy: 1-2 cups (preferably low-fat)
- Vegetables: 3 cups (focus on a variety of colors, especially dark leafy greens)
- Fats: 2-3 tablespoons (preferably from healthy sources like olive oil)
- Protein: 4 ounces (includes meat, fish, eggs, beans, and legumes)
- Fruits: 2 servings (whole fruits are preferable to juices)
- Grains: 3-6 servings (whole grains are recommended)

Tools for Caloric Calculation
1. Food Labels: Always check the nutrition facts on food packaging. They provide information on serving sizes, calories, and nutrient content.

2. Nutrition Apps: Consider using apps like MyFitnessPal or Cronometer, which allow you to log your food intake and calculate calories easily.

3. Portion Control Tools: Use measuring cups, a food scale, or visual cues (like comparing portion sizes to common objects) to help manage serving sizes.


Conclusion
While I cannot send you a physical guide, I encourage you to utilize the resources available online, such as the USDA's MyPlate website, which provides comprehensive information on food groups and portion sizes. Additionally, local health departments or nutritionists can provide tailored advice and resources specific to your needs.
