---

To address your request for a food calorie calculator and portion guide, it's essential to understand the importance of tracking food intake and managing portion sizes for maintaining a healthy diet. While I cannot provide you with a physical document, I can guide you through the process of calculating food calories and understanding portion sizes.


Understanding Food Calories
Calories are a measure of energy that food provides to our bodies. 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 calculate the total calorie content of a meal, you need to know the amount of each macronutrient present in the food you are consuming. This information can typically be found on food packaging or in nutritional databases.


How to Calculate Calories
1. Read Nutrition Labels: Most packaged foods have a nutrition label that lists the number of calories per serving. Pay attention to the serving size, as it can be misleading.


2. Use a Food Diary or App: Keeping a food diary or using a mobile app can help you track your daily intake. Many apps have built-in databases of foods and their calorie counts.

3. Portion Sizes: Familiarize yourself with standard portion sizes. For example:
- A serving of meat is typically about the size of a deck of cards (3-4 ounces).

- A serving of pasta is about the size of a fist (1 cup cooked).

- A serving of vegetables is about the size of your hand (1 cup raw or ½ cup cooked).

4. Calculate Total Calories: Multiply the grams of each macronutrient by their respective calorie values and sum them up. For example, if a food item has 10 grams of protein, 20 grams of carbohydrates, and 5 grams of fat:
- Protein: 10g x 4 = 40 calories
- Carbohydrates: 20g x 4 = 80 calories
- Fat: 5g x 9 = 45 calories
- Total = 40 + 80 + 45 = 165 calories

Portion Guide
A portion guide can help you understand how much of each food group you should consume daily. Here’s a general guideline based on dietary recommendations:
- Fruits: 2 servings (1 medium fruit or 1 cup of berries)
- Vegetables: 3 servings (1 cup raw or ½ cup cooked)
- Grains: 6 servings (1 slice of bread, ½ cup cooked rice or pasta)
- Protein: 5-6 ounces (lean meats, poultry, fish, beans)
- Dairy: 2-3 servings (1 cup of milk or yogurt, 1.5 ounces of cheese)
- Fats: 2-3 tablespoons (healthy oils like olive oil, nuts)

Additional Resources
For more detailed information, consider visiting reputable nutrition websites or databases such as the USDA FoodData Central or the National Institutes of Health (NIH) resources. These platforms provide comprehensive information on food composition, including calorie counts and nutrient breakdowns.


Conclusion
Tracking your food intake and understanding portion sizes are crucial steps in managing your diet effectively. While I cannot send you a physical copy of a calorie calculator or portion guide, I hope this information helps you in your journey toward healthier eating habits. If you have further questions or need personalized advice, consulting with a registered dietitian or nutritionist can provide tailored guidance based on your specific health needs and goals.
