Proper Amounts of Carbs, Proteins, and Fats in a Diet
The recommended macronutrient distribution for a balanced diet, based on the U.S. Dietary Guidelines for Americans and the Institute of Medicine, is expressed as a percentage of total daily calories for most healthy adults (assuming a ~2,000-calorie diet). Absolute grams vary by individual needs (age, sex, weight, activity level), but here’s the general Acceptable Macronutrient Distribution Range (AMDR):
• Carbohydrates: 45–65% of daily calories (225–325g on 2,000 calories). Prioritize complex carbs (whole grains, vegetables) for fiber and sustained energy.
• Proteins: 10–35% of daily calories (50–175g on 2,000 calories; minimum RDA is 46g for women, 56g for men, or 0.8g/kg body weight). Supports muscle repair and satiety.
• Fats: 20–35% of daily calories (44–78g on 2,000 calories). Focus on unsaturated fats; limit saturated fats to <10% and avoid trans fats.
A balanced split (e.g., 55% carbs, 20% protein, 25% fat) reduces chronic disease risk.

Foods for a Balanced, Healthy Diet
Since you are not likely to get ALL of the basic nutrients for your body in the course or one day, or with the same foods every day, I have created a list of food items (no recipes) for a ~2,000-calorie/day diet, emphasizing variety across food groups:
Fruits: Berries, citrus, apples, melon, pineapple, grapes, bananas
Vegetables: Leafy greens, cruciferous (broccoli, Brussels), root (sweet potatoes, carrots), peppers, onions
Whole grains: Oats, quinoa, brown rice, barley, whole-grain pasta, cereal
Proteins: Chicken, turkey, fish, tofu, tempeh, lentils, beans, eggs, yogurt
Healthy fats: Avocado, olive oil, nuts, seeds, nut butters
Dairy/Alternatives: Low-fat milk, Greek yogurt, kefir, fortified soy milk
Key Principles or Rules of Thumb
Fruits and/or Veggies: 5+ servings/day (colorful for antioxidants, e.g., vitamin C from peppers).
Grains: Mostly whole (oats, quinoa for fiber/B vitamins).
Protein: Lean meats or plant-based (fish 2x/week for omega-3s; legumes for variety).
Fats: Nuts, seeds, avocado, olive oil.
Hydration: Water, herbal tea; limit dairy/alternatives to 1–2 servings/day.
Carbohydrates: Carbs differ because quality and proportion matter far more than the sheer number of grams. Here’s a breakdown of what the healthiest carbohydrate pattern looks like in an optimal, balanced diet:
How Much Carbohydrate: For most adults (based on a ~2,000-calorie diet):
45–65% of total calories should come from carbohydrates or roughly 225–325 grams per day. However, the healthiest end of this range depends on your lifestyle:
Active individuals: closer to 55–65% (to replenish glycogen)
Moderately active or weight-conscious: 40–50% can be ideal
Metabolic issues (e.g., insulin resistance): often better near 35–45%, focusing on slow-digesting, fiber-rich carbs
Emphasize whole, minimally processed plant foods, which provide fiber, vitamins, minerals, and phytonutrients.
As a rule of thumb, ½ of your carbs should come from fruits and vegetables, ¼ should come from whole grains, and ¼ from legumes/tubers.

Examples
Health Benefit
Whole grains (3-5 servings/day)
Oats, quinoa, brown rice, barley, farro, bulgur, 100% whole-grain bread or pasta
Sustained energy, B-vitamins, fiber
Vegetables (especially non-starchy)
Leafy greens, broccoli, peppers, carrots, cauliflower
Low-calorie, nutrient-dense, gut health
Fruits (2-3 servings/day)
Berries, apples, oranges, bananas, kiwis
Antioxidants, hydration, potassium
Legumes (1-2 servings/day)
Lentils, beans, chickpeas, peas
Protein + slow carbs, excellent fiber
Tubers (moderation)
Sweet potatoes, potatoes (with skin)
Resistant starch, beta carotene
As you can see, carbohydrates are in many different types of foods, they are not just breads and pastries and they serve many functional roles in your diet. They are necessary for:
fuel: main energy source for brain and muscles
fiber: nourishes the gut microbiome, especially oats, onions, bananas, and legumes
hormonal balance: prevents cortisol spikes and preserves thyroid and reproductive health
micronutrients: whole carbs carry magnesium, potassium, B vitamins, polyphenols
Generally Speaking: These Foods Should Be Avoided
In a general sense, certain foods and dietary habits should be minimized or avoided to maintain a healthy diet, as they contribute to chronic conditions like obesity, heart disease, diabetes, and inflammation. These are broadly applicable recommendations based on evidence from health authorities like the WHO and American Heart Association:
Added Sugars: Limit to <10% of daily calories (ideally <25g/day). Avoid sugary drinks (soda, energy drinks, sweetened coffee/tea), candies, desserts (cakes, cookies), and processed cereals. Excess sugar spikes blood glucose and increases fat storage.
Trans Fats: Avoid entirely (0% of calories). Found in partially hydrogenated oils in some margarines, fried fast foods, packaged baked goods (e.g., doughnuts, crackers). Linked to heart disease.
Excess Saturated Fats: Limit to <10% of calories (~22g on 2,000 calories). Reduce fatty cuts of red meat (e.g., ribs), processed meats (bacon, sausage), butter, and full-fat cheese. Opt for leaner proteins or plant-based fats.
Refined Grains: Minimize white bread, white rice, pasta, and processed snacks (chips, pretzels). They lack fiber and spike blood sugar; choose whole grains instead.
Excess Sodium: Limit to <2,300mg/day (ideally ~1,500mg). Avoid processed foods (canned soups, deli meats, frozen meals), fast food, and salty snacks (chips, salted nuts). High sodium raises blood pressure.
Excess Alcohol: Limit to 1 drink/day for women, 2 for men (1 drink = 1.5 oz 80-proof liquor, ~97 calories). Avoid binge drinking; excess strains the liver and adds empty calories.
Highly Processed Foods: Avoid items with long ingredient lists, artificial additives, or preservatives (e.g., packaged snacks, instant noodles, sugary yogurts). They often combine high sugar, sodium, and unhealthy fats.
Why Avoid These? These contribute negligible nutrients while increasing risks of weight gain, cardiovascular issues, and insulin resistance. Focus on whole, minimally processed foods (like those in the weekly plan) to maximize nutrient density. If you have specific health concerns (e.g., diabetes, hypertension), consult a dietitian for tailored advice.
The following is a listing of the healthy foods mentioned in above and some others. They are categorized by their primary nutrient type—carbohydrates, proteins, fats, or micronutrients (vitamins/minerals). Many foods contribute to multiple nutrients, but I’ve assigned each based on its most prominent contribution in a balanced diet, per standard nutritional science (e.g., USDA, NIH).
Carbohydrates (Primary Energy Sources) These provide complex carbs and/or fiber for sustained energy and digestion:
Oatmeal, Quinoa, Sweet potato, Butternut Squash, Whole-wheat roll, Brown rice, Farro, Whole-wheat tortilla, Couscous. Rye bread, Whole-grain cereal, Whole-wheat pita, Wild rice, Banana, Pear, Orange, Grapes, Blueberries, Strawberries, Mango Pomegranate, Raspberries, Pineapple, Corn, Dried fruit
Proteins (Muscle Repair, Satiety) These are rich in amino acids for tissue repair and maintenance:
Chickpeas, Salmon, Turkey, Tuna (canned in water), Chicken breast, Tofu, Lean beef, Cod, Egg, Lentils, Black beans, Greek yogurt, Cottage cheese, String cheese, Sardines, Mackerel, Tempeh, Edamame, Pork Tenderloin, Lentils (Red)
Fats (Energy, Cell Function) These provide healthy fats (mostly unsaturated) for heart health and satiety:
Almonds, Avocado, Olives, Chia seeds, Flaxseeds, Pumpkin seeds
Walnuts, Mixed nuts (unsalted), Peanut butter, Almond butter, Tahini, Hemp Seeds, Sunflower Seeds, Olive Oil (Extra Virgin, Flaxseed Oil, Macadamia Nuts
Micronutrients (Vitamins/Minerals) These are dense in vitamins, minerals, and antioxidants for overall health (low in calories, high in nutrients):
Cherry tomatoes, Cucumber, Broccoli, Spinach’ Carrots, Bell peppers, Zucchini, Mixed greens, Brussels sprouts, Kale, Mushrooms, A Beets, Cauliflower, Red Cabbage, Swiss Chard, Arugula, Shiitake Mushrooms, Seaweed (Nori, Wakame), Kefir, Parsley, Garlic, Asparagus, Green beans, Red onion, Lime, Feta, Low-fat milk, Soy milk
Select your meals from this list of foods and you will be eating what many consider a healthy diet. There are many recipes that can make each of these foods be tastier than you might imagine.
