Main Nutrients

  • Carbohydrates – Your body’s main energy source.
    Examples: rice, bread, fruits.

  • Proteins – Build and repair tissues.
    Examples: eggs, chicken, lentils.

  • Fats – Support cell function and help absorb vitamins.
    Examples: nuts, oils, fish.

  • Vitamins – Support various body functions (e.g., Vitamin C boosts immunity).

  • Minerals – Important for bones, nerves, and muscles (e.g., calcium, iron).

  • Water – Essential for every process in your body.

Nutrition for Weight Loss (Fat Loss)

Goal: Reduce body fat while maintaining muscle and energy.

 Key Principles:

  • Calorie deficit: Eat fewer calories than you burn (aim for ~500/day less).
  • High protein: Helps keep you full and preserves muscle.
  • Low sugar & processed foods: Avoid empty calories.

  • Snack: Nuts or a protein shake
  • Dinner: Veggie stir-fry + tofu or paneer

Nutrition for Muscle Gain (Lean Bulk)

Goal: Build muscle while minimizing fat gain.

Key Principles:

  • Calorie surplus: Eat ~250–500 more calories per day.
  • High protein intake: 1.6–2.2g per kg of body weight.
  • Complex carbs: Fuel workouts and recovery.
  • Healthy fats: Support hormones and joint health.

Sample Daily Plan:

  • Breakfast: 4 eggs + whole wheat toast + banana

  • Snack: Whey protein + peanut butter toast

  • Lunch: Brown rice + chicken + spinach

  • Snack: Cottage cheese + almonds

  • Dinner: Salmon + sweet potato + broccoli

  • Post-workout: Protein shake + fruit

Nutrition for Special Conditions

(Choose based on your needs, or ask for one specifically.)

Examples:

  • Diabetes: Low GI foods, balance carbs + fiber, limit sugar.

  • PCOS: Low-carb + high-fiber diet, avoid dairy & sugar spikes.

  • Hypertension: Low salt, more potassium (bananas, leafy greens).

  • Thyroid: Include selenium (Brazil nuts), iodine (iodized salt), and avoid excess soy.

Protein – The Body’s Building Blocks

What It Does:

  • Builds and repairs muscles and tissues

  • Makes enzymes, hormones, and antibodies

  • Helps keep you feeling full

Daily Requirement:

  • Sedentary adults: ~0.8 g per kg body weight

  • Active individuals: 1.2–2.0 g per kg

  • Older adults & athletes: Higher needs

Best Sources:

  • Animal: chicken, fish, eggs, dairy

  • Plant: lentils, chickpeas, tofu, quinoa

Deficiency Symptoms:

  • Muscle loss

  • Weak immunity

  • Fatigue

  • Edema (swelling)

Too Much Protein?

  • Usually safe for healthy people

  • Can strain kidneys in pre-existing kidney disease

  • Excess calories still stored as fat
