## 3. How to Optimize Your Diet for Energy & Focus
2. **Mind Your Timing** - **Morning**: protein + carbs (e.g., oatmeal with Greek yogurt and berries). - **Mid‑day Snack**: a handful of almonds + an apple – prevents afternoon slump. - **Evening**: light, easy to digest (e.g., grilled fish with veggies) – avoids discomfort.
3. **Hydration is Key** - Aim for 2–3 L per day; water before meals can help you feel full and reduce overeating.
4. **Avoid Heavy, Greasy Foods Before Bed** - These can cause reflux or indigestion that disrupts sleep—opting for lean protein and veggies keeps your stomach comfortable.

## Quick Reference: Ideal Daily Meal Pattern
| Time | Main Focus | Example Food Choices | |------|------------|----------------------| | **Breakfast (6–8 am)** | Balanced carbs + protein + healthy fat | Oatmeal with berries & a handful of nuts; or scrambled eggs with spinach and whole‑grain toast. | | **Mid‑morning Snack (10 am)** | Light protein + fiber | Greek yogurt with sliced apple, or hummus with carrot sticks. | | **Lunch (12–1 pm)** | Protein + complex carbs + veggies | Grilled chicken breast, quinoa salad with mixed greens and olive oil vinaigrette. | | **Afternoon Snack (3–4 pm)** | Healthy fat + protein | Handful of almonds or a boiled egg; pair with a piece of fruit if needed. | | **Dinner (6–7 pm)** | Lean protein + veggies, limited carbs | Baked salmon, roasted broccoli and sweet potato wedges. | | **Evening (if hungry)** | Light snack** | Low‑fat Greek yogurt with berries or a small handful of pistachios. |
\* **Pistachio** is an excellent snack because it contains healthy fats, protein, and potassium—helpful for blood pressure control.
#### 3.1 Portion Control - **Protein:** Aim for 3–4 oz (about the size of your palm) per meal. - **Vegetables:** Fill half your plate with non‑starchy veggies (leafy greens, peppers, tomatoes). - **Starches:** Limit to a small portion—e.g., ½ cup cooked rice or pasta. - **Fats:** Use healthy fats sparingly. A tablespoon of olive oil for cooking or salad dressing is adequate.
#### 3.2 Sample Daily Menu
| Meal | Food | Portion | |------|------|---------| | Breakfast | Scrambled eggs (1 egg + 1 egg white) with spinach, tomato, and a sprinkle of feta | 1 plate | | Snack | Low‑fat Greek yogurt (6 oz) with fresh berries | 1 cup | | Lunch | Grilled chicken breast (3 oz) over mixed greens with cucumber, carrot, cherry tomatoes; dressed with olive oil & lemon | 1 bowl | | Snack | Apple slices with 1 tbsp almond butter | 1 serving | | Dinner | Baked cod (4 oz) seasoned with herbs; side of steamed broccoli and quinoa (½ cup cooked) | 1 plate |
**Rationale**
- **Protein:** Lean meats, fish, dairy, nuts, and legumes supply high‑quality protein without excessive saturated fat. - **Fat:** Emphasis on unsaturated fats (olive oil, nuts, fatty fish) to improve lipid profile; limited saturated fat (<10 % of calories). - **Carbohydrate:** Complex carbs from whole grains and vegetables provide fiber (~25 g/day) to aid satiety, glycemic control, and gut health.

## 3. Physical‑Activity Guidance
| Goal | Recommended Activity | Frequency | Duration | Intensity | |------|-----------------------|-----------|----------|-----------| | **Weight‑loss** | Aerobic exercise (brisk walking, cycling, swimming) + resistance training | 5–6 days/week | 30–60 min/day | Moderate (50–70 % HRmax) | | **Cardiometabolic health** | Continuous moderate‑intensity or interval training | ≥3 days/week | 20–40 min | Variable – include high‑intensity intervals 1–2 ×/week | | **Muscle maintenance** | Resistance training (full‑body) | 2–3 days/week | 30–45 min | Focus on compound lifts, progressive overload |
*Key points:* - Combine aerobic and resistance work to preserve lean mass while promoting fat loss. - Interval sessions can improve insulin sensitivity more efficiently than long steady‑state cardio.

### 4. Sample Structured Program (8‑Week)
| Day | Focus | Workout | Calories & macronutrients | |-----|-------|---------|----------------------------| | Mon | Upper body resistance + HIIT | Bench press, rows, shoulder press; 20 min HIIT on bike | ~2 200 kcal: 30 % protein (165 g), 25 % fat (61 g), 45 % carbs (247 g) | | Tue | Lower body resistance + steady‑state cardio | Squats, deadlifts, lunges; 30 min treadmill (moderate pace) | Same macronutrient split | | Wed | Core + moderate HIIT | Plank variations, Russian twists, kettlebell swings; 15 min HIIT on rower | Same calories but reduce carbs to 220 g for recovery | | Thu | Active recovery | Yoga or light swim | Reduce calories by 200 kcal, maintain protein high (30 %) | | Fri | Full‑body circuit + HIIT | Circuit of push‑ups, pull‑downs, step‑ups; finish with 10 min HIIT on bike | Same macronutrient split | | Sat | Long cardio + mobility | 45‑minute jog or cycle + foam rolling | Slightly higher carbs (250 g) to replenish glycogen | | Sun | Rest day | No structured exercise | Focus on protein and healthy fats, no carb restriction |
### How the Plan Helps
- **High protein**: preserves lean muscle mass during fat loss. - **Calorie deficit**: forces the body to use stored fat for energy. - **Regular cardio/HIIT**: burns calories and increases resting metabolic rate. - **Adequate carbs on active days**: fuel workouts, preventing muscle loss. - **Recovery days**: allow muscles to repair, preventing overtraining.

## 3. When & How to Cut Body Fat
| Phase | Goal | What to Expect | |-------|------|----------------| | **Initial fat‑loss (1–4 weeks)** | Drop ~0.5–1 lb per week. | Mild hunger, slightly more tiredness during workouts. | | **Plateau phase (4–8 weeks)** | Body adapts; weight may stall. | Consider minor tweaks: lower carbs 2 days/week or increase cardio. | | **Maintenance (after fat‑loss)** | Keep new body composition stable. | Eat at maintenance calories, re‑evaluate macros yearly. |
**How to know when to stop?**
- If your measurements (waist, hips) are stable for >3 months and you feel energized. - If the scale stops moving despite consistent effort.

### 3️⃣ Practical Tips for Eating Well During a Marathon
1. **Hydration** - Start each day hydrated: ~2 L of water before bed and another 500‑750 mL in the morning. - Carry a small bottle or use race hydration stations every 5–10 km.
2. **Breakfast on the Go** - Overnight oats, banana with peanut butter, or a protein bar are quick options if you’re running early in the morning.
3. **Post‑Run Fuel** - Within 30 minutes of finishing, grab a small snack: Greek yogurt + berries, a banana + handful of nuts, or a protein shake. - Aim for ~20–25 g of protein and some carbs (e.g., fruit or whole‑grain toast).
4. **Meals Between Races** - Keep portions moderate; focus on lean proteins (chicken breast, fish), complex carbs (sweet potatoes, brown rice), and plenty of vegetables. - If you’re training hard, slightly increase the portion size or add a healthy snack to compensate.
5. **Hydration** - Drink water consistently throughout the day. After races, rehydrate with water plus electrolytes if sweating heavily.
6. **Recovery Foods** - Chocolate‑milk (low‑fat) is great after a hard session: it’s rich in carbs and protein, plus it's enjoyable. - Alternatively, try Greek yogurt with fruit or a banana smoothie for quick replenishment.
