1) “Eyeballing” Portions Instead of Measuring

Why it hurts: A “tablespoon” of peanut butter can swing 50–100 calories. Those add up fast.

Fix:
- Use a digital food scale for proteins and calorie-dense add-ons (oils, nut butters, dressings) for 1–2 weeks to recalibrate your eye.
- Standardize your scoop sizes (e.g., 15 g PB, 5 g olive oil) and save them as defaults.
- Pre-log dinner first, then fit lunch/snacks around it to hit targets without surprises.

2) Under-Eating Protein (Especially Early in the Day)

Why it hurts: Protein controls hunger, preserves muscle, and steadies energy. Most beginners eat <0.7 g/lb body weight.
Fix:
- Anchor breakfast with 25–40 g protein (eggs + yogurt; shake + fruit).
- Distribute protein across 3–4 meals; don’t save it all for dinner.
- Batch-cook a lean protein so it’s “grab-and-go.”

3) Being “Perfect” Monday–Thursday… then Weekend Chaos

Why it hurts: A single high-calorie day can erase a full week’s deficit.
Fix:
- Plan 1 flexible meal each weekend day (same calories, foods you enjoy).
- Keep protein steady; flex carbs/fats within your total.
- Use maintenance-calorie days strategically for events, then return to plan.

4) Forgetting Liquid Calories and “Bites, Licks, Tastes”

Why it hurts: Creamers, dressings, and “a quick bite while cooking” easily add 200–400 kcal/day.
Fix:
- Log all liquids (coffee add-ins, juices, sports drinks).
- Pre-portion dressings/oils; switch to lighter swaps where it matters to you.
- Keep a simple “BLT” note in your tracker for honesty (Bites-Licks-Tastes).

Quick swaps that save 100–250 kcal:
- Latte → Americano + splash of milk
- Heavy dressing → measured vinaigrette or yogurt-based dressing
- Cooking oil → measured spray + nonstick pan

5) Changing Too Many Things at Once

Why it hurts: Overwhelm leads to inconsistency, and inconsistency stalls progress.
Fix (Rule of 1):
- Pick one lever/week (e.g., “hit protein,” or “measure dinner”).
- Maintain it 6/7 days; only then add the next habit.
- Track what worked each week and repeat it.

Put It Together: A 5-Minute Macro Setup
- Set a protein target that fits your day (e.g., 130–160 g).
- Pre-log dinner → add lunch → fill breakfast/snacks around gaps.
- Batch one protein + one carb (e.g., chicken + rice) and keep a default veggie.
- Measure oils, dressings, nut butters; eyeball low-cal veg.

FAQs (New to Macros)
Do I need a scale forever? No—2 weeks of measuring trains your eye; then spot-check high-calorie items.
What if I go over on carbs or fat? Keep protein on target and adjust the next meal. Trends matter more than single meals.
How fast should I see results? Most see better energy/hunger in 3–7 days and measurable changes in 2–4 weeks if consistent.

Mini Checklist
- Measure oils/dressings for 2 weeks
- 25–40 g protein at breakfast
- Pre-log dinner; fill the rest
- One flexible weekend meal, protein steady
- Change one thing/week (Rule of 1)
