Good Fat vs Bad Fat: Everything You Need to Know About Body Fat and Fitness

Day 18: Understanding Body Fat – Good Fat vs Bad Fat in Fitness

When we think of “fat,” it’s often seen as something negative. But did you know that not all fat is bad? Your body needs fat — the right kind, in the right amount — for energy, hormones, brain health, and more.

Today, let’s explore the different types of body fat, how it affects your fitness goals, and what to do to manage it effectively.

🧬 What is Body Fat?

Body fat is stored energy that your body saves for times when food or fuel is scarce. It’s essential for:

• Regulating temperature

• Protecting organs

• Producing hormones

• Absorbing fat-soluble vitamins (A, D, E, K)

But excess fat, especially the wrong type and in the wrong places, increases the risk of diseases like diabetes, heart issues, and hormonal imbalances.

🔍 Types of Body Fat

✅ 1. Essential Fat

• Minimum fat your body needs for basic function

• Found in bone marrow, organs, nervous system

• Women need ~10–13%, Men ~2–5%

✅ 2. Subcutaneous Fat

• Fat stored under your skin (visible fat)

• Pinchable fat on belly, arms, thighs

• Not always harmful unless excessive

✅ 3. Visceral Fat (The Dangerous One)

• Fat stored around internal organs (liver, intestines)

• Linked to insulin resistance, heart disease, inflammation

• Common in people with large bellies despite thin arms/legs

✅ 4. Brown Fat (Good Fat)

• Burns calories to produce heat

• Found more in babies and lean adults

• Scientists are exploring how to activate this fat

✅ 5. White Fat (Storage Fat)

📏 Ideal Body Fat Percentages

Group	Body Fat % (Healthy Range)

🧪 How to Measure Body Fat

🧍‍♂️ 1. Body Fat Calipers

• Budget-friendly and accurate with practice

🏥 2. DEXA Scan

• Use weekly to spot trends

💪 How to Reduce Unhealthy Body Fat

🥗 1. Create a Calorie Deficit

Burn more calories than you eat, through:

• Eating whole foods

• Reducing sugar and fried foods

• Portion control

🏃 2. Do More Strength Training

Muscle burns more calories than fat. Focus on:

• Squats, lunges, pushups, planks

• 3–4 sessions/week

❤️ 3. Incorporate Cardio

• Walk 10,000 steps/day

• Add HIIT or jogging 2–3 times/week

💧 4. Stay Hydrated

Water boosts metabolism and reduces cravings.

😴 5. Sleep at Least 7 Hours/Night

Sleep deprivation leads to fat gain and low energy.

🧘 6. Manage Stress

Practice yoga, journaling, or deep breathing. Chronic stress = more belly fat.

⚠️ Don’t Chase “Zero Fat”

• It’s a natural part of your body

• Instead of “losing fat,” aim to optimize body composition: more muscle, less excess fat

• Reduces shame and guilt around body image

• Helps you focus on health, not just looks

• Empowers you to make better lifestyle choices
