You’ve started eating more and trying to bulk up. But the scale won’t budge. Your arms still look the same. And you’re starting to wonder:
"Am I just someone who can’t gain weight?"
The answer is no. You can absolutely gain size. But here’s the truth:
Most naturally skinny guys think they’re eating enough... but they’re not.
Here’s exactly what’s going wrong and how to fix it 📉

Mistake #1: You’re Not Tracking Calories
Guessing how much you’re eating is one of the biggest reasons skinny guys stay small.
You eat a big lunch, have a protein shake or two, and figure you’ve hit 3,000 calories. But when you track it? It’s more like 1,900.
📅 Fix it: Track your calories for a full week. Use MyNetDiary or MyFitnessPal. Aim for 33–38 calories per kg of bodyweight per day to bulk (e.g., 70kg guy = ~2,500–2,660 calories).
Mistake #2: You’re Not Eating Enough Protein
Even if you’re getting the calories right, your macros might be off.
Protein is essential for muscle growth. And if you’re not eating enough, you won’t build size, even in a surplus.
🍽️ Fix it: Aim for 2g of protein per kg of bodyweight per day. Split this across 3–4 meals. Use lean meats, eggs, dairy, protein powder, or Greek yoghurt to hit your targets.
Mistake #3: You’re Not Training Hard Enough (or Smart Enough)
If you’re not pushing your muscles to grow, all that food just gets stored as fat.
The gym isn’t just about lifting weights. It’s about training for progression.
📈 Fix it: Follow a structured program. Track your lifts. Push for progressive overload: more reps, more weight, or more sets over time. Focus on compound movements and include direct work for arms, chest, back and legs.
Mistake #4: You’re Not Consistent Enough
You smash 1–2 big days of eating, then miss meals for the next 3. You go hard in the gym for 2 weeks, then get "busy."
This stops your progress in its tracks.
📊 Fix it: Muscle gain takes time. You need to stay consistent for months. Prepare meals in advance. Track your workouts. Prioritise recovery. You don’t need perfection, but you do need consistency.
