Building Muscle on a Budget: The Real Numbers
Building muscle requires eating above maintenance. People think "bulking" means spending double on food. It doesn't.
You need roughly 300-500 extra calories daily. That's one extra meal, not two.
Your Muscle-Building Calorie Target
A 70kg woman maintaining at 1,800 calories needs 2,100-2,300 to build muscle.
That's:
- Breakfast: 400 calories
- Lunch: 500 calories
- Dinner: 600 calories
- Snack: 400 calories
Total: 1,900 calories minimum (muscle building).
Cheap Calorie Sources for Bulking
You need more calories. Here's how to add them cheaply:
Carbs (Cheapest Calories)
Rice: 200 calories per cup cooked. Costs £0.25.
Pasta: 220 calories per cup cooked. Costs £0.20.
Bread: 80 calories per slice. Costs £0.15.
Oats: 150 calories per cup cooked. Costs £0.15.
A bowl of rice (£0.25) gives you 600 calories. It's the cheapest way to add calories.
Fats (Calorie Dense)
Oil: 120 calories per tbsp. Costs £0.05.
Butter: 100 calories per tbsp. Costs £0.10.
Nuts: 160 calories per ounce. Costs £0.50.
Adding oil to meals (cheap calories) is the budget bulker's secret.
Protein (Expensive But Necessary)
Eggs: 70 calories + 6g protein each. Costs £0.30.
Chicken thighs: 180 calories + 20g protein per 100g. Costs £0.50 per 100g.
Beans: 120 calories + 8g protein per 100g. Costs £0.10 per 100g.
For bulking, eggs are your friend. Calorie-dense for the price.

Building Muscle on This Budget
Eat this amount, train 3x per week with progressive overload, sleep 8 hours, repeat for 12 weeks.
You'll gain 3-5kg. Most will be muscle (roughly 75% muscle, 25% fat on a bulk).
This is how you actually build muscle on budget.
Tracking Your Bulking Progress
Week 1-2: Photos and weight. Baseline.
Weeks 3-8: Strength increasing (squat, press, rows all going up 10-20% total).
Week 9-12: Noticeably more muscle visible. Energy in gym is higher.
By week 12, you'll look different.
Frequently Asked Questions
Q: Will I get too fat bulking?
A: On a modest surplus (300 cal above maintenance), you'll gain roughly 0.25-0.5kg per week, with 75% being muscle. That's acceptable.
Q: How long should I bulk?
A: 8-12 weeks, then maintenance for 4 weeks, then decide: keep bulking or cut?
Q: Should I track calories exactly?
A: Roughly. Within 200 calories is close enough. Eat rice, protein, and a bit of oil daily. You'll hit it.
Q: What if I lose appetite?
A: Drink your calories instead. Milk + banana + peanut butter is liquid calories.
