Question 1

How many calories should I eat to lose weight?

Accepted Answer

Create a deficit of 300–500 calories below your TDEE (Total Daily Energy Expenditure). This produces 0.3–0.5 kg of fat loss per week — sustainable and safe. Use our TDEE calculator to find your exact number.

Question 2

How fast can I lose weight safely?

Accepted Answer

0.5–1% of bodyweight per week is the optimal rate. Faster than this risks muscle loss. For a 70 kg person, that's 350–700g per week. Slower rates are also fine — sustainability beats speed.

Question 3

Do I need to do cardio to lose weight?

Accepted Answer

No. Cardio is optional for fat loss — a calorie deficit through diet alone will lose weight. Cardio helps by increasing calorie expenditure, making the deficit easier to achieve without eating less.

Question 4

Why did my weight loss stop?

Accepted Answer

When you lose weight, your TDEE decreases. What was a 500 kcal deficit becomes smaller over time. Recalculate your TDEE and adjust calories down, or increase activity level.

Question 5

How much protein do I need to build muscle?

Accepted Answer

1.6–2.2g of protein per kg of bodyweight per day is optimal for muscle protein synthesis. Higher amounts (up to 3g/kg) may be useful during a cut to preserve muscle.

Question 6

Can I build muscle and lose fat at the same time?

Accepted Answer

Yes — this is called "body recomposition." It's most effective for beginners, those returning after a break, or people who are overweight. Advanced lifters should focus on one goal at a time.

Question 7

How many days per week should I train?

Accepted Answer

Training each muscle group 2× per week is optimal for hypertrophy. A 3-day full-body routine works great for beginners. 4–6 day splits are for intermediate and advanced lifters.

Question 8

What's progressive overload?

Accepted Answer

Progressive overload means consistently increasing the demands on your muscles over time — adding weight, reps, sets, or reducing rest time. Without it, your body has no reason to grow stronger.

Question 9

What are macros?

Accepted Answer

Macros (macronutrients) are protein, carbohydrates, and fat — the three main calorie sources. Protein and carbs have 4 kcal/g, fat has 9 kcal/g. Tracking macros gives you precision beyond just counting total calories.

Question 10

Is intermittent fasting effective?

Accepted Answer

IF works because it reduces your eating window, making it easier to eat fewer calories. It has no metabolic magic beyond this — any diet that creates a calorie deficit will produce fat loss.

Question 11

Is the keto diet the best for weight loss?

Accepted Answer

Keto is effective for those who prefer high-fat, low-carb eating. But research shows no metabolic advantage over other diets when calories and protein are matched — the best diet is the one you can follow consistently.

Question 12

Do I need to eat breakfast to lose weight?

Accepted Answer

No. "Breakfast is the most important meal" is a myth. Meal timing matters far less than total daily calories and protein. Eat when it fits your lifestyle and hunger signals.

Question 13

What is BMI?

Accepted Answer

BMI (Body Mass Index) is a ratio of weight to height squared. It's a screening tool, not a diagnosis — it doesn't account for muscle mass. A muscular athlete may have a "high" BMI while being healthy.

Question 14

What is TDEE?

Accepted Answer

TDEE (Total Daily Energy Expenditure) is the total calories you burn per day, including exercise and activity. It's your maintenance calorie level — eat below it to lose weight, above it to gain.

Question 15

How accurate are online calculators?

Accepted Answer

Online calculators use validated equations and are typically within ±10% of lab measurements for most people. They're excellent starting points — track your weight for 2–4 weeks and adjust based on actual results.

Question 16

What is my 1-rep max (1RM)?

Accepted Answer

Your 1RM is the maximum weight you can lift for one rep. Use our 1RM calculator to estimate it from your multi-rep sets without risk. It's used to set training percentages for strength programs.

Question 17

How long until I see results?

Accepted Answer

Strength improvements begin in 2–3 weeks (neural adaptation). Visible body composition changes typically appear after 4–8 weeks of consistent training and diet. Take progress photos monthly — the scale is unreliable week to week.

Question 18

Should I exercise when sore?

Accepted Answer

Mild DOMS (delayed onset muscle soreness) is fine to train through — it means you worked hard. Sharp or joint pain is a signal to rest. Active recovery (walking, light movement) often reduces soreness better than complete rest.

Question 19

How important is sleep for fitness?

Accepted Answer

Sleep is when muscle repair and growth hormone release peak. Consistently sleeping under 7 hours doubles injury risk, increases appetite, reduces training performance, and slows recovery. It is as important as nutrition and training.
