Healthy weight gain

Gaining weight the healthy way means building muscle and strength with nutritious food — not filling up on sweets and fried food.

The basics

+300–500

kcal a day above your needs is a gentle surplus

0.25–0.5 kg

a week is a realistic, healthy pace

1.6 g

protein per kg body weight supports muscle growth

5–6

meals and snacks a day make it easier to eat more

8 methods that work

Key

Eat in a small calorie surplus

Add 300–500 kcal a day. Track your weight weekly and adjust.

Eat more often

Three meals and two or three snacks — smaller portions are easier than huge meals.

Choose energy-dense healthy foods

Nuts, peanut butter, tahini, olive oil, avocado, dates, dried fruit, whole milk, cheese.

Protein at every meal

Eggs, chicken, fish, meat, legumes, yoghurt and labneh support muscle growth.

Strength train 3 times a week

Lifting weights or bodyweight exercise turns extra food into muscle, not just fat.

Drink your calories

Homemade smoothies with milk, banana, oats and peanut butter add 500+ kcal easily.

Don't fill up on water before meals

Drink between meals instead, so you have room for food.

Sleep 7–9 hours

Muscle grows during recovery; poor sleep also reduces appetite.
