Losing weight can improve your health, boost your energy, and help you feel more confident. But not all weight loss methods are safe or effective in the long run. To protect your health and keep the results, it’s important to understand how weight loss really works — and what makes it healthy.
To lose weight, your body must burn more calories than it takes in. This is called a calorie deficit. Your body uses calories for energy — not just for movement, but also for basic functions like breathing, digestion, and maintaining body temperature.
When you eat fewer calories than your body needs, it starts to use stored energy — first from glycogen and fat, and sometimes even muscle tissue. This is why how you lose weight matters just as much as how fast.
A healthy and sustainable rate of fat loss is around 0.5 to 1% of your body weight per week. For example:
If you weigh 80 kg, that’s around 0.4 to 0.8 kg per week.
If you weigh 100 kg, that’s around 0.5 to 1 kg per week.
This slow and steady approach gives your body time to adapt. It helps prevent extreme hunger, hormonal changes, and mood swings, and makes it easier to keep the weight off.
Some people try to lose weight faster by eating much less — but that can be risky. A very low-calorie diet might give quick results at first, but it also increases the chance of:
Muscle loss
Slower metabolism
Low energy and poor training performance
Nutrient deficiencies
Rebound weight gain (yo-yo effect)
When your body loses muscle, your metabolism slows down, and you burn fewer calories even at rest. That’s why many people regain weight after a very strict diet.
To avoid losing muscle, it’s important to do resistance training (strength training) during weight loss. This tells your body to keep muscle and burn fat instead.
Strength training also improves body shape, posture, and metabolism. Even just 2 sessions per week of weight training can make a big difference.
During weight loss, protein is your best friend. Here’s why:
It protects your muscle during a calorie deficit.
It reduces hunger and helps you feel full.
It supports recovery after training.
Aim for 1.6 to 2.2 grams of protein per kilogram of body weight per day. For example, someone who weighs 70 kg should eat 112–154 grams of protein per day.
Good sources include: chicken, fish, lean beef, eggs, cottage cheese, Greek yogurt, tofu, tempeh, legumes, and protein powder.
Many people think they must avoid sweets, bread, or fast food completely. But there are no bad foods — only bad diets.
What matters most is:
Your total calorie intake
Your protein intake
Getting enough vitamins, fibre, and healthy fats
You can eat your favorite foods in moderation and still lose fat — as long as you are in a calorie deficit and meet your nutrient needs.
Be consistent, not perfect.
Don’t rely only on the scale — track your progress with photos, measurements, or how your clothes fit.
Be patient. Real, lasting fat loss takes time.
Focus on habits, not quick fixes.
