A flying start in weight loss with intermittent fasting

Intermittent fasting is not a diet that you apply temporarily, but it is really a way of life. The idea is that you make peace with your body and that you only eat when you are hungry and not because you have to. You will soon notice that the weight decreases each week in a healthy and responsible way.

Patience and consistency are your best friends

Intermittent fasting is not a quick fix, but a sustainable way of living and building awareness. Don't expect instant weight loss — focus on getting to know your body. Start with achievable goals and build from there.

Many people start with the 16:8 schedule — 16 hours fasting, 8 hours eating — but beginners do better starting with 12:12 or 14:10. Your body needs time to adjust to a new eating rhythm.

The first two weeks are often the hardest. After that, most people report that their hunger decreases, their energy levels stabilise and they think less about food. That's the point where IF really starts to work.

Eat smartly during your eating window

If your goal is weight loss, it's tempting to eat very little during your meals. Don't do that. Your body needs nutrition to function well. Eating too little leads to more hunger, cravings and ultimately relapse.

Listen to your body and be kind to yourself. Making good choices only works if you don't starve yourself. Sufficient protein is essential here — it keeps you fuller for longer and helps preserve muscle mass.

A practical guideline: aim for 25 to 30 grams of protein per meal. Think eggs, Greek yoghurt, chicken, fish or legumes. That way you get through your eating window well without persistent hunger afterwards.

Test and discover what suits you

There is no single right way to start intermittent fasting. It's about finding an approach that's sustainable in your life. Here are three concrete steps to experiment with:

  • Consciously skip a meal. For example: no dinner after a generous restaurant lunch. Notice how your body responds.
  • Delay your first meal. Start your day with water or tea and only eat breakfast when you're genuinely hungry. For many people this gradually shifts to 10 or 12 o'clock.
  • Exercise on an empty stomach. Even a short walk counts. Many people find this energising rather than tiring.

Track how you feel: your energy levels, sleep quality and mood tell you more than the scales.

Nutrition remains the key

Going from three to two meals a day? Then it's even more important to choose nutritious, balanced meals. Not gigantic portions, but sufficient protein, healthy fats and fibre.

Good basic nutrition for IF looks like this:

  • Proteins: eggs, fish, chicken, cottage cheese, legumes
  • Healthy fats: avocado, olive oil, nuts, oily fish
  • Fibre: vegetables, fruit, whole grains

Hunger feelings often diminish over time, but be careful not to eat too little as a result. A lack of nutrients can lead to fatigue, fat storage and hormonal imbalance. Especially for women over 40, sufficient protein intake is not optional but essential.

Not for everyone

Intermittent fasting is not suitable for everyone. Do you have underweight, a history of eating disorders or a medical condition? Always consult a doctor before starting.

Be especially careful if you have:

  • Diabetes or blood sugar fluctuations
  • Low blood pressure
  • Use of medication
  • Pregnancy or breastfeeding
  • Problems with menstruation or fertility

When in doubt, always consult a doctor or dietitian. IF is a powerful approach, but must suit your health situation.

Intermittent fasting is a lifestyle

It's all about balance, rest and respect for your body. Eat because you're hungry, not because it's "time". And give yourself the space to grow in this new way of living.

Those who approach IF as a lifestyle rather than a diet achieve more sustainable results. No end date, no strict rules — but a more conscious relationship with nutrition, energy and your body.

With the right support you increase your chances of success and your comfort. Think of protein-rich food for your eating window, or a supplement that helps you keep your appetite under control during the fasting period.

Frequently asked questions about losing weight with intermittent fasting

That varies per person and depends on your food choices, activity level and starting weight. Most people notice a difference in energy levels and eating behaviour after two to four weeks. Weight loss is gradual — expect a sustainable pace of 0.5 to 1 kg per week with a healthy approach.

No, outside your eating window you don't eat. Water, black coffee and unsweetened tea are allowed. As soon as you take in calories, even from small snacks, you break your fast and stop the fat burning that occurs during fasting.

Not if you eat enough protein during your eating window. Aim for at least 0.8 to 1.2 grams of protein per kilogram of body weight per day. Combine IF with resistance exercises for maximum muscle preservation — especially important after the age of 40.

That depends on the person. Many people find IF easier to maintain than counting calories daily. By limiting the eating window, you often naturally eat less without keeping track. But the quality of your nutrition always remains the foundation.

Yes, but combining the two works better. Even light movement like walking or cycling strengthens the effects of IF on your metabolism. You don't need to start an intensive exercise routine — start small and build up.

Hunger is normal at first and usually disappears after one to two weeks. Drink enough water or tea, stay active and notice whether you feel real hunger or just habit. A supplement that supports your appetite can help to get through the first weeks more comfortably.
