The Max Planck Diet is a two-week decrease diet. A severe weekly calendar dictates what you are allowed to eat. The food choice is very protein-heavy, fat and carbohydrates are greatly reduced. A weight loss of 9 kilos is promised within the 14 slimming days. You can find out here whether the Max Planck Diet keeps its promises.

What Is The Max Planck Diet?

Planck Diet

The Max Planck Diet is based on a strict weekly plan with precisely defined meals. These contain mainly meat, ham and eggs – in total, around 35 per cent of the daily energy intake comes from protein. Also, black coffee and tea are a key part of the seven-day plan, which is repeated later the first week.

The Max Planck Diet is 1 of the metabolic diets. Your goal is to increase your metabolism through nutrition planning. According to the diet description, metabolic performance should remain elevated for up to three years after the diet.

Max Planck Society And Max Planck Diet

The Max Planck Society – a recognized research organization – has nothing to do with this diet, despite having the same name. On the contrary: She distances herself from this concept. Who invented the Max Planck Diet is unknown.

This Is How The Max Planck Diet Works

Eating is done according to a strict plan – no more than two or three times a day. There is no room for quantity or interpretation when it comes to dishes. Overall, the amount of calories is limited to about 400 to 800 kilocalories per day.

The food of the Max Planck Diet consists mainly of steaks, boiled ham and boiled eggs. Vegetables, salad or fruit are on the daily menu and can be eaten in any quantity, but the choice is limited (e.g. spinach, lettuce, celery, tomatoes).

For breakfast, there is black coffee or tea with lemon. One round is also allowed in four days. On one day a week, you can eat as much natural yoghurt with fruit as you like in the evening – otherwise, no dairy products are allowed. Alcohol is strictly forbidden.

That Brings The Max Planck Diet

The Max Planck Diet leads to rapid weight loss. However, this is due to the initial water loss from increased kidney function (due to high protein consumption) and the drastically reduced calorie count. It, therefore, usually does not take long to return to eating normally once the diet has ended.

Up to nine kilos of weight loss in fourteen days are promised. There is no scientific evidence for this and for the (long-term) effectiveness of this type of nutrition.

Risks Of The Max Planck Diet

  • The yo-yo effect, like a balanced diet, cannot be learned
  • to be hungry
  • digestive problems
  • Lack of essential fatty acids, minerals and fibre
  • Health risks such as kidney failure or arthritis (with prolonged dieting)

Max Planck Diet: Conclusion

This diet is extremely one-sided. Long-term damage to health is unlikely due to the short duration of two weeks. However, an adequate supply of all the necessary nutrients is not guaranteed, which is why this type of nutrition is to be classified as questionable.

The promised weight loss of nine kilos is just as unrealistic as a change in metabolism. You don’t learn to eat a balanced diet and change your exercise habits. The Max Planck Diet is therefore not suitable for permanently reducing body weight.
