Crash and fat diets based on unbalanced nutrition, for example, are not just unlikely to bring long-term success – they also put additional strain on your digestive system and can cause constipation.
The globally best-known version of the low-carb principle is the Atkins diet. It involves four phases: in the first phase, carbohydrate intake is drastically reduced and the body primarily receives energy from fats and proteins. Although larger amounts of fruit and vegetables are recommended in later phases, the sudden change to a meat-heavy diet with a low quantity of carbohydrates can still lead to constipation.
Even if your body is very flexible, it needs a certain amount of time to adapt to each change. Just as unfamiliar eating times and ingredients or spices on holiday can cause digestion problems, so too can sudden major nutritional changes within the context of a diet.
If you want to change how you eat, you should do so in small steps over a long period of time. That way, your body can get used to the new form of nutrition gradually and won’t react with constipation.1
