# Nutrition and diets in uterine cancer
In uterine cancer, nutrition and body weight play a role, both in the development of the disease and in how the body copes with treatment and recovery. This tab describes which eating patterns and diets are being investigated in research and practice, and what is known about them so far.
Weight loss and weight management
ResearchediPositive results in clinical studies, not yet standard treatment
Overweight and obesity are strongly associated with the risk of uterine cancer. This is because overweight affects hormone balance and inflammatory processes in the body. During and after treatment, many clinicians focus on maintaining or gradually reducing body weight, not only to prevent recurrence, but also because the body is stronger for recovery.
Research from 2026 compares different approaches to weight management in patients with uterine cancer: lifestyle changes (nutrition and exercise), surgical interventions, and medications that affect appetite. These studies show that weight loss and maintenance through nutrition and lifestyle are central pillars of care. The goal is usually not drastic change, but a stable pattern that you can maintain.
Important: rapid weight loss shortly around your treatment can be burdensome for the body. The timing and speed of weight change belong in a conversation with your oncology team or dietitian.
Nutrition and insulin resistance

Insulin resistance — a condition in which body cells respond less well to the hormone insulin — appears to be a risk factor for uterine cancer. Eating patterns that help prevent insulin spikes are therefore being examined in research.
This is mainly about regular, balanced meals with sufficient fiber, proteins and healthy fats, and fewer rapidly absorbed carbohydrates. Foods such as whole grains, vegetables, nuts, fish and lean meat products can keep insulin levels more stable. Research from 2026 shows that nutrition and certain inflammatory markers in the blood are associated with the response to hormonal treatment. This suggests that nutrition matters not only for weight, but also for how your body handles medications.
However, this is still in the research phase; it is not a standard recommendation for all patients.
Mediterranean dietary pattern

The Mediterranean pattern (plenty of vegetables, fruit, whole grains, olives, fish, limited red meat) is generally investigated in cancer research as a protective pattern. Researchers are also interested in this pattern for uterine cancer, because it can lower inflammatory markers and help stabilize weight.
Specific research focused on uterine cancer and Mediterranean eating pattern is limited, but broader cancer research shows that this pattern, with regular consumption, can help improve body composition and reduce inflammation. This can be useful, both for prevention and during and after treatment.
The advantage of this pattern is that it has no strict rules and can be easily adapted to personal taste and cultural habits.
Protein-rich nutrition

Especially around surgery and recovery, adequate protein intake plays a role. Proteins are needed for wound healing and maintenance of muscle mass, which is especially important because many patients lose energy and appetite during and after treatment.
Research from 2026 on recovery after hysterectomy — the most common operation in uterine cancer — indicates that nutrition around the operation influences how quickly the gastrointestinal tract functions well again. Adequate protein helps the body recover. This can come from fish, meat, eggs, dairy, lentils, nuts and seeds.
However: quantities and timing belong with your own treatment plan. Hospitals and outpatient teams are increasingly providing guidance from a dietitian on this.
Nutrition and fatigue

Fatigue is a common side effect during and after uterine cancer treatment. Nutrition can indirectly contribute: stable energy intake throughout the day, not too much sugar, sufficient iron and B vitamins can help. However, this is tailored to the individual and not a universal solution.
Studies on quality of life and patient experiences in 2026 show that many patients have less energy and that nutrition can contribute to this — but usually a combination of small, regular meals, sufficient fluids and rest works better than one specific dietary pattern.
Other patterns: ketogenic, fasting, supplements
UnproveniNo scientific evidence that it works
Ketogenic diet (very low in carbohydrates, high in fat), intermittent fasting and various supplements are sometimes recommended for cancer treatment. For uterine cancer specifically, there is little evidence. Some studies investigate whether these approaches help, but strong recommendations do not exist.
Ketogenic diet can cause body weight to drop more quickly, but that is not necessarily useful shortly before or after surgery and chemotherapy. Fasting can conflict with efforts to build a good nutritional pattern around treatment.
Many supplements (vitamins, minerals, herbs) can interfere with medications, especially with hormonal therapies that are often used in uterine cancer. Discussing this with your doctor or dietitian is essential.
Summary: nutrition is tailored
Uterine cancer is linked to body weight and metabolism, so nutrition plays a role. Research suggests that stable weight, prevention of insulin spikes, adequate protein around treatment, and anti-inflammatory nutrition can be useful. The most studied pattern is a varied, largely plant-based approach with fish and moderate protein — similar to a Mediterranean dietary pattern.
However: nutritional choices in uterine cancer are heavily dependent on your treatment phase, side effects, taste and cultural background. This should be discussed with your oncologist, general practitioner and preferably a dietitian with experience in cancer patients. They can take your preferences and physical condition into account and develop a pattern that works for you.
