A flexitarian diet is a diet that prioritizes plant-based foods like whole grains, fruits, and vegetables and limits the consumption of animal protein like eggs, red meat, fish, and chicken.
A flexitarian diet is typically adopted by people who want to decrease their meat consumption or those who are wanting to become vegetarian but are finding it difficult.
This type of plant-based diet can help prevent certain illnesses, such as high blood pressure, obesity, diabetes, and cancer. It is also benefits the environment by cutting down on water use and gas emissions.

Health benefits
A flexitarian diet has many health benefits, including:
- Preventing cardiovascular disease: increased consumption of fruits and vegetables helps to combat free radicals and improve arterial health, preventing cardiovascular diseases such as high blood pressure, atherosclerosis, and heart attack;
- Supporting weight loss: eating more fiber-rich foods, such as whole grains, fruit, and vegetables, helps increase satiety and decrease hunger throughout the day;
- Lowering cancer risk: foods rich in vitamins and antioxidants help protect healthy cells from damage caused by free radicals;
- Avoiding diabetes: the dietary fiber found in whole grains, fruits, and vegetables helps to control blood sugar levels by slowing down the absorption of sugar in the body.
A flexitarian diet can also help preserve the environment by cutting down on gas emissions, logging, and water use.

According to registered dietitian Dawn Jackson Blatner, a flexitarian diet should start by increasing your consumption of fruits and vegetables. In addition, it is important to cut back on animal protein, such as eggs, red meat, chicken and fish.
A flexitarian diet consists of three phases:
- Initial phase: in this phase, the recommendation is to cut out meat on two days of the week. Meat consumption during the remaining five days should not exceed 790 grams total;
- Advanced phase: in the advanced phase, it is recommended to avoid meat 3-4 days a week and to consume only 510 grams total during the rest of the week;
- Expert phase: the recommendation is to avoid meat 5 days a week and consume only 255 grams total the other two days.
It is important to remember that there is still no exact definition of a flexitarian diet. For example, a flexitarian diet could mean avoiding meat one day a week, decreasing the amount of animal protein in each meal, or eating meat only once a week.
It is important to talk to a registered dietitian before starting a flexitarian diet. They can help you develop an individualized diet plan that meets your specific goals and nutritional needs.
