7-Day Pescatarian Diet Plan

A pescatarian diet is perfect for people who may want to reduce their meat intake but aren’t quite ready to take the plunge into only eating plant-based foods. This healthy pescatarian diet plan includes a full week of seafood, eggs, dairy and vegetarian meals while avoiding meat and poultry. Eating more omega-3-rich seafood and plant-based meals offers a ton of health benefits, so increasing your intake is always a good idea. If you’re worried about overfishing and the sustainability of eating fish, check out our Clean Eating Buyer’s Guide to Seafood for more information.

What Is a Pescatarian Diet?

A pescatarian diet is a vegetarian diet that includes fish and other seafood. Most people who are pescatarians also eat eggs and dairy, so we included both in this plan. People following a pescatarian diet do not eat any meat or poultry.

Pescatarian Diet Benefits

If you’re wondering if the pescatarian diet is healthy, the answer is a resounding yes! People who eat more plant-based meals tend to eat more fiber because of the focus on fruits, vegetables, beans and lentils. Fiber has a ton of health benefits, like promoting a healthy gut and reducing the risk of heart disease and diabetes, and it helps maintain a healthy weight. Plus, the pescatarian diet includes fish, which means you can still get plenty of vitamin B12 and omega-3 fatty acids—nutrients that can be difficult to get enough of in a vegan diet.

Pescatarian Diet for Weight Loss

Is a pescatarian diet good for weight loss? It just might be. A 2022 review in the International Journal of Environmental Research and Public Health suggests that vegetarians tend to eat significantly fewer calories each day than their meat-eating counterparts. Plus, all the fiber in plant-based eating helps keep us full, which means we don’t feel as hungry in between meals.

To promote a healthy weight loss of 1 to 2 pounds a week, we set this plan at 1,200 calories a day and included modifications to bump up the calories to 1,500 or 2,000 calories a day, depending on your needs.
