A volumetrics diet is based on eating more high-water volume foods. Foods with more water fill you up naturally and can therefore help you lose weight as you naturally eat fewer calories.
This premise is sound, as it leads to people eating more nutrient-dense foods like fruits and vegetables without increasing calorie intake.
The diet was developed by Barbara Rolls, PhD, a nutrition and obesity researcher at Penn State University.
This article will cover everything you need to know about following a volumetrics diet and give you a sample 7 day plan to follow that contains daily meals and a shopping list.

Foods to Eat on a Volumetrics Diet Plan
The bulk of the diet consists of low-calorie, high volume foods. Typically, these are foods that contain lots of water and fiber.
These kinds of foods have high satiety, meaning they keep you fuller for longer with fewer calories. Because of this, many studies find that eating more water and fiber help long-term weight loss.
For example, there are studies show that fiber can automatically reduce a person’s calorie intake, leading to weight loss (1, 2). Fiber may also promote the release of satiety hormones that help regulate how full you are (13).
Drinking water too has been shown to help with weight loss. For example, one study of middle-aged, overweight and obese people lose 44% more weight than the control when they drank water before a meal (3).#
Other studies have also found that drinking water can help boost your metabolism. One found a boost of 30% within 60-90 minutes of drinking water (4, 5).
Generally, the types of foods you should eat more of are as follows:
- Fresh fruits
- Fresh or frozen vegetables
- Beans and legumes
- Whole grains
- Fiber-rich cereals
- Low-fat fish
- Poultry
- Lean meats
- Minimal added sugars
- Water (rather than sugary drinks)
Following this general advice is the best way to go about the diet.
Volumetrics Diet Food Classification
The Volumetrics diet divides foods into four categories based on their calorie density.
| Category of Foods | Food Density | Example Foods |
|---|---|---|
| 1 | Lowest Food Density / Eat Most Of | fruits, non-starchy vegetables, nonfat milk, soups |
| 2 | Lower Food Density / Eat More Of | Whole grains, legumes, starch vegetables, low-fat meats |
| 3 | Higher Food Density / Eat Less Of | Meat, cheese, refined carbohydrates like white bread |
| 4 | Highest Food Density / Eat Fewest Of | Butter, crackers, oil, nuts (for oil and nuts, see below) |
Three meals a day, with one or two snacks, is a good rule of thumb to follow.
Problems with the Volumetrics Diet
Generally, the foods recommended within the volumetrics diet are good examples to follow. However, there are a few groups of foods that are discouraged within the diet that actually help promote weight loss in moderate amounts.
All these groups are included because they are higher in fats. However, these are important, healthy fats that have a wide variety of functions. It is important not to exclude them from your diet.
Limited Fatty Fish Included
Fatty fish are the biggest source of omega-3 fatty acids, which are important in heart and brain health health (6). It is a nutrient many people do not get enough of.
Various studies show that eating fatty fish can the risk of many health conditions like heart attacks and strokes (7, 8, 9). One large study of 40,000+ people found people who ate one or more servings of fish a week lowered their risk of heart disease by 15% (10).
Even in relation to weight loss, studies find fatty fish can help lower body fat and encourage weight loss (11, 12, 13). They are a good source of protein, which helps build muscle and increase calorie expenditure.
Fatty fish include:
- Salmon
- Herring
- Trout
- Mackerel
- Sardines
- Tuna
Nuts and Seeds are Discouraged
People think because nuts and seeds are high in fat, they encourage weight gain. However, many studies find the opposite.
An extensive study that examined 36 studies found common nut consumption wasn’t associated with increased weight, waist size, or BMI (14).
Another study found those who ate two or more portions of nuts per week had a 31% lower risk of weight gain compared to the control group that didn’t eat them (15).
There seem to be a few reasons nuts can help you cut body and therefore, belly fat. This is in part due to the fact that eating nuts has been shown to reduce feelings of hunger (16, 17).
Great nut and seed additions to your diet include:
- Almonds
- Pistachios
- Chia seeds
- Flax seeds
- Walnuts
- Peanuts
- Pecans
No Cooking with Olive Oil
Olive oil , especially extra virgin olive oil, is very healthy for you.
It contains high amounts of healthy monosaturated fats and antioxidants that may help reduce the risk of chronic diseases (18, 19).
Studies also find the main fatty acid in olive oil, oleic acid, helps reduce markers such as CRP, which show levels of inflammation within the body (20, 21).
Although eating lots of fat can lead to weight gain, one study of 30-months involving over 7,000 people found that consuming olive oil was not linked to weight gain. (22).
Is the Volumetrics Diet a Good Diet to Follow?
The 2022 U.S. News and World Report Best Diets ranks the Volumetrics Diet number 5 in Best Diets Overall and gives it an overall score of 3.7/5.0.
In terms of its scientific credentials, eating high-water foods generally leads to more consumption of healthy, nutritious foods like fruits and vegetables, which is obviously a good thing.
There are also glaring omissions that foods that are scientifically proven to offer health and weight benefits are omitted. In particular, these include foods such as nuts, seeds, fatty fish and olive oil.
However, you shouldn’t omit foods containing healthy fats simply because they may contain extra calories, particularly if studies show they help weight loss over time.
Therefore, following a volumetrics diet can be followed relatively healthy. With a few caveats, it can be an even better diet to follow.
Our diet plan actually resembles a volumetrics diet closely, but is based on the Mediterranean diet, a healthier alternative and the most recommended diet by a number of organisations, such as:
- Harvard Medical School
- Mayo Clinic
- American Heart Association
- Arthritis Foundation
- Osteoarthritis Foundation Internal
