A low-fat diet is an eating plan that reduces the amount of fat you consume, particularly saturated fats and trans fats, which are linked to high cholesterol and an increased risk of heart disease. The main goal is to promote better heart health, aid weight management, and support overall wellbeing.
What Does It Involve?
A low-fat diet typically involves:
- Reducing high-fat foods like fried items, processed meats, full-fat dairy, pastries, and snacks.
- Choosing lean proteins such as skinless chicken, turkey, fish, pulses, and low-fat dairy products.
- Incorporating more fruits, vegetables, whole grains, and legumes.
- Limiting oils and spreads, and opting for heart-healthy fats in small amounts (like olive oil or avocado).

Common Foods on a Low-Fat Diet
Is It Good for Fitness?
A low-fat diet can be helpful for people trying to:
- Reduce body fat as part of a weight loss plan
- Lower cholesterol and improve heart health
- Manage calorie intake while still fuelling workouts
However, it’s important not to cut out all fat. Your body still needs essential fats for hormone production, nutrient absorption, and energy – especially if you’re active or training regularly. The key is to reduce unhealthy fats and choose healthy fats in moderation.
Popular Types of Low-Fat Diets
1. The Ornish Diet
Developed by Dr. Dean Ornish, this is one of the most well-known low-fat diets. It focuses on:
- Very low fat intake – typically less than 10% of daily calories
- Whole plant-based foods – fruits, vegetables, whole grains, and legumes
- Minimal to no meat, dairy, or processed foods
- Regular physical activity and stress management practices like yoga or meditation
Ideal for: People aiming to improve heart health, lower cholesterol, or manage weight through lifestyle changes.
2. The DASH Diet
(Short for Dietary Approaches to Stop Hypertension)
While not extremely low in fat, DASH promotes lower fat intake, particularly saturated fats, and encourages:
- Plenty of fruits and vegetables
- Wholegrains, lean proteins, and low-fat dairy
- Low sodium and low sugar intake
Ideal for: Lowering blood pressure, supporting heart health, and offering a well-rounded diet for general fitness.
3. The Volumetrics Diet
This approach focuses on low-energy-density foods – foods that are filling but low in calories and fat.
It encourages:
- Lots of water-rich foods (soups, salads, fruit, vegetables)
- Reduced fat intake by avoiding fried and processed foods
- Smaller portions of lean meats and dairy
Ideal for: Sustainable weight loss and maintaining energy levels during fitness training.

Final Thoughts
A low-fat diet can support fitness and health goals when followed sensibly.
All of these diets aim to reduce unhealthy fats while promoting nutrient-rich foods to support fitness, energy levels, and long-term health.
The best results often come from combining it with regular exercise, portion control, and an overall balanced diet.
Before starting a new diet plan, especially one that involves significant changes, it’s best to speak to a healthcare professional or registered dietitian.
