Dieting has become a pervasive fixture in modern culture, representing a massive $76 billion industry in the United States alone. Millions embark on diets annually, often spurred by post-holiday overindulgence. However, the long-term success rate is discouragingly low, with only a small fraction maintaining their weight loss. This article delves into the history, principles, and modern interpretations of the Banting diet, a low-carbohydrate approach to weight loss with roots stretching back to the 19th century.
The Origins of Diet Culture
The concept of dieting is not new. Throughout history, individuals have sought various methods to manage their weight. From Lord Byron's vinegar-drenched potato diet to more extreme measures like tapeworm infections, the pursuit of an ideal physique has driven people to diverse and sometimes dangerous practices. Michael Pollan suggests that the modern "binge-and-diet" cycle stems from food marketing and an unstable food culture, contrasting it with the healthier, pleasure-focused eating habits of the French.
William Banting: The Pioneer of Low-Carb
Before the Atkins diet gained prominence, there was the Banting diet, named after William Banting (1796-1878), a London undertaker. Banting, hailing from a family of funeral directors to the Royal Household, struggled with obesity despite leading an active life. Frustrated with ineffective remedies like increased exercise, starvation diets, and medicinal spas, Banting consulted Dr. William Harvey.
Dr. Harvey, influenced by the dietary theories of Claude Bernard, prescribed a diet that restricted "bread, butter, milk, sugar, beer, and potatoes." Banting's new diet consisted of:
- Breakfast: 4-5 ounces of beef with a small biscuit or dry toast.
- Dinner: 4-5 ounces of fish with vegetables, accompanied by 2-3 glasses of claret, sherry, or Madeira.
- Tea time: 2-3 ounces of fruit with a rusk or two and unsweetened black tea.
- Supper: The same amount of meat or fish with another glass of claret or a tumbler of grog.
Banting experienced remarkable results, losing weight and improving his overall health. He documented his journey in "Letter on Corpulence, Addressed to the Public" (1863), which became a widely popular pamphlet. The success of Banting's diet led to the term "banting" becoming synonymous with low-carbohydrate dieting.

The Banting Diet: Core Principles
The Banting diet revolves around reducing carbohydrate intake while increasing the consumption of fats and moderate amounts of protein. This approach aims to shift the body's primary fuel source from carbohydrates to fat, promoting weight loss and potentially offering other health benefits.
Key Tenets of Banting:
- Low Carbohydrate Intake: Limiting or avoiding foods high in carbohydrates, such as bread, pasta, rice, potatoes, and sugary items.
- Emphasis on Healthy Fats: Incorporating sources like avocados, nuts, seeds, olive oil, and fatty fish.
- Moderate Protein Consumption: Including protein-rich foods like meat, poultry, fish, eggs, and dairy products in moderation.
- Whole, Unprocessed Foods: Prioritizing real foods in their natural state, minimizing processed items, additives, and artificial ingredients.
Modern Interpretations: Banting 2.0 and Tim Noakes
The Banting diet has seen a resurgence in popularity, with adaptations and modern interpretations emerging. One notable figure in this revival is Professor Tim Noakes, a South African scientist who has championed the Banting diet through his book "The Real Meal Revolution."
Tim Noakes' Banting Diet (Real Meal Revolution):
Noakes' version of the Banting diet is structured into four phases:
- Phase 1: Observation: A week of tracking your current diet to understand your body's responses to different foods.
- Phase 2: Restoration: A 2-12 week phase focused on restoring gut health and acclimating to the Banting way of eating, emphasizing foods from the green and orange lists while avoiding those from the red and light red lists.
- Phase 3: Transformation: Aiming for ketosis by strictly adhering to the green list foods, this phase continues until the desired weight loss is achieved, coupled with lifestyle modifications like exercise and intermittent fasting.
- Phase 4: Preservation: A flexible maintenance phase that allows the reintroduction of some foods, such as those from the orange list, while maintaining a personalized eating plan to sustain weight loss.
Food Lists: Green, Orange, and Red
The modern Banting diet often utilizes food lists to guide dieters in their choices:
- Green List: Foods to eat without restriction, including vegetables (leafy greens, cruciferous vegetables, onions, mushrooms), fruits (lemons, limes, tomatoes, olives), meat, fish, poultry, eggs, cheese, fermented foods (kefir, kimchi, sauerkraut), fats (avocado, butter, ghee, cream), and caffeine-free drinks.
- Orange List: Foods to eat in moderation, including nuts, dairy (milk, yogurt, sour cream), fruits (apples, bananas, berries, oranges), vegetables (beetroot, squash, sweetcorn, carrots, potatoes), legumes, pulses, fermented foods (kombucha), and caffeinated drinks.
- Red List: Foods to avoid, including fast food, sugary foods and condiments, sweets, gluten-containing grains, grain-based foods, processed dairy, processed fats, processed meats, and sugary drinks.
Potential Benefits of the Banting Diet
Proponents of the Banting diet suggest several potential benefits:

- Weight Loss: By shifting the body's primary fuel source to fat, the diet may promote weight loss and improve body mass index (BMI).
- Improved Energy Levels: Fat burning may preserve muscle energy, potentially enhancing exercise performance and endurance.
- Better Blood Sugar Control: Reduced fasting insulin levels may help lower the risk of type 2 diabetes.
- Reduced Risk of Heart Disease: Lower levels of triglycerides and cholesterol in the bloodstream may have a beneficial effect on blood pressure.
- Improved Appetite Control: Reduced levels of triglycerides may positively affect the hormone leptin, improving hunger signals.
- Improved Sleep: Weight loss or the promotion of adenosine, a brain chemical that helps regulate sleep, may indirectly improve sleep quality.
Potential Risks and Considerations
While the Banting diet may offer benefits for some individuals, it's important to consider potential risks and drawbacks:
- Nutrient Deficiencies: Restricting certain food groups may lead to nutrient deficiencies if the diet is not carefully planned.
- Long-Term Sustainability: The long-term safety and effectiveness of the Banting diet require further research.
- Impact on Bone Health: Extended use of low-carbohydrate diets may potentially increase calcium loss, impacting bone health.
- Compliance Challenges: Restricting food groups can make compliance difficult, especially for vegetarians or vegans.
- Contradiction with Established Dietary Guidelines: The Banting diet contradicts conventional dietary guidelines that emphasize whole grains, legumes, and certain fruits, which have proven benefits for reducing the risk of chronic diseases.
Who Should Avoid the Banting Diet?
It's advisable to consult with a healthcare professional before starting any new dietary regime, especially if you are:
- Under 18 years old
- Elderly
- Have a pre-existing medical condition
- Taking medication
The BRAT Diet: A Related, but Different, Approach
It's important to distinguish the Banting diet from the BRAT diet, which is a completely different dietary approach. The BRAT diet (Bananas, Rice, Applesauce, Toast) is a bland diet traditionally recommended for children experiencing diarrhea or other stomach problems. While the BRAT diet may be helpful for short-term symptom relief, it is not a sustainable or nutritionally complete diet for long-term use. Healthcare professionals now generally recommend a more varied bland diet over the BRAT diet.
Bland Diet Foods:
- Crackers
- Cooked cereals (oatmeal, cream of wheat)
- Herbal or decaffeinated tea
- Broth
- Electrolyte drinks
- Boiled or baked potatoes
Foods to Avoid on a Bland Diet:
- Milk and dairy products
- Fried, greasy, fatty, or spicy foods
- Proteins (steak, pork, salmon, sardines)
- Raw vegetables (salad greens, carrot sticks, broccoli, cauliflower)
- Acidic fruits (berries, grapes, oranges, lemons, limes)
- Alcohol, coffee, or other caffeinated drinks
