A Turning Point in Nutrition Policy — And Why It Matters for South Africa

Earlier this month, the United States released the 2025–2030 Dietary Guidelines for Americans, marking one of the most significant shifts in public nutrition policy in decades. (The previous guidelines have been in place since 1977 and were based on mostly incorrect research findings by Dr Ancel Keys) While these guidelines are U.S.-based, their implications extend far beyond American borders — particularly for countries like South Africa, where rates of metabolic disease are rising rapidly and placing increasing strain on individuals, families, and our already overburdened healthcare systems.

For the first time, these guidelines explicitly acknowledge what many clinicians have observed for years: the majority of adults are metabolically unwell.

In the U.S., it is now estimated that over 90% of adults have some degree of metabolic dysfunction — including insulin resistance, prediabetes, obesity, type 2 diabetes, fatty liver disease, or related conditions. While South Africa lacks equally comprehensive national metabolic data, local prevalence rates of obesity, diabetes, hypertension, and cardiovascular disease suggest we are following a very similar trajectory.

This policy shift matters — not because it tells people what to eat — but because it reframes how we understand chronic disease.

From Willpower to Physiology: A Long-Overdue Reframe

For decades, nutrition advice has implicitly placed responsibility on individuals: eat less, move more, have more willpower.

Yet this simplistic narrative has failed to stem the tide of chronic disease. The new guidelines reflect a growing recognition that metabolic dysfunction is not a personal failure, but a predictable physiological response to:

• Highly processed, refined foods

• Excess added sugars and refined carbohydrates

• Inadequate protein intake

• Disrupted hunger and satiety signalling

• Chronic stress and poor sleep

• Sedentary lifestyles layered onto poor metabolic health

This reframing is particularly important in South Africa, where socioeconomic inequality, food insecurity, and limited access to preventative care compound metabolic risk at a community level.

What Has Actually Changed in the New Guidelines?

Several shifts stand out as especially relevant for both clinicians and communities:

1. A Return to Real, Whole Foods

The guidelines place renewed emphasis on minimally processed, nutrient-dense foods, including both animal and plant sources. This is a meaningful departure from decades of overly reductionist messaging that often demonised entire food groups without considering metabolic context.

For South Africans, this supports culturally familiar foods — meat, eggs, dairy, vegetables, legumes — rather than ultra-processed “health” products that are often expensive and metabolically harmful.

2. Protein Is Recognised as Foundational

Adequate protein intake is now clearly positioned as essential for:

• Metabolic health

• Blood sugar regulation

• Muscle mass and strength

• Satiety and appetite control

• Healthy ageing

This is particularly relevant in older adults, people with chronic disease, and those attempting weight loss — groups that are often under-eating protein while over-consuming refined carbohydrates.

3. A More Honest Conversation About Sugar and Refined Grains

The guidelines acknowledge the role of added sugars and refined carbohydrates in driving metabolic disease. This is critical in a country like South Africa, where sugary beverages, refined maize products, white bread, and processed snacks are widely consumed — often because they are affordable, accessible, and aggressively marketed.

At a population level, this calls for policy, education, and food-system reform, not just individual behaviour change.

4. Explicit Support for Therapeutic Low-Carbohydrate Approaches

For the first time, low-carbohydrate dietary approaches are explicitly supported for conditions such as:

• Obesity

• Type 2 diabetes

• Hypertension

• Fatty liver disease

This does not mean everyone should eat low-carb. Rather, it acknowledges that metabolic illnesses require metabolic solutions, and carbohydrate reduction is one evidence-based option among several.

This is an important step toward legitimising approaches already being used successfully by many South African clinicians, dietitians, and health coaches working in metabolic and lifestyle medicine.

Why This Matters for South African Healthcare

South Africa faces a dual burden of disease: infectious illnesses on one hand, and a high rate of non-communicable diseases on the other. Diabetes, hypertension, stroke, and cardiovascular disease now account for a significant proportion of morbidity, disability, and healthcare expenditure.

These conditions do not exist in isolation. They intersect with:

• Mental health disorders

• Chronic pain

• Inflammatory conditions

• Cognitive decline

• Reduced quality of life and productivity

Healthcare systems — both public and private — are largely structured around disease management, not metabolic prevention or reversal. This policy shift reinforces the need to integrate nutrition and metabolic health into mainstream care, rather than treating them as optional or alternative.

Beyond the Body: Metabolic Health and the Brain

One of the most promising implications of this shift lies beyond traditional physical health outcomes.

There is growing evidence that many mental health conditions — including bipolar disorder, schizophrenia, major depression, and cognitive disorders — have a significant neurometabolic component. The brain is one of the most metabolically demanding organs in the body, and disruptions in energy metabolism, insulin signalling, and inflammation can profoundly affect mood, cognition, and behaviour.

Emerging research into ketogenic and metabolic therapies suggests meaningful potential for certain individuals when these approaches are applied carefully, ethically, and with appropriate support.

For practitioners working at the intersection of neurology, mental health, and rehabilitation, this represents a powerful new frontier — one that requires education, collaboration, and thoughtful implementation.

Guidelines Don’t Change Lives — Implementation Does

Policy shifts are important, but guidelines alone do not improve health. People need:

• Clear, practical education

• Supportive environments

• Community accountability

• Individualised guidance

• Time and safety to change habits

This is where community-based programmes, group coaching programmes, and interdisciplinary care become essential. Translating evidence into daily life — especially in a context of stress, limited resources, and conflicting information — is often the missing link.

Building Metabolic Resilience for 2026 and Beyond

As we move into 2026, the conversation is shifting from short-term fixes to long-term metabolic resilience. This means:

• Moving away from chronic dieting

• Understanding how food affects energy, pain, mood, and cognition

• Rebuilding trust in the body’s signals

• Creating sustainable habits that support health across the lifespan

For those who want guidance in making these changes in a clear, structured, and supportive way, working with a practitioner who understands metabolic health can make all the difference. Sustainable improvement in conditions such as insulin resistance, chronic inflammation, fatigue, pain, and related metabolic illnesses requires more than information — it requires personalised support, education, and practical implementation over time.

Whether you are navigating metabolic challenges yourself, supporting a family member, or working within healthcare or community settings, this moment represents an opportunity to do things differently — and better.

If you are ready to move beyond trial-and-error and start addressing metabolic health at the root, I offer structured support to help you do exactly that.

Real change starts at the root.
