Why Carbohydrates Are Not the Enemy

Carbohydrates have been unfairly blamed for decades.

While some patients benefit from temporary carbohydrate reduction, long-term elimination is rarely sustainable and can undermine metabolic health. Chronic avoidance of carbohydrates may impair thyroid signaling, reduce training capacity, increase fatigue, and make muscle preservation more difficult.

Carbohydrates are not inherently fat-promoting.
Context matters.

Why Carbohydrates Became the Villain

Low-carbohydrate diets can produce short-term weight loss, particularly through glycogen depletion and reduced calorie intake. For some patients with significant insulin resistance, carbohydrate reduction can temporarily improve appetite control and glucose regulation.

However, extrapolating short-term success into a universal rule has caused problems.

Carbohydrates themselves do not cause obesity. Overconsumption in the wrong context, combined with insulin resistance and metabolic dysfunction, is the issue.

What Happens When Carbohydrates Are Eliminated Long Term

Prolonged, aggressive carbohydrate restriction can lead to:

Carbohydrates and Muscle Preservation

Carbohydrates play an important role in:

• Supporting resistance training performance

• Replenishing muscle glycogen

• Reducing muscle breakdown during calorie deficits

When carbohydrates are chronically too low, the body may rely more heavily on muscle tissue for energy, especially during training. This can worsen metabolic adaptation and increase long-term regain risk.

Carbohydrates and Hormonal Health

Adequate carbohydrate intake supports:

• Thyroid hormone function

• Cortisol regulation

• Leptin signaling

• Training recovery

In some patients, especially women and those with long dieting histories, overly restrictive carbohydrate intake can worsen hormonal dysregulation rather than improve it.

Why “Carbs Are Bad” Oversimplifies Obesity

Obesity is not caused by a single macronutrient.

Patients can gain weight on:

• High-carbohydrate diets

• Low-carbohydrate diets

• High-fat diets

• “Clean” diets

What matters most is how the body processes energy, how hunger and satiety are regulated, and how sustainable the approach is over time.

Carbohydrates are one variable in a complex system, not the enemy.

How OVH Personalizes Carbohydrate Intake

At Optima Vida Healthcare (OVH), carbohydrate recommendations are individualized, not ideological.

We adjust carbohydrate intake based on:

• Insulin sensitivity and metabolic markers

• Activity level and training demands

• Treatment phase (active loss vs maintenance)

• Medication use and appetite regulation

• Digestive tolerance and energy levels

For some patients, lower carbohydrate intake is appropriate early on. For many others, strategic reintroductionimproves energy, exercise performance, mood, and metabolic stability.

Reintroducing Carbohydrates Can Improve Progress

Many patients fear that adding carbohydrates back will “undo everything.”

In reality, appropriate carbohydrate reintroduction often leads to:

• Better training consistency

• Improved muscle preservation

• Reduced fatigue

• Improved thyroid and metabolic signaling

• Greater long-term adherence

Weight stability or slower loss during this phase does not indicate failure. It often reflects a healthier metabolic state.

Carbohydrates Are a Tool, Not a Threat

Carbohydrates can support:

• Physical performance

• Metabolic health

• Hormonal balance

• Long-term sustainability

They can also worsen outcomes when used without regard to insulin resistance, portion size, or overall context.

The answer is not fear.
The answer is precision.

The OVH Perspective

Fear is not a nutrition strategy.

At OVH, carbohydrates are neither universally restricted nor universally encouraged. They are used intentionally, in amounts and contexts that support metabolic health, muscle preservation, and long-term success.

Obesity care works best when nutrition supports the body instead of fighting it.
