What is Diet Therapy?

Diet therapy is a physiologically based method of following a doctor’s meal recommendations in order to enhance one’s health and wellbeing. It employs customized dietary regimens to:

  • Treat or prevent a particular illness (such as cancer, cardiovascular diseases)
  • Promote wellness generally.
  • Cleanse the body (ie, neutralize or eliminate toxins from the body)

Include meals that improve specific health issues while avoiding items that could make the condition worse when taking medications. Certain medical disorders necessitate transiently beneficial dietary patterns. Dietitians frequently describe beneficial dietary habits. The eating regimen may change over time depending on how the person reacts and how their health status changes.

Types of Diet Therapies

  1. Ornish Diet

This very low-fat vegetarian diet attempts to aid in the reversal of arterial blockages that result in coronary artery disease and may aid in the prevention or slowing of the spread of prostate and other malignancies. It emphasizes plant-based foods and discourages the use of animal protein, processed carbs, and fat. The Ornish diet is efficient and economical when used as a part of an intensive lifestyle program for patients with symptomatic coronary artery disease. What advantages the diet’s specific food limits have, meanwhile, is unclear. Other diets that restrict refined carbohydrates and less healthy fats but do not restrict healthier fats may provide similar results (eg, olive oil).

  1. Macrobiotic Diet

The primary components of this diet include fruits, vegetables, whole grains, and cereals. However, there is little evidence to support the efficacy of a macrobiotic diet for treating cancer, despite some proponents’ claims that it can prevent and treat cancer as well as other chronic conditions. Without concrete proof of effectiveness, the macrobiotic diet has also been studied in patients with metabolic syndrome, prediabetes, and diabetes.

Other than its lack of effectiveness in disease prevention or treatment, this diet poses very few risks.

  1. Paleo Diet

This diet consists of foods purportedly eaten during the Paleolithic era, when sustenance was obtained by hunting or gathering (ie, animals and wild plants). Thus, the diet calls for:

  • Increasing protein intake.
  • Reducing carbohydrate intake.
  • Increasing fat intake, which should range from moderate to high (with intake mainly of monounsaturated and polyunsaturated fats).

Foods (such as dairy products, cereals, legumes, processed oils, refined sugar, salt, and caffeine) that are assumed to have been unavailable during the Paleolithic era are avoided. Some argue that many of these foods are beyond the capacity of human metabolism.

Numerous chronic degenerative conditions, including metabolic syndrome, type 2 diabetes, and coronary artery disease, are thought to be treated or reduced by the paleo diet. The paleo diet may also promote weight loss, boost athletic performance, improve sleep quality, and enhance cerebral function. However, there is little proof of this diet’s effectiveness.

A risk factor is poor nutrition (due to decreased intake of whole grains and dairy). Although little is known about the food of the Paleolithic era, some evidence shows that it was not as restricted as the present paleo diet.

The other types of diet therapies are as follows:

  1. A gluten-free diet is an example of a dietary modification you should maintain to stay healthy. To prevent damage to their digestive systems, people with a gluten narrow-mindedness must keep a strategic distance from foods that contain gluten.
  2. The diabetic diet is a very simple corrective diet that limits high-sugar items to regulate blood sugar levels.

Other effective diets for losing weight restrict foods like salt to manage blood pressure or soaking fat to manage cholesterol. These weight-control strategies require some getting used to. Your physician will work with you to emphasize the significance of.

Many diets are recognized and even advocated in both conventional and integrative medicine, such as the Mediterranean diet. There have been other additional diets recommended as means to improve health, with varying degrees of supporting data. They frequently offer similar advice (eg, limiting less healthful fats and refined carbohydrates, substituting with plant-based and whole foods).

When you fast intermittently, your body switches from using liver-produced glucose to fat-stored ketones (1). In animal experiments, it has been demonstrated to have positive metabolic effects (such as enhanced insulin sensitivity and autophagy, perhaps prolonged life span). Human studies haven’t provided as strong of a case for the health advantages.

Diet therapy effects might develop gradually and are notoriously challenging to examine, but here are some basic principles of diet therapy:

  • Side effect control: Your doctor may advise you to consume fewer calories before considering diet therapy, doctor-recommended drugs, or surgery if your illness was caused by a poor eating regimen. When the diet is in check, certain disorders, like cardiac diseases, can be managed more effectively. Even though you haven’t yet been given a heart disease diagnosis, your doctor may nevertheless advise you to cut back on your calorie intake since he observes that you have heart disease warning signs.
  • Consume fewer carbs Modification: When you engage in poor dietary habits like choosing oily foods, consuming an excessive amount of sweats, or avoiding vegetables, you put yourself at risk for serious medical problems. Your physician may suggest a modified eating plan after examining your diet and the hazards connected to it. It is crucial that you follow any prescription and regimen you receive from your doctor exactly as you would a professional medication. Your health can be significantly affected by little, simple changes you make to your food habits.
  • Organ Rest: If you are having surgery or your doctor is trying to control a medical condition, they may ask you to stop your food therapy in order to provide them a clearer picture of your health difficulties or to make the procedure go more smoothly. Some doctors may advise you to follow a liquid diet or a cautious eating pattern so that your digestive system can rest weak organs. Try to eat light foods as a result.
