Dr. Daniel D. Beninati's Approach

The objectives of Dr. Beninati’s medical practice are to help both men and women feel their best and remain healthy throughout various stages of life.
He integrates conventional medicine and clinical nutrition with alternative and complementary medicine. To achieve optimal nutrition Dr. Beninati utilizes a diet plan that is appropriate for each individualized patient based on their biochemical uniqueness and metabolic needs. Such as : Vegan, Ketogenic, Intermittent Fasting, Mediterranean or Paleo diet.
He combines conventional lab tests with functional medicine ones such as: metabolic biomarkers in blood and urine, food sensitivity, comprehensive digestive stool analysis and microbiology , genomic test of DNA single nucleotide polymorphism, adrenocortex stress profile, bone resorption assessment, estrogen metabolism assessment and many other ones.
His approach is science based and is achieved by implementing the principles of functional medicine that addresses the underlying cause of the condition instead of treating only a particular symptom. He believes in engaging his patients in a effective and productive partnership that empowers them to take better care of themselves.

Optimize their nutrition, according to their individual needs:
Vegan, Ketogenic, Intermittent Fasting, Mediterranean or Paleo diet.
Achieve and maintain their optimal weight
Take individualized optimal supplementation
Use proper herbal supplementation if indicated
Balance all hormones if necessary
Adopt an adequate exercise program
Achieve an effective anti-stress modality when applicable


Bio-Identical Hormone Replacement Therapy is a common term for the treatment of conditions caused by the effects of hormone deficiencies resulting from menopause. BHRT uses hormones that are identical in their molecular structure to the hormones produced naturally within the human body.

BHRT is also used more generally to describe the practice of using only Bio-Identical hormones in the treatment of all hormone deficiencies, not just menopause. These include perimenopause, which is the time of change leading into menopause, and andropause in men.

Hormones regulate the activity of cells and tissues in the body. Optimized and balanced hormones are essential to good health and a feeling of well-being. In both men and women, hormones decrease with age causing a wide range of symptoms such as fatigue, weight gain, loss of sex drive depression and disrupted sleep patterns (insomnia). The hormones estrogen, testosterone, progesterone, thyroid and cortisol all play a very serious role in daily life and health and an imbalance can impact life dramatically.

Many people resign themselves to living with the serious symptoms caused by hormone imbalance, accepting them as an unchangeable and an untreatable part of the aging process. However, maintaining optimum levels of hormones promotes an improved quality of life and prevents many of the degenerative illnesses commonly associated with aging.

Dr. Beninati has been prescribing Bio-Identical Hormones for more than 10 years. He also stays up to date with the most current and fast evolving literature and periodically attends conferences concerning these issues. He is a member of the “Bio-Identical Hormone Society” and the “Andropause Society”.

You can make an appointment with Dr Beninati to discuss your concerns about the safety and benefits of Bioidentical Hormone Replacement Therapy; he will provide you with all the current information and answer all pertinent questions that you may have, so you can make an informed and sound decision whether BHRT is appropriate for you.

Genomics Testing

Genetics is rarely all or nothing. In almost every case, the genes you receive from your parents may give you an increased or decreased chance of a particular outcome. The simplest of these outcomes include sex, eye color and hair color. The more complex outcomes include body function including: digestion, detoxification, blood sugar regulation, mitochondrial function, free radical production, premature aging, master antioxidant production and much more. Just because you have certain gene, the outcome is not 100% certain since that particular gene has to be expressed or not. External factors come into play such as lifestyle choices: diet, exercise, sleep, stress, etc. as well as exposure to environmental factors. Epigenetics is the science that studies how those external factors can expressed or suppressed a particular gene. Learning about your genome can help you uncover secrets that your DNA holds about your health and proactively offer genetic nutritional support. Discovering your unique genome may help you take a preventive approach to your overall wellness or improve your health. This information is essential in the practice of Functional Medicine and can be used in the clinical decision-making process to better help you in the search for optimal health. Personalized medicine is the future of healthcare and genomic testing is becoming an integral part of this. As unique individuals, we all have genetic differences, making the one-size -fits-all model of health care a thing of the past. Genetic testing allows the opportunity to look at your genes, which serve as the blueprint for your health. Taking this a step further, the study of epigenetics looks at your diet, lifestyle, and the environment in which you live, which impact how your genes express themselves. Genetic testing helps identify your genetic variant, or gaps in your DNA, which may impact your health. Looking at these variants can give us an incredible amount of information about how you process nutrients, detoxify chemicals, utilize iron, balance your gut bacteria, neutralize free radicals, as well as understand your brain’s neurotransmitter function and much more. By understanding these genetics variants, which can potentially cause imbalances, our goal is to supply the right nutrients and target supplementation to the body to support that faulty function. There are many reasons why someone may want to look at their genetic makeup. Some major reasons include people’s curiosity about their ancestry and the desire to learn their risk of potential health condition or their genetic susceptibility. A top reason for many people is that they want answers to why their labs test come back “normal” yet they still feel tired, irritable, depressed, wired or continue to struggle with things like digestive issues and cannot determine the reason for these chronic issues. Genetic testing can give some insight into why someone could be experiencing these issues, and what they can do about it. Genetic interpretation with Functional Genomic Analysis report can help us learn a lot about why we may not feel our best, as well as provide a step-by-step, personalized approach to address each area of concern based on an individual’s genetic makeup. We are pleased to announce we are now using Functional Genomic Analysis to analyze thousands of DNA variants and through their complex software we incorporate signs and symptoms questionnaire and Organic acid Testing pertaining to your case. The Genomic Resource Saliva Test Kit is for the exclusive use with the Functional Genomic Analysis software program. It is private, practical and personalized but doesn’t provide ancestry data or other information. Please call for more information.

Optimal Nutrition for a particular individual is the appropriate diet that applies to his or her condition and is based on their genetic and biochemical individuality. That could be the Vegan diet, Paleo diet, Mediterranean diet, Intermittent Fasting diet or Ketogenic diet.

Vegan Diet / Paleo Diet

For some people with severe cardiovascular disease a strict Vegan Diet or a modified Paleo Diet are indicated.

Ketogenic Diet / Paleo Diet

For other people suffering from prediabetes or metabolic syndrome, diabetes or PCOs a Ketogenic diet or Paleo diet are indicated.

Intermittent Fasting Diet /Ketogenic Diet

For an individual with a serious weight gain problem the Ketogenic Diet or the Intermittent Fasting Diet are very efficient for significant weight loss.

Paleo Diet / Ketogenic Diet

People suffering from Alzheimer or Parkinson’s a Paleo diet or Ketogenic Diet can be beneficial.

Paleo Diet

For individuals who are suffering from an autoimmune disorder such as: multiple sclerosis, Hashimotos thyroiditis, rheumatoid arthritis or inflammatory bowel disease, to mention some, a strict Paleo Diet is one of the major pillars to correct the “leaky gut”, quench inflammation and support a healthy immune system function.

These general guidelines are not intended to treat any condition without all necessary medical information that applies to your case. Please do not hesitate in making an appointment to see which diet plan is appropriate for you.

Our Weight Loss Program is based on:

The ketogenic diet to target body fat loss
Optimal nutrition
Elimination diet
Basically the diet is limited in carbs and good fats and moderate in proteins. It provides minimal carbs for a successful "fat burning" with enough proteins and fats that will prevent muscle loss. It is not like other extreme caloric restricted programs that are not generally healthy and promote inevitable muscle loss.
This Weight Loss Program is designed with your biochemical individuality in mind. We will order and interpret pertinent lab work accordingly to your metabolic risk factors that can be a major impediment for weigh loss.
By eliminating the most common intolerant foods that can be a contributing factor for weight loss, you will be able to achieve your optimal goal weight.
We use the state of the art inBody Bio-Impedance Machine that accurately measures not only your BMI (body mass index) but the percentage of body fat, visceral fat, lean mass and your Basic Metabolic Rate.
The diet by itself is very simple and has no secret supplement or "magic bullet". What makes this Weight Loss Program so successful is: the weekly visit, the professional supervision and counseling, the teaching of optimal nutrition and healthy eating habits and the monetary commitment up front that encourages patient's compliance, as already have been demonstrated by numerous studies.
This Weight Loss Program consist of 3 phases :
Weight loss phase
Transitional phase
Maintenance phase

At the completion of our Weight Loss Program you will found out which are the factors that makes you gain weight. These contributing factors could be:

A metabolic disorder
A particular food intolerance
A micronutrient deficiency
A hormone imbalance
