HCG-diet-icaroSobre o HCG:

Quando seu uso do HCG objetiva #emagrecimento saudável, sugiro considerar:

0 – Se contra fatos não há argumentos, SOBRAM evidências de que o bom uso do HCG ajuda muitos a perder peso de forma saudável e sem dependências.
1 – Muita gente opinando por aí, infelizmente, sem conhecer direito o método ou seus fundamentos
2 – Muita gente preconceituosa manifestando-se mas que, mesmo já sabendo da quantidade de evidências científicas e práticas, parece que agora simplesmente “não quer dar o braço a torcer”
3 – TUDO na vida pode ter bom ou mal uso e isto não faz de algo-em-si bom ou ruim mas sim do uso que se faz, adequado ou não
4 – Quem tem o poder de influenciar os demais, deveria ter muito critério em fazer isto no Bem, com o devido embasamento e procurando falar a verdade, que tenha efetivamente buscado conhecer melhor, direito
5 – O uso adequado do HCG é habitualmente MUITO mais seguro que o uso de vários tarja-preta e demais medicamentos para emagrecimento vendidos, prescritos e utilizados abusivamente por aí MAS o HCG não é fabricado no Brasil… Por hora, só é manipulado ou importado. Entendem “a questão”?
6 – BONS profissionais de saúde só indicam o HCG para paciente com bons hábitos de vida (ou no sincero caminho de melhoria destes) e mínimo equilíbrio hormonal geral, sob acompanhamento rigoroso e idealmente multidisciplinar do paciente – tudo isto é fundamental para o sucesso e segurança do método.

Estudo recente comprova, sobre a eficácia do uso racional do HCG como adjuvante na perda saudável de peso (e redução de risco cardiovascular):

Pontos-chave abordados sobre o HCG:

–       Funciona bem associado a BONS HÁBITOS DE VIDA, dieta hipocalórica (bem orientada) e suplementação adequada (por exemplo de vitaminas, minerais e probióticos);

–       O uso do HCG aumenta/otimiza o uso das reservas de gordura viscerais (justamente as mais perigosas para a saúde e que a grande maioria dos métodos de emagrecimento “convencionais” e até mesmo químicos tem dificuldade de abordar eficazmente, com a devida prioridade)

–       As doses utilizadas do HCG para os fins citados são bem pequenas quando comparadas às quantidades de HCG circulantes em uma gestação

–        O uso racional do HCG, junto a bons hábitos de vida pode ser EFICAZ tanto na redução da massa gordurosa quanto dos fatores de risco associados a doenças cardiovasculares

–       O uso do HCG pode ajudar a melhorar o perfil lipídico geral do paciente (colesteróis e triglicerídeos)

–       O HCG em si causa maior perda de massa gorda por quem o utiliza, além de redução na fome/apetite – ou seja, não é só a dieta hipocalórica quem emagrece o paciente que usa o HCG, como erroneamente muitos pensam por aí (quem só faz dieta hipocalórica tende a ter grande perda de massa muscular associada, o que não costuma ocorrer em quem faz uso racional e bem orientado do HCG)

ABSTRACT

Being overweight or obese is associated with an increased risk for the development of non-insulin-dependent diabetes mellitus, hypertension, and cardiovascular disease. Dyslipidemia of obesity is characterized by elevated fasting triglycerides and decreased high-density lipoprotein-cholesterol concentrations. Endothelial damage and dysfunction is considered to be a major underlying mechanism for the elevated cardiovascular risk associated with increased adiposity. Alterations in endothelial cells and stem/endothelial progenitor cell function associated with overweight and obesity predispose to atherosclerosis and thrombosis.

In our study, we analyzed the effect of a low calorie diet in combination with oral supplementation by vitamins, minerals, probiotics and human chorionic gonadotropin (hCG, 125-180 IUs) on the body composition, lipid profile and CD34-positive cells in circulation.

During this dieting program, the following parameters were assessed weekly for all participants: fat free mass, body fat, BMI, extracellular/intracellular water, total body water and basal metabolic rate. For part of participants blood chemistry parameters and circulating CD34-positive cells were determined before and after dieting.

The data indicated that the treatments not only reduced body fat mass and total mass but also improved the lipid profile. The changes in body composition correlated with the level of lipoproteins responsible for the increased cardiovascular risk factors. These changes in body composition and lipid profile parameters coincided with the improvement of circulatory progenitor cell numbers.

As the result of our study, we concluded that the improvement of body composition affects the number of stem/progenitor cells in circulation.

Keywords: weight reduction, body composition, cardiovascular risk factors, lipid profile, progenitor cells.

INTRODUCTION

Living in an environment characterized by calorie-rich foods and low physical activity, over two thirds of Americans are overweight 1. This is a major public health problem, as obesity predisposes to a variety of age-related inflammatory diseases, including insulin resistance, type 2 diabetes, atherosclerosis and its complications, fatty liver diseases, osteoarthritis, rheumatoid arthritis, and cancer 2-4. Clinical studies have identified a relationship between increased body weight and cardiovascular disease including coronary atherosclerosis, congestive heart failure, arrhythmias, and stroke 5-11.

In addition to established cardiovascular risk factors, systemic inflammation, increased oxidative stress, and altered hemodynamics associated with excess weight may directly contribute to endothelial injury and dysfunction 12. Progenitor cells, which are released from the bone marrow are sensitive to oxidative stress 13-16. Circulating endothelial progenitor cell (EPC) numbers have been found to be lower in obese subjects compared to overweight or normal weight adults, and the colony-forming capacity of these cells is blunted 17, 18. Alterations in endothelial cells and EPC function associated with obesity precede atherosclerosis and thrombosis 19-21. Moreover, EPCs expanded from the obese subjects possessed reduced adhesive, migratory, and angiogenic capacity 22 and fail to respond to vascular endothelial growth factor. Mice treated with obese EPCs exhibited reduced EPC homing in ischemic hind limbs in vivo.

Etiology of obesity is complex, involving interrelated biochemical, neurological physiological, genetic, environmental, cultural and psychological factors. Adipose tissue can be considered as an endocrine organ that mediates biological effects on the metabolism and inflammation, contributing to the maintenance of energy homeostasis and the pathogenesis of obesity-related metabolic and inflammatory complications 4. Endothelial damage and dysfunction is considered to be a major underlying mechanism for the heightened cardiovascular burden that occurs with increased adiposity.

The goal of our study was to examine how cardiovascular risk factors and circulating CD34-positive cell numbers correlate when overweight subjects attempt to lose weight through calorie restriction. The particular weight loss regimen we examined consisted of severe calorie restriction along with vitamin supplements and administration of human chorionic gonadotropin (hCG), a hormone that encourages metabolic utilization of visceral fat reserves 23-26.

MATERIALS AND METHODS

Weight Loss Protocol

Our study consisted of fifty three participants, eighty percent of which were women, with ages ranging from 26 to 63. The starting body mass index of these subjects ranged from 30 to 67, while their body fat percentage ranged from 15% to 48% when they began treatment. All subjects gave written informed consent (as per Helsinki Declaration guidelines) and underwent the dietary program with the oversight of their primary care physician. Although, the program mainly aimed at overweight and obese people, it was open to anyone interested.

The weight loss program consisted of a 500 calorie per day dietary restriction in combination with the following:

Daily sublingual treatments by vitamin B12 (1,000 μg per day).

Oral supplements consisting of the following nutrients: 250 mg tyrosine, 2 mg β-glucan, 200 μg selenium, 1 mg folic acid, 5 mg iodine, 7.5 mg potassium iodide, 600 mg magnesium, 5 g vitamin D3, 60 mg coenzyme Q10, 150 mg lipoic acid, 340 mg acetyl-l-carnitine, 100 mg vitamin B complex, and a probiotic (2 billion CFU acidophilus with 2 billion CFU bifidus and 109 mg FOS).

Daily treatments of hCG nasal spray, at doses of 125 – 180 IU.

The very low calorie diet can be summarized as follows: breakfast consisted of coffee/tea with no sugar or one fruit serving, while lunch and dinner each consisted of 3.5 oz lean protein, a vegetable serving, bread serving, and a fruit serving. The program schedule was as follows: patients took supplements, B12, and hCG for two days prior to beginning a 36-day very low calorie diet. This was followed by a 35 day maintenance period during which calorie intake was gradually raised while restricting sugar and starch intake (at this point, hCG treatment stopped).

Subjects were supervised by a physician with weekly health evaluations. The following parameters were assessed weekly: body composition, including fat free mass (FFM), body fat (BF), total body water (TBW), intracellular/extracellular water, basal metabolic rate and body mass index (BMI). Blood chemistry parameters, including glucose, cholesterols, triglycerides and circulating CD34-positive cells were measured for nine subjects at the beginning and at the end of the study. Eight of the nine subjects who volunteered for blood work were female: they ranged in age from thirty to sixty-five years old. The lone male was forty years old.

Assay methods are described below.

Body composition

Body composition was measured by bioelectrical impedance analysis (BIA). The BIA is a non-invasive method for measuring body composition through reactance and resistance, the two components of impedance. Bioelectrical impedance analysis was performed by IMP DF50 (Company ImpediMed Limited). The fat-free mass, body fat, basal metabolic rate, total body water, extracellular water, intracellular water and body mass index were determined for each participant before dieting intervention and each six days following intervention.

Assay of lipid profile

A fasting serum was used for measurements of the lipid profile (total cholesterol, high-density lipoprotein cholesterol (HDL), low-density lipoproteins (LDL), triglycerides, very low-density lipoproteins (VLDV)) and glucose, by established clinical laboratory tests. Cholesterol, HDL cholesterol, and triglycerides were quantified by an auto-analyzer by an enzymatic method by using commercially available reagents (Genzyme Diagnostics). LDL cholesterol (in fasting samples) was determined by calculation.

CD34-positive cell measurements

The analysis of the CD34 positive cells was performed by adopting the gating strategy defined by the International Society of Haematotherapy and Graft Engineering (ISHAGE) guidelines 27. The method of the selection of stem/progenitor cells consisted from several criteria. Cells were selected that expressed CD34+ antigen, did not express CD45 antigen and exhibited low side-angle light scatter characteristics of blasts cells. This subpopulation was defined as of endothelial progenitor cells. Our decision to considered CD34 positive/CD45 negative circulating cells as “circulating EPCs” was based on the work 28, in which blood-derived cells from which endothelial cells in culture were developed were described as cells expressing CD34 antigen. It has been hypothesized that endothelial progenitor cells and hematopoietic progenitor cells have common precursor, the hemangioblast and both may be subsets of bone marrow-derived progenitor cells expressing CD34. Moreover, recent studies demonstrate that CD34+ cells not expressing leukocyte antigen (CD45-) form endothelial colony-forming units and those expressing CD45 demonstrate hematopoietic properties 29.

Specific cell surface staining was accomplished by incubating duplicate samples of a biological specimen (separated white blood cells) with two color CD45-FITC/CD34-PE reagents (Stem kit reagents, Beckman Coulter). In an additional test, the samples were stained with CD45-FITC/IsoClonic Control-PE reagent to check the non-specific binding of the CD34-PE monoclonal antibody.

Statistical analysis

All data were analyzed by Systat software (Systat Inc) and KaleidaGraph software. Variables were presented as mean values ±SD. Statistical analysis was done by linear regression model and paired non-parametrical test. Statistical significance was accepted if the null hypothesis could be rejected at p<0.05.

RESULTS

The distributions of mass loss and fat mass loss by all subjects during the diet are shown in Figure

Figure1

1.

Figure 1Distribution of the weight reduction and fat mass loss in all subjects participated in 36 days of the dieting program.

Subjects lost between 2.5 and 17.2 kg during the study, with the most weight loss occurring in subjects who started out the heaviest. All subjects achieved a decrease in body mass index during the study. The average BMI for participants at the start of the study was 34.0 ± 7.2 (SD), while that after the study was 28.5 ± 6.7 (SD). Using a paired Student’s t-test, the difference is highly significant (p = 0.0004). This indicates that weight loss and changes in body composition did occur during the time course of the study.

The weight reductions during the hypo-caloric diet and maintenance period for several patients are presented in Figure

Changes in body composition parameters are summarized in Table

Table1

1. Percent of decrease in total mass, fat free mass, intracellular/extracellular fluids and basal metabolic rate in subjects at the end of the study.These percentages did not vary systematically with the initial mass of the subjects. The decrease in body fat was substantial, and in most cases larger than the corresponding loss in lean mass. According to our data, the average percentage loss of lean mass was 5.7±4.7 and the average change in body fat was 12.4±8.7. The percentage loss in body fat among the most subjects was significantly larger (p = 0.04) than the percentage loss in lean mass, suggesting an improvement in body composition.

The treated subjects showed a decrease in their body mass index in an average of 8.1%±2.0%.

Changes in total body water had inverse correlation with changes in fat mass (r=0.86) and positive correlation with an increase in fat free mass (r=0.78). The level of intracellular water (ICW) correlated with fat mass and fat free mass changes during dieting. Intracellular water levels showed linear relation with fat free mass (r=0.9) and an inverse relation with fat mass (r=0.6). As intracellular fluid decreases due to different pathological conditions, the increase in intracellular water suggests improvement in cell health and nutritional status.

Basal metabolic rate decreased slightly in subjects during their treatment (4.1%±2.0%). The percentage of the decrease in BMR correlated with the percentage of weight loss. The decreasing of BMR is not desirable for dieters; however, the BMR decrease seen in our study is modest.

Statistically significant decreases in serum cholesterol levels were observed during the treatment. Lipid profile data are summarized in Table

Table2

2. Averaged blood chemistry parameters before and after the diet regiment are given. † indicates significant difference between “Pre” and “Post” (p < 0.05 using paired Student’s t-test).While glucose levels, triglycerides, very low density lipoproteins (VLDL), and high density lipoproteins (HDL) were not affected, subjects saw significant decreases in total cholesterol, low density lipoprotein (LDL), and overall in ratios of cholesterol and LDL to HDL. These variables are considered markers of cardiovascular disease. HDL protects arteries by transporting cholesterol away, while LDL can be deposited on arterial walls and clog arteries. Changes in the level of cholesterol and LDL for all participants are shown in Figures

Figures3,

The effect of the dieting program on the level of LDL in plasma.The effect of the dieting program on the level of cholesterol in plasma.For total cholesterol, the upper limit of the normal range is 200 mg/dL. Five of the subjects started the study above this threshold. All of these participants experienced cholesterol decreases during the diet treatment, with two returning completely to the normal range. The upper limit of the normal range for LDL is 100 mg/dL. Eight of the nine subjects started with above normal LDL, with three of them returning to normal levels during the treatment. Similar trends were seen with the cholesterol/HDL ratio (upper limit of normal being 5.0) and LDL/HDL (upper limit of normal being 3.6).

Regression analysis was conducted between body composition parameters and lipid profile parameters. The mass of body fat (BF) correlated strongly with the LDL to HDL ratio (r = 0.7), the cholesterol to HDL ratio (r=0.68) and inversely with HDL (r = 0.43).

Overall, these data indicated that the combination of a low calorie diet with hCG treatments reduced body fat as well as risk factors associated with cardiovascular disease.

Circulating CD34+ cells in peripheral blood, as a percentage of total leukocyte counts, were determined before and after the study. Weight loss was accompanied by a significant improvement in the number of circulating progenitor cells (p < 0.01). On average, the enhancement of progenitor cell numbers was roughly seventy percent. Figure

The ratio of CD34+ cells post diet to pre-diet as a function of percentage of body fat lost during the diet.A correlation also exists between CD34+ cells and the proportion of fat free mass (r = 0.80) for each subject. The changes in body fat, and the changes in lipid profile parameters, coincide with improvements in circulatory progenitor cell numbers.

To rule out the possibility that changing numbers of circulating CD34+ cells were simply part of an overall change in circulating white blood cells, we ran complete blood counts before and after treatment on the nine subjects who consented to blood work. Changes in blood cell counts with treatment varied among the nine subjects, with five experiencing overall decreases (the maximum downward change was thirty percent). All subjects showed a decrease in lymphocyte counts (the decrease ranged from eight to thirty-five percent).

The normalization of CD34-positive cell numbers to total peripheral blood mononuclear cell numbers, demonstrated that the numbers of CD34-positive cells per micro liter increase by an average of forty percent.

DISCUSSION

Obesity is frequently associated with traditional cardiovascular risk factors such as type 2 diabetes, hypertension, dyslipidemia, altered coagulation/fibrinolysis, and the other components of the metabolic syndrome 30. All these abnormalities create a state of constant and progressive damage to the vascular wall, manifested by a low-grade progressive inflammatory process and endothelial dysfunction 31, 32.

The endothelial cell damages due to dyslipidemia and proinflammatory cytokines have been demonstrated in studies 33, 34. Increased levels of triglycerides and lipoproteins in obese or overweight subjects correlate with impairment of endothelial function 35, 36. Endothelial cell damage due to dyslipidemia plays a critical role in the development and progression of atherosclerosis 37, 38.

Given the role of endothelial cell damage in obesity, our attention was turned to progenitor cells (CD34+/CD45- cells). These cells are thought to be early precursors of endothelial progenitor cells and function to replenish aging as well as damaged endothelial cells that line blood vessels. There is strong evidence of the role of circulating endothelial progenitor cells, including populations of CD34 positive cells presented in peripheral blood, in the maintenance of the vasculature and neovascularization 39, 40. In several studies, the number of circulating EPCs and their migratory activity have been reported to be reduced in patients with risk factor for coronary artery disease and negatively correlated with the Framingham cardiovascular risk score 41-43. Therefore, increasing the number of CD34-positive cells during treatment may provide an indicator of improvement of vascular health.

In our study, we analyzed the effect of weight loss on the improvement of lipid profile in plasma and the increase of the level of CD34+/CD45- cells in circulation.

The data from our study demonstrated that a combination of a very low calorie diet with hCG treatments, and supplements, decreases overall mass and body fat while improving lipid profiles. These benefits are accompanied by increases in circulating CD34+ cell numbers.

The weight loss protocol, which we used in our study, was developed in the 1950s 23, 24. Several studies have been done to examine the efficacy of hCG in treating obesity, with mixed results 44, 45. The main question has been whether the addition of hCG to a very low calorie diet enhances weight loss compared to dieting alone. While most studies report weight loss due to dieting, they disagree as to whether factors such as weight reduction, body proportion, and patient reported hunger level are affected by adding hCG to the diet. The issue is complicated by the fact that few of these studies were double-blind and placebo controlled. The experimental design used in the study 46 showed that the combination of the 500 calorie per day diet and hCG injections offered a significant benefit to dieters, offering increased weight loss and a decrease in hunger.

In our study, we did not compare hCG and diet to diet alone, but our work shows the direction that such a study should take, as we utilize additional measures such as body composition (fat free mass, body fat, total body water, BMI) for all participants and lipid profiles and circulating progenitor cell levels for a group of the patients to assess outcome.

Our study provided further evidence of this linkage, with fat loss showing a strong correlation with changes in lipid profiles and increases in circulating progenitor cell numbers. For participants who represented weight loss and fat mass loss, the maximum reduction in lipids that have effect on overall cardiovascular health was 29% for cholesterol, 38% for LDL, 26% for cholesterol to HDL ratio and 35% for LDL to HDL ratio.

The average improvement of CD34+ cells in circulation during dieting program was 69% ± 50%.

In conclusion, the weight loss program analyzed in our study resulted in the improvement of the number of CD34+ cells in circulation and the decrease of the values of cardiovascular risk factors. According to our study, the circulating progenitor cell number can be improved by diet and weight loss.
