Jaki preperat typu Fat Burner warto kupic?

Czy Fat Burner Plus z Olimpu nie ma zbyt małych dawek? Np. L-karnityny zawiera
tylko 75mg. Czy choliny i inozytolu ma w wystarczajacej dawce? I co z
pozostałymi składnikami Fat Burnera Plus Olimpu, czy są rzeczywiscie potrzebne?

      zaden. Albo zdolasz zrzucic co trzeba dieta i cwiczeniami albo ilekroc pojawia
      sie klopot siegasz po "wspomagacze". Wedlug naukowcow studiujacych odchudzanie
      w skrocie istnieja trzy rodzaje preparatow:

      - szkodliwe i uzalezniajace (amfetaminy, efedryna)
      - nieskuteczne (np CortiSlim obiecujacy ze jakims cudem sterydy w organizmie
      ponaprawia)

      - umiarkowanej skutecznosci (metformina etc.). W skali roku kiedy mowimy o
      pacjentach z BMI ok 30% roznice spadku wagi sa bodajze ok. 5-10% w stosunku do
      grupy na tej samej diecie bez preparatu.

      Ergo: zamiast pakowac sie prochami idz na spacer.

        Też tak kiedyś myślałam. Jednak w kilku wątkach znalazłam opinie joggera, że
        warto dietę i ćwiczenia wspomagać preparatami zawierającymi L-karnitynę, cholinę
        i inozytol, by przestawić organizm na spalanie tłuszczeów, m.in.

        O przydatności L-karnityny przy treningu przekonałam się na własnej skórze. A
        teraz chcę wiedzieć coś więcej na temat tzw. Fat Burner'ów: co warto stosować, a
        co jest tylko reklamą.

          Wytrenowanym sportowcom karnityna zdecydowanie nic zauwazalnego nie daje na
          podstawie tego przegladowego artykulu. Na szczescie nie jest toksyczna w dawkach
          ktore sa przyjmowane. Czy dziala jednak na zwyklych smiertelnikow a nie elite
          athlets.

          Carnitine and sports medicine: use or abuse?

          Brass EP.

          Carnitine has important roles in skeletal muscle bioenergetics. Skeletal muscle
          carnitine deficiency is associated with profound impairment of muscle function.
          It has thus been natural to ask if carnitine supplementation can improve
          skeletal muscle function and athletic performance in healthy individuals. Oral
          carnitine doses of several grams cause no significant clinical toxicity, further
          encouraging the use of carnitine as a supplement. Despite this strong foundation
          and 20 years of research, no compelling evidence exists that carnitine
          supplementation can improve physical performance in healthy subjects. The
          available data have been reviewed in recent publications. Several key issues are
          relevant to a potential therapeutic benefit of carnitine supplementation, and
          addressing these may provide insight into trials of carnitine therapy in healthy
          subjects: (1) Can carnitine supplementation increase skeletal muscle carnitine
          content in healthy subjects? Muscle carnitine content is not easily increased
          with carnitine supplementation. This reflects both the systemic pharmacokinetics
          of carnitine and the systems controlling transmembrane transport of carnitine in
          skeletal muscle. (2) How much carnitine is required to support optimal
          metabolism in skeletal muscle? Data are not available to definitively define the
          relationship between muscle carnitine content and muscle metabolic function.
          Extrapolation of data from several models suggests that very low amounts of
          carnitine are required to support muscle function. (3) Does carnitine
          supplementation alter energy homeostasis in healthy subjects? Several, but not
          all, studies suggest that subjects on carnitine supplementation have altered
          regulation of fuel homeostasis. However, the mechanisms of these changes, the
          tissues affected, and the relevance of these phenomena to exercise performance
          are all ill defined. (4) How can changes in performance be assessed in healthy
          subjects? Most studies have failed to demonstrate an objective performance
          improvement in healthy subjects taking carnitine. However, these negative
          studies must be interpreted with caution. Performance studies in athletes are
          conducted against a background of aggressive training regimens and nutritional
          interventions. Small changes, which may be very important to the athlete, may be
          very hard to objectify in the laboratory. Assessments must differentiate between
          changes in maximal aerobic capacity, ability to sustain effort at varied
          workloads, and the subject's perception of exertion. The interaction of
          carnitine supplementation with exercise training may be particularly important
          on theoretical and experimental bases. Systematic research in each of these
          areas is required to better understand the physiology, biochemistry, and
          pharmacology of carnitine supplementation. While data do not allow a conclusion
          to be drawn that carnitine is beneficial, the negative has not been proven either.

          Common dietary supplements for weight loss.

          Saper RB, Eisenberg DM, Phillips RS.

          Harvard Medical School, Boston, Massachusetts, USA.

          Over-the-counter dietary supplements to treat obesity appeal to many
          patients who desire a "magic bullet" for weight loss. Asking overweight patients
          about their use of weight-loss supplements and understanding the evidence for
          the efficacy, safety, and quality of these supplements are critical when
          counseling patients regarding weight loss. A schema for whether physicians
          should recommend, caution, or discourage use of a particular weight-loss
          supplement is presented in this article. More than 50 individual dietary
          supplements and more than 125 commercial combination products are available for
          weight loss. Currently, no weight-loss supplements meet criteria for recommended
          use. Although evidence of modest weight loss secondary to ephedra-caffeine
          ingestion exists, potentially serious adverse effects have led the U.S. Food and
          Drug Administration to ban the sale of these products. Chromium is a popular
          weight-loss supplement, but its efficacy and long-term safety are uncertain.
          Guar gum and chitosan appear to be ineffective; therefore, use of these products
          should be discouraged. Because of insufficient or conflicting evidence regarding
          the efficacy of conjugated linoleic acid, ginseng, glucomannan, green tea,
          hydroxycitric acid, L-carnitine, psyllium, pyruvate, and St. John's wort in
          weight loss, physicians should caution patients about the use of these
          supplements and closely monitor those who choose to use these products.
