Jaha, jag trodde att 3-4 insulintoppar av hyffsat mycket mjölkprodukter per dag sänker ämnesomsättningen.

Sänker ämnesomsättningen har det nog aldrig varit tal om. Sänker insulinkänsligheten, möjligen, men att en tränande, frisk individ skulle sänka sin insulinkänslighet i botten av mjölkprodukter tror jag inte ett skvatt på.

Här har du några referenser som pekar på att det är just mjölkprodukternas kalcium som är effektivt för att stimulera fettförbränning:

"Notably, dairy sources of calcium exert markedly greater effects in attenuating weight and fat gain and accelerating fat loss. This augmented effect of dairy vs. supplemental calcium is likely attributable to additional bioactive compounds in dairy that act synergistically with calcium to attenuate adiposity; among these are angiotensin converting enzyme inhibitory peptides, which limit angiotensin II production and thereby limit angiotensin II stimulation of adipocyte lipogenesis. These concepts are confirmed by both epidemiological and clinical data, which similarly demonstrate that dairy products exert a substantially greater effect on both fat loss and fat distribution compared to an equivalent amount of supplemental calcium."
"Calcium in the form of dairy exerted a greater effect on attenuating fat deposition than a comparable quantity of elemental calcium. Consistent with this, a recent randomized clinical trial demonstrated a markedly greater weight loss (7.0 vs. 1.7 kg) in patients maintained on a milk-based diet for 16 wk vs. those maintained on conventional hypocaloric diet at the same level of energy intake (16) . Although this difference was attributed to the novelty of the milk-based diet possibly contributing to a greater level of compliance, data presented herein suggest that this effect may also be attributable to suppression of 1,25-(OH)2-D and adipocyte Ca2+, with a consequent reduction in the efficiency of energy utilization."
