Eftersom fett kostar kroppen mer att bryta ner än kolhydrater, så kan man äta mer totalenergi än man till synes behöver, och ändå gå ner i vikt. Motion som metod vid viktminskning är överskattat, och motsvarar endast ett par % av viktnedgången, enligt Claude Marcus, överläkare/professor och landets ledande expert på övervikt och fetma. Som jag skrev innan, jag tror mer på honom än King Grub.
Med metabola "kostnaden" av makronutrienterna är: alkohol, protein, kolhydrat och fett sist.

Citat:
KLC and NLC diets were equally effective in reducing body weight and insulin resistance, but the KLC diet was associated with several adverse metabolic and emotional effects. The use of ketogenic diets for weight loss is not warranted.
Am J Clin Nutr. 2006 May;83(5):1055-61. Ketogenic low-carbohydrate diets have no metabolic advantage over nonketogenic low-carbohydrate diets.
Citat:
Favorable changes in leptin that accompany weight loss are not sustained in individuals who followed a low-carbohydrate diet for one year. A low-carbohydrate diet had no significant effect on insulin, adiponectin, TNF-alpha, or CRP compared to a low-fat diet at 36 months.

Citat:
When energy intake was matched, the VLC-HF diet provided no advantage in weight loss or in improving those components of the metabolic syndrome induced by dietary obesity and may delay loss of hepatic and visceral fat as compared with an HC-LF diet.

Energy cannot get lost; energy that is not expended will be stored. As the digestibility of foods is not affected by intake level or subject, energy storage during overfeeding can be calculated as the difference between energy intake and energy expenditure.
With carbohydrate overfeeding 75 to 85% of the excess energy was stored and the remaining expended, while with fat overfeeding 90 to 95% of the excess energy was stored, but there was no difference in fat storage after 14 d between the two diets fed isoenergetically to the same subjects.
