hmmm.... this is this the problem when young players cherry pick under the influence.....of confirmation bias.
When one finds an interesting paper by a key researcher in a field, it's a good idea to search for their follow up papers.....such as no. 8 below!

Abstract
Ten pairs of normal men were overfed by 5 MJ/d for 21 d with either a carbohydrate-rich or a fat-rich diet (C- and F-group). The two subjects in each pair were requested to follow each other throughout the day to ensure similar physical activity and were otherwise allowed to maintain normal daily life. The increase in body weight, fat free mass and fat mass showed great variation, the mean increases being 1·5 kg, 0·6 kg and 0·9 kg respectively. No significant differences between the C- and F-group were observed. Heat production during sleep did not change during overfeeding. The RQ during sleep was 0·86 and 0·78 in the C- and F-group respectively. The accumulated faecal loss of energy, DM, carbohydrate and protein was significantly higher in the C- compared with the F-group (30, 44, 69 and 51 % higher respectively), whereas the fat loss was the same in the two groups. N balance was not different between the C- and F-group and was positive. Fractional contribution from hepatic de novolipogenesis, as measured by mass isotopomer distribution analysis after administration of [1-13C]acetate, was 0·20 and 0·03 in the C-group and the F-group respectively. Absolute hepatic de novo lipogenesis in the C-group was on average 211 g per 21 d. Whole-body de novo lipogenesis, as obtained by the difference between fat mass increase and dietary fat available for storage, was positive in six of the ten subjects in the C-group (mean 332 (SEM 191) g per 21 d). The change in plasma leptin concentration was positively correlated with the change in fat mass. Thus, fat storage during overfeeding of isoenergetic amounts of diets rich in carbohydrate or in fat was not significantly different, and carbohydrates seemed to be converted to fat by both hepatic and extrahepatic lipogenesis.

Hepatic and whole-body fat synthesis in humans during carbohydrate overfeeding
A Aarsland, D Chinkes, and R R Wolfe
Am J Clin Nutr June 1997 vol. 65 no. 6 1774-1782
"We conclude that the liver plays a quantitatively minor role when surplus carbohydrate energy is converted into fat in the human body. The main site for fat synthesis is likely to be the adipose tissue."

Fat and carbohydrate overfeeding in humans: different effects on energy storage.
Am J Clin Nutr July 1995 vol. 62 no. 1 19-29T J Horton, H Drougas, A Brachey, G W Reed, J C Peters, and J O Hill
"Carbohydrate overfeeding produced progressive increases in carbohydrate oxidation and total energy expenditure resulting in 75-85% of excess energy being stored. Alternatively, fat overfeeding had minimal effects on fat oxidation and total energy expenditure, leading to storage of 90-95% of excess energy. Excess dietary fat leads to greater fat accumulation than does excess dietary carbohydrate, and the difference was greatest early in the overfeeding period."

Glycogen storage capacity and de novo lipogenesis during massive carbohydrate overfeeding in man
Am J Clin Nutr August 1988 vol. 48 no. 2 240-247
K J Acheson, Y Schutz, T Bessard, K Anantharaman, J P Flatt, and E Jéquier
"Glycogen storage capacity in man is approximately 15 g/kg body weight and can accommodate a gain of approximately 500 g before net lipid synthesis contributes to increasing body fat mass. When the glycogen stores are saturated, massive intakes of carbohydrate are disposed of by high carbohydrate-oxidation rates and substantial de novo lipid synthesis (150 g lipid/d using approximately 475 g CHO/d) without postabsorptive hyperglycemia."

Stimulation of thermogenesis by carbohydrate overfeeding. Evidence against sympathetic nervous system mediation.
J Clin Invest. Apr 1983; 71(4): 916–925.
S Welle and R G Campbell
Daily carbohydrate intake of seven men with normal weight was limited to 220-265 g/d for 6 d and then increased to 620-770 g/d for 20 d, while intake of protein, fat, and sodium remained constant. Carbohydrate overfeeding increased body weight by 4.8%, basal oxygen consumption (VO2) by 7.4%, BMR by 11.5%, and serum triiodothyronine levels by 32%. Overfeeding did not affect the thermic effect of a standard meal.
