Todd,
 
Atkins actually suggests some foods for his  fat-fast: 
macademia nuts
cream cheese or brie
whipped cream and sugar free syrup
tuna or chicken salad (1/3 cup tuna with 2 tb of mayo)
full fat sour cream with sugar free syrup
fatty pate
2 oz beef chuck cooked in 2 tb olive oil - don't drain
 eggs with  bacon
two egg yolks with 1 tb mayo

Atkins of course has people first start on 1000 calories a day of 90% fat, 
10% protein for a week then moves them up to 1200 calories -- but if one just 
eats to satiety -- the calories shouldn't matter -- problem is with the small 
'mass' of food -- probably takes some time to adjust to small amount of 
volume. 

Was out looking at DIT/BAT stuff (it's a hot research area, especially since 
leptin appears to induce BAT thermogenesis) and my suspicion that temperature 
might play a role is confirmed:

Nonshivering thermogenesis induced in brown adipose tissue (BAT) during 
high-fat feeding is mediated through uncoupling protein 1 (UCP1). UCP2 is a 
recently identified homologue found in many tissues. To determine the role of 
UCP1 and UCP2 in thermoregulation and energy balance, we investigated the 
long-term effect of high-fat feeding on mRNA levels in mice at two different 
ambient temperatures. We also treated mice with the anorectic peptide 
enterostatin and compared mRNA levels in BAT, white adipose tissue (WAT), 
stomach, and duodenum. Here, we report that high-fat feeding at 23 degrees C 
increased UCP1 and UCP2 levels in BAT four- and threefold, respectively, and 
increased UCP2 levels fourfold in WAT. However, at 29 degrees C, UCP1 
decreased, whereas UCP2 remained unchanged in BAT and increased twofold in 
WAT. Enterostatin increased UCP1 and decreased UCP2 mRNA in BAT. In stomach 
and duodenum, high-fat feeding decreased UCP2 mRNA, whereas enterostatin 
increased it. Our results suggest that the regulation of uncoupling protein 
mRNA levels by high-fat feeding is dependent on ambient temperature and that 
enterostatin is able to modulate it.
