I eat lots of healthy fats and no sugar or wheat. I'm borderline underweight. When you eat such a diet, your insulin levels stay low. High insulin is what causes your body to convert sugar to fat and store it. Low insulin causes your body to burn your fat reserves. I just got back from a 5 day, 50 mile backpacking trip where I averaged about 1000 calories a day. Not once was I hungry.
The arctic explorers weren't gaining body fat from the fats they ate, they were burning them almost immediately.
