FAT is now a two-way winner for Geest, with sales of lettuce soaring as the country gets more obese - and guilty. The food company has the weight-obsessed Brit in a pincer grip. Washed salad sales were up 25% in 2001, but to reward ourselves for being so healthy we pig out in the evening with pizzas and cakes also supplied by Geest, whose pizza sales grew 20% last year. Then we atone for the binge with another dose of diet food at lunchtime the next day.
