Time for a Tomato

I was visiting Melbourne recently and a former student came up to me and said “Hans, is it OK for me to eat tomatoes on The Ratchet Diet?” I think he was asking this question because of the confusion about whether a tomato is a fruit or a vegetable. Like many of my weight loss students, he was very well aware that I try to discourage people on a diet from eating too much fruit. However I was able to put his mind at rest. The tomato is a fruit but its one of the safest and healthiest fruits for the keen dieter. In fact I very rarely have a salad that does not include at least one tomato in it.
