If this article is to be believed gardeners are thinner and tend to have a better diet. The article suggests that women gardeners are up to a dress size smaller and were 46% less likely to have a weight problem. Researchers found that exercise is not the only benefit of gardening, the home grown fruit and vegetables can also make your diet healthier. Previous studies have found that gardening carries a host of benefits such as raising your zest for life and increasing happiness. All of these things make me think that those many hours at the allotment are well spent.
