Mr. Lybrate-user, to prevent diabetes one has to adapt a modified lifestyle. Which means maintain near normal weight, exercise daily for 1 hour or more, take restricted diet giving exact calories based on ideal body weight.
Avoid too much of sweets, deep fried foods, junk foods, pastries, sweetened aerated drinks, sweet corn syrup containing products, high fat milk products and highly processed products. Sugarless tablet alone are not much of help.
