Weight Loss

Health and Wellness -Weight Loss

A study in 2007 challenged the popular notion that a high carbohydrate, low-fat slimming plan only works if there’s little or no sugar involved.

The exclusion of sugar (sucrose) is normally advocated in a weight loss diet but now researchers have found that it is not necessary to achieve weight reduction.

A team of scientists at Queen Margaret University, Edinburgh found that instead a low-fat, high-carbohydrate diet (containing sucrose) combined with physical activity achieved the greatest health benefits in overweight subjects. In fact, the palatability of sucrose may even help dieters stick to their eating plans.

As part of a 12-week programme, 69 overweight women (average age 41 years; average body mass index 32 kg/m2) were given advice on either diet, physical activity or both. A fourth group acting as the ‘control’ received no advice.

Measures of body fat and markers of heart disease risk (such as waist circumference and cholesterol levels) were collected at the beginning and end of the trial.

The advice followed healthy eating guidelines and recommended: a reduced daily calorie intake, which was low in fat (35 percent of calorie intake) and high in carbohydrates (55 percent of calorie intake) that one tenth of their total calorie intake included sugar.

An increase in activity levels focused on including sixty minutes of brisk walking per day. The researchers noted that after three months, the group combining the sugar-containing diet and activity changes recorded the greatest positive health outcomes, compared with diet or exercise alone.

Significant reductions were observed in body weight (4.7 percent loss), waist circumference and percentage body fat. Measures of blood fats (total cholesterol and LDL) had also significantly improved. The study not only highlights the need for dietary advice to accompany increased physical activity in order to achieve weight loss, but also demonstrates that a low-fat, high-carbohydrate, sucrose-containing diet combined with increased exercise can be effective for slimming.
