The Effect of a High Protein Diet Versus a Low Fat Diet on Body Weight After Smoking Cessation
2017年6月28日 更新者：Tor Ole Klemsdal、Oslo University Hospital
The Effect of a High Protein Diet Versus a Low Fat Diet on Body Weight and Composition, Total Energy Expenditure, Metabolic Risk Factors and Eating Behavior After Smoking Cessation
The purpose of this study is to determine whether subjects following a high protein diet will gain less in weight after smoking cessation compared to subjects following a low fat diet due to the effects of protein on metabolic rate and hunger.
研究概览
详细说明
Sustained smoking cessation is one of the most effective therapies to avoid premature morbidity and mortality.
However, weight gain associated with nicotine withdrawal may attenuate some of the beneficial health effects and is cited as a major obstacle to quit smoking.
The mechanism for the weight gain is not elucidated but reduced resting metabolic rate, reduced total energy expenditure, increased caloric intake and changes in fat metabolism may be involved.
Elucidating effective strategies to prevent or reduce post-cessation weight gain may improve health outcomes of smoking cessation.

实验性的：The High Protein Diet Group
The high protein diet (25% energy from protein, 55% energy from fat, 20% energy from carbohydrate) will be hypo-caloric and achieved by restricting the amount of sugar containing foods and drinks, reducing the intake of bread, rice, pasta, fruits and fruit-juices and increasing the intake of vegetables (instead of bread, rice, pasta and potatoes) and increasing the amounts of protein (from chicken, fish, and meat) and fat from oil and dressings for lunch and dinner and by choosing nuts and protein-rich yoghurts, egg, cheese, chicken wings, shellfish, fish and fish products as snacks.

The High Protein Diet Group was advised to have 25 energy percent from protein, 55 energy percent from fat, 20 energy percent from carbohydrate in the diet and the Low Fat Diet Group was advised to have 30 energy percent from fat, 20 energy percent from protein, 50 energy percent from carbohydrate in the diet.

有源比较器：The Low Fat Diet Group
The low fat diet (30% energy from fat, 20% energy from protein, 50% energy percent from carbohydrate) will be hypo-caloric and achieved by choosing low-fat diary and meat products, restricting amounts of visible fat and fatty snacks and increasing intake of whole meal bread, muesli, brown rice, whole meal pasta in the main meals and by choosing yoghurt with muesli, oat porridge with milk, fruits and hard bread with jam and soft gout-cheese as snacks.
