Brand New Weight Loss Studies

Hi there. I hope you are having a great week and are starting to recover from the holiday weekend.

Chances are you put on a few pounds this weekend and are ready to get them off as fast as possible, along with maybe a few more unwanted pounds. I just came across a few great studies in the latest American Journal of Clinical Nutrition that may help you get rid of some unwanted fat or just help you get on a healthy path.

Study 1: Short sleep duration increases energy intakes but does not change energy expenditure in normal-weight individuals

This title pretty much sums up the entire study. Here researchers took a group of individuals and compared their diet and energy expenditure after habitual 4hr of sleep per night and 9hr per night. What they found that participants were eating about 300 calories more per day on less sleep and especially increased their fat intake. The real problem is they did not increase their energy expenditure at all on days they ate more. So this group would gain about a 1lb every 10 days or 30lbs in a year if they were to continue this habit.

This can be an easy fix. Make sure you are getting adequate sleep every night to avoid increased calorie consumption.

Study 2: Green tea intake lowers fasting serum total and LDL cholesterol in adults: a meta-analysis of 14 randomized controlled trials

Again the title says it all here. In this study researchers wanted to look at green tea's effect on cholesterol levels. Green tea has already shown many great health benefits including possible increased fat burning. This study reviewed 14 eligible randomized controlled trials using green tea. They found that through all of these studies, 1136 subjects, there was a significant reduction in total cholesterol and LDL levels. There was no effect on HDL levels, however.

Study 3: Cruciferous vegetable consumption is associated with a reduced risk of total and cardiovascular disease mortality

And our final study involves vegetable consumption, which I know most people tend to struggle with. Asian populations tend to consume large amounts of cruciferous vegetables and other plant based foods. This study wanted to determine the effects of a diet high in these cruciferous vegetables. This is just a family name for certain vegetables. Some of the more popular ones are kale, collard greens, cabbage, brussel sprouts, cauliflower, and broccoli.

This study observed women for 10 years and evaluated diet program. They found that those who consumed higher cruciferous vegetables and fruits lived longer and were less likely to suffer from cardiovascular disease.

I know these three studies are a little random but I thought they are very useful tips for anyone trying to live a healthier lifestyle. Key points:

1. Sleep more
2. Drink Green Tea
3. Eat more vegetables
