As chronic obstructive pulmonary disease (COPD) advances, about 35% of patients experience severe weight loss called pulmonary cachexia, including diminished muscle mass. Around 25% experience moderate to severe weight loss, and most others have some weight loss. Greater weight loss is associated with poorer prognosis. Theories about contributing factors include appetite loss related to reduced activity, additional energy required for breathing, and the difficulty of eating with dyspnea (labored breathing).
In this study, eating more protein helped overweight men preserve more lean mass when they lost weight. The men were put on a diet that gave them either 15% or 25% of energy from protein. But here’s a huge difference that you won’t see in the abstract: the low-protein group was vegetarian; the high-protein group got meat. (The study authors never explain why on earth they would do it like that).
Don’t buy your tickets to Bonnaroo just yet; the kind of acid that will help you slim down is the stuff right inside your cabinet. A 12-week study published in Bioscience, Biotechnology, and Biochemistry reveals that obese study subjects who made vinegar part of their diet dropped more belly fat than a control group, and other research suggests that acidic foods, like vinegar, can increase the human carbohydrate metabolism by as much as 40 percent.
I am into day 2 of my 6th week of my calorie deficit. For weeks 1 through 3 I wasn’t exercising beyond my daily dog walks. I adjusted my BMR and calorie deficit to reflect the 6lbs I lost. Week 4 I started working out 3x’s a week – moderate weight lifting and moderate cardio. At beginning of week 5 had lost a total of 10 lbs, but wanted to wait until this weekend to make my adjustments based on whatever I lost in week 5. Well, I got on the scale, and the damn thing told me I gained a pound.
The one that concerned me after reading this was the lancet. According to the website, 3 groups of people had 3 different diets, each diet only containing 1000 calories. One was 90% of calories from carbs, one 90% of calories from fat, and one 90% of calories from protein. In the end, the group that ate 90% fat lost the most average weight, and the group that ate 90% carbs ended up gaining weight on average. How does this make sense if they all had the same calorie intake?
Well, weight training plays a huge (and required) role in maintaining muscle/strength while losing fat, but strictly in terms of causing fat loss, weight training doesn’t have much of an effect at all because it just doesn’t burn THAT many calories. Cardio generally burns more calories than weight training, but it’s still not THAT huge of an amount, especially for the amount of time it takes.
What does a HIIT workout look like? You could jog for two minutes, sprint for one minute, jog for two minutes, sprint for one minute. Or you could do a HIIT workout on a bike, or by running up stairs and then jogging back down. The key is that you go relatively all out for a short period of time, then recover by maintaining a moderate level of intensity, then go again.
