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).
Fast forward to our second wedding (we were both previously married to less than fit minded partners), two new jobs, new city, new house, new life - racing took a back burner but Lee and I continued to run together, swim occasionally and he finally took up cycling. We would go to the gym together or separate so I could body pump or spin, and I picked up barre, but the nutrition was waning since my mind thought I was still on a pass but my body wasn't agreeing. 3 years after working from home and a reduced "training" schedule, half my wardrobe no longer fit. A clear sign something needed to change. Add on turning 39 and that photo from our first 1/2 marathon that kept reminding me we needed to shape up.
• If you’re in a caloric deficit: you’ll be better off choosing foods that are low in energy density and high in nutrient density. These foods will help keep you full when calories are low. Energy-dense foods like cereal, chocolate bars, ice cream, Pop-Tarts, etc. are less filling and thus less satiating. This is why you can eat a chocolate bar and be hungry again ten minutes later, while a [calorically] comparable meal filled with protein and veggies will keep you fuller for longer.
Dietary fats are essential molecules that cannot be ignored in a fat loss plan because of the important roles they play in many different bodily processes. Fat is the most energy dense nutrient. Whereas protein and carbs both contain 4 calories per gram, fat contains 9 calories per gram. The downside to fat is that it is easily stored as adipose tissue (fat).
Weight training is the ultimate way to burn calories fast. "A pound of muscle burns up to nine times the calories of a pound of fat," explains Richard Cotton, M.A., chief exercise physiologist for myexerciseplan.com. Weight training increases your resting metabolic rate, which is the number of calories you burn while sitting on your butt. What's more, it gives your metabolism an added boost after you exercise, staying in overdrive for up to two hours after the last bench press, according to a study published in Medicine & Science in Sports & Exercise. Strapped for time? Try these quick moves: squats, bench step-ups, lunges, push-ups, pull-ups and planks. In a pinch, just do single sets of 10 for each exercise — you'll get optimal results for the time invested.
Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.
The least intrusive weight loss methods, and those most often recommended, are adjustments to eating patterns and increased physical activity, generally in the form of exercise. The World Health Organization recommended that people combine a reduction of processed foods high in saturated fats, sugar and salt and caloric content of the diet with an increase in physical activity.
The prevailing formula for a long time on how much fat you’re going to burn was calories in minus calories out, based on your basal metabolic rate (BMR) and exercise efforts, explains strength and performance specialist Joel Seedman, Ph.D., owner of Advanced Human Performance in Atlanta. But with all the different biochemical reactions in the body, hormonal response, and endocrine function, there are an infinite number of factors that can affect how your body is storing and breaking down calories.
