ASK A WEIGHT LOSS SPECIALIST
Where does body fat go when you lose weight? When you consume fewer calories than your body needs, your body turns to fat for energy. Your fat cells (triglycerides) provide the fuel for this energy. Through a series of complex metabolic processes, triglycerides are broken down into two different components — glycerol and fatty acids — which are absorbed into your liver, kidney and muscle. Here, these components are further broken down by chemical processes that ultimately produce energy for your body.
The heat generated through these activities is used to help maintain your body temperature. The waste products that result are water and carbon dioxide. You excrete water primarily in urine and sweat and carbon dioxide in air exhaled from your lungs.
What’s the best way to boost my metabolism? Metabolism is the process your body uses to burn calories for energy. Because metabolism naturally slows with age, you may need fewer daily calories as you get older. But your metabolism doesn’t dictate your weight. To lose excess weight, include physical activity in your daily routine. The calories you’ll burn will help promote weight loss. Second, start a strength training program. Muscle tissue burns more calories than fat tissue does, even when you’re at rest. Whether you use hand-held weights, resistance tubing or another type of resistance, you’ll reduce your body fat, increase your lean muscle mass and burn calories more efficiently.
Can I lose weight if my only exercise is walking? Consuming fewer calories is often the most effective way to lose weight. Still, an increase in physical activity is an important part of any weight-loss program. And walking is a great way to get started. For motivation, do the math: To lose 1 pound, you must burn 3,500 calories. If you cut 250 calories from your daily diet, you could lose that pound in about two weeks. If you add 30 minutes of brisk walking to your daily routine, you could burn another 150 calories a day. Make that 60 minutes of brisk walking and you could burn about 300 calories a day. Of course, the more you walk and the quicker the pace, the more calories you’ll burn. Keep it up and you’ll walk your way to a healthy weight. Better yet, walking can help you keep the weight off for good.
Which is better for losing weight: cutting calories or increasing exercise? There was a
study published in the Journal of Clinical Endocrinology & Metabolism. This six-month study examined the effects of diet alone (25 percent fewer calories consumed) versus diet plus exercise (12.5 percent fewer calories consumed and 12.5 percent more calories burned) in overweight but otherwise healthy adults. Researchers hypothesized that the diet plus exercise group would lose more body fat, but results showed equal amounts of weight and fat lost in both groups. This confirms that weight loss is all about calories: If you burn more calories than you eat, you’ll lose weight. It doesn’t mean exercise isn’t important. As we all know exercise has many health benefits.
