Pat has a few thoughts on your situation. First, it sounds like you are doing a good job of maintaining an active lifestyle and being aware of what you eat. The key to maintaining your weight is matching the calories taken in, with the calories used by your body. Calories are taken in through food and beverages and calories are used through a combination of your body's resting metabolic rate (metabolism) and the amount of activity/ exercise you do. Because I'm not sure of your exact diet, it is difficult to know if your weight gain is due more to decreased exercise or increased calorie consumption. In order to lose weight, you must eat fewer calories than you are expending through resting metabolism and activity. Resting metabolism is about 65-75% of your overall energy expenditure and typically ranges from about 1200-1800 calories per day depending on height, weight, and body composition (how much muscle mass vs. fat mass you have). We can't change resting metabolism substantially, but the amount of calories we expend exercising can vary drastically. The number of calories you "burn" during exercise varies with the intensity (how hard your body is working), frequency (how often you're exercising), and duration (how long you're exercising). You can maximize calorie expenditure by increasing intensity to the point where you're breaking a sweat and are breathing hard, increasing frequency of cardiovascular workouts to 3-4 times per week, and increasing duration to 45-60 minutes per session. Instead of doing aerobics twice a week, try cardiovascular exercise you do to challenge your muscles and "spice things up." Consider swimming, walking/ jogging, and hiking, cycling outdoors or on the stationary bike, or using the elliptical trainers. It's not so important which activities you do, but that you find some that fit into your schedule and that you enjoy! It's great that you're already strength training too. You might see better results if you lifted slightly heavier weights (challenging after 10 repetitions) 3 times a week rather than lightweights every day. Make sure to progressively increase the weight as you become stronger and it becomes too easy! As important as exercise is for health, it is also essential to look at your diet. You should monitor your diet to make sure that it is well balanced with plenty of fruits, vegetables, whole grains, lean meats, low-fat dairy products, and beans and minimal amount of fats and sweets. Watch out for extra calories that can sneak into the diet such as in sodas, fruit juices and drinks, coffee drinks, and condiments like cream cheese, sour cream, mayonnaise, butter, or salad dressings. 1 ladle-full of salad dressing at a salad bar can add 300 calories and 30 grams of fat! It is important to not skip any meals and allow yourself healthy snacks (such as granola bars, baby carrots, piece of fruit, cereal, yogurt) in between meals in order to maintain your energy levels and to prevent getting to hungry, which can lead to over-eating and less healthy food choices. You might consider consulting with a registered dietitian who can give you more individualized nutrition information and help you set and achieves nutrition goals. Finally, the medicine you are taking right now may also affect appetite. One of the known side effects of these drugs is actually a decreased appetite. However, these drugs can affect everyone differently and it would be best to consult your physician about the combination of the two and the side effects when taken together.
