If you were to pinpoint and identify one exact, specific reason why you’re not losing weight, or in fact why you’re gaining weight, it most likely wouldn’t be the reason you think it is. You may come up with things such as “I don’t work out enough”, or “It’s genetic”, or “It’s my diet”. You may even identify certain foods in your diet like “carbs”, or bread, or red meat. You’d be on the right track in assessing your situation, but it’s not exactly just one or several of these variables to be exact.
The number one reason why you’re not losing weight is because you are taking in more calories than you are using. The reason you are gaining weight if you are is because you are consuming “more” calories than you expend.
The body’s resting metabolic rate varies per person, but it’s roughly between 1500-2500 calories per day for each person, and this depends on body weight, body mass, muscle mass, and some genetics. This doesn’t take into account or factor in any additional calories you use up each day, including walking around, doing chores, or exercising. If you live relatively sedentary (sitting around most of the time watching tv or in front of the computer screen), you won’t burn up much more calories, and the weight will go on much easier and faster.
If you exercise regularly at least five days a week for at least 30 minutes at a moderate to high intensity, it will help you and go a long way at preventing weight gain and fat storage. Also, cutting out “empty” calories that don’t fill you up such as sugar will eliminate a good deal of extra calories as well.
So if you want to lose weight or stop gaining weight, the best solution is to get moving and cut out sugar and saturated fat by increasing your green vegetable and fruit intake, low in calories and full of dietary fiber.
