Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.
As far as the measurement, yeah, those scales are garbage – but since it spits the data out, I figure I might as well right it down. I did a caliper test when I started and it gave me pretty similar results, but who knows. I am taking photos every week for my main source of tracking. I can see the progress there – and can definitely tell I have a lot of cutting yet to do! I’ll keep on pushing, I don’t know if I can hit 10%, but I will try for 12%.

### Not a jock? Find other ways to fit activity into your day: walk to school, jog up and down the stairs a couple of times before your morning shower, turn off the tube and help your parents in the garden, or take a stroll past your crush's house — anything that gets you moving. Your goal should be to work up to 60 minutes of exercise every day. But everyone has to begin somewhere. It's fine to start out by simply taking a few turns around the block after school and building up your levels of fitness gradually.

There's no magic number or one-size-fits-all recommendation, but doing a few calculations can give you an idea of how many calories you should eat for weight loss. First, figure out your basal metabolic rate (BMR), which is how many calories your body burns at rest, by just keeping basic functions running (like breathing). Experts use a formula called the Mifflin St. Jeor equation: (10 x your weight in kilograms) + (6.25 x your height in centimeters) – (5 x your age in years) – 161. You can also get your BMR measured at an endocrinologist's office. Then, factor in your activity level—try using this interactive calculator from the United States Department of Agriculture, which will give you a rough estimate of how much you should eat to maintain your current weight considering your BMR and activity level. To lose weight, you need to cut calories from that base number, either by deleting intake or increasing output. "Losing 1 to 2 pounds per week is reasonable, safe, and healthy for most," Cederquist says. Since 1 pound of fat is around 3,500 calories, you'd need to achieve a 500-calorie deficit each day to lose 1 pound each week.
Include servings of ungrouped veggies. You should also eat 4 to 5  c (950 to 1,180 mL) per week of vegetables that don’t fall into these groups, such as cabbage, cucumbers, lettuce, and zucchini. Portions for non-grouped veggies include a salad with 1 1⁄2  c (350 mL) of romaine lettuce and a sliced cucumber, 1  c (240 mL) of steamed zucchini, and 1  c (240 mL) of sauteed cabbage.[14]

```Losing weight or belly fat takes at least twice as long as it took to put it on. If you've had excess fat around your middle for a year, you should give your body at least that long to get rid of it. Reduce your calories, eat more vegetables, eliminate or strictly limit simple carbohydrates, quit alcohol and all greasy foods. Walk for 60 minutes a day and weight train twice a week for 20 minutes each session.

A different way of viewing weight loss identifies the problem as not one of consuming too many calories, but rather the way the body accumulates fat after consuming carbohydrates—in particular the role of the hormone insulin. When you eat a meal, carbohydrates from the food enter your bloodstream as glucose. In order to keep your blood sugar levels in check, your body always burns off this glucose before it burns off fat from a meal.
##### Second, weight is a weird thing that can go up or down for a dozen different reasons, many of which have nothing to do with fat or muscle being lost or gained. This is part of why I recommend weighing yourself daily and only paying attention to the weekly average (full detail here), not adjusting your calories based on what you see after 1 week (I suggest waiting 2-3 weeks before making changes to confirm that changes actually need to be made), and tracking your progress using more than just your weight on the scale (body fat percentage, measurements, pictures, mirror).

Whether that’s a floor, a couple of windows, the shower stall, bathroom tile, your car, or one of these everyday items no one cleans enough, a 150-pound person will burn about four calories for every minute spent cleaning. Scrub for 30 minutes and you could work off approximately 120 calories, the same number in a half-cup of vanilla frozen yogurt. If you do treat yourself with fro yo, stick with these nutritionist-approved toppings.
“A study published in Nutrition Journal found that participants who ate foods high in monounsaturated fats for lunch (in this case, half an avocado) reported a 40 percent decreased desire to eat for hours afterward. Monounsaturated fats from sources like olive oil, nuts and avocados can reduce cholesterol, promote weight loss, even boost memory.” — David Zinczenko, author of the  Zero Belly Cookbook
In addition to improving your health, maintaining a weight loss is likely to improve your life in other ways. For example, a study of participants in the National Weight Control Registry* found that those who had maintained a significant weight loss reported improvements in not only their physical health, but also their energy levels, physical mobility, general mood, and self-confidence.

A body of research out of Pennsylvania State University finds that eating water-rich foods such as zucchini, tomatoes, and cucumbers during meals reduces your overall calorie consumption. Other water-rich foods include soups and salads. You won’t get the same benefits by just drinking your water, though (but you will get other benefits of staying hydrated). Because the body processes hunger and thirst through different mechanisms, it simply doesn’t register a sense of fullness with water (or soda, tea, coffee, or juice).

A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising.
