As we mentioned above, eating in a calorie deficit is key. Jim recommends eating 500 calories less than your total daily energy expenditure, or TDEE. This is the number of calories you burn in a day, which is based on factors like age, height, sex, and activity level. To calculate what this number is and what your calorie target should be to lose weight, use this formula. Just make sure you don't go below 1,200 calories a day for women; in a previous interview, Jim said eating any fewer calories than that can slow down your metabolism and result in negative side effects like low energy, loss of hair, hunger pangs, and a negative impact on your menstrual cycle.
We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink just isn't as satisfying as eating a bowl of veggie- and protein-packed stir-fry. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.)
After dinner, wash all the dishes, wipe down the counters, turn out the light, and, if necessary, tape closed the cabinets and refrigerator. Late-evening eating significantly increases the overall number of calories you eat, a University of Texas study found. Learning how to stop late-night snacking can save 300 or more calories a day, or 31 pounds a year.
Frequent and sustained cardio training is one of the best ways to burn fat and boost metabolism. One of the best cardio exercises to perform is running, according to the American College of Sports Medicine, as it burns a high number of calories per hour and improves cardiovascular health. ACSM recommends training five days a week, with a minimum of 60 minutes per session.
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
How much fiber should I eat per day? Most Americans eat less fiber than the USDA daily recommendations suggest. This article looks at the guidelines for fiber intake in men, women, and children. We also talk about how fiber can help with weight loss, and discuss how much fiber is too much. Learn about good sources of dietary fiber and a handy meal plan. Read now
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
Popcorn is a whole grain, so it’s not unreasonable to include it on your green-light food list. However, even “natural” and “light” microwave popcorn is loaded with artificial ingredients, plus sodium and butter—and a ton of calories. This doesn’t mean you have to give up all popcorn though, as air-popped popcorn is a much better alternative. It only contains 30 calories per cup and you can customize it to your liking.
We don’t always eat simply to satisfy hunger. All too often, we turn to food when we’re stressed or anxious, which can wreck any diet and pack on the pounds. Do you eat when you’re worried, bored, or lonely? Do you snack in front of the TV at the end of a stressful day? Recognizing your emotional eating triggers can make all the difference in your weight-loss efforts. If you eat when you’re:
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
