The reason we’re suggesting 45 minutes instead of the typical 30 as one of the easy ways to lose weight is that a Duke University study found that while 30 minutes of daily walking is enough to prevent weight gain in most relatively sedentary people, exercise beyond 30 minutes results in weight and fat loss. Burning an additional 300 calories a day with three miles of brisk walking (45 minutes should do it) could help you lose 30 pounds in a year without even changing how much you’re eating. Here are 20 hidden reasons your diet isn’t working.
… that lists sugar, fructose, or corn syrup among the first four ingredients on the label. You should be able to find a lower-sugar version of the same type of food. If you can’t, grab a piece of fruit instead, especially if you show signs you’re eating too much sugar. Look for sugar-free varieties of foods such as ketchup, mayonnaise, and salad dressing. Also, avoid partially hydrogenated foods, and look for more than two grams of fiber per 100 calories in all grain products. Finally, a short ingredient list means fewer flavor enhancers and empty calories. Sounds impossible, but you can actually learn how to give up sugar without missing it.

Some people feel better supplementing the already active T3 (sometimes prepared from pig thyroid glands), as it can give a stronger effect than the T4 hormone, but its effect is often harder to control. Swedish healthcare rarely prescribes or offers such T3 treatment, as it often lacks advantages and may pose a risk when doses are high for an extended period of time.
During the first week of a reduced calorie and carbohydrate diet, you will flush a lot of excess water and lose weight rapidly. This is neither unhealthy, nor an indication of what your rate of weight loss will be like during weeks 2 and 3. With that said, men should expect to see an 8 to 12 pound loss during these 3 weeks, and women will likely lose 5 to 10 pounds. 
Ah, the über-popular “know your why” strategy. One Brown University study found that when people are motivated to lose weight for appearance and social reasons, they stick with their weight-loss habits for significantly less time than those who are motivated by their health. After all, these external motivators (like looking a certain way or fitting into a cultural ideal) aren’t going to get you going when you’re feeling down, have had a bad day, or are frustrated with a plateau, Albers says.
IBS, or irritable bowel syndrome, is the most common gastrointestinal disorder. IBS symptoms include nausea, diarrhea, constipation, stomach pain, and bloating—So. Much. Bloating. While the causes aren’t all known, it’s thought to be linked to lifestyle factors like diet, exercise, hormones, and stress. Sufferers often find that making changes in these areas eliminates or reduces their IBS (and their stomach circumference!). Here’s how these 10 myths about fat can keep you from losing weight.
Salt, in moderation, is a good thing—the mineral is necessary for a healthy heart and brain. But too much salt and you’ll retain water, bloating up like a water balloon. Cutting salt is one of the primary ways to drop extra water weight (one reason you may see a big weight loss when starting a new diet!). Move the salt shaker off your table so you’ll get out of the habit of routinely salting all your food. Then if you taste your food and still really want salt you can still stand up and get some. For more weight loss benefits, add these fat-burning foods to your plate to help you lose weight.
Making a smoothie and ordering a smoothie at a shop are two very different things. When you make a smoothie yourself, you can measure the exact amount of fruit, swap water or almond milk for juice, and avoid any additional sweeteners. But many pre-made smoothies contain between 600 to 1,000 calories, on average, and are loaded with sugar. “An average height woman who is trying to lose weight is probably on a 1,200 to 1,400 calorie diet,” Amidor says. “So consuming one smoothie with 1,000 calories can easily sabotage any weight loss efforts.”
It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement.
If you drink regular, go to 2%. If you already drink 2%, go down another notch to 1% or skim milk. Each step downward cuts the calories by about 20 percent. Once you train your taste buds to enjoy skim milk, you’ll have cut the calories in the whole milk by about half and trimmed the fat by more than 95 percent. One disclaimer: There are times when fat-free dairy isn’t the best option.

"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
