In a new study, Stanford University researchers put more than 600 overweight adults on either a healthy low-fat or low-carb diet. It turns out, participants had similar levels of weight loss success on each plan. Researchers looked for clues (such as insulin levels and gene patterns) to see if there are any factors that might make someone more successful on either diet, but after combing through the data, they were not able to make any connections. Since it may take years before scientists discover individual traits that could lead to more success on one plan compared to another, for now, we can learn a lot — and lose a lot! — by recognizing the dieting advice that all experts agree on.
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
If you're trying to lose pounds, your IBW is your goal weight; for maintenance, your IBW is your current weight. For instance, if you weigh 135 pounds and you want to maintain that, you need about 1,890 (135 x 14) calories per day. This is a very rough calculation; for a more accurate assessment, have your metabolic rate tested by a fitness professional.
When you're at your heaviest, it can be intimidating to step into a gym and begin running or lifting among the spandex-clad. Working out in your own space is also simply easier to schedule—you can lift weights while the baby naps or first thing in the morning without dragging yourself out the door. "I bought an exercise bike so I can work out whenever I want," says Sarah DeArmond, who lost 100 pounds.
Type of support: Every person has different needs when it comes to what motivates them to succeed. Think about how you have met other important goals, quit bad habits, or motivated yourself to change in the past. Would you be more likely to succeed using social media; in-person meetings with strangers or acquaintances; or expert counseling using text messaging, phone calls or email?
Sodas and juices are essentially liquid candy: They contain up to 18 teaspoons of sugar and upwards of 240 calories per 20-ounce serving, and provide zero nutritional value. Experts point to soda as one of the top contributors to the obesity epidemic. Diet drinkers aren't off the hook, either. A study in the journal Obesity found that diet soda drinkers were more likely to have a high percentage of fat in their bellies. Researchers believe diet drinkers may overestimate the calories "saved," and then overeat.
The Academy of Nutrition and Dietetics (AKA the top nutrition authority in America) released a revised paper this year saying that both vegetarian and vegan diets are best for people's health as well as the environment. If you're not ready to make a complete shift to meatless and cheese-less, consider "part-time" vegan and vegetarian plans, where you eat mostly plant-based at breakfast and lunch or on weekdays, and then eat fish, meat, dairy, and eggs only during designated times.
