We often make the wrong trade-offs. Many of us make the mistake of swapping fat for the empty calories of sugar and refined carbohydrates. Instead of eating whole-fat yoghurt, for example, we eat low- or no-fat versions that are packed with sugar to make up for the loss of taste. Or we swap our fatty breakfast bacon for a muffin or donut that causes rapid spikes in blood sugar.
Carbohydrates are the preferred form of fuel for your body's energy needs. Simple or sugary carbs have their place when you need fast energy, but for the most part you should eat complex or slow-burning carbs (we'll give you examples of these later). The thing about carbs, though, is that after you consume all the carbs your body needs for immediate energy, any excess carbs will be stored as body fat.
The Centers for Disease Control and Prevention suggests subtracting 500 to 1,000 calories from your usual intake each day to lose at a healthy rate. First, keep a food diary to estimate the number of calories you currently eat, then subtract the calories to determine your weight-loss calorie needs. For example, if you currently eat 2,300 calories a day, to lose 1 to 2 pounds a week you need to reduce your intake to 1,800 calories or 1,300 calories a day, respectively.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
The idea is that the fasting induces mild stress to the cells in your body, helping them become better at coping with such stress and possibly helping your body grow stronger. The verdict is still out regarding the diet’s long-term effectiveness with weight loss, according to a review of preliminary animal research published in January 2017 in Behavioral Sciences. (17)
Five different Medifast plans plus one meal of lean protein and non-starchy vegetables will give you a loss of about 11 pounds in eight weeks, according to the company. Although these very low-calorie diet plans are effective in the short term, weight regain is a risk over the long haul. It also depends on processed foods and requires dieters to last through the hunger pangs. The plan is not recommended if you are pregnant, have type 1 diabetes, or have any of these other conditions. Here are 17 tips for getting over a weight-loss plateau.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
While 1,200 may be the right number for some, it can be super restrictive for others, says Jaclyn London, MS, RD, CDN, Nutrition Director at the Good Housekeeping Institute. Try basing your meals and snacks off this plan and double up on veggies at any opportunity — more fruit at snack time works too! You can also add an extra ounce or two of protein at all meals if you find yourself feeling hungry. The combo of fiber from produce and lean protein makes this an adaptable strategy that’ll help you lose weight safely — one meal (and snack) at a time!
