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.
In reality, a never-ending list of factors—including (yes) food and exercise, but also sleep, stress management, hormone health, self-esteem, past weights, and those pesky genetics—influence weight loss as well as the weight your body naturally gravitates toward at a given time in your life, Abby Langer, R.D., a Toronto-based dietitian and nutrition counselor, tells SELF. Of course, maintaining a caloric deficit drives weight loss, but so much more goes into a successful weight-loss effort than the math of calories in and calories out.
You should already be following a diet to get lean, and should therefore be aware of how much you’re eating. But to remove any guesswork, we’ll give you some numbers to hit for the week: Consume one gram of protein and 10–11 calories for every pound of your body weight; 20% of those daily calories should be from fat, and the remainder from carbs. (Remember to first subtract the protein calories you’re also eating from the total allowed before you calculate the number of carbs.)
If you want to lose weight you should start by avoiding sugar and starch (like bread, pasta and potatoes). This is an old idea: For 150 years or more there have been a huge number of weight-loss diets based on eating fewer carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
When the going gets tough (and it likely will from time to time along any weight loss journey), it’s important to realize that a host of non-food factors can make losing weight difficult, explains board-certified obesity medicine specialist Spencer Nadolsky, D.O., a diplomate of the American Board of Obesity Medicine and author of The Fat Loss Prescription. Hormones, genetics, and, ultimately, metabolism are three big ones, he says.
“We try not to vilify any food, except sugar,” added Dr. Aronne. “Having it as a treat is what sugar is for; it’s not meant to be the main part of your meal.” Yet added sugars in the form of sweeteners and syrups to flavor processed foods sees the average adult eating 20 teaspoons of hidden added sugar every day, or an extra 320 calories, according to the USDA’s recent nationwide food consumption survey. And then there’s sugar-sweetened beverages like sodas, sports drinks, juices and flavored coffees and teas stirred with empty calories. “The typical glass of orange juice has three oranges in it; that’s the calories of three oranges. But it’s easy to drink a glass of orange juice and still eat a number of other things,” added Dr. Aronne. “You’re better off just eating a single orange and feeling full.”
Belly fat is, in fact, the colloquial term for abdominal fat. According to medical experts, belly fat can be potentially dangerous. Excess of it can lead to a number of health problems including heart diseases, high blood pressure, type 2 diabetes, a decrease in the level of HDL or good cholesterol, and can even lead to strokes or sleep apnea. You need to combat this problem before it gets too late.
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
