Reducing your total body fat not only helps you lose weight, but also can have significant improvements on your health. Lowered risk of heart disease, diabetes, hypertension and sleep apnea are just a few benefits of losing excess fat. When you're trying to lose weight, it's ideal to lose only excess fat. However, without proper planning, dieting can also lead to the loss of lean muscle mass. While you'll see a reduction in your overall weight, losing muscle mass may lead to weakness, fatigue, poor athletic performance, and decreased metabolism. A well balanced diet can help you lose excess fat mass, minimize muscle loss and improve your overall health.
‘If your body fat gets too low, your body will need to find alternative energy sources – and will start to eat your muscles.’ How to tell if you’re teetering on the edge? ‘You’ll feel tired, headachey and weaker in your workouts – watch out for not being able to lift as heavy as you used to. It could be a sign that you need to put some fat back on.’
Talk about a catch-22: Doing something healthy, like eating a low-cal meal, can make you less likely to exercise and more likely to gorge yourself with food later on. This is because of a phenomenon scientists call licensing, which happens when we feel that we've earned the right to be self-indulgent. Most people have a tendency to want to balance things out, says Kathleen Vohs, Ph.D., an associate professor of marketing at the Carlson School of Management at the University of Minnesota. So when we do one thing that's good for our health, which often requires exerting plenty of discipline and self-control, we like to follow it up with something that lets us indulge ourselves.
To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
The Atkins diet web site states the current plan "is about eating delicious and healthy foods, which makes it so much better than any of those fad diets out there. You eat a variety of your favorite foods -- lean protein, leafy greens, vegetables, nuts, fruits, whole grains. Plus, you get delicious Atkins bars and shakes from day one and every step of the way."
The scale is not necessarily your friend. You may want to lose fat – but the scale measures muscles, bone and internal organs as well. Gaining muscle is a good thing. Thus weight or BMI are imperfect ways to measure your progress. This is especially true if you’re just coming off a long period of semi-starvation (calorie counting), as your body may want to restore lost muscles etc. Starting weight training and gaining muscle can also hide your fat loss.
The best diet for losing weight is Weight Watchers, according to the experts who rated the diets below for U.S. News. Volumetrics came in second, and the Flexitarian Diet, Jenny Craig and the vegan diet were third on this overall weight loss ranking list, which takes into account short-term and long-term weight loss scores. Some other diets performed as well or better in our rankings for enabling fast weight loss, but long-term weight loss is more important for your health.
But just because belly fat comes off a bit more easily doesn’t make it less dangerous. In fact, it’s the exact opposite. “Belly fat is unfortunately the most dangerous location to store fat,” says Dr. Cheskin. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it’s more active in terms of circulating in the bloodstream. That means it’s likely to raise the amount of fat in your blood (known as blood lipid levels) and increase your blood sugar levels, which as a result raises your risk of heart disease and type 2 diabetes.
“Intermittent fasting can be really challenging if you have an ever-changing schedule,” adds Hultin. “If you're traveling and crossing time zones, it could be very difficult to follow. It might be best for people with more stability in their lives.” Intermittent fasting isn’t safe for people with type 2 diabetes, children, pregnant or lactating women, or anyone with a history of an eating disorder.
If you eat fewer calories than you burn, you'll lose weight. But when you're hungry all the time, eating fewer calories can be a challenge. "Studies show people who eat 4-5 meals or snacks per day are better able to control their appetite and weight," says obesity researcher Rebecca Reeves, DrPH, RD. She recommends dividing your daily calories into smaller meals or snacks and enjoying most of them earlier in the day -- dinner should be the last time you eat.
So best stock up on protein-enriched products then? ‘Supplements should only be used if you can’t meet your targets through a healthy, balanced diet alone,’ Vine says. ‘The more nutritious sources of energy you feed your body with, the more it will want to use them – meaning your training will improve, you’ll burn more calories and build more muscle, and you’ll lose more body fat.’
