Unsurprisingly, the results showed that nothing had happened to the weight of the women receiving calcium or the placebo. However, the group which took the multivitamin lost more weight – about 3 kg more – and improved their health markers. Among other things, their basal metabolic rate (the rate at which the body burns calories when at rest) increased.
Carb crazy? Consider this: Refined carbohydrates, such as bread, potatoes and rice, create a surge in insulin that in turn drives down your resting metabolic rate, explains Aronne. "It's important to keep carbohydrates in your diet, but really focus on fruits, vegetables and whole grains, which have less of an effect on insulin levels," he explains. And when buying whole-grain breads and cereals, make sure the first ingredient listed is whole wheat, whole oat or cracked wheat.
A study from Canada’s McMaster University (partly funded by Dairy Farmers of Canada) put women on several different diets (lower protein, low dairy; lower protein, medium dairy; higher protein, high dairy) and found they all lost the same amount of weight — but that the higher-protein, high-dairy group lost the most belly fat while also gaining and holding onto the most muscle mass. “It seems… increasing calcium and protein in the diet may help to further promote loss of fat from the worst storage area in the body,” said Andrea Josse, lead author of the study.
That’s not to say you won’t run into tough times in your weight-loss efforts. Any new eating plan is hard to adjust to, and your brain resists change, which doesn’t help matters. Still, the most successful diet is one that you can stick with long-term. Read on for weight-loss tips and tricks to help you get past the hard times and keep your new diet plan on track.
Research also shows that workouts involving high-intensity interval training (HIIT) can help reduce excess fat around your middle. Besides working your core, try incorporating a day or two of more vigorous exercise into your weekly schedule. (You can start with these three beginner routines.) Keep in mind that you can lower your total body fat percentage even by moving around more at work, according to another study.
Carbohydrates are extremely important to training since they are the primary fuel source for working muscles. During weight training the body uses ATP for energy. ATP is replenished through something called the glycolytic pathway. This pathway converts glucose into ATP. Glucose (carbohydrate) is obtained from the bloodstream or from carbs stored in the muscle tissue as glycogen.
Do more HIIT: High intensity interval training (HIIT) is as close to a magic pill as we have (except it involves a whole lot more work than just swallowing a capsule—sorry). Not only does it surge your body to max intensity during the workout, but because you’re working so hard, your body can’t deliver enough oxygen in the moment, explains personal trainer Jeremey DuVall. Your muscles accumulate a “debt” of oxygen that then has to be repaid post-workout. This throws your body into a phase of fat burning for hours after you’re done sweating, known as post-exercise oxygen consumption, or EPOC. Plus, super intense circuits like this activate muscle-building hormones like growth hormone and IGF-1, he adds.
