Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss. For athletes seeking to improve performance or to meet required weight classification for participation in a sport, it is not uncommon to seek additional weight loss even if they are already at their ideal body weight. Others may be driven to lose weight to achieve an appearance they consider more attractive. However, being underweight is associated with health risks such as difficulty fighting off infection, osteoporosis, decreased muscle strength, trouble regulating body temperature and even increased risk of death.
Many restrictive diets result in fast weight loss because of the lack of carbohydrates. Why does this work? “It’s all about water weight," says Dietitian and BDA Spokesperson Chloe Miles. “When you eat carbohydrates, your body stores it as glycogen in the liver and muscle. Your muscles store approximately 500g and your liver approximately 100g and it’s thought that every gram of glycogen in the human muscle is bound to 3g of water,” she says.

If you’re logging just a few hours of sleep a night, you may actually find yourself gaining weight. Researchers at the University of Chicago Medical Center found that subjects who slept just four hours had a harder time processing carbs. "When you're exhausted, your body lacks the energy to do its normal day-to-day functions, which includes burning calories efficiently," says Talbott.
This was one of the biggest challenges for me. That said it is crazy how fast you can lose weight quickly if you simply cut out drinking unnecessary calories. Admittedly, I’ve historically enjoyed a beer or two over dinner at home – and even more than one or two if out with some friends. Although I don’t think there’s anything wrong with a beer a night, or a glass of wine a night, I know the former is not great for losing weight.
Get to know the Glycemic Index (GI). It rates carbohydrates according to their effects on blood sugar. Carbs are ranked on a scale of one to 100+ (glucose is 100). Low-glycemic foods, as you would imagine, have a lower number. This means they do not spike your blood sugar, and are generally healthier for you. High-glycemic foods have a higher number; they quickly elevate your blood sugar, and are not as healthy for you. In general, I like to stay with foods that have a GI rating under 60.
That said, carrying extra weight around the middle is also tied to increased heart risks, making it arguably unhealthier to be an overweight man than a plus-size woman. Big bellies, it turns out, are a sort of a double-edged sword when it comes to weight loss: They're an extra health risk for men, but give guys the edge when it comes to dropping pounds.
One easy trick if you're a pasta fan is to swap out white pasta for the wonderfully named courgetti (spaghetti made from spiralizing courgette). You’ll hardly notice the difference when you’re eating it, but you’ll be fuller for longer despite consuming fewer calories. When you consume fewer calories, your body can go to your fat reserves for energy, rather than just burning off the food you’ve eaten.
A commonly overlooked obstacle to eating better (and losing weight) is sleep. While sleep needs vary, according to the National Sleep Foundation, adults require seven to nine hours a night. Unfortunately, two-thirds of people report experiencing sleep problems at least a few nights a week, with women more prone to sleep problems than men. A review study that looked at 36 studies on sleep and weight gain found short sleep duration was independently linked to weight gain. Studies show the fewer minutes you spend asleep, the more likely you are to feel hungrier and make poor food choices the next day. Make sure you’re getting enough Zzzzs to reap the rewards of your weight loss efforts.
Why do people get different results with this diet plan? Medical conditions can play a big role in weight gain or loss. It is important to understand any medical conditions you may have before going on a diet. Many different issues can lead to abnormal weight gain, including thyroid issues. If this is a concern for you, read this article on hypothyroidism and its effect on weight. Mental health issues can also lead to weight gain or loss. If you struggle with anxiety, you may experience abnormal weight gain. Make sure to ask your doctor for advice about how to manage the anxiety without over-eating.
But it's important to remember that "fat" doesn't mean "unhealthy." Yes, women have larger fat stores, but it's part of their physiology, meaning it's not extra weight. So if a woman has 11 percent more body fat than a man, it doesn't mean she's 11 percent "fatter." A perfectly fit woman will still hold six to 11 percent more body fat than a perfectly fit man.
