Weight loss isn’t a linear event over time. When you cut calories, you may drop weight for the first few weeks, for example, and then something changes. You eat the same number of calories but you lose less weight or no weight at all. That’s because when you lose weight you’re losing water and lean tissue as well as fat, your metabolism slows, and your body changes in other ways. So, in order to continue dropping weight each week, you need to continue cutting calories.
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.
Cutting out food groups is not the healthiest weight loss solution. “When you eliminate either fats or carbohydrates, you’re probably eating way too much of what’s left over,” says Kristin Kirkpatrick, MS, RD, manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. For example, if you cut out fat, you could overdo it on carbohydrates or vice versa. Instead, Kirkpatrick recommends balancing your meals and having one whole grain carbohydrate at each meal and opting for low-fat dairy products and lean meats. Here is the worst diet advice nutritionists have ever heard.
