Keep in mind that losing weight fast is often not the best way to keep the weight off. You can lose weight quickly by drastically cutting calories (often, starving yourself) but once you stop the low-calorie diet, you’ll gain the weight back. Still, you can see results in as little as 2-4 weeks on a healthy weight loss diet. The key is to not starve yourself, but to instead reach for naturally lower-calorie whole foods that will provide you with nutrients and satiate you. Feeling satisfaction with your diet is key to maintaining it. Combining your whole foods diet with moderate exercise and physical activity (walking, weightlifting, strength training, and yoga) can accelerate weight loss. A slight calorie deficit is helpful for weight loss, as long as you don’t feel tired and hungry throughout the day.
