It is possible to lose ten pounds in a month. As @digitalimpression said, it’s a lot easier to start by cutting unhealthy habits out of your diet. Do you drink soda a lot, eat late at night, eat a lot of sweets? Try replacing unhealthy snacks like chips with healthier alternative like nuts, fruit, veggies, or Greek yogurt. Eat more fish and poultry rather than red meat. Try to eat less pasta and white grains. If you’re having rice, make it brown rice. If you’re having bread, make it whole grain. Add a vegetable to your meals whenever possible. Though people say that fruit is bad because it contains a lot of sugar, it’s a much healthier alternative to sweets and stuff like that because it’s natural sugar, not a lot of artificial flavors and ingredients you can’t pronounce, so I wouldn’t necessarily rule out fruit as a healthy food source.
While it is possible to lose weight without exercising, it’s much easier to lose weight if you exercise. It doesn’t have to be something boring like running on a treadmill, it can be anything that gets you up and moving and breaking a sweat! Try playing a new sport, riding your bike, going for a run outside, or dancing. Do something that you enjoy, and it will make the whole process a lot better. That way, you’re not just losing weight, you’re also getting in shape!
