calories that i should eat
Women should not consume less than 1,200 calories a day, Brownell cautions. In fact, a diet below 1,000 calories a day (called a very low-calorie diet or VLCD) increases your risk for gallstones and heart problems and should be followed only by obese people under a doctor's supervision. While you can drop to 1,200 calories per day and survive, doing so is not a smart idea.
According to the formula, a 25-year-old man who exercises 30 to 60 minutes every day with moderate or vigorous activity should eat about 2,800 calories a day, while a sedentary 65-year-old woman needs just 1,600 calories.
