how many calories should I consume every day? This is the biggest concern of every dieter. In fact, we can use a simple formula to calculate, that is, multiply our existing weight by 24, and we can know the minimum number of calories we need every day. For example, if you weigh 55 kilograms, you need at least 132kcal of calories every day. The results of scientific investigation show that calories below 12kcal per day will reduce the resting metabolic rate by 45%, which is not conducive to weight loss. While ensuring the normal daily intake of calories, you can choose low-calorie foods. The calories of a cake for your breakfast are 347 calories (1g), and the calories of 1g yogurt are 72 calories [yogurt (medium fat) 1g 64 calories, yogurt (high protein) 1g 62 calories, yogurt (defatted) 1g 57 calories, yogurt (orange defatted) 1g 48 calories, and fruit yogurt 1g 67 calories]. Recommended menu for low-calorie nutrition: breakfast: a slice of whole wheat toast (4kcal)+ fried eggs on one side (75kcal)+ a cup of Gatorade (5kcal) for lunch: a dish of Yu Zi tofu broccoli (26kcal)+ a half bowl of yellow croaker noodles (13kcal)+ a cup of Gatorade (5kcal) for dinner: six sushi.
