For years, people always think it is a good way to lose weight by eating less. This seems easy, but it turns out that it’s harder than it sounds. However, Emma Brown, a nutritionist（营养学家）says that you can make it by eating 120g of steak, one biscuit and just half a scone（英式茶饼）. Here she explains how much of each food group you should eat each day.

	A portion（一份）of red meat (120g) has 162 calories（卡路里）. Although small amounts of protein regularly throughout the day are good for you, try not to have red meat too often.
	A portion of fish (125g) contains 271 calories. A healthy diet should include at least two portions of fish a week, including one of oily fish.
	A portion of potatoes (235g) should have 172 calories. Emma also advises eating the skin for extra nutrients.
	There are 27 calories in a portion of carrots (80g) and you can eat five portions a day.
	A portion of blue berries (80g) has 28 calories but Emma warns overeating fruit or vegetables can lead to weight gain.
