There are a range of reasons for a loss of appetite, including being over-tired or stressed and having a cold or taking medication, both of which can dull your taste buds and turn you off your food, according to NHS Shetland, a Scottish health care provider. Simple changes to your diet can help increase your appetite; however it is essential that you seek medical advice if your loss of appetite persists and/or you suspect it is caused by a more serious underlying medical condition.
Eat breakfast. A healthy breakfast is necessary to kick start your body after it has been without food overnight, says the U.K. Foods Standards Agency. For best appetite-enhancing results, include a variety of fruits, yogurt and wholegrain cereals. Think of your body as an engine: it needs good-quality fuel, or food, to function properly and, by burning this fuel, you use up energy, which makes you feel hungry again.
Eat little and often. Big meals take your body longer to digest and can make you feel bloated and lethargic, which means you are less likely to feel hungry, reports the U.K.'s "Daily Mail" newspaper. By eating small meals regularly throughout the day, you will make it easier for your body to digest the food and burn it as fuel. And with your body burning smaller amounts of fuel more often, you are likely to feel hungrier sooner.
Eat less fiber in your diet. As a short-term solution, try eating fewer fiber-rich foods, such as brown rice and bread, pasta and oats. Fiber is an essential part of a healthy diet, but if you need to increase your appetite quickly, slightly reducing your intake can make you feel hungry more often. A high-fiber diet makes you feel full for longer because it is processed slowly by your body. It also slows the rate at which food enters your bloodstream and is used up as energy.
