I’m on a diet!” This is what we usually hear from  people who want to lose weight. But what diet is effective in losing  weight? Starvation diet is definitely a No! No! Our body needs food to  produce energy so we can do our daily activities. The nutrients we get  from food including fats and carbohydrates are important in maintaining  the physiologic function of the body. However, these nutrients become  bad for the body when they are taken in excess. The nutrients, if not  converted to energy are stored in the body as fat deposits, thus the  appearance of the undesirable belly fat and love handles. A balanced  diet comprising all these nutrients as well as protein, vitamins and  minerals, and calcium should be supplied to the body through the food we  eat. This article shares some weight loss diet tips for men and women  of all ages 
The role of fat in a weight loss diet
Fats are an essential food nutrient because they  provide twice the amount of energy than carbohydrates and proteins, and  they help in protecting body organs and tissues and maintaining the body  temperature.
Fats= 9 calories
Carbohydrates= 4 calories
Protein= 4 calories
CAUTION: Too much fat can be very harmful to the  body. Excess fat do not only form the bulges on your body but it could  also clog the arteries of the heart causing myocardial infarction or  heart attack.
What is a low-fat diet?
Low- Fat diet has been promoted by the US Department of Health since the late 1970’s. But what does low- fat diet really mean?
Basically, there are three types of fat: The  Saturated fat which is the Bad fat because it increases the blood  cholesterol level, The Polyunsaturated fat that decreases the blood  cholesterol level, and the Monounsaturated fat which decreases the Low-  density Lipoprotein (LDL) cholesterol or the “bad cholesterol”.
Low- fat diet means: decreasing the consumption of  food that contains saturated fat while increasing the consumption of  food that contains polyunsaturated and monounsaturated fat. Food like  most meat and dairy products, butter, and tropical oils such as coconut  oil and palm oil should be avoided as they are high in saturated fat.  Polyunsaturated fat are usually found in plant food sources such as  corn, soybean, safflower, and sunflower. Food sources for  Monounsaturated fat includes olive oil, peanut oil, canola oil, and some  fruits like avocado.
Carbohydrates are bad or good?
Carbohydrates provides real-time energy in the body  and should account for 50- 60% of the total calories we take in  everyday. However, with sedentary lifestyle, the calories you get from  carbohydrates that are supposed to be converted to real-time energy are  stored as fat deposits, thus you gain weight.
Low –carb diets are among the most popular weight loss diets. There are many variations like:
The Anabolic Diet which alternates low carb and periods of high carb eating
Carbohydrate addicts which serves 2 meals with no carbs and 1 meal of 1/3 carb a day
Ketogenic Diet which eliminates carbohydrate  completely and compensates the caloric need with high fat and moderate  protein intake.
But as per definition, having less than 50-60% of  carb ratio in a serving is low carb diet. If your goal is to maintain  your current weight, do take in moderate carb which is about 40-50% carb  in your diet. And if you want to lose weight, you may go with low- carb  diet which contains 25-39% carb. Lower than this is not really  recommended as it could cause conditions like ketosis, presence of  ketone bodies in the blood. Very high ketone level can make the blood  acidic and may damage organs like the liver and the kidneys.
Some weight loss diet tips that can help eat healthier are:
Instead of eating ice cream, have a low fat yogurt or sherbet.
Use skim milk (fat- free milk) instead of whole milk.
Instead of eating pasta alfredo (white sauce pasta) eat pasta marinara (red sauce pasta).
You may substitute bacon with lean ham.
Since the American Heart Association recommends  avoiding coconut oil because it contains 85- 90% saturated fat, use  olive oil or canola oil when cooking food.
Chocoholics may eat dark chocolate which is rich in anti-oxidant rather than a milk chocolate.
Use beef loin instead of brisket
Instead of white bread eat whole grain bread such as wheat bread
Snack on Peaches (61 calories/pc.), blackberries (62  calories/serving), and carrot sticks (52 calories/cup) instead of fried  chips.
Being overweight or obese doesn’t only place a  person at risk from developing diseases like diabetes, respiratory  diseases, cancer, osteoarthritis and cardiovascular diseases but it  could also affect one’s emotional and social life. People who are  overweight and obese could suffer from low self-esteem, depression, and  impaired body image. Because of this, more and more people are being  conscious of their weight. Losing weight is a tough challenge; you must  be really committed as lifestyle changes should be made.
