EFAs stand for Essential Fatty Acids. Just as the name implies EFAs are essential to the human body because play a role in many different biological processes. Essential fatty acids differ from others fats in that they cannot be synthesized within the human body. This means that EFAs must be consumed through the diet. If not enough EFAs are consumed the body will sense that it does not have the nutrients that it needs to function properly. As a result it will essentially “hold on to” body fat. This is just one of the reasons EFAs are so important though.
REALITY: Fats and carbs both play a role in fat loss. Fats are responsible for hormone production, joint lubrication, and many other important health and muscle-building factors. Dropping your fats too low could compromise your health and your goals. Everyone's body and metabolism is different, so it's crucial to know how many grams of healthy fat you need to eat for a balanced nutrition regimen.
Do this: Fifteen to 30 minutes (or less) before training, consume 20g of protein powder in a whey shake or other protein powder source and 30-40g of carbohydrates to help you train hard all the way through your workout. Stick with slow-digesting carbs here, such as oat bran, oatmeal, rye or whole-wheat bread, fruit, or sweet potatoes. On nonworkout days, eat that meal as a snack and drop your post-workout feeding.
The meals shown here are "templates" that you can vary any number of ways to please your tastebuds and avoid eating the same old thing every day. Follow them and you'll get between 2,400 and 2,800 calories per day. That should provide plenty of calories for all but the most severely obese, while allowing most guys to lose fat around their middles at a steady pace. (Don't worry about hitting the numbers on the nose every time. If you exceed your fat quota during lunch, for instance, just cut back a little during dinner.)
There’s one thing to like about visceral fat: It yields fairly easily to aerobic exercise. Vaporizing calories via running, biking, swimming—anything that gets your heart rate up—is an effective way to whittle your middle. In fact, one 2011 study from Duke University Medical Center, published in the American Journal of Physiology, found the sweet spot: Jogging the equivalent of 12 miles a week was even more effective in reducing visceral fat than resistance training three times per week. However, both types of exercise were beneficial when it came to belly fat, the researchers say. (Don’t have time to hit the gym? Try these fun at-home cardio workouts if you’re in a pinch.)
Weight loss occurs when the body is expending more energy in work and metabolism than it is absorbing from food or other nutrients. It will then use stored reserves from fat or muscle, gradually leading to weight loss. For athletes seeking to improve performance or to meet required weight classification for participation in a sport, it is not uncommon to seek additional weight loss even if they are already at their ideal body weight. Others may be driven to lose weight to achieve an appearance they consider more attractive. However, being underweight is associated with health risks such as difficulty fighting off infection, osteoporosis, decreased muscle strength, trouble regulating body temperature and even increased risk of death.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
