1. Eat High-Fiber Low-Glycemic Foods
Low-glycemic foods are carbohydrates that breakdown slowly, releasing sugar into the bloodstream gradually rather than all at once. These foods almost always contain fiber. The fiber is what is mostly responsible for slowing the absorption of the sugars. These foods can provide long-lasting energy. Most vegetables (especially dark green), most fruits, whole-grains and nuts are high-fiber, low-glycemic. For optimal health, get your grains intact from foods such as whole wheat (whole-grain) bread, brown rice and other possibly unfamiliar grains like whole oats.
An Indian adult should acquire 1,600 calories a day through his diet while a woman should get at least 1,400 calories. Recommendations say less than 25% of our diet should be fat.
However, when we consume just 10 pieces of chips, we take in 4 grams of fat that translates to 36 calories.
2. Eat More Protein
Your body requires more energy (calories) to process protein than it does carbohydrates. Eating more protein can increase your metabolism, thereby increasing your body's ability to burn fat. Protein is necessary for your body to build muscle, and building more muscle increases your ability to burn fat. Good options include eggs, low-fat or no-fat dairy products, lean meat, poultry, seafood and whey protein supplements. Nuts and legumes are also excellent sources of protein; plus you get the added benefit of fiber, vitamins, and minerals. Legumes include black beans, red beans, pinto beans, navy beans, garbanzos, and other beans that are usually sold dried.
3. Eat Frequent Small Meals Throughout The Day
Eat 6 smaller meals per day, rather than 2-3 larger meals. This will ensure that you will supply your body with the necessary nutrients to build muscle and burn fat while increasing your metabolic rate. It will also supply a constant stream of energy to prevent fatiguing early and prevents the body from kicking into starvation mode. If this happens, your body will burn muscle for energy increasing your body fat stores as well as slowing down your metabolism.
4. Eat Balanced Meals
Make sure you cover veggies, milk, smoothies, beans, brown rice, whole-wheat, fruits, nuts, whole-grain cereals, yogurt, etc in your day meals. Balance your meals by making sure that you eat plenty of protein and fiber in each meal.
5. Never skip BREAKFAST
This is the one meal you cannot afford to miss! Jump start your day with a high-fiber, high protein meal containing complex carbohydrates, avoiding simple (sugary) carbohydrates which trigger hunger and sleepiness a few hours later. Choose whole-grain cereals that are loaded with fiber and protein instead of sugar (Oatmeal, etc). Fat-free milk or soy milk and sliced almonds. Smoothies are great for breakfast too!

Basic Nutrition Strategies
Metabolism
Metabolism is processes within the body that convert food and other substances into energy and other metabolic byproducts used by the body. The process of metabolism is really a balancing act involving two kinds of activities that go on at the same time — the building up of body tissues and energy stores and the breaking down of body tissues and energy stores to generate more fuel for body functions. Metabolism is a constant process that begins when we're conceived and ends when we die.
Your fast metabolism can quickly slow down with age. Diet can have an extreme impact on your metabolism. Certain foods can either slow down your metabolism and make your body gain weight or it can speed up your metabolism and help you burn calories and fat. Junk food can also slow down your metabolism so if you want to keep your fast metabolism you should start eating healthy. An easy way to do it is to make your own juices and smoothies!!
Exercise has a major effect on your metabolism. The more you move the more your heart has to pump to keep the right nutrients in your muscles. This has a great effect on your body's ability to burn calories (energy metabolism). Any type of exercise effects metabolism in a positive (increasing) fashion.
How can you boost metabolism?
Strength training (otherwise known as resistance training) is another way to boost your metabolism. This can be done with light weights and a high number of repetitions, or a higher intensity lifting with fewer repetitions, both working on large muscle groups. The result will be the same - more muscle mass which translates into a higher metabolism.
Do you put on more weight when you eat late at night?
I read the following on the web. Not sure how much truth is here and what to believe.
Eating food in the hours just before bedtime may need to be avoided. Any calories consumed in the evening will count more. They usually cite the "fact" that a person's metabolism slows down significantly in the evening, or that no one burns calories in the middle of the night. Your metabolism is completely shut down in the midnight. Any fruit contains natural sugar which will not be processed until 7AM at which your biological clock wakes up and starts digesting again.
When we consume fried food late at night, the digestion process takes place constantly within us, seriously affecting our sleep. A person should hit the bed at least three hours after the last meal. Fried food late at night also leads to acidity that again hampers sound sleep and adds to your body weight.

Gym mistakes you must avoid
Staying fit is the one of the biggest challenge. Researchers consistently recommend that regular physical activity with healthy eating habits is the most efficient way to keep yourself fit and control your body weight.
Weight training is common type of strength training for developing the strength and size of skeletal muscles. Weight training tones your muscles which raises your basal metabolism which causes you to burn more calories 24 hours a day. Weight training uses a variety of specialized equipment to target specific muscle groups.
We can use weights typically in two ways:
1. Free Weights (including barbells, dumbbells, and hand weights)
2. Weight Machines
But, weight training carries a certain risks so make sure you follow the things mentioned to below to avoid those risks.
Why stretching in the Gym is important
Before you try any of the gym facilities, you need to warm up. Stretching improves your muscles' range of motion and helps keep them long. During a weight-training session, you should utilize the time between the sets by selective muscular stretching. Although many people regard stretching only as a means to increase flexibility, it can provide muscular benefits when incorporated into your routine. Stretching a "pumped" muscle can actually enhance the quality of your workouts and even help to promote muscular growth. Selective muscular stretching helps to neutralize the effects of lactic acid by restoring blood flow to your working muscles.
warm up and cool down
The purpose of a warm-up is to prepare your muscles for a workout by raising your body temperature slightly and making your muscles more pliable.
Simply walking on the treadmill or doing the cycle at a low to moderate speed for 5-10 minutes ensures a good warm up. Similarly, never forget to cool down after a workout by stretching the various muscles of your body. This will help bring your heart rate and body temperature back to normal.
Wrong postures/ techniques
If you are doing an exercise standing up -- like a bicep curl, for instance -- make sure you stand with your feet apart for better balance. Never lock your joints while performing an exercise.
Too fast or too slow
Whether you are doing a squat or a bench press, make sure you do your exercise at an even pace. You should be lifting and lowering the weight at approximately the same speed throughout the workout. This will ensure you do not get injured and, at the same time, see to it that the tension on the muscle stays constant.
Too intense
Try to mentally rate your exercise on a scale of 0-10 by the end of each set, with 10 being the toughest. If you find that you are rating the intensity at five or six even in the last set for each muscle, you need to up the intensity.
Too long
An ideal workout should last you about 45-50 minutes. If you train beyond this time span, you are either doing more than required or you are wasting too much time in between the workout, which menas you won't get the results you want.
The same old routine
It's a good idea to change your workout routine every six weeks to prevent your muscles from getting used to the exercises. Change the repetitions or weights you lift, do a different set of exercise for each muscle or switch to a different activity. You will be surprised at the change in stamina.
You don’t time your rests between sets
Your recovery time is important when looking at how much you are going to be able to lift later on. ‘Too short a rest and your muscles won’t have recovered; too long and you won’t get the benefit.’ Wear a stopwatch and don’t be intimidated into starting your next set too early.
You only ever use heavy weights to build muscle
When you hit the weights room, you always lift the heaviest weight possible. This may limit your growth because you’ll hit your muscles in a very predictable way, and it’s hard to control large weights precisely. Now and then, go light and do extra reps with a greater range of motion.

Types of exercises : anaerobic and aerobic
There are two types of exercises: anaerobic and aerobic.
Anaerobic exercise
The term "anaerobic" means "without air" or "without oxygen."
The term "anaerobic" means "without air" or "without oxygen." Anaerobic exercise uses muscles at high intensity and a high rate of work for a short period of time. Anaerobic exercise helps us increase our muscle strength and stay ready for quick bursts of speed. Think of short and fast when you think of anaerobic exercise.
Examples of anaerobic exercise include heavy weight lifting, sprinting, or any rapid burst of hard exercise.
Anaerobic exercise is usually performed at high intensity and can be sustained for periods of time as short as 10 seconds. During a sprint, the muscles need for oxygen cannot be matched by faster breathing and increased pumping by the heart. The muscle then turns to making energy through a non-oxygen dependent mechanism. The by-product of that is called lactic acid. The lactic acid triggers muscle aching and burning. After finishing the run, the lactic acid is slowly converted to a different non-troubling product, as the oxygen debt is paid back. So these anaerobic exercises cannot last long because oxygen is not used for energy and a by-product, called lactic acid, is produced.
Lactic Acid contributes to muscle fatigue and must be burned up by the body during a recovery period before another anaerobic bout of exercise can be attempted. The recovery period also allows the muscles to use oxygen to replenish the energy used during the high intensity exercise.
Aerobic exercise
Lower intensity activities performed for longer periods of time. Activities like walking, jogging, swimming, and cycling require a great deal of oxygen to make the energy needed for prolonged exercise. Both aerobic and anaerobic exercises are needed for the development of physical fitness.Aerobic exercise on the other hand is done at a pace that does not outstrip the muscles ability to get the needed oxygen. Apart from the effects of dehydration, fatigue then is due to a lack of glucose. Many athletes have enough stored glucose (called glycogen) for about one to two hours of exercise. After that, the body simply runs out and they "hit the wall."
With regular aerobic exercise, the muscles and liver will increase their stores of glycogen to meet the new demands. Poor nutrition prevents this from happening and will allow these stores to become drained.

Role of "Lactic Acid" in workout/metabolism
Lactic acid is a chemical structure made out of carbon, hydrogen, and oxygen in a chain-like form. Lactic acid is produced as a result of hard work by the muscles. What happens is that when your body is working hard, it produces high levels of lactate in the muscles. When you’re running , your body produces so much lactate that it can’t remove it from the muscles quickly enough.
However, while this sounds like a bad thing, it’s actually a sign that your body is finding ways to create energy and ensure that you can keep doing whatever it is that you’re doing.
Why your "muscles" ache after a work out
When the lactate levels get too high, a chemical reaction occurs with other chemicals in the body, creating lactic acid. What you should know is that it is not the rise in lactate levels that leads to that burning feeling in your muscles, but rather it seems that it is the reaction that forms lactic acid that is the cause of the pain. But some scientists are still debating about the pain’s source.
Several theories have been proposed, to explain the delayed muscle soreness. One theory is intensive exercise and lactic acid accumulation. Some evidence disputes the role of lactic acid, in muscle soreness. For example, lactic acid is removed from muscle, within 30 minutes after exercise, but soreness does not appear for at least 24 hours. Also, some exercises, such as those that stretch the hamstring muscle, cause little, or no lactic acid build-up, but result in soreness.
Another theory, is a tissue damage theory. Considerable evidence supports the idea, that exercise damages muscle fibres and /or surrounding connective tissue (micro-tears). The muscle tissue becomes swollen, which stimulates sensitive nerve endings and results in soreness.
Better Muscular Recovery
Contrary to popular belief, muscle tissue is actually broken down-not built up-during anaerobic exercise. When a muscle is subjected to intense stress, tiny micro tears develop in its fibers. This contributes to the presence of delayed-onset muscle soreness (DOMS) that often accompanies a grueling workout. By expediting nutrient delivery to your musculoskeletal system, selective stretching helps to repair muscle tissue and accelerate the healing process.
How to overcome lactic acid
But what you really want to know is how you can avoid that burning pain when you are working out. And the answer is simple: work out more. While it might seem counterproductive to workout more, what you need to do is effectively ‘teach’ your muscles to handle lactic acid in a more effective way. However, you want to do this is a controlled fashion so that you’re not hurting each time you walk in the door.Once lactic acid builds up, you simply cannot continue to train. Selective muscular stretching helps to neutralize the effects of lactic acid by restoring blood flow to your working muscles.
You can start to build up a resistance to lactic acid by working out at a medium intensity during your workouts. This means that you are working just hard enough to get your heart pumping fast and your lungs working a little harder.
You might measure this by how much you can talk as you are working out – which should be in incomplete sentences, though you can still talk. As you build up your muscular and aerobic capacity, your body will be able to handle higher levels of lactic acid and thus reduce the amount of pain that you might feel.
