To make it simple fast weight loss is always followed by fast weight gain. No exceptions. In addition to that when you lose weight too fast, your skin does not have enough time to shrink, it will become loose.

The right amount of weight that average person can lose in one week by eating correctly and doing exercises is around 2-3 pounds. That is a healthy, safe, effective amount to lose. Only that way you can get long lasting results. I know it is not as fast as many people would like to lose weight, but think about it how long did it take you to gain weight? I bet you $1000 dollars you didn't gain 20 pounds in two weeks. It is only logical, that your body will not allow you to lose 20 pounds in two weeks. Sorry!

I'm trying to save your money here, so repeat after me "There is no machine, no special diet, no special workout program, no special pill or special patch that will help me to lose weight fast and healthy at same time". Repeat it to yourself every time you have an urge to buy some "quick fix" no matter how appealing it sounds.

Remember people who have created these commercials are professionals who know what you would like to hear. Don't let them fool you. Just try to eat right and work out. Be consistent. Make one little step at a time and you'll be surprised how far you can actually go.

To build mass, you must weight train with heavy weights. To consider a weight heavy, you should only be able to do a maximum of 4-8 reps before your muscles temporarily fail. A weight is considered 'light' if you can do more than 15 reps before muscle fatigue sets in. Heavy weights stimulate more muscle fibers than lighter weights which result in more muscle growth. Heavy weight training puts a huge strain on your body, so adequate rest and recuperation after your workouts is essential.

Eating guidelines for building muscle:

A high protein diet is an inevitable part of any weight training programme, importantly, protein derived from animal sources. Proteins you need to be concerned with are those found in whey, casein (cottage cheese), eggs, beef, poultry, and fish. Soy protein, tofu and bean curd are some alternatives. Eating right amount of foods consistently will force your body to grow beyond what you may think possible. The diet also should contain an adequate amount of carbohydrates (potatoes, sweet potatoes, yams, oatmeal, cream of wheat, cream of rice, rice, beans, bread, pasta, all cereals) and fat. Green leafy vegetables and fruits also should be included.

When you train with weights, you should eat a minimum of 1 gram of protein per pound of body weight. You also must have protein at every meal. To enable your body to actually assimilate and use all calories you will ingest, you have to reduce your meal size and increase your meal frequency. Splitting your calories into smaller, more frequent portions will enable food absorption and utilization of nutrients.

During past 20 years there have been great developments in scientific understanding of role of nutrition in health and physical performance. Studies shown that adequate dietary carbohydrate should be ingested (55-60% of total energy intake) so that training intensity can be maintained. Excess dietary saturated fat can exacerbate coronary artery disease; however, low-fat diets result in a reduction in circulating testosterone. So balance between protein, carbohydrate and fat should be maintained.

So focus on weight gain programmes must be on two components, lifting heavy weights, which will stimulate largest amount of muscle fibers. Your body responds to this stimulus by increasing your muscle mass and secondly eat more calories than your body is used to. When you overload your system with plenty of protein and fats, your body has no other choice but to gain weight.

A Mass Gaining program is incomplete without timely measurements to monitor your progress. Without it, you won't know how exactly your body is responding to your diet and training routine. Just looking in mirror and guessing is not acceptable. If you want to start getting great results, you must develop habit of accurately tracking your progress. This also provides motivation to continue with weight gain schedule and for further progression. So even though you have a very thin body type, and haven’t been able to gain weight no matter what you try, you will definitely succeed with a well planned weight gain programme.
