How Many Calories Should I Eat?
Gaining weight requires a calorie excess. Depending on your current metabolic rate, activity levels (and other factors including hormones), this amount will vary from person to person.
Begin with this amount and monitor your weight week-by-week. If you are not gaining, then you will need to boost your food intake until you see gains.
As you gain weight, you will need to re-calculate your calorie needs as a high weight means more calories are burned every day!
Having Trouble Gaining Weight?
You are not alone! Read on for some good places to get help.
Some writers refer to you as a hardgainer - you do the same exercises and eat the same as your friend. He puts on muscle, and you gain nothing.
We recommend avoiding muscle building magazines. Most present a very false and unrealistic representation of the hard work and discipline it takes to gain weight. A number of magazines are owned by supplement companies - which makes some of these publications one big glossy ad for the supplement of the month.
Supplements can play a role - but the basis of weight gain is food - not pills and potions.
Only the genetically superior will gain pure muscle mass without any fat (and often this can occur with weight training beginners - called "beginner gains").
The average person will gain fat alongside muscle - this can often only be monitored by measuring body fat percentage against weight.
Some believe that more protein may be beneficial if more intense training is carried out - but this is a controversial point and many bodybuilders often consume too much protein.
How is This Calculated?
All calculators only serve as a guideline or starting point. This weight gainer will estimate your current daily maintenance level and add a percentage of calories to the total.
There are many opinions as to what constitutes the best macro-nutrient levels. However it is commonly agreed that increased amounts of protein are helpful if doing strength training. This calculator will try to provide nutrient levels for quality gains.
Protein is calculated at 1.1 gram per pound of body weight. Fats will come in at 30% of total daily intake. The remainder is made up of carbohydrates. If you struggle to get enough protein into your body from your diet try using whey protein. This is taken in shake form and can be had at any time throughout the day.
