Question 1

how many calories deficit per day do i need to lose 2-4 pounds per week with moderate exercise?

Accepted Answer

Exercise: 3500 calories to lose a pound of fat.  500 calories a day is a lot of exercise--- so consuming 500 less calories a day with this should lose 2 pounds a week.

Question 2

why do i need a calorie deficit to lose 20 pounds if the calories needed to maintain my weight is the same whether i weigh 115 or 102 pounds?

Accepted Answer

Weight loss: Your caloric requirement is just a guess- the amount required for a 115 and 102 lb person is different, but not by a whole lot.  The caloric deficit you will need to maintain to lose 20 lbs is way more than the piddly difference between the metabolic requirement.  To lose 20 lbs in 6 months you will need a deficit of about 400 cal/day every day.

Question 3

i limit my food intake to two thousand calories, try to eat as healthy as possible and exercise three to five days a week. however, i can not get below 160 pounds at 56. how, can i change my lifestyle to lose the extra weight?

Accepted Answer

: You need to reduce your food intake to no more than 1200 calories. This will have to be a long term change otherwise you will lose weight and gain it back up as soon as you slacken on your food intake.
For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.

Question 4

how many calories should i consume per day to lose 3 pounds a week?

Accepted Answer

Your basic needs: You can loose that many pounds just by eating what is recommended for you based on your gender, age and physical condition, just by exercising more. Fro the same amount of calories, the timing of what you eat is also very improtant. Eat most of your meals in the morning and almost nothing in the evening.

Question 5

i'm wondering if i exercise 2 hours per day, how many calories should i eat to lose 3 pounds a week?

Accepted Answer

Bad plan: 2 hours of exercise per day is excessive and cutting calories on top of it will only lead to short term weight loss before your metabolism slows down for self preservation.  At 41, you are also risking overuse injuries with that much exercise.  You should aim for 1/2-1 pound per week and exercise smarter and more efficiently at higher intensity for shorter duration.

Question 6

i've been on a calorie deficit. the first week i lost 3 pounds but then i gained back a pound and have not lost any weight in two weeks?

Accepted Answer

Dietician: You are advised to have at least one consultation with a registered dietitian who will advise you on your ideal weight, critique your eating habits, take into consideration your daily physical activities and outline a proper diet in order to attain your eventual weight goal. Weight loss should be slow but steady with no crash dieting. I'd supplement your diet with a multivitamin containing iron.

Question 7

is a weight loss goal of only 1/3 of a pound per week too insignificant? deficit of only 200 calories a day?

Accepted Answer

Weight loss: 1/3 of a pound a week is OK.
The more rapidly you lose weight the more new clothing you will need.
Take your time and enjoy the next 60 or more years ahead of you.

Question 8

to lose 1pound per week one should have a 3500 calorie deficit. if i take 1200 calories a day then to lose weight i should  burn 1700 calories a day?

Accepted Answer

Math looks correct: In theory, the math works.  In reality, how would one know she is burning 1700 calories a day?  It's hard enough trying to figure out how many calories one is eating, but it's a lot harder to figure out how many calories are being used!

Question 9

if drinking protein shakes, must you work out even longer to create a calorie deficit to lose body fat?

Accepted Answer

Yes and no....: If you are adhering to a low carb or low gycemic diet, no.  If your diet is "regular" with much starch, the answer is yes.  If this is the case, you must displace some starch calcories, equivalent to your protein supplements.

Question 10

am i shrinking! i'm 16 and a guy i went on a diet of 1702 calories to lose 10 pounds, i lost 5 now i'm 136lbs i went from 5'4 3/4 to now 5'4 in weeks?

Accepted Answer

Unlikely: Did you use a different scale?  And if you used the same scale you may have had some sort of error.  Weight loss may effect you ability to grow but I do not think it would shrink your height
