How Many Calories Should An Obese Person Eat
1600 calories a day: It is hard to give an answer without knowing more about the individual patient's weight, height, and activity levels. In our research trials, we advise men to eat a 1600 calorie diet and then adjust the diet based on weight loss and exercise. This should cause weight loss of about 2-3 lb per week. ...Read more

Severely obese, will I lose more weight if I only eat half my calorie allowance like 1000 and still work on my treadmill 20 mins a day?
Need both: If your appropriate calorie intake is 2000 calories/day, reducing this by 500 calories/day will result in weight loss of a pound/week (3500 calories=one pound) Cutting more calories will result in more weight loss. BUT, cutting too low, & 1000 calories per day is near the too low point, may lower your metabolic rate and curtail weight loss. Burning calories through exercise will also be necessary ...Read moreSee 1 more doctor answer

It depends: A calorie is a measure of heat produced when you burn something. The only food that is primarily burned for energy is carbohydrates. Proteins and fats are used for many other purposes. So calorie counting really only matters when you count carbs. The typical person only needs about 150 grams of carbohydrate per day. That translates to 600 calories. ...Read moreSee 1 more doctor answer
Is it true that for obese men, doctors will recommend a strict 800 calorie diet but wont with obese women? If so, why?
I don't think so: The key to weight loss for men or women is reducing calories long-term. Men usually burn more calories per day than women, assuming similar levels of activity and similar body mass. Every individual's daily calorie needs are different, but to lose weight, one must keep reducing calories until the weight starts coming off. If weight is stable, it means the body still has enough calories to keep it. ...Read moreSee 1 more doctor answer
Has a genetic cause for obesity been found, that would make one obese even if eating a typical number of daily calories?
Genes and obesity: There are 70 different genes that predispose for obesity. Some influence where fat is stored, some influence hunger, some cause binge eating, and many influence metabolism. For our bariatric patients we are finding that they burn about 8 cal per pound. That's 1600 cal per day if they weigh 200lb. For genetically thin patients, they burn 13-14 cal per pound. That person could eat 2600 cal per day. ...Read more
