Question 1

is the 'venus factor' diet genuine? as in it says the hormone leptin is why women retain weight/fat.  due to having me, i can no longer excercise

Accepted Answer

Leptin is a hormone: That mediates long-term regulation of energy balance, suppresses food intake and thereby induces weight loss. Resistance to leptin can cause obesity. Venus factor is a rigorous program. Seek individualized plan relevant to your situation with physical therapist and/or nutritionist, and improve sleep hygiene as good sleep increases leptin. Consider leptin resistance diet and lifestyle changes.

Question 2

how to reduce leptin resistance. i am working out 10 hours a week for 10 years. and i am on a low carb diet. taking omega3. what else can i do?

Accepted Answer

Leptin effectss: There is no available treatment for leptin resistance.  You need to total up the calories that you are eating.  There are a number of websites that will give you this information.  Low carbohydrates may be counterbalanced by high caloric intake of fats.  If you are not losing weight, you are not burning more calories than you are taking in.  You have to count them!

Question 3

what is leptin?

Accepted Answer

A hormone: Hi. Leptin is a hormone made by adipose tissue (fat cells) that has the effect on the satiety center in the hypothalamus in the brain to tell you you're full, it's OK to stop eating. Obese people are leptin resistant, not leptin deficient. A leptin receptor agonist, metreleptin, was recently approved for treatment of people with little/no adipose tissue (generalized lipodystrophy).

Question 4

what happens when leptin levels rise?

Accepted Answer

Hunger decreases: Leptin is a neuro-transmitter produced by fat cells that tell the brains that you need calories (starvation indicator), When it falls you get the sensation of hunger. When it rises you become satiated.

Question 5

how can i find out if i have a normal leptin level?

Accepted Answer

Men1-5ng/wmen7-13ng: ]in healthy individuals, baseline leptin levels are between 1-5 ng/dl in men and 7-13 ng/dl in women. Human leptin is a protein of 167 amino acids. It is manufactured primarily in the adipocytes of white adipose tissue, and the level of circulating leptin is directly proportional to the total amount of fat in the body.

Question 6

what effect does dieting have on leptin levels?

Accepted Answer

Lowers level: If dieting is intended to lower fat content, then there should be expected drop in leptin levels as this hormone (cytokine) is produced by the fat cells (adipocytes).

Question 7

what is the role of leptin in weight management?

Accepted Answer

Satiation: Leptin is a hormone which is released from fat cells and regulates the fat stores in the body. If the body has sufficient amounts of fat, satiety signals will be sent to the hypothalamus, the region of the brain which is responsible for regulating appetite and metabolic rate. If the body lacks adequate amounts of fat, another hormone, known as ghrelin, will stimulate sensations of hunger.

Question 8

are obese people resistant to leptin?

Accepted Answer

Yes: Although leptin is a circulating signal that reduces appetite, obese individuals generally exhibit an unusually high circulating concentration of leptin. These people are said to be resistant to the effects of leptin, in much the same way that people with type 2 diabetes are resistant to the effects of insulin.

Question 9

is there an after effect of a 'leptin deficiency'?

Accepted Answer

Thyroid issues: Thyroid function is closely related to leptin's secretion by the adipose tissue. In states of leptin-deficiency, the circadian rhythm of TSH is altered, leading to central hypothyroidism in animal models. In humans, central hypothyroidism has also been described in rare cases of congenital leptin deficiency.

Question 10

which fruits have leptin?

Accepted Answer

Fish-rich diet: Digestive tract cannot absorb leptin, so even if you could find a food rich in leptin it wouldn't help - forget about finding foods rich in leptin. The body has to create it's own leptin. And as you lose weight, leptin levels drop, because fat itself causes the body to produce more leptin.
Latest study suggests that a fish-rich diet somehow makes your body more sensitive to leptin, &help wt loss.
