Fat cells make up adipose tissues. Most fat in our body is stored in adipose tissue. It is true that we do not lose fat cells. Fat cells would only shrink in size. We do respiration all the time, and we need glucose to do it. The sources of glucose include: direct intake, conversion from other sugars, conversion from lipids. If we intake small amount of ...

Currently I am not aware of any scientifically based recommendations for levels of healthy body fat. There are empirical observations and actuarial tables/considerations, but there hasn't been a definitive "For a 30 year old Caucasian male, 8-15% body fat is ideal for health" studies out yet. There was a study in 2000 that was published in the American ...

Burning 3,500 calories equals 1 pound of weight loss. To lose 1 kilogram of body weight, you would need to create a deficit of about 7,700 calories. As stated above, 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical ...

No, gynecomastia is a hormonal condition in which mammary tissue develops and enlarges in a male. Pseudogynecomastia is the word for what you're describing. How do you know what you have is only pseudogynecomastia? Have you consulted a doctor and know for sure? If not, you need to stop looking for solutions and look for the cause first. You can't solve it if ...

These dark circles can likely be attributed to vascular network prominence caused by hollowing of the contents of the orbital rim, pigmentary changes in the periorbital area caused by extravasated hemoglobin and its breakdown products (bilirubin and biliverdin), or to visibly accumulating fluid in the lower eyelid due to local processes such as atopy or ...

All models are wrong, but some are useful. The same is true for the body mass index. In general, people with a higher BMI have a higher chance of getting obesity-related illnesses than those with a BMI in the 18-25 range. But of course, there are exceptions like the one you mention. That's no reason to discard the entire BMI, because it does work in many ...

No, you are not overweight at all, and whoever told you it was a good idea to even consider a "diet" was very mistaken. Don't listen to them. At 120 pounds and 5'5", your Body Mass Index is 20.0, which is about the middle of the normal range -- an excellent place to be. BMI Categories: Underweight = <18.5 Normal weight = 18.5–24.9 ...

Besides changing the amount of calories you expend or consume there aren't many more options. You might attempt to reduce your stress level. The 1994 paper Stress-induced cortisol response and fat distribution in women and the 2000 paper Stress and Body Shape: Stress-Induced Cortisol Secretion Is Consistently Greater Among Women With Central Fat indicated a ...

I think there is only so little you can do about the fat accumulation. These things are work of natural evolution and genetics. From the Female body shape article in Wikipedia: Estrogens cause higher levels of fat to be stored in a female body than in a male body. They also affect body fat distribution, causing fat to be stored in the buttocks, thighs, ...

The short answer is no, your metabolism isn't really driven by your heart rate. The basic definition of metabolism is that it is the process by which your body converts the food and liquid that you consume into energy to fuel the body. This can be generally divided into two components, catabolism, which is the breaking down of ingested items into energy, ...

Insulin Resistance, Body Weight, Obesity, Body Composition, and the Menopausal Transition (ScienceDirect, 2000) Because bone and muscle have greater density than water, a person with a larger percentage of fat-free mass will weigh more in the water. Conversely, a larger amount of fat mass will make the body lighter in the water. The density of: ...

You asked for any evidence, and we have this paper, Increased salt consumption induces body water conservation and decreases fluid intake which is interpreted in this newspaper article. Essentially, a higher salt intake does not induce a corresponding increase in free water intake. But renal excretion of water still continues at a rate higher than that ...

The bile is produced in the liver and stored in the gallbladder. After a meal, fats trigger gallbladder contraction, which results in the release of the bile into the small intestine. The bile helps to digest fats. The liver is connected to the small intestine by the common bile duct. When your gallbladder is removed, the bile will flow from the liver via ...

Let's not conflate two different problems with BMI here. One the one hand you can have a low body fat percentage and still have a high BMI, but that only applies to body builders who exercise at a near professional level. Such a person will not get wrongly diagnosed by his or her doctor of being overweight. So, this shouldn't be a problem, however, as Carey ...

1. Does wearing a corset have any disadvantages? Yes. The wearing of a corset for extended periods of time to maintain or reduce waist size is called tightlacing. It is commented (though nowhere I can cite) that to effectively tightlace you need to use a Victorian-style steel/bone corset as modern elastic/rubber/plastic corsets don't exert enough force. A ...

Losing weight via means of altering your diet will be safest choice, however, that doesn't mean it is your only option. In my opinion, dieting is an incredibly vague term. Ensuring you are eating a balanced diet and eating within your daily needs is better way to put it. When you consume an excess of calories that your body doesn't need it often stores this ...

The book Living a Century or More by William Cortvriendt MD, which has a lot of scientific sources that I don't have the expertise to judge but seem reliable, says in the subchapter "Omega-3 PUFAs and inflammation" that ...COX can in fact stimulate or inhibit inflammation. When omega-3 PUFAs come into contact with COX, they will inhibit inflammation. ...

Does not really answer your question regarding where fat cells go when you lose weight as it has been already discussed previously by the previous posts, but I had to share the link to the video on "Where does fat go when you lose it?". The biochemistry behind it is: Fat + Oxygen -> Carbon Dioxide + Water C55H104O6 + 78O2 -> 55CO2 + 52H2O Please refer ...

From the NIH: Several sources of information suggest that human beings evolved on a diet with a ratio of omega-6 to omega-3 essential fatty acids (EFA) of approximately 1 whereas in Western diets the ratio is 15/1-16.7/1 This is not undisputed though. https://en.wikipedia.org/wiki/Omega-3_fatty_acid#Interconversion explains the importance. It's hard to ...

Answer: No Summary Metabolic effects of caffeine may vary depending on whether one is 'naive' to caffeine (infrequent user) or 'accustomed' to caffeine (daily user). Metabolic effects may also vary due to genetics, specifically a polymorphism on the CYP1A1/2 enzyme (1) One review notes that, after looking at the differences in metabolism between humans ...

So with everything related with diet there are two effects: whether a particularly diet affects what macronutrients you eat, and the effect of the food itself. According to NHS advice green tea in the amounts that you would consume by drinking it have limited effects on the metabolism. Missing from this advice is the evidence that in larger doses green tea ...

Going on such a diet (one that is void of fat) for sustained periods of time is simply not possible. Fat is an essential macronutrient your body needs. Never go on a diet that is void of fat. Fat is mandatory for the digestion and absorption of fat soluble micro nutrients (Vitamin A, D, E, and K). Fats are also sources of EFAs (Essential Fatty Acids). EFAs ...

A mathematical model has been created to examine the relationship between diet and exercise with respect to weight loss; Quantification of the effect of energy imbalance on bodyweight. The NIH has provided a web based tool based on this work to help you plan a diet to lose weight, the body weight planner. Note that 60-80% of calories consumed is used by ...

Background: Basal Metabolic Rate is the minimal rate of energy expenditure per unit time by endothermic animals at rest. Several BMR equations exist but the most notable one was the Harris-Benedict equation (revised 1984), which was created in 1919 and was the 'best' until 1990 until The Mifflin St Jeor Equation. These equations use the same factors: P ...

conscious tighten abdominal muscles would help me reduce abdominal fat. No it wont. Does tightening abdominal muscles all the time not harm my body? To build muscle you essentially need to damage it so that it comes back stronger when it recovers/rebuilds. This is the foundation of developing strength and building muscle (Cell water/glucose biology aside)....

Immediately after dinner - No. The body is re-directing a significant amount of blood to your stomach region to deal with the dinner you just had. Therefore, a run would not be advisable. You should ideally wait at least 2 hours after dinner and if the dinner was heavy, at least 4 hours to allow for the food to be digested. Short answer: Wait for 2 to 4 ...

More physical activity would very probably be a good idea. Body fat distribution has genetic determinants, and you cannot really target a body area for fat reduction. Conversely, exercising can have an impact on muscles and general fitness, in addition to improving your mood and maybe helping you be more satisfied with your body. It does not have to be ...

In short, 1,000 excessive calories from food does not translate into 1,000 calories of body fat. The conversion rate is highest for fats and lowest for proteins and may greatly depend on genetics. 1) What is the conversion rate for energy in macronutrients consumed to energy in fat stored? It depends greatly on a person and foods eaten, because some energy ...

This might sound unfortunately obvious, but exercising and reducing fatty food intake is all you can do to reduce body fat. There's no real trick other than to change your diet and put a time investment into exercise. Something I've noticed is that it is difficult to maintain a diet while working in an office. It's difficult to focus mentally when you're ...

As well as any other measurements it doesn't say much on it's own. You need to use it along with other personal details (and measurements) to get some meaning of it. One of the problems with BMI is that muscle weighs more than fat, so athletes (specially the ones that practise sports that rely on strength) tends to break the BMI meaning. It work well in ...
