Here are some definitions:
Swollen or distended beyond normal size by fluid or gaseous material.
Bloating is any abnormal general swelling, or increase in diameter of the abdominal area. As a symptom, the patient feels a full and tight abdomen.
Well I'd like to suggest to you that all overweight/obesity is caused by distension/swelling because of fluid retention - rather than by eating too many calories.
Dieting, by which I mean eating less food/fewer calories than the body requires in the mistaken belief that this will reduce obesity, is EXTREMELY HARMFUL. - The skin gets very much thinner very much faster, and the blood vessel walls get very much thinner very much faster too. - This obviously causes the blood vessel walls to be overstretched and stressed and much weaker, which results in them becoming distended (fluid retention) with extra fluid, so causing WEIGHT GAIN, NOT WEIGHT LOSS.
To reduce excess weight you need to reduce the fluid retention that has caused the weight gain. - So you need to avoid dieting/'slimming' and instead concentrate on avoiding salt and salty food, because that extra fluid in the veins is extra sodium and water, and to lose some of it you need to reduce your sodium intake.
When people whose blood vessels are weaker than the norm eat salt, the result is weight gain and obesity (because of excess sodium and water held in the blood vessels and elsewhere). This condition is also known as sodium retention, water retention, fluid retention, salt sensitivity or oedema. If these people reduce their salt intake they lose some of the excess sodium and water, and so lose weight, and if they eat plenty of fresh fruit and vegetables they lose weight faster, because the potassium in the fruit and vegetables displaces some of the excess sodium from the body.
Lose weight, reduce your risk of most cancers, high blood pressure, type 2 diabetes, stroke, heart disease, heart attack, vascular dementia, osteopenia, osteoporosis, hypercholesterolaemia, depression, liver and kidney problems, and improve your health in many other ways without drugs or expense by eating less salt! - Try it! - You will feel so much better!
