Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.
To get the body into this fat burning mode foods that are high in carbohydrates have to be avoided during the first two weeks of the diet (the induction phase), after which time they are gradually reintroduced. It’s all made a lot easier by using the food list to select the right foods which will induce ketosis, and therefore encourage weight loss.
The Atkins diet has gone through numerous revisions over the years, though there was never any acknowledgement of flaws in any of the diet plans. Until recently, there have not been any studies on the safety or efficacy of the Atkins diet. Short-term studies have shown improvements in blood cholesterol and blood sugar and an increased weight loss over the first three to six months in comparison to control diets. Unfortunately, the weight loss is not sustained at one year, and the improvements that were seen were due to weight loss and not the actual diet. The long-term safety of low-carbohydrate, high-protein diets is unknown at this time. In a 2007 rating of diet books done by Consumer Reports, the Atkins diet was ranked at the bottom.
Also, men tend to lose weight where they need it most (read: belly), so it's often more immediately noticeable when overweight men start trimming down than when women do, as ladies' fat stores are typically more spread out, which is partly why they tend to lose weight at a slower pace than guys. Even basic, regular exercise -- ideally 30 to 60 minutes a day -- tends to reduce abdominal obesity, even if guys don’t technically lose weight.
i am 39 years old and have a good 35 lbs to lose. like you i ate whatever i wanted as a teen and stayed very thin (and i did literally no exercise) but then i hit 21 or so and realized i needed to cut back on calories and jog as weight slowly came on. then at 28-30 i got back to my teenage weight of 114 by jogging and watching carbs, i got married at 34 and since then pounds have just crept on for both my hubby and myself… i have tried everything :/
