What Losing Weight Does To Your Body And Brain

Special thanks to John Gunstad, professor with the Department of Psychological Sciences at Kent State University, for speaking with us about his cutting-edge research on how losing weight affects brain function.

During the first week, you may find it easy to lose weight by simply switching to a healthier diet. But as your metabolism adjusts, you won’t burn as many calories as you used to. So losing additional weight will become harder. Making matters worse, as the fat melts away, you’ll start to experience an increase in appetite. After a meal, fat cells release a hormone called leptin into the bloodstream. This surge in leptin levels signals to your brain you’re full and should stop eating. But with less overall fat, people who lose weight show a measurable dip in leptin. Brain scans of obese patients who had lost 10% of their body weight revealed that less leptin leads to increased activity in regions of the brain that control our desire to eat. The result isn’t just an increased appetite but an even stronger urge to eat fatty, high-calorie foods, because your brain is trying to restore the body’s leptin levels to normal. However, fighting that early impulse to gorge on pizza and donuts is worth it in the long run. Besides the decreased risk of heart disease, hypertension, high cholesterol and type 2 diabetes, scientists studying overweight people discovered that losing just one pound of body weight reduces four pounds of pressure on knee joints. Losing excess weight also reduces strain on the blood vessels, increases blood flow to the brain, and boosts overall brain function. Several studies have shown that people who underwent weight-loss surgery saw an improvement in memory, concentration, and problem-solving skills in as soon as three months. Plus, brain scans indicate that people who lost weight and kept it off for nine months reacted differently when shown images of high-calorie foods than before they lost the weight. The brain regions that process reward, motivation, and taste didn’t react as strongly, whereas the areas that promote overall self-control had a boost in activity. So fighting those cravings early on might make them easier to control later. Turns out — like anything else — losing weight can get easier with practice.

Well most of the weight you lose Is fat If I’m not mistaken Yes more weight adds pressure on your joints, but if it’s all muscle, they should absorb the pressure way better right?

Weight can be in muscle and fat What happens if I am a bodybuilder with big muscles? Will that still pressure my knee joints?

Start by running around the street or walking home to school everyday for 1k and then start running some time, switch to a healthier diet unlike mcdonald where the food is extremely unhealthy even the salads.

I don't know why they keep saying your metabolism goes down as you lose weight in 1991 I lost weight as an engineer I wanted to do a scientific study so I ate the same thing everyday my weight loss was consistent from 400 lbs down to 250 lb proving that weight loss is a function of muscle mass and has nothing to do with how much you weigh.

I just take appetite supressants because most of the time I get urged to binge eating is not because I am hungry. In fact only less than 10% of the time are times I eat because I am hungry. 1. I usually eat to relieve stress by feeling full (35% of the time) 2. Or I just eat because I am bored or have nothing better else to do( 35% of the time) and also 3. I eat to fall asleep because I have severe insomnia and only efficient way is that if I eat something prior to bedtime I fall asleep easily like magic.

Never made pass the 1st phase
i went full salad and water only for 4 months, ran every day, and i can tell you that my body felt cleansed but i ate 3 potato chips and i got diarrhea for almost a week and couldnt stomach meat so easily. i felt good but also weak, so i started eating more meats and eventually maintained a rapid weight loss aswell as muscle gain, im proud of myself for not going anerexic

Proven to Stop Hunger Cravings in Their Tracks & Help You Melt Away up to 1 Pound of FAT Every 72 HOURS The massive, red, venomous snake was looking right at me. I held my breath. I didn't move an inch. Why did I risk my life for this cup of tea? I thought my life was about to come to a very sudden and painful end. Naturopath and a best-selling Amazon author who has helped over 14,793 women and men reclaim their health, fitness, and happiness with the advice they needed to improve their physical well-being. As a professional weight-loss expert, I was ashamed and frustrated by the weight Id gained after a difficult and complicated pregnancy. No matter which of my time-tested techniques I tried, I just couldn't get rid of pounds and pounds of stubborn excess fat! It was like I was a stranger in my own body, trapped in a shell I didn't even recognize anymore. The worst part was that I couldn't seem to do anything to get my life back to normal. I was disappointed, ashamed, and more alone than I ever been. I felt absolutely helpless. That all changed when I took a plane to Africa and discovered the delicious tea that made me burn body fat quickly and easily, without feeling hungry. http://clickmetertracking.com/msuf

I can lose weight very easily, if I don't TRY to eat a lot every day I lose 50-200g per day. Also, does it work to swim/run 3-6 hours a day to lose weight?

Basicallly all the processed food is just like cocaine / heroine . It’s not about “self control” but treating these food types as ciggys , if you have them they give a good feeling but there is a cost
