Hunger is based on fat stores (lipostatic hypothesis), glucose levels (glucostatic hypothesis) and cellular energy. The dual centre model of feeding describes the two areas of the hypothalamus involved in eating behaviour. When we are hungry we start eating, the body’s blood glucose levels increase and so do ghrelin levels. When we are full the Ventro Medial Nucleus (VMN) of the hypothalamus is activated which inhibits eating and satiety is reached. Blood glucose levels drop again after eating and the Lateral hypothalamus is activated (which initiates feeding) and we become hungry and the process starts again.
Atkins’s diet is based on low carbohydrates and high protein while the Ornish diet is based on a vegetarian diet with low or no protein intake but filled with amounts of fiber. The idea behind the Atkins’ diet is that there is too much refined sugar in our diet. Too many snack foods and breads contain refined sugar, white flour and high-fructose corn sugar that leads to a spike in our insulin which creates blood sugar to spike. So Atkins tells us to take these items out of our diet and replace them with any type of protein. This will create the metabolism to enter a state of ketosis or “Burn” of the internal fat we store in the body.
Such foods have very poor nutritional value, but are the most affordable. Another effect of this poor economy is that people are looking for the best value for their buck, leading to bigger portions. Even the fast food chains have caught on. With their “dollar menus,” it is sometimes cheaper to buy a dollar sandwich for everyone, than it is to go to the store and purchase fresh food to cook a healthy meal. I have noticed that the opposite is also true.
Some are uncontrollable, like genetics, and some are, such as choosing to eat the cupcake instead of the fiber bar. That is the funny thing: the high obesity rate can be lowered and maintained just by making healthier choices every day. Many of our lifestyle choices lead to us being overweight and obese, but that can easily change; as America continue to ignore the obesity rate, many of us are dying each day from this disease called diabetes. Because our lifestyle choices affect our weight, our health, and the chances of us becoming obese, we can reduce that by balancing our energy, having a more active lifestyle, eating a healthy diet, changing our environment, and getting more sleep. One of the main reasons of obesity is the lack of energy balance, meaning that the amount of food you eat is the right amount to manage your weight.
It also works because it is an alkaline diet, which means it helps remove acid wastes, or toxins from the body, many of which are found in our body fat. Most raw foods are not calorie dense, which means you can eat until you are full and have taken in far less calories than if you had eaten a typical cooked food meal. Raw foods are also full of fibers that promote regularity for the intestines. The body also recognizes raw food as “real food” and can process and metabolize it so that it aids the body systems in functioning well. It is proven that 9% of body fat can be lost over three months of following the raw food diet.
Many families eat from take away and restaurants because it is an easier and a quicker process then cooking a meal at home. Obesity only occurs when taking in more calories
The money would go much further if the person would purchase processed foods such as hot dogs, lunch meat and Ramen noodles. This meal may not always be the healthiest choice, but it would feed the family. Many people do not chose to eat this way, or to have their family eating like this, but when push comes to shove, one must purchase what they can afford to feed the whole family. A website on the effects of low family income states,"A poor family is much more likely to buy a large amount of cheap, unhealthy food that will feed their family than a small amount of nutritious food that will leave them hungry." (Effects of Low Family Income) Foods such as fresh fruits and vegetables do run high in the store, and it is much cheaper to buy canned fruit and vegetables, but these processed canned foods add more sugar and salt to the diet than the fresh do.
Many people believe buying fast food when you are busy helps you out. I believe in the long run that eating fast food causes obesity and that scheduling and making time to make healthier foods is a better choice. If you are in a hurry and it isn’t possible to make something health you should stop at a place that sells healthier choices. McDonalds is the choice for many people on the go, but you can go to Panera Bread or Chipotle and get better tasting and healthier choices. Another reason for obesity is that Americans don’t receive the amount of physical activity or exercise their bodies need.
Obesity in America is a huge problem. More than one third (35.7%) of adults in America are obese. Obesity related conditions and diseases include heart disease, stroke, diabetes and various types of cancer. These diseases have caused many deaths in the recent -past and should be avoided at all costs. In 2008, obesity cost the government $147 billion in medical expenditures.
Your body uses the triglycerides in your blood as energy between meals, but if you eat more calories than you burn off throughout the day you will have higher levels of triglycerides in your blood. Your body will turn them into fat and store the fat in your tissues. When you look at a nutrition label you will see how much saturated fat and unsaturated fat that food has. These are types of triglycerides. Saturated fat is bad fat and is found in all your meats and dairy products.
