1. Why do so many people have the perception that exercise, rather than healthy eating and diet, are the solution to weight gain and obesity? Does the evidence show diet or exercise to be the solution to weight gain and obesity?
2. What are Wesley’s challenges with his weight? What things has he struggled most with and what efforts has he tried? Why do you think he’s been unsuccessful so far?
3. What are the long-term costs of obesity? And why should everyone be concerned?
4. From 1977-2000 Americans have doubled their daily intake of sugar. How did the McGovern report and the food industry’s subsequent lobbying efforts result in this increase?
5. What is the “science” of sugar? What is our body’s response to consuming high amounts of sugar? How does it involve our liver, pancreas and brain?
6. How does the video explain food “addiction?” What have experiments with rats shown? What does this mean for those who say that losing weight is a matter of will power?
Explanation / Answer
Answering any of the 3 questions based on CHEGG policies:
1. Weight gain and obseity is highly dependent on the body type. A body type with low BMR ( basal metabolic rate) would definitely take more time time to breakdown the food which he/she is consuming within the body system, whereas a person with a high BMR has less propensity to gain weight (compaing both low BMR and high BMR person upon consuming same amount of food). eating healthy and right are the basis for not allowing the body to gain weight with a moderate amount of exercise. People might be unaware of their body types. Ultimately one needs to be careful about the calories burnt vs calories gained from food. One should be really conscious of what one is consuming if one needs to manage weight.
3. Long term obesity can lead to effects like cardiovascular diseases, diabetes mellitus type 2, certain forms of cancer, asthma, osteoarthristis and reduced life expectancy.
Everyone should be concerned to maintain a good waist to hip size ratio to prevent these forms of diseases. Obesity is a drain to the individual, family ,society and the nation as the life expectancy may go down , work productivity may also go down to some extent (the time spent on disease might be more).
5.Sugar in the form of glucose raises insulin levels in the blood, that selectively deposits energy from foods into fat cells.Leptin is secreted by fat cells. More fat deposition means more leptin signaling from the brain, indicating the time to stop but if leptin receptors in the brain do not work properly( leptin resistance) it might lead to more hunger, more intake of food /carbs and higher deposition in the fat cells.
High level of sugar immediately signals the release of insulin from pancreas that channel it into fat cells, muscle cells etc bringing down the high glucose levels in the blood. High sugar consumption means more chanelling of them into fat cells, indicating greater release of leptin from the brain.
Excess of glucose is again converted to fatty acids (fatty acid synthesis) becoming triglycerides and so on. Liver also comes into picture over here as excessive fat my lead to fatty acid liver as liver is involved in transportation of these triglycerides.
