Research: Will weight loss combines with exercise improve function as we age.

Combination of exercise and weight loss improves functional status as we age.  

Most of the elderly fear losing independence as they age.  As we age, human naturally lose some functional status.  Functional status refers to the ability of the elderly to function on their own without assistance.  It is believed that obesity and a lack of exercise increases the risk of frailty in older adults and thus, increases the risk of lower function.  

 

Research: Pedometer use may help with weight loss.

Pedometer use promotes weight loss success.

Emerging evidence suggests that being overweight and obese will increase your risk of all-cause mortality.   I know this is all-cause, but the elevation of risk is likely due to heart disease and diabetes type 2.   Exercise should induce healthy changes that would result in a reduction in such risks.  Although pedometer intervention is effective in increasing physical activity among adults with Type 2 diabetes, the usages impact on weight loss remains unclear.  

 

Research: Low-carb diets may increase risk of heart disorder

Low carbohydrate diets are not without risk.  

Low carbohydrate diets are at near epidemic levels and you cannot walk in a gym and throw a rock without hitting a half-dozen people that are currently following one form of the diet or another.   Restricting carbohydrates has become a popular way to lose weight quickly in recent years.  There are many different low-carbohydrate diets to include the Adkins, ketogenic, paleo, Protein Power and South Beach diets.  The low-carbohydrate books would like you to think that carbohydrates are the enemy, but reducing your carbohydrate intake might not be the panacea for good health that they want you to believe it is.  

 



Research: Combined dietary and exercise results in superior weight loss

Dietary and exercise combined are superior for fat loss than diet alone.

If you are like most Americans and you look in the mirror, you most certainly notice that your fat storage is around your belly.   Sure we all want abdominals of steel, but in reality, it is extremely unlikely most fo use will get there.  You can do crunches until your eyes meet and you will still be a little soft in the middle.  It has long been recognized that a slim waistline is made in the kitchen and not the gym, but many people have assumed that this means that the gym or exercise is not needed.   

 

Research: Substantial fat loss may lower risk of heart disease in normal weight individuals

Substantial fat loss reduces inflammatory markers for cardiometabolic disease in normal-weight individuals

I know after reading the title, you are asking yourself the question “How can someone be of normal-weight and safely lose body fat?”  The question is can someone be of normal-weight and still have too much fat and the answer is absolutely “yes”.  If you have a low amount of muscle mass and are very inactive, you will accumulate fat in the midsection and around your organs.  This is called viceral fat or central obesity and the accumulation of fat, especially in visceral area, is consider to be a significant risk factor for several chronic diseases such as diabetes type 2 and heart disease.  

 

Research: Exercise will not worsen sleep

Evening exercise does not appear to disrupt sleep or alter energy intake.

Just about anyone who has trouble sleeping has filled out a sleep hygiene questionnaire and received education to avoid exercise within 4 hours of bedtime because it will disrupt sleep and make you hungrier.  In today’s culture, following this advice makes evening exercise nearly impossible.  If you are like me, you are lucky to be home by 5:30 p.m.  

 

Research: Resistant dextrin may assist with weight loss

Resistant dextrin may improve insulin resistance and assist with weight loss.

Recently, I have noticed a new ingredient in many of the cereals I eat.  The additive is a compound called resistant dextrin.  Dextrin is a soluble gummy substance or prebiotic that is obtained by hydrolysis of starch, used as a thickening agent and in adhesives and dietary supplements.  Resistant dextrins are a class of soluble fiber isolated from wheat or corn that is believed to reduce the glycemic response and promote satiety. Dextrins are also believed to also improve insulin resistance and assist in the management of type 2 diabetes.  It is hypothesized to absorb water and should expand the gut and reduce your appetite, but there is limited evidence that prebiotics improves insulin resistance or reduce weight.

 

Research: App based self-monitoring works in weight loss

Cell phone apps that self-monitor can assist with  weight loss

A discussed in multiple other research projects, self-monitoring of dietary intake is essential for successful weight loss.  Self-monitoring is one means of behavioral weight loss treatment, but most of the research has been done through paper journals and logs. Past research has shown that people often start with the goal of recording their food intake.  Despite early success, most fail to continue over time. Very little research has involved newer cell phone applications as a means to monitor.  The good news is that today, you have multiple options to follow your diet, weight, exercise, and just about anything that might affect weight loss.
