Weight management

A six-month gluten-free diet significantly eased disability and supported a healthier body composition in women with relapsing-remitting multiple sclerosis (RRMS), a new small study found. The findings support growing evidence linking the gut-brain axis and metabolic inflammation to MS, and suggest that a gluten-free diet may be a promising dietary…

Having a higher body mass index (BMI), a measure of body fat based on a person’s height and weight, at diagnosis is tied to faster disability progression in people with multiple sclerosis (MS), according to a recent study in Sweden. This effect was particularly pronounced when excess weight…

I’ve written in the past that I thought I could stand to lose a few pounds. Well, I finally put a little effort into it and have managed to do exactly that by making some changes to my diet. I’d hoped that losing weight would reveal the washboard stomach…

People genetically prone to a higher body mass index (BMI) are also more likely to develop multiple sclerosis (MS), a study finds. The findings confirm an association between being overweight or obese and a higher likelihood of developing MS, and suggest that lifestyle changes to maintain a healthy weight…

Smoking and obesity are both independently associated with faster disease progression in multiple sclerosis (MS), but when both risk factors are present together, a synergistic effect results in faster disease progression than can be explained by either alone. “Smoking and obesity significantly interacted to increase the risk of disability…

The use of obesity medications — approved drugs for treating diabetes and promoting weight loss — is associated with a reduced chance of developing multiple sclerosis (MS), according to real-world data from the U.S. Food and Drug Administration (FDA), a study found. In particular, medicines that activate a receptor…

A six-month telehealth program designed to help participants change their dietary and lifestyle habits resulted in an increased level of physical activity and clinically relevant weight loss for most obese people with multiple sclerosis (MS) who took part, a clinical trial found. In fact, about 2 in 3 of…

Obese people with multiple sclerosis (MS) had faster disability accumulation, greater cognitive declines, and worse quality of life in the 15 years after diagnosis relative to patients with normal weight, according to an analysis of Swedish data. While it’s been known that obesity was a risk factor for developing…

My weight went off the scale when my multiple sclerosis (MS) meant that I could no longer safely get on the scale. This was probably about four years ago. In them there halcyon days (for me, anyway), I still shared our second-floor bedroom (first-floor, for those of us here…

I’ve been working on my health this last year or so, trying everything from a vegetarian diet to visiting an acupuncturist to help with muscle tension and headaches. All of it has been just wonderful. But the elephant in the room — the thing I still needed to…

Despite the fact that being obese or overweight may worsen multiple sclerosis (MS) prognosis, people with the neurodegenerative disease are not more likely to adopt weight loss diets, a small study suggests. The study, “Obesity, dieting, and multiple sclerosis,” was published in the journal Multiple Sclerosis and Related…

A link between fat molecules called ceramides and worsening disease in overweight and obese people with multiple sclerosis appears to exist, a study reports, with its findings suggesting that ceramides prompt the growth of immune cells called monocytes, which in turn spurs disease progression. These results also strengthen the likelihood that lifestyle factors, like diet and weight, can act as disease modifiers, its researchers said. High body mass index has been linked to the risk of developing MS, but for reasons that aren't clear. One idea is that weight-induced differences in lipids (fat molecules) in the blood, because they are involved in several cellular signaling processes, may affect MS and its course in people with higher BMIs. To test this hypothesis, a team led by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center and at the Icahn School of Medicine at Mount Sinai analyzed 54 patients with relapsing-remitting MS (MS), ages 18 to 60, and with normal or high BMIs (27 people in each group). Participants were followed for two years. BMI is a measure of body fat based on height and weight. A normal BMI is defined as one between 18.5 and 24.9, while a person is considered overweight with a BMI of 25–29.9, and obese it is 30 or higher. Researchers took blood samples, and looked for differences between the groups in terms of both immune cells and blood lipid profiles. They then validated their findings in a separate group of 91 RRMS patients. Patients with high BMIs tended to have more monocytes than those with normal BMIs. Monocytes can travel through the blood to tissues where they develop into macrophages, immune cells with various functions that are best known for "eating" invading bacteria. Monocytes can also travel to the brain and damage nerve fibers. Overweight and obese patients also had significantly higher levels of ceramides compared with normal-weight patients, and the researchers wondered if a link might exist between the two. Through a set of experiments in cells, they discovered that ceramides cause epigenetic changes in monocytes; that is, they alter the way their genomes are "read," so they alter gene activity. Specifically, ceramide-treated cells showed a type of epigenetic change called methylation — which generally turns genes "off" — in genes that normally help prevent cells from dividing. Conceptually, these genetic changes serve to unleash monocytes, leading them to grow more (proliferate) than they otherwise might. The researchers also found more methylation on the genomes of monocytes from high-BMI patients than those from low-BMI patients, and they noted that the overweight or obese patients also tended to have greater disease activity, worse disability progression, and more brain lesions on MRI (magnetic resonance imaging) scans on follow-up. Finally, the researchers tested a mouse model of MS, giving one group of mice a standard diet and another a high-fat diet. Mice fed the high-fat diet were found to have greater disease severity, more brain lesions, and more monocytes, confirming the findings seen in MS patients. "This study gives us a much-needed view into the environmental influences that can affect and change the behavior of cells in an individual's body," Kamilah Castro, the study's first author, said in a press release. "Our findings suggest that increased levels of saturated fat as a result of dietary habits are one likely cause of the epigenetic changes that advance MS, which gives us a starting point for a potential intervention." According to the team, the findings support the concept of nutri-epigenomics: that is, the ability of food to alter the way the genetic information is interpreted by each cell, and suggest that "weight management and dietary intervention" might affect MS prognosis. One limitation was the study's small size, its researchers noted. "While we consider our results … very exciting and mechanistic, we acknowledge that the potential consideration of ceramide levels as biomarkers for disease progression in MS would require validation ... using larger cohorts with a longitudinal and/or cross-sectional design," they concluded. "It will also be important to evaluate the effectiveness of dietary intervention (with an emphasis on the reduction of specific classes of saturated fats), as potential modulator of plasma ceramide levels and possibly of disease course in MS patients."

For many years I have been fighting the battle of the bulge while trying to decipher and combat many food intolerances. Every year I seem to come up short in the battle with losing weight, but I continue to try to shed the pounds. There are many challenges…

Researchers at McGill University Health Centre (MUHC) in Canada developed a new tool to diagnose cachexia — also called wasting syndrome. It’s characterized by weight loss, muscle atrophy, fatigue, weakness, and a significant loss of appetite in someone who is not trying to lose weight, mainly in cancer patients. The tool may also…
