Healthier, Fitter & Leaner After 12-Day McDonalds Challenge Thanks to HIIT? Plus: TRX®, Fitness ↗ Fatness ↘ in Women

Written by | published on

Short news: Sprinting & TRX  "Have you already burned off that burger you had for lunch today?" If that's a question you're asking yourself regularly, you are at a high risk of misinterpreting a recent study by Christian Duval et al. (2017) as a license to eat how much you want, whatever you want, whenever you want. Unfortunately, a 12-week study in which young, healthy subjects were allowed to consume only three more or less energy-adequate meals is not representative of the futile "if you eat more/worse, just exercise more"-approach to diet and exercise. Apropos exercise, if you're still looking for the right exercise to get or stay fit and healthy, TRX training, the suspension training bodyweight exercise that has purportedly been developed by/for US Navy Seals seems to actually live up to some of its promises of developing strength, balance, flexibility and core stability - overall fitness (VO2max) improvements are yet probably its greatest...

Sucralose: Sweet Taste / Energy Content Mismatch Offsets Our Nutrient Gauge and May Make us Overeat, but...

Beware: Splenda(R) is not sucralose, but 95% dextrose (D-glucose) and + maltodextrin combined with an undisclosed small amount of mostly indigestible sucralose. "These findings further reinforce the idea that 'sugar-free' varieties of processed food and drink may not be as inert as we anticipated. Artificial sweeteners can actually change how animals perceive the sweetness of their food, with a discrepancy between sweetness and energy levels prompting an increase in caloric consumption," Professor Herzog said according to the press release the University of Sydney published last week alongside the publication of a study that was co-authored by Herzog in CELL Metabolism - a study with the telling title "Sucralose Promotes Food Intake through NPY and a Neuronal Fasting Response" (Wang. 2016).

High Dose Caffeine Restores Insulin Sensitivity and Limits Total as Well as Visceral Fat Gain Due to High Sugar Diets

Written by | published on

Yes, the study at hand is on caffeine, but the results are relevant for coffee, too. A decade ago, the medical community though coffee would dehydrate you, would make you insulin resistant and would increase your risk of heart disease. Recent studies show that coffee does not negatively affect your hydration status (Killer. 2014), that higher coffee consumption is associated with reduced diabetes risk and increasing your coffee consumption can reduce your risk of T2DM (Akash. 2014) and that a "daily intake of ∼2 to 3 cups of coffee appears to be safe and is associated with neutral to beneficial effects" on coronary heart disease, congestive heart failure, arrhythmias, and stroke (O'Keefe. 2013). Against that background it may not be as surprising as it would have been 10 years ago that Joana C. Coelho, et al. (2016) found caffeine to be able to restores insulin sensitivity and glucose tolerance in high-sucrose diet rats. And yet, I personally believe that it is stil...

Path to Fat-Induced Obesity is Sprinkled With Salt - Sodium Boosts Food & Energy Intake & Reduces Fat's Satiety Effect

Written by | published on

Think you cannot eat the whole pizza? Add salt - this should "help" with the hardest all-you-can-eat challenges. I am not telling you something new if I tell you that excess fat consumption has been linked to the development of obesity. I hope that it's also not news to you that the consistent association between high(er) fat intakes and weight gain in epidemiological studies cannot be reproduced in human studies where the diet is just high in fat and doesn't have the perfect "potato chips"-combination of fat and carbohydrate that has not just been proven to increase food intake, but also to have pro-addictive effects on the brain (Hoch. 2015). The fat to carbohydrate ratio Hoch et al. identified as a crucial determinant of snack food intake and brain reward responses in their 2015 study is yet not the only characteristic feature of potato chips.

Artificial Sweetener Saccharin Increases Weight Gain in Rodent Study Without Increasing Food Intake | Plus: Meta-Analysis of Human Studies Says: "No Reason to Worry!"

Written by | published on
Image
Should you freak out about a small increase in body weight in a small-scale rodent study that is attributed to the consumption of saccharin in yogurt? While epidemiological studies show that the consumption of products containing non-nutritive sweeteners (NNS) is associated with increased adiposity (Colditz. 1990; Fowler. 2008), type 2 diabetes mellitus (T2DM), metabolic syndrome and cardiovascular disease (Dhingra. 2007; Lutsey, Steffen. 2008). A mechanistic link between aspartame, sucralose, stevia & co and weight gain as well as its ill metabolic and cardiovascular consequences in humans is non-existent  ( learn more ). Rather than weight increases controlled human studies show that the consumption of artificially sweetened foods promote, not hinder the loss of body fat  (Sørensen. 2014).
