In my informal testing, the heart rate sensor isn't quite as snappy as the Fenix 5 Plus or Apple Watch 4's sensors, but it's accurate enough that I'm confident in its readings. Like those devices, the Instinct can also display notifications from your phone. Though if you're used to being able to do stuff with your notifications like I am, suddenly not being able to do anything with them can take some getting used to.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.
A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key. 
Insulin (in-suh-lin): A hormone made by the cells in your pancreas. Insulin helps your body store the glucose (sugar) from your meals. If you have diabetes and your pancreas is unable to make enough of this hormone, you may be prescribed medicines to help your liver make more or make your muscles more sensitive to the available insulin. If these medicines are not enough, you may be prescribed insulin shots.
Although it may be tempting to look for a quick fix for your weight loss woes, it's important to avoid fad diets to lose weight fast. According to a recent study from the University of Exeter and Bristol, yo-yo dieting may actually sabotage your weight loss goals because the brain interprets these diets as short famines. Instead of losing weight fast, they cause your body to fire signals to your brain to store more fat for future shortages, unintentionally derailing your attempts to drop those last ten pounds.
