There are a variety of definitions of what moderate-intensity exercise is, but it typically falls between about 70 to 80 percent of your maximum heart rate, which would be a level 4 to 6 on a 10-point perceived exertion scale. That means you are breathing harder than normal but can carry on a conversation without much difficulty and you feel pretty comfortable with what you're doing. The American College of Sports Medicine (ACSM) often recommends this level of intensity in its exercise guidelines. The lower end of this range usually incorporates the fat burning zone.
Maybe you are trying too many things. If you keep switching diets and are doing too much exercise, your body is trying to balance itself. it might also be caused by lack of sleep or too much stress. Do moderate exercise and start eating a little bit cleaner and the pounds will come off. If you still don't notice a difference, talk to your doctor. You might have a thyroid problem or some other medical issue.
It depends on just how many potatoes we're talking here! One medium potato has around 37 grams of carbs, so if you limit your carb count elsewhere, this is no problem. What you really have to watch out for are the toppings, like butter, cheese, sour cream, bacon, and rich sauces like gravy. Do some math to figure out how to balance the carbs from your potato and toppings with the other foods you eat.
Lose fat with high-intensity interval training (HIIT). If you're trying to lose weight fast, HIIT training can super-charge your metabolism for upwards of 24 hours after exercising. This means your body will continue burning calories long after you've ended your workout. HIIT burns more calories in less time than steady-state cardio. In one study, researchers looked at two groups, one running for 30 to 60 minutes three times per week, the other doing four to six 30-second treadmill sprints, resting for four to six minutes between each sprint. After six weeks, it was found that the group doing HIIT training lost more weight.
If you've been lifting moderately heavy weights but are still looking to drop belly fat, it's time to pick up the intensity by using heavier weights and cutting down on rest time between reps, says Tyler Spraul, CSCS, a certified strength and conditioning specialist and the head trainer at Exercise.com. "Lifting heavy is where you see more an afterburn effect. Your body continues to burn calories even after you leave the gym," Spraul says. Just be sure that your technique doesn't suffer as you increase your weight, which can lead to injury. If you're new to strength training, this 15-minute total-body workout is a great place to start.
