“If you want to burn fat, that’s like burning logs in a bonfire. If you want the bonfire to keep burning at high temperature, like your metabolism, then you want to keep feeding it logs every three hours — that’s the little and often approach with food. If you stop fuelling it, then the body goes into starvation mode and it will hold on to calories more,” says Wadsworth. “So short term yes you lose weight, but give it a few weeks and it all piles on again.”
Next is using a heart rate monitor. The algorithms used to calculate calorie burn from heart rate have become increasingly sophisticated. The more hard data you can add, such as age, height, weight, gender, activity level, functional threshold heart rate (FTHR) etc, the more accurate the value you get will be. However, most heart rate based calculations are only 10-20% accurate.
Dr. Campos, it is unfortunate that you retain the medical community’s negative stance on the ketogenic diet, probably picked up in medical school when you studied ketoacidosis, in the midst of an obesity and type II diabetes epidemic that is growing every year, especially among populations who will never see the Harvard Health Letter. The medical community has failed in reversing this trend, especially among children, and the public is picking up the tab, in the form of higher health insurance premiums to treat chronic metabolic diseases which doctors cannot cure. The ketogenic diet does not bid its adherents to eat unhealthy processed meats, and the green leafy vegetables that it emphasizes are important in a number of nutritional deficiencies. People lose weight on the ketogenic diet, they lose their craving for sugar, they feel more satiety, they may become less depressed, their insulin receptors sensitivity is improved, and these are all the good outcomes you fail to mention. There is a growing body of research which demonstrates the neuroprotective effects of the ketogenic diet to slow cancer progression, as well as diseases like Parkinson’s and Alzheimer’s, for which there are no effective medical treatments. Please respect your patients by providing them with evidence-based medical outcomes, not opinions.

There is no doubt that swimming is one of the best exercises you can do for yourself, and you can burn about 500 calories per hour when you swim but is swimming the best way to lose weight? Is swimming a good exercise choice if your primary goal is to get rid of extra pounds or body fat? Experience and some research may show that swimming is not the best way to lose weight.
An hour of Pilates a few times per week is unlikely to lead to rapid weight loss, but by evaluating your daily calorie intake, you can achieve weight loss with Pilates. Because counting calories can be a challenging process, the American Council on Exercise recommends reducing the size of your meals by 10 to 15 percent, filling your diet with healthy, low-calorie foods and cutting out your consumption of alcohol, which is loaded with empty calories.
Unfortunately, hard training and calorie restriction don’t go well together. Cycling, especially at higher intensities, requires fuel and, if enough fuel isn’t provided, the quality of and the progress yielded by training will be compromised. To lose weight, the best time to do it is during a period when your training load is relatively low and you aren’t focussing on high intensity sessions. The off-season is probably the best time to try and shed a few pounds.
Exercise science shows that high-intensity interval training (HIIT) is a fast way to boost your fitness, rev your metabolism, and stimulate human growth hormone, all of which help you ultimately burn more fat. There’s no better place to push those max intervals than on a bike because there’s zero impact, just effort. Just find a quiet stretch of road or path, especially if it’s on a bit of an incline and go. Push as hard as you can for 10 to 20 seconds, go easy for double that time (20 to 40 seconds), and repeat eight times. Rest for four or five minutes, then do it again.
