Rather than a long and low-intensity cardio workout, try the HIIT method of cardio: intense, fast-paced intervals that leave you completely exhausted after only a 20- to 30-minute session. This form of cardio training increases the afterburn effect, allowing your body to continue burning calories long after your workout is over. You can rotate between 30 seconds of your favorite exercises, with rest in between, as long as they work different muscle groups—such as squats, push-ups and kettlebell swings.
Sadly, with the warmer months already upon us, you don’t have that kind of time. In order to get your body where you want it to be (and fast) you’re going to need to dig in with a program that forces results by attrition. The goal is to train so hard, so often, and so well that your body has no choice but to respond with a markedly increased capacity to torch fat.
Dr. Smith says the regimented plan involves scheduling meals, mainly of plant-based foods in controlled portions, to create a negative energy balance... where your body extracts energy from stored fat, thereby boosting calorie burn and reducing fat. Most dieters don't realize that simply by cutting back as little as 20 percent at each meal, they can lose a significant amount of weight.
In order to produce the desired results, you’re going to have to submit to a slightly less academic—but utterly more chaotic—method of training. While most programs carefully manipulate a multitude of variables, we’re going to whittle that list down to those that are most conducive to fat loss and muscle preservation. It’s going to be tough, but it’s going to work.
After somewhere between three and five hours, your body stops processing its last meal. There's nothing left to absorb, so insulin levels naturally decrease. Then, somewhere between eight and 12 hours after that last meal, your body starts burning stored fat. (Why don't you start burning fat sooner? Biology is sometimes a pain in the ass; it's like our bodies will do anything to hang on to fat.)
But before we get into how to go about losing weight, please consider this: Weight loss isn’t a healthy goal for everyone, Susan Albers, Psy.D., a psychologist at the Cleveland Clinic specializing in body image and eating issues, tells SELF. “I work in a medical facility,” she says. “I have access to people’s blood work. You can be healthy or unhealthy at every size.”
