When you hit the gym, the body releases a fat-liberating messenger called epinephrine, which attaches itself to fat cells and allows fat to be burned as fuel. And, you guessed it, carbohydrates come into play here. Refined carbs consumed before training suppress the exercise- and supplement-induced rise in epinephrine compared to eating the same amount of slower-digesting carbs. Refined carbs also boost insulin levels, further hampering fat-burning during the workout. Bottom line, avoid refined carbs altogether before training.
• If you’re a Restrictor personality type: While no foods should be off limits, some foods should be limited. For example, for the restrictor type personality, foods that you have trouble controlling yourself around should be kept out of the house. The more the temptation is there, the more likely you are to break down and overeat. This becomes even more important when you’re dieting and hunger and cravings are at an all time high.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
When attempting to lose body fat, insulin control is crucial. The total amount of insulin released by the body isn't related to just how many carbohydrates you eat but how fast those carbs are digested. Refined carbs digest quickly, raising insulin levels substantially, which is why you should avoid them. But if you do happen to eat, say, a bowl of cold cereal (typically a fast-digesting carb), you can still take measures to ensure those carbs digest more slowly. This will cause less insulin to be released and therefore have less of an impact on your ability to burn fat.
Sure, high-intensity cardio can help you torch calories, but ideally, you’ll also need to pump some iron to build metabolism-boosting muscle. That’s because strength training is one of the few activities you can do to spike the amount of calories you burn, even after you’re done with your workout. Case in point: one 2012 review of research found that while completing a 20-minute resistance training circuit may help you burn 200 calories, your body’s resting metabolic rate stays elevated for the next hour, helping you burn an additional 50 calories. Plus, when you lose weight, you lose some muscle with it, so building and maintaining that lean mass will help you achieve a more toned look.
While it may not be earth-shattering, there’s evidence to back up the advice that registered dietitians have been giving for decades. For many years, R.D.s have been urging weight-loss clients to eat dinner earlier and stop snacking a few hours before bed. It seemed like a no-brainer—after all, when was the last time a late-night binge consisted of a salad and carrot sticks?—but researchers from Brigham Young University decided to put the theory to the test.
Set up a box behind you and then lower your body until your glutes touch it. Touching the box requires you to “sit back” as you squat, as if you were lowering yourself into a chair, and this action gets the glutes and hamstrings maximally involved in the lift. It also helps you to perfect your squat form. You can start with a higher box and gradually move to smaller boxes as you improve, ultimately training your body to squat below parallel with no box at all. Better still, the box squat places no strain on the knees, so even people with knee problems can attempt it safely.
