How much you consume vs. how much energy your burn is the most important concept for effective weight loss. There’s no getting around the 1st Law Of Thermodynamics; if you burn more energy than you take in, you will lose weight, if you burn less, energy will be stored. Beyond this, there are ways of making it even more efficient than purely calorie restriction. First I’ll cover the quantity of calories, then we’ll get into the quality and timing of calories.
As far as quantity goes, you burn about 10 times your body weight in calories just by being alive. If you actually get out of bed and move around, you’ll burn about your bodyweight times 13 or 14. To illustrate this; a 180 lb person, who is mostly sedentary (office job) would need to consume about 2340-2520 calories per day to stay the same weight (180*13 to 180*14). These numbers aren’t exact, but through experience I have found they work well. In order to lose weight, subtract 200-500 calories per day from your maintenance level. To gain weight (i.e. muscle) add 500 calories per day (and don’t forget to lift lots of heavy weights!)
Quality is the next consideration. If I were to just my maintenance level of calories per day of fast food, first, I’d be hungry still because fast food is very calorie dense. Secondly, I wouldn’t be very healthy and would be lacking in many nutrients due to the poor nutritional value of processed foods . Even if you are consuming the same total amount of calories, getting those calories from whole foods (fresh fruits, vegetables and lean meats) would be a lot healthier and lead to more effective weight loss. This will help your body get the vitamins and nutrients it needs and go a long way towards feeling satisfied. You pretty much can’t eat too many fruits and veggies.
The last consideration is timing. The last thing you want to do is have a lot of calories right before going to bed. When do we traditionally have dessert…oh yeah, at night! Japanese sumo wrestlers, known for their girth, deliberately don’t eat much during the day and have a huge meal at night in order to gain weight. So, if you skip breakfast, have a light lunch, then have a large evening meal followed by dessert you are eating like a sumo wrestler! When you consume a lot of calories at the end of the day…you don’t have any day left to burn them. As soon as you go to sleep, your metabolism slows way down and all the excess is going to get stored as fat.
The best time to have excess sugars or carbs (if you must) would be early in the day, so you have the rest of the day to burn them off. It is good to start the day with a breakfast that has a mix of protein, healthy fats (nuts, eggs), and perhaps a complex carb like whole grain bread. Have a sensible, balanced, lunch and dinner, with a healthy snack or two mixed in. A post-workout recovery meal is good, heavy on protein with some carbs like a protein shake made with yogurt. No matter what, don’t eat a lot of calories at night, or anything after around 8 pm.
When you get the quantity, quality, and timing of your calories correct, add in some effective exercise such as kettlebells, and this will make for a very effective weight loss program.
