I’m writing this because many people get caught up in the details but miss the big picture. If the big pieces are in place, the minor details really don’t matter much. This is about doing the 20% that get you 80% of the benefit. This is about the fundamental of fat loss. Fat loss itself should be considered an enabling factor, and not an end in itself. You main goal should be health and fitness. This requires mobility, which requires a relatively lean body. Of course looking good nekid doesn’t hurt either.
Calorie restriction You can’t lose weight unless you are in a calorie deficit overall. In order to lose a pound of fat per week, you need to create a deficit of 3500 calories/week. Note that the main source of this deficit must come from diet. You can’t out-train a bad diet. As a “rule of thumb”, 10-12 cal/lb tends to be a decent starting point for fat loss diets, and then you can adjust for effect.
Nutrient cycling While you have to, on average, be in a calorie deficit, you can’t stay there. If you stay in a deficit long enough, your metabolism will slow. You need to refeed periodically to the point that you are satisfied. This is best done every 1-3 days. Eating until you’re satisfied more than once a day will likely not provide adequate calorie restriction. Going more than 3 days could cause metabolic slowdown, or “starvation mode”.
Get adequate proteinAdequate protein is required to ensure that fat is lost, and not muscle. Retaining muscle is crucial for health and fitness. Remember that health and fitness is the goal. Muscle also helps you keep the fat off by increasing you metabolism slightly. Depending on activity levels, you may need more or less protein, however, the common recommendation of 1g/lb of lean body mass is close enough for most purposes.
Eat the right fatsThere are several benefits to getting adequate fat. First, it’s satisfying. Adding fat to your diet makes it less likely that you will be hungry and reach for inappropriate foods. Second, fat adds flavour, reducing the blandness of the food, improving the adherence to the diet. Including about 10-14 grams of fat per meal slows gastric emptying and therefore keeps you satisfied longer. The type of fats matter. Omega 6 is an essential fat but it’s easy to get far too much in normal diets. You only need a few grams/day. Too much causes inflammation. It’s better to limit your O6 by limiting vegetable oils and focus more on O3. Getting a few grams of O3 reduces inflammation and supports fat loss. A few ounces of salmon will supply all you need. Alternatively, fish oil capsules will work but you need to make sure they’re not rancid. Saturated and monounsaturated fats are perfectly OK to eat but avoid all artificial trans fats. This is found in any hydrogenated fats. Stay away from any solid fat derived from non-tropical plant sources. (for example, butter and coconut oil are OK but margarine is not). Be careful with fats due to their high calorie content.
CarbsAs long as you meet the calorie deficit and maintain adequate fat and protein, it doesn’t leave a lot of room for carbs. For some people restricting carbs even further may provide some advantage but not in all cases. Carbs in the 60-200 g/day range are probably OK with about 100 – 150 grams as optimal for most people. Should you decide to under 60g/day make sure you keep your protein high and keep an eye on your thyroid function.
Those are the basics. Everything else is details. Some details I think are important are as follows.
Quality mattersPay attention to the quality of your food. Variety makes a big difference. Too much of any one thing can cause imbalances and nutrient deficiencies. This link gives you the basics of a good diet:
