Here's a fact most of the weight loss industry won't tell you: your body really doesn't want you to lose weight!
Researchers refer to this as "adaptive thermogenesis", your body preventing too many calories from being burned in the face of potential starvation (which is what it sees a diet as).
So, the way to KEEP losing weight is to continually "trick" the body into thinking it isn't dieting at all. In pre-historic times, we were forced to go long periods without food, and we had to preserve fat tissue to keep us alive ahead of our next meal (whenever that was going to be).
When we diet, our body sees this as a potential threat to its survival and retaliates by slowing down our metabolism. And one of the ways this happens is via the slowing down of your Thermic Effect of Food (TEF). TEF refers to the calories burnt by your body to digest the food you eat (protein is the highest at 30%).
Precisely, if you are reducing your calories by 500, eventually your TEF is reduced by 10%, meaning you'll burn 50 calories less. It seems insignificant but over a long dieting period it adds up.
Then there's your Resting Metabolic Rate (RMR) that also decreases when you lose fat. A male trying to lose fat who is under 15% body fat will experience a 15% reduction of BMR, whilst a woman under 25% body fat will experience a 17-20% decrease.
You've most likely experienced less energy for training and daily life when dieting. When you're not restricting calories, you'll notice you can have an abundance of energy to tap your foot, go to the bathroom, get up to lock the door, etc. All of these calorie-burning activities are referred to as Non-Exercise Activity Thermogenesis (NEAT), and all of these "NEAT" activities are reduced also during the dieting periods.
So, increase leptin when you're dieting and you're doing your fat loss goals a favour!
The aforementioned reasons are why you can cease to keep losing fat. And the rest of the article will outline how to combat it.
What most dieters get wrong is thinking that after they've lost fat, their Total Daily Energy Expenditure (TDEE) is the same. But as we've learnt, the body adapts after periods in a calorie deficit. So, what does that look like?
Your new calorie intake = reduce calories by 10% when weight loss halts below half a kilo per week.
So, eating less food is one of the first steps to ensuring you keep losing body fat.
Where so many people go wrong is starting their diets by doing EVERYTHING as hardcore as possible: endless cardio, 5-6 weight sessions, and a large calorie deficit.
And it works... until fat loss stalls in the ways we've outlined. And they don't account for the changes!
And so, here's the "secret" -- we must keep introducing new strategies to keep our bodies losing weight, and more so, prevent fat loss from stalling. We're talking about:
It's all about having fresh weapons up your sleeve to fight your fat; it's a good idea to keep cardio in your back pocket for the first 4-6 weeks so you have something to surprise your body with.
Once 6 weeks have passed, adopting Low-Intensity Steady State (LISS) Cardio is a good idea. LISS cardio is performed at a low intensity: rowing, walking, swimming, or using any cardio machines at the gym like the elliptical machine.
Here's what we're talking about specifically:
Weeks 1-4: Weight training 5 x per week with no cardio
Week 4-6 -- Cardio (LISS) 3 times per week. Weight training stays consistent at 5 sessions a week.
Weeks 6-8 -- Cardio (LISS) 5 times per week. Weight training stays consistent at 5 sessions a week.
Weeks 8-10 -- Cardio (LISS) 5 times per week but going 1.5 times your previous distance. Weight training stays consistent at 5 sessions a week.
Weeks 10-12 -- Cardio (LISS) 7 times per week but going 1.5 times your previous distance (at 1.5 times the distance performed during weeks 1-8). Weight training stays consistent at 5 sessions a week.
FOOD INTAKE: Recalibrate your daily calorie intake by cutting it by about 10% after fat loss slows below half a kilogram a week.
It sounds so counterproductive but eating more carbohydrates at certain strategic stages can help with fat loss. We spoke about the hormone leptin and how it drops during periods of dieting which ultimately means we burn fewer calories.
Well, it just so happens that the way we INCREASE leptin again is by eating carbohydrates!
And we do this as part of a "refeed day", the process of eating lots of carbohydrates to replenish leptin. By implementing a refeed day, research suggests leptin may only be boosted by 5-10 hours. But the additional benefits of a refeed are:
So when should we have a refeed day? Scientists have no definite guidelines at the time we wrote this article. However, here are some strong guidelines:
- Men at 10% body fat or more: 1 x refeed day every 2 weeks
- Women at 20% body fat or more: 1 x refeed day every 2 weeks.
And if you happen to be <10% body fat (irrespective of gender) then has one refeed day per week. Keep in mind that these guidelines are just that: guidelines. Just don't go overboard and enter a calorie surplus too often, as that's obviously the worst thing you can do for your diet!
Dietary fat will also need to be drastically slashed on refeed days because fat doesn't increase leptin levels. But now for the fun part: how many carbohydrates you can eat!
You can work this out by taking the following steps:
And remember that in order to keep dietary fat intake low, you'll need carbohydrate sources low in fat. We're talking about:
- Low-fat pasta
- Maple syrup
So with the refeed day factored in, we now have a solid strategy to fight fat loss plateaus! The 5 steps for ensuring fat loss keeps progressing can roughly be boiled down to:
By remembering these steps you'll be giving yourself your best chance at not falling victim to a fat loss plateau, and losing the weight you want, faster!
