How to Lose Weight Fast: 3 Simple Steps, Based on Science

 

3 Simple Steps 

1. Lift weights three times per week

You don’t need to exercise to lose weight on this plan, but it will have extra benefits.

By lifting weights, you will burn lots of calories and prevent your metabolism from slowing down, which is a common side effect of losing weight (11, 12Trusted Source).

Studies on low carb diets show that you can gain a bit of muscle while losing significant amounts of body fat (13).

Try going to the gym three to four times a week to lift weights. If you’re new to the gym, ask a trainer for some advice.

If lifting weights is not an option for you, doing some cardio workouts like walking, jogging, running, cycling, or swimming will suffice. Both cardio and weightlifting can help with weight loss.

  2.Cut back on carbs

The most important part is to cut back on sugars and starches, or carbohydrates.

When you do that, your hunger levels go down, and you generally end up eating significantly fewer calories (1).

Instead of burning carbs for energy, your body now starts burning stored fat for energy.

Another benefit of cutting carbs is that it lowers insulin levels, causing the kidneys to shed excess sodium and water. This reduces bloating and unnecessary water weight (2, 3Trusted Source).

According to some dietitians, it’s not uncommon to lose up to 10 pounds (4.5 kg) — sometimes more — in the first week of eating this way. This weight loss includes both body fat and water weight.

One study in healthy women with obesity reported that a very low carb diet was more effective than a low fat diet for short-term weight loss (4Trusted Source).

Research suggests that a low carb diet can reduce appetite, which may lead you to eat fewer calories without thinking about it or feeling hungry (5).

Put simply, reducing carbs can lead to quick, easy weight loss.

3. Eat protein, fat, and vegetables

Each one of your meals should include a protein source, fat source, and low carb vegetables.

As a general rule, try eating two to three meals per day. If you find yourself hungry in the afternoon, add a fourth meal.

Constructing your meals in this way should bring your carb intake down to around 20–50 grams per day.

Protein

Eating plenty of protein is an essential part of this plan.

Evidence suggests that eating lots of protein may boost calorie expenditure by 80–100 calories per day (6Trusted Source, 7Trusted Source, 8Trusted Source).

High protein diets can also reduce cravings and obsessive thoughts about food by 60%, reduce the desire to snack late at night by half, and make you feel full. In one study, people on a higher protein diet ate 441 fewer calories per day (9Trusted Source, 10Trusted Source).

When it comes to losing weight, protein is a crucial nutrient to think about.

Healthy protein sources include:

Meat: beef, chicken, pork, and lamb

Fish and seafood: salmon, trout, and shrimp

Eggs: whole eggs with the yolk

Plant-based proteins: beans, legumes, and soy

Low carb vegetables

Don’t be afraid to load your plate with low carb vegetables. They are packed with nutrients and you can eat very large amounts without going over 20–50 net carbs per day.

A diet based mostly on lean protein sources and vegetables contains all the fiber, vitamins, and minerals you need to be healthy.

Many vegetables are low in carbs, including:

broccoli

cauliflower

spinach

tomatoes

kale

Brussels sprouts

cabbage

Swiss chard

lettuce

cucumber

Healthy fats

Don’t be afraid of eating fats. Trying to do low carb and low fat at the same time can make sticking to the diet very difficult.

Sources of healthy fats include:

olive oil

coconut oil

avocado oil

butter
