How to ACTUALLY Lose Belly Fat (Based on Science)



How to lose belly fat? Belly fat is really easy to gain yet often the hardest area to lose. There are 2 types: the annoying belly fat we all know that covers your abs, and a more dangerous type of belly fat stored deep within your organs known as visceral fat. To find out how to get rid of both types of stubborn belly fat (most effectively), I reached out to 5 of the world’s most qualified fat loss scientists and came up with 5 easy steps anyone can easily start doing today to lose belly fat. Includes belly fat workout and nutrition tips.

For the first and most important step, I spoke to Layne Norton. Scientific researcher, champion powerlifter, and honestly just a really smart dude who calls out BS when he sees it. Here’s what he said about belly fat. There is research showing that exercise can reduce visceral fat without actually causing weight loss. So it is a good idea to exercise in general, but specific exercises are not going to target preferentially belly fat. The real key to losing belly fat is just getting into a caloric deficit consistently and doing it for long enough.

How do you create a calorie deficit? Diet. And that’s where our next expert Alan Aragon comes in. Alan suggests to come up with a list of your 20 favorite foods by picking 3 across 6 food groups —high protein, fat, fibrous vegetables, starch, milk, and fruits — and making up the difference with 2 YOLO foods. Alan emphasized the importance of eating enough protein when dieting. Ending off, Alan shared an interesting finding: that when calories are matched, hypercaloric diets high in saturated fats may cause greater gains in visceral and ectopic fat than those high in polyunsaturated fats.

Now, let’s talk about the right type of “belly fat workout” to do to help you avoid regaining belly fat as soon as your diet is over. To explain this is Eric Trexler, pro natural bodybuilder and published scientist with a PhD in Human Movement Science. Eric maintains that there are some major benefits of resistance training (reduce muscle mass loss, which helps with better muscle definition and appetite regulation) if you’re trying to lose belly fat and really just trying to lose fat in general. Also, Eric reminds us that cardio can be a really helpful thing in keeping your expenditure higher when that non-exercise activity starts to go down over time. Everything that gets you moving — i.e., including NEAT — counts.

Even with nutrition and nailed down, there’s an overlooked variable when it comes to how to lose belly fat. What is it? Sleep, as explained by Exercise Science professor Bill Campbell. Bill shared about a recent study that suggests that there may be a link to sleep restriction leading to overeating, which causes a gain in body fat that is preferentially stored in the belly region. So I would suggest that you get about seven hours per night. Note that sleep matters regardless of whether you’re in a calorie deficit or not. More specifically, one study suggests that lack of sleep alone may in fact lead to more muscle loss and less fat loss during a diet.

So you now know how to get rid of your stubborn belly fat. But there’s one more thing you need. Laurin Conlin, a master coach, exercise scientist, and IFBB Bikini Pro will help explain what it is. First, it’s important to recognize that unless genetically you have little body fat on your abs and core area, you will probably need to get leaner than you’d think to lose belly fat. Second, take multiple measures of progress. You can use scale, weight, and measurements as quantitative feedback, but we also wanna look at qualitative feedback such as how your clothes are fitting, how you’re looking, and how much better you’re feeling. And lastly, be patient and recognize that you’re usually quitting right before it gets good. It doesn’t matter how perfect your program is, unless you remain consistent, you are short-changing yourself and your results.

  2. 這份 Q&A 為你將 5 位頂尖科學家的觀點濃縮成了最核心的實戰指南,幫助你快速掌握「減掉腹部脂肪」的底層邏輯與具體做法:

    🧬 基本觀念篇

    Q1:腹部脂肪有哪幾種?哪一種比較危險?

    A: 有兩種。一種是蓋在腹肌上的「皮下脂肪」,另一種是包裹在內臟深處的「內臟脂肪」。內臟脂肪更危險,容易引發各種健康問題。

    Q2:狂做仰臥起坐或捲腹,能優先瘦肚子嗎?

    A:絕對不能。 科學上沒有「局部減脂」這回事。減掉肚子的唯一核心法則是:持續保持熱量赤字(吃進去的熱量 < 消耗的熱量),並堅持足夠長的時間。

    🥗 飲食與營養篇 (Alan Aragon)

    Q3:減脂飲食一定要吃水煮餐、吃得很痛苦嗎?

    A:不用!你可以吃喜歡的食物。

    專家建議挑選 20 種你最喜歡的食物。其中 18 種從六大健康類別(肉/蛋白質、脂肪、蔬菜、澱粉、奶類、水果)中挑選,剩下 2 種留給你的「放縱食物」(比如甜點、酒)。這能幫你兼顧健康與心情,長期堅持下去。

    Q4:蛋白質在減脂期有多重要?

    A:極度重要。

    蛋白質能幫你保住肌肉。

    蛋白質的「食物熱效應」最高(吃純蛋白質,身體要額外消耗 30% 的熱量來消化它)。

    👉 建議攝取量:每天每公斤體重至少吃 1.6 克蛋白質。

    Q5:吃什麼會特別容易長「內臟脂肪」?

    A: 如果你在變胖(熱量超標),吃「飽和脂肪」比吃「多元不飽和脂肪」更容易囤積內臟脂肪。但如果你正在減脂(熱量赤字),全身脂肪都會減少,就不必特別擔心內臟脂肪的問題。

    🏋 運動與消耗篇 (Eric Trexler)

    Q6:想減肚子,我應該瘋狂做有氧,還是做重量訓練?

    A:強烈建議要做「重量訓練(阻力訓練)」。

    重訓能幫你保住肌肉,避免減脂後看起來乾癟。而且流失肌肉會導致你日後更容易餓、更容易把脂肪胖回來。

    Q7:那「有氧運動」在減脂期扮演什麼角色?

    A:用來「補足下降的日常消耗」。

    人在減脂期,身體會不自覺地減少日常活動(比如變懶得走路)。增加有氧運動(甚至只是多走路、多爬樓梯)能幫你把這部分消耗的熱量補回來,維持穩定的掉秤速度。

    💤 隱藏關鍵:睡眠篇 (Bill Campbell)

    Q8:睡不飽真的會變胖,而且特別胖在肚子嗎?

    A:是的! 研究發現,每天只睡 4 小時的人會吃下更多熱量,而且增加的脂肪有高達 11% 是危險的內臟脂肪(睡 9 小時的人完全沒增加)。

    Q9:如果我有嚴格控制熱量,睡不飽還有影響嗎?

    A:影響非常大!

    在同樣的熱量缺口下,睡 5.5 小時的人比睡 8.5 小時的人,流失的肌肉多了 1.6 倍,減掉的脂肪卻少了 2.3 倍。

    👉 結論:每天請務必睡滿 7-8 小時,否則減脂都是做白工。

    🧘‍♀ 心態與執行篇 (Laurin Conlin)

    Q10:為什麼我臉瘦了、手腳瘦了,肚子還是很大?我該放棄嗎?

    A:千萬別放棄!腹部通常是「最後」才會瘦下來的部位。

    這就是為什麼很多人會失敗的原因——他們在快要出成果的前一刻,因為覺得沒效而放棄,或者採取極端節食導致反彈。

    Q11:我該如何正確評估自己的減脂進度?

    A:不要只盯著肚子和體重計。

    請多觀察臉、肩膀、腿的變化,並結合「衣服有沒有變寬鬆」、「照鏡子體態有沒有變好」、「精神有沒有變好」等多重指標。給身體一點時間,保持耐心。

    💡 一句話總結這支影片的減肚指南:

    「控制總熱量 + 吃夠蛋白質 + 規律重量訓練 + 每天多走路 + 睡滿 7 小時 + 保持耐心等待腹部最後瘦下來。」

  3. Four months ago I weighed 194lbs. I went on GLP shots combined with walking nearly everyday and some weightlifting. I have lost 40lbs and lost much of my belly fat. My blood pressure is now normal and I don't take any BP medicine anymore. I am currently 5'6'/155 pounds and look and feel much better. The only negative is that my clothes don't fit me anymore.

  4. This video is absolutely fantastic! 🔥 Unlike those typical videos that just have you doing endless ab workouts, you brought in five top experts to break everything down in a way that is both scientific and easy to understand. 🧠💡

    What impressed me the most was the link between sleep and increased visceral fat 😴, as well as Alan Aragon's list of 20 favorite foods 🥗. Every piece of advice is scientifically backed, practical, and easy to implement without feeling restrictive. That final reminder about consistency was a great touch! 🎯

    A huge thank you to Jeremy and the entire team for putting so much effort into creating such a well-researched and incredibly valuable video. Keep up the great work! 🚀💪❤

  5. Great breakdown! One thing I have learned is that consistency matters more than chasing quick fixes. I also use the AlterMe Ring to keep an eye on my activity, sleep, and recovery, it helps me stay on track with healthier habits.

  6. You can drop tons of weight and if exercise is not part of your routine you will be left with lots of stomach fat which is very frustrating! I’ve been there where body core exercises and lots of walking the body looked incredible! I’ve also lost weight without exercise and the stomach fat practically looks the same which is worst because you would think the stomach fat would have disappeared with the weight lost! Exercise is a must! Good luck

  7. Interval sprints 20 minutes twice a week worked for me and other guys who did he same. My profile: already exercising, reasonable diet, fit, but with a slight gut.

  8. I am currently taking classes on Strength and conditioning for my sport science course and we learned that brisk walking or light jogging burns fat more efficiently than intense cardio that switches to burning carbohydrates. So light jogging or brisk walking for 30min everyday makes a huge difference in burning your fat.
