Trinny Woodall revealed how she struggles with losing weight too easily in a candid Instagram video on Monday. 

The Trinny London founder, 61, wore a sparkly silver gym top and light grey skimpy bottoms as she lifted the lid on the secrets behind ‘feeling healthy’ in her 60s.

She focussed on the importance of getting the right amount of protein, as well as the shock of losing 4kg after suffering from an illness, in a clip which also featured her personal trainer Nathalie Hayward.

The businesswoman said that her ‘shrivelled’ bottom made her feel like an ‘old elephant’ rather than a ‘strong bull’.

In a detailed caption, she explained how she had been looking to take in more protein lately.

She said: ‘I’m not one to talk about weight because for me it’s about strength and definitely the maintenance of protein as you go down the path of life. 

‘But today I am I have always had a high metabolism and I have always been what some people might define as thin – What I don’t love is when I lose weight especially after being ill and I can lose it quickly- what I notice is the change in my body. 

‘Muscle needs daily protein and muscle keeps my bones protected – it gives structure to my skin and it gives me physical and mental strength. It is harder as you get older to maintain muscle mass, but it is so important. 

‘I am now doubling up my protein, Natalie and I are going to go on a mission to really help strength and muscle in the right place to support different parts of my body., and hopefully to lift my slightly elephant bottom… there is a vanity matrix here though. 

‘I don’t want to be in a bikini with a saggy a**e. I’m just going admit that one. But most importantly when i get sick and lose weight it makes me feel so so vulnerable to not being strong in myself and how when I am physically strong it gives me such a mental strength. 

‘Ask yourself are you taking enough protein every day? You should really take double the kilos that you weigh especially as you reach menopause and beyond… Sometimes that’s really challenging. 

‘I generally start with a three egg omelette and I’m going to start incorporating a protein shake midmorning with some collagen. (I will share on stories which ones I’m using.) 

‘Lunch is going to be chicken and salad and the evening is going to be some fish and if I’m out for dinner, whatever is on the menu. At the beginning of the year I was really good at getting over 100 g a day into my diet but in the last few weeks I think I’ve been doing maximum about 60 or 80…. 

‘If you’re reading this and thinking I don’t know how to start my body feeling healthy and strong I have found great knowledge from @nathalie_hayward for what kind of supplementation to take and strength training – from Victoria @victoriawoodhall for giving myself space and time to understand the practice of yoga and how it can help me -@hubermanlab, the @glucosegoddess’

The advice to her followers comes after the entrepeneur showed off the results of her gruelling workout regime while filming a styling video for her Instagram page in March.

She looked incredible in a cropped beige underlayer which showed off her rock hard abs to perfection in the clip.

Trinny’s video was advising her followers how to style a pair of smart sweatpants, which she teamed with chunky boots and a sequin top.

The make-up mogul added a bomber jacket and earrings to complete the ensemble, while styling her hair in a bouncy blown out do with glam make-up from her own line.

Trinny openly talks about some of the health benefits she buys into as the reason she looks so good into her 60s – including regular workouts and consistent skincare.

She most recently revealed the secrets behind her noticeably radiant complexion after what she describes as a ‘very stressful’ few months.

Trinny, the powerhouse creator of beauty brand Trinny London, has seen her business skyrocket over the past few years with a rapidly growing following.

Torn between her many commitments, she was starting to really feel – and see – the impact of her hectic schedule.

Until she discovered her unexpected love for daily meditation – something she admits ‘wasn’t for her’ but now describes as ‘profound’.

She told FEMAIL: ‘I lead quite a stressed life and I was realising that stress, medically, is a really sh**ty place to get to for your body. It just is. It will affect you physically and medically.

‘So I thought I would take control before I let stress affect my body in a negative way.

‘I had two people come into my life and I noticed such a profound difference in how they were [after meditating]. One of them I thought had had a facelift, and the other was just so much easier to sit and chat to.’

Inspired, Trinny started getting up half an hour earlier each morning and spend 20 minutes meditating with a mantra. She then finds time for a second 20-minute block in the afternoon – even if it’s in the bathroom at her office.

‘I’ve been doing it for four weeks now and I really feel a shift. When you’re stressed, from an aesthetic perspective, it shows on your face,’ she said.

‘I feel so much calmer now.’
